There are several interesting features. The galaxy contains a massive black hole 140 million times greater than our sun. The black hole is surrounded by a ring replete with new star formation. The ring is lit by an influx of material moving towards the central bar of the galaxy. The galaxy contains four optical jets (one of which is extremely faint) that seem to emanate from the nucleus region. Studies have determined the jets are not emissions but are made up of stars. There are two satellite galaxies, NGC 1097 A and B. A is a peculiar galaxy which is orbiting only 42000 light years from the center of NGC 1097 while B is a dwarf galaxy which was discovered by emissions and has not been well studied.

It is one of the closest galaxies to the Local Group, and probably lies between the latter and the Sculptor Group. It is the brightest of the five main spirals in the direction of the Sculptor Group. It shares many characteristics of the Triangulum Galaxy that can be seen here: https://www.hansonastronomy.com/m33 It is 94,000 light-years in diameter, somewhat smaller than the Milky Way.

Recognized as one of the brightest radio sources, NGC 1316 exhibits visual evidence of having originated from mergers involving gas-rich spiral galaxies roughly three billion years ago. Ripples, Loops, and Arcs: Faint, extensive shells and ripples comprising stars and gas are observable in the galaxy’s outer regions, indicating tidal disruptions characteristic of previous merger events. Dust Lanes: The presence of complex and pronounced dark dust lanes represents remnants of gas and dust acquired from the integrated spiral galaxies. Globular Clusters: Studies of the surrounding globular cluster system further substantiate this history. Astronomers have identified fewer low-mass clusters near the center—where destructive collisions would occur—as well as an abundance of atypical young, metal-rich clusters formed during starburst episodes initiated by the merger. In summary, NGC 1316 serves as an instructive model for the formation of giant elliptical galaxies through sequential mergers with smaller, gas-rich systems over extensive cosmic timescales. These merger events likely fueled its central black hole, leading to its radio-galaxy activity.

This remarkable image highlights a structure reminiscent of octopus arms, with its extensions radiating in multiple directions. The overall appearance is both impressive and visually distinctive. NGC 1672 exemplifies a barred spiral galaxy, which is distinct from typical spiral galaxies in that its spiral arms do not extend continuously into the galactic center. Rather, these arms are anchored to both ends of a linear stellar bar encircling the nucleus. Multiple ionized hydrogen regions are also discernible.

However, despite its proximity, it is probably just beyond the Local Group, which is a loose collection of 30 or so galaxies within 2 or 3 million light years of the Milky Way. Apart from the Milky Way and the similarly massive M31 galaxy in Andromeda, most of our immediate extra-galactic neighbors are light-weight collections of stars and gas like IC 5152, though few (except the Large Magellanic Cloud) show such strong evidence of recent star formation.

Along with its neighbor NGC 300, it is one of the closest galaxies to the Local Group, probably lying between the Milky Way and the Sculptor Group. It is likely that NGC 55 and its neighbor NGC 300 orbit each other and form a gravitationally bound pair. Along with NGC 300, NGC 55 is part of the Local Group of Galaxies that also includes the Andromeda galaxy (M31), the Large and Small Magellanic Clouds, and 40 other galaxies. NGC 55 is nearly edge-on and appears asymmetrical, like a cigar. Its bulge is diffuse, broad, and somewhat elongated. The bright core is crossed with clouds of gas and dust, and it has a lot of pinkish active star forming regions, and young blue star clusters. Among all these stars are over a hundred Cepheid Variables. NGC 55 is thought to be like our galactic neighbor, the Large Magellanic Cloud (LMC), although the LMC is seen face-on, whilst NGC 55 is edge-on.

NGC 5248 is a prominent spiral galaxy located within the constellation Boötes. Positioned approximately 50 million light-years from Earth, it is considered relatively close in astronomical terms. One of the notable features of NGC 5248 is the presence of a large ring of gas and dust surrounding the central bulge. This ring, known as a "pseudo-ring," is believed to have formed due to gravitational interaction between NGC 5248 and another nearby galaxy. The pseudo-ring is an active site of star formation, where many new stars are being created. NGC 5248 also contains a supermassive black hole at its center, estimated to have a mass of around 300 million times that of our Sun. This black hole is surrounded by a disk of gas and dust, which emits radiation as the material spirals toward the black hole. Spiral galaxies like NGC 5248 are significant for understanding cosmic formation and evolution. They are believed to originate from the mergers and interactions of smaller galaxies, and their study provides vital information on the mechanisms driving galactic development and the broader processes shaping the universe.

One notable instance here is revealed an intricate galactic portrait despite the presence of excessive satellite trails. NGC 5364, positioned in the left center, is a spiral galaxy situated within the constellation Virgo. It features distinctive swirling arms and a luminous core, categorizing it as a grand design spiral galaxy. Grand design spiral galaxies are characterized by their prominent, well-defined arms that extend outward from a distinct core. This classification is rare, with only ten percent of spiral galaxies fitting this category. NGC 5364 exhibits some asymmetrical in its arms compared to other grand design spirals. This irregularity is likely a result of interactions with the nearby lenticular galaxy NGC 5363, located at the right center. Known colloquially as "The Alligator's Eye", is distinguished by its dust lanes and is approximately 63 million light years away. NGC 5364 is approximately 67 million light years distant, while NGC 5360, another lenticular galaxy situated at the lower left, is around 64 million light years away.

We decided it was time to see what we could do with the same data set years later. Here is the Result. NGC 3718 also known as ARP 214 is located 52 million light years away in Ursa Major. The galaxy is highly unusual. It is a highly disturbed galaxy that was initially thought to be a lenticular galaxy but is now considered to likely be a spiral galaxy due to the faint arm extensions that are apparent in the image. There are however certain characteristics that are like a polar ring galaxy. If that wasn’t enough the twisted shape is certainly due to interactions with NGC 3729.

Extracting the magnificent Ha emission of this wonderful galaxy which is hidden due to the significant obscuration by these stars. I aimed to highlight the HA in this image. It was challenging to reveal, but it was worth the effort. NGC 3109 is classified as a Magellanic type irregular galaxy around 4.5 million light years from Earth, but it may be a small spiral galaxy. If it is a spiral galaxy, it would be the smallest in the Local Group. NGC 3109 has a mass of about 2.3×10 ^9 times the mass of our Sun, of which 20% is in the form of neutral hydrogen. The galaxy is oriented edge-on from our point of view, and but may contain a disk and a halo. The disk appears to be composed of stars of all ages, whereas the halo contains only very old and metal-poor stars. There is no sign of galactic nucleus. From measurements of the neutral atomic hydrogen in the galaxy, it has been found that the disk of NGC 3109 is warped. The warp has the same radial velocity as gas in the Antlia Dwarf galaxy, Astronomers believe that the two galaxies had a close encounter around one billion years ago.

Also known as NGC 1068, its very bright core is well studied by astronomers exploring the mysteries of super massive black holes in active galaxies. While M77 is also seen at x-ray, ultraviolet, infrared, and radio wavelengths, this visible light image highlights another remarkable aspect of the galaxy. In the picture it shows outer faint details, following spiral arms and structures that reach far beyond the galaxy's brighter central regions. Including the fainter outskirts, the galaxy's diameter is well over 100 thousand light-years at M77's estimated distance, making it larger than our own spiral Milky Way. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1741187800716-KU477OPIRLGC67BH3X32/image-asset.jpeg Galaxies - NGC 3511 and 3513 NGC 3511-13 NGC 3511(top left) is an intermediate spiral galaxy located in the constellation Crater. It is 45 million light years from Earth, which, given its apparent dimensions, means that it’s about 70,000 light years across. The structure includes two highly diffuse, thick, and irregular spiral arms originating from the bulge, accompanied by additional fragmented spiral arms. Dark dust lanes cross the spiral pattern. The bulge looks elliptical and weak. At the galaxy's center is a supermassive black hole. Originally classified as a type 1 Seyfert galaxy, this galaxy has been reclassified as an HII region galaxy due to its narrow emission lines. NGC 3511 forms a pair with NGC 3513 which is a barred spiral galaxy which lies 10.5 arcminutes away. NGC 3513(bottom right) is a barred galaxy with a thin high-surface-brightness bar. The bar ends feature two distinct spiral arms with star formation knots and HII regions, creating a patchy appearance. The two galaxies form a small group, known as the NGC 3511 group, which also includes the galaxy ESO 502-024. A faint, narrow hydrogen bridge appears to connect the two galaxies. Additional hydrogen-alpha data is required to confirm this observation.

IC 1613 (Caldwell 51) is a dwarf irregular galaxy located in the constellation Cetus and was discovered by Max Wolf in 1906. This galaxy is a member of the Local Group of galaxies and has a morphological classification of IBm (Irregular Barred - Magellanic type). Irregular galaxies are those that don't fit into the Hubble sequence of galaxy classification and often have chaotic structure, lack spiral arms and no nuclear bulge. It's believed that these galaxies are shaped so because of gravitational influences from passing galaxies or larger neighboring ones. IC1613 has a very low surface brightness and so little dust that background galaxies can been seen behind it in this image. The center has a visible bar like structure and overall has several star forming regions as evident by the red HIII regions surrounding hot blue O/B stars. Star ages range from 20 million to 10 billion years old. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1730496762520-52NLCBG1LXAVKHDQMB94/M61APODCrop.jpg Galaxies - Messier 61 (NGC 4303) SSRO Messier 61 (also known as NGC 4303) is a very bright barred spiral galaxy of some 100,000 light-years across, located only about 52.5 million light-years away from Earth in the constellation of Virgo (the Virgin), while it is receding from us at about 1566 kilometers per second. This grand design galaxy spiral (a spiral galaxy with prominent and well-defined spiral arms that extend clearly around the galaxy) is one of the largest members of the Virgo Cluster, a cluster of approximately 1300 (and possibly up to 2000) galaxies held together by gravity. This cluster forms the central region of the Virgo Supercluster (or Local Supercluster), an even bigger gathering of galaxies. Messier 61 is classified as a starburst galaxy and has an Active Galactic Nucleus. The energy source of an Active Galactic Nucleus is believed to originate in mass accretion by a supermassive black hole within the nucleus of the galaxy. Messier 61 probably has a supermassive black hole with a mass around 5 million times that of our Sun on its center. In this image, its spiral arms can be seen in stunning detail, swirling inwards to the very center of the galaxy, where they form a smaller, intensely bright spiral. In the outer regions, these vast arms are sprinkled with bright blue regions where new stars are being formed from hot, dense clouds of gas. The high star formation across Messier 61’s disk is perhaps due to interactions with her satellite galaxies NGC 4292 and NGC 4303B. The intensely bright spiral is a nuclear starburst ring some 730 light years from the nucleus, formed by several massive star-forming regions which contain massive hot stars with an age range between 5 and 25 million years old. The starburst ring may be associated with a second bar much smaller than the main one of this galaxy. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1730495904205-ZXNI4EDYV751YHLGBW9D/image-asset.jpeg Galaxies - NGC 488 NGC 488 is a spiral galaxy seen face on 90 million light years away in Pisces.

The grand spiral galaxy can be found toward the northern constellation of the Great Bear (Ursa Major). This superbly detailed image reveals M81's bright yellow nucleus, blue spiral arms, tell tale pinkish star forming regions, and sweeping cosmic dust lanes with a scale comparable to the Milky Way. Hinting at a disorderly past, a remarkable dust lane actually runs straight through the disk, to the left of the galactic center, contrary to M81's other prominent spiral features. The errant dust lane may be the lingering result of a close encounter between between M81 and its smaller companion galaxy, M82. Scrutiny of variable stars in M81 has yielded one of the best determined distances for an external galaxy -- 11.8 million light-years. M81's dwarf companion galaxy Holmberg IX can be seen just above the large spiral. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1493921425269-GGVY1MYELD1IMBXTOGHX/M51-CropDoneHA.jpg Galaxies - M51 With HA added https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1722805317875-N9AD82ZB0XCAYHMQXDL4/100%25CropNGC660.jpg Galaxies - NGC 660 - The Polar Ring Galaxy Explanation APOD: NGC 660 is featured in this cosmic snapshot. Over 40 million light-years away and swimming within the boundaries of the constellation Pisces, NGC 660's peculiar appearance marks it as a polar ring galaxy. A rare galaxy type, polar ring galaxies have a substantial population of stars, gas, and dust orbiting in rings strongly tilted from the plane of the galactic disk. The bizarre-looking configuration could have been caused by the chance capture of material from a passing galaxy by a disk galaxy, with the captured debris eventually strung out in a rotating ring. The violent gravitational interaction would account for the myriad pinkish star forming regions scattered along NGC 660's ring. The polar ring component can also be used to explore the shape of the galaxy's otherwise unseen dark matter halo by calculating the dark matter's gravitational influence on the rotation of the ring and disk. Broader than the disk, NGC 660's ring spans over 50,000 light-years. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1720533099365-7SQXJTPRY8UWVUMRF2NV/image-asset.jpeg Galaxies - NGC 3981 NGC 3981 is about 65 million light years from Earth, but even at that great distance it is considered a neighbour of our own galaxy, the Milky Way. The large stars in the image’s foreground are stars in the Milky Way. Because NGC 3981 is inclined towards Earth, astronomers are able to look right into the center of the galaxy. The bright center of the galaxy is dominated by a super-massive black hole (SMBH). The image shows the vast and delicate-looking spiral arms of the galaxy, which are star-forming regions full of dust. The disc itself is lit up with a host of hot young stars. Some of the spiral arm appears stretched out and misshapen, possibly due to an encounter with another galaxy at some time in the distant past. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1677683741604-L76M73WNFU0KZW8SLLPU/image-asset.jpeg Galaxies - NGC 3169 "The Scorpion Galaxy" NGC 3169 “The Scorpion Galaxy” Spiral galaxy NGC 3169 appears to be ready for the strike. Well, only with a bit of imagination. Spiral galaxy NGC 3169 appears to be unraveling in this cosmic scene, played out some 70 million light-years away just below bright star Regulus toward the faint constellation Sextans. Its beautiful spiral arms are distorted into sweeping tidal tails as NGC 3169 (left) and neighboring NGC 3166 (right) exhibits distortion in its dust lanes as they interact gravitationally, eventually probably tearing each other apart. This is often the case for proximate galaxies in the local universe. In fact, drawn out stellar arcs and plumes, indications of gravitational interactions, seem rampant in the deep and colorful galaxy group photo. Smaller, dimmer NGC 3165 at bottom right. NGC 3169 is also known to shine across the spectrum from radio to X-rays, harboring an active galactic nucleus that is likely the site of a supermassive black hole.

It’s often referred to as the hamburger galaxy. I have to say if I’m going to eat a burger from fast food place it will be Culvers! And this one looks delicious, must be a bacon butter deluxe. It’s also one of the galaxies in the Leo triplet and has a tidal tail that stretches 300,000 light years seen in a nice detail in this image. While classified as unbarred, there is some speculation that it is a barred galaxy due to the X shaped bulge in the central portion. Bar formation is often triggered by interaction with other galaxies, and 3628 is interacting with the other two galaxies in the triplet. The galaxy features numerous dust lanes and several obvious regions of active star formation. There are many distant background galaxies throughout the image. Image Processing and Calibration: Mark Hanson Data: Martin Pugh Enjoy, Mark NGC 3628, also known as the Hamburger Galaxy or Sarah's Galaxy, is an unbarred spiral galaxy about 35 million light-years away in the constellation Leo. It was discovered by William Herschel in 1784. It has an approximately 300,000 light-years long tidal tail. Along with M65 and M66, NGC 3628 forms the Leo Triplet, a small group of galaxies. Its most conspicuous feature is the broad and obscuring band of dust located along the outer edge of its spiral arms, effectively transecting the galaxy to the view from Earth. Amateur small equipment has demonstrated to be competitive tools to obtain ultra-deep imaging of the outskirts of nearby massive galaxies and to survey vast areas of the sky with unprecedented depth. Over the last decade, amateur data have revealed, in many cases for the first time, an assortment of large-scale tidal structures around nearby massive galaxies and have detected hitherto unknown low surface brightness systems in the local Universe that weren’t detected so far by means of resolved stellar populations or Hi surveys. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1711452708656-KBWFTOVUAR4VOGHSL43F/image-asset.jpeg Galaxies - Arp 271 Arp 271 The Tender Dance Located about 130 million light-years away, the Arp 271 pair is about 130,000 light-years across. It was originally discovered in 1785 by William Herschel. It is speculated that the Milky Way will undergo a similar collision in about five billion years with the neighbouring Andromeda Galaxy, which is currently located about 2.6 million light-years away in the constellation Virgo. Arp 271 comprises galaxies NGC 5426 and NGC 5427, two similar spiral galaxies that glide past each other in a cosmic dance that is choreographed by gravity. It is uncertain whether the galaxies will eventually collide. They will continue to interact for tens of millions of years, creating new stars due to the mutual gravitational attraction between the galaxies, seen here are obvious signs of interaction by the bridge of stars already connecting the two. Our own Milky Way Galaxy will undergo a similar collision in the far future with the Andromeda galaxy, which is now located about 2.6 million light years away from the Milky Way.

Barred spiral NGC 5101 (middle left) and nearly edge-on system NGC 5078 (middle right) are separated on the sky by about 0.5 degrees or about the apparent width of a full moon. Found within the boundaries of the serpentine constellation Hydra, both are estimated to be around 90 million light-years away and similar in size to our own large Milky Way galaxy. In fact, if they both lie at the same distance their projected separation would be only 800,000 light-years or so. That's easily less than half the distance between the Milky Way and the Andromeda Galaxy. NGC 5078 is interacting with a smaller companion galaxy, cataloged as IC 879, seen just right of the larger galaxy's bright core. Even more distant background galaxies are scattered around the colorful field. Some are even visible right through the face-on disk of NGC 5101. But the prominent spiky stars are in the foreground, well within our own Milky Way. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1706449243999-C1GR42UT6XX27TRP85T8/NGC+2090-Selby+HansonsThumb.jpg Galaxies - NGC 2090 in Columba NGC 2090 in Columba NGC 2090 is an infrequently imaged spiral galaxy located 40 million light years away in Columba.

NGC 2090 was one of 18 galaxies that were part of the HST Extragalactic Distance Scale Key Project to better define the value of the Hubble constant. The sparse nature of the galaxy’s arms allowed The Hubble Space Telescope to resolve stars leading to a more accurate red shift calculation.

It was discovered by James Dunlop in 1826 and subsequently entered into the New General Catalogue as NGC 1291 by Johan Ludvig Emil Dreyer. John Herschel then observed the same object in 1836 and entered it into the catalog as NGC 1269 without realizing that it was a duplicate. This galaxy was cited as an example of a "transitional galaxy" by NASA's Galaxy Evolution Explorer team in 2007.The galaxy NGC 1291 is about 12 billion years old—and that’s old. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1702949124954-K7NKP9V93PHPMTL9XLOW/NGC259T.jpg Galaxies - NGC 289 About 70 million light-years distant, gorgeous spiral galaxy NGC 289 is larger than our own Milky Way. Seen nearly face-on, its bright core and colorful central disk give way to remarkably faint, bluish spiral arms. The extensive arms sweep well over 100 thousand light-years from the galaxy's center. At the top left in this sharp, telescopic galaxy portrait the main spiral arm seems to encounter a small, fuzzy elliptical companion galaxy interacting with enormous NGC 289.

It’s one of the largest and closest barred spirals galaxies to us. It has hosted many supernova explosions. At least six (likely 7)of these were observed supernovae and nearly 300 supernovae remnants. Its center is mysterious and unusual; the supermassive black hole at its heart is not alone. This striking galaxy displays a phenomenon known as a double nucleus. The double Nucleus does not mean it has 2 black holes but rather a single supermassive black hole with a large lopsided disk of stars orbiting which makes it look like dual nucleus. M 83 has a "bar" of stars slicing through its center, leading to its classification as a barred spiral. Our own Milky Way also belongs to this category as well. These bars are thought to act a bit like a Chanel, funneling gas inwards towards the galaxy's core. This gas is then used to form new stars that feed the galaxy's black hole. Here we see the Hydrogen channel only Where the detail Is quite different from the color channels. This was continuum subtracted from the red channel to give a much more realistic view.

Measured to be only 11 million light-years distant it is nearby though. Tilted nearly edge-on as seen from our perspective, it dominates this telescopic field of view toward the southern constellation Cetus. The pronounced dark void on the bottom side of the galaxy's disk recalls for some its popular name, the Needle's Eye galaxy. Many background galaxies are visible in this sharp galaxy portrait, including the remarkable string of four galaxies just below and right of NGC 247 known as Burbidge's Chain. Burbidge's Chain galaxies are about 300 million light-years distant.

Its size (about 100,000 light-years) makes it like our own galaxy, the Milky Way. It is called a "grand design" galaxy because of its well defined spiral arms. Two supernovae and two ultraluminous X-ray sources have been discovered in NGC 7424. On December 10, 2001, the Australian amateur astronomer Robert Evans discovered SN 2001ig, a rare Type IIb supernova on the outer edge of NGC 7424. At the time of its maximum, the supernova was only three times fainter than the whole galaxy. It must have been a splendid firework! It is now believed that indeed this supernova arose from the explosion of a very massive star, a so-called Wolf-Rayet star, which together with a massive hot companion belonged to a very close binary system in which the two stars orbited each other once every 100 days or so. The companion probably periodically stripped the outer hydrogen-rich envelope of the progenitor, accounting for the observed spectral changes, or the periodic mass loss was a result of the intense stellar wind these stars produce.

The background galaxies lie at a much greater distance than the triad, which is about 60M light-years away. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1689624089419-5KXPFPNIZNUH06UX4JA7/image-asset.jpeg Galaxies - NGC 2935 NGC 2935 NGC 2935 is a barred spiral galaxy 125 million light years away in Hydra.

It took Bindon Stoney using Lord Rosse's 72" in 1851 to discover the smaller galaxy in the pair which became NGC 1889. Arp catalogued the pair as Arp 123 in his group of "Ellipticals close to and perturbing spirals". NGC 1888 does look as if it is being distorted by an encounter with extended spiral arms. The galaxy does have a spiral arm on the opposite side to NGC 1889 which contains lots of young blue stars. The pair are almost certainly in the early throws of a merger.

The lovely island universe resides in the large Virgo cluster of galaxies. Colors in this well-composed, cosmic portrait shows many young, bluish star clusters along the galaxy's sweeping spiral arms. Its broad arms are distorted by gravitational interaction with a fellow Virgo cluster member, giant elliptical galaxy NGC 4697. NGC 4697 is beyond this frame above and to the left. The field is littered with many galaxies and clusters of galaxies as well. Of course, the individual, colorful, spiky stars in the scene are much closer, within our own Milky Way galaxy.

First, spiral galaxy M94 has an inner ring of newly formed stars surrounding its nucleus, giving it not only an unusual appearance but also a strong interior glow. A leading origin hypothesis holds that an elongated knot of stars known as a bar rotates in M94 and has generated a burst of star formation in this inner ring. Observations have also revealed another ring, an outer ring, one that is more faint, different in color, not closed, and relatively complex. What caused this outer ring is currently unknown. M94, pictured here, spans about 45,000 light years in total, lies about 15 million light years away, and can be seen with a small telescope toward the constellation of the Hunting Dogs (Canes Venatici). https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1687266067479-ZZV0VXEJ42C1O71ZQN48/image-asset.jpeg Galaxies - NGC 6384 NGC 6384 is a barred spiral galaxy of about 150.000 light-years across that lies some 80 million light-years away in the constellation of Ophiuchus (The Serpent Bearer). It is speeding away from us at roughly 1680 kilometers per second. The galaxy has blue spiral arms laced with dark dust lanes and a yellowish core. Star formation in the center is being fueled by the galaxy’s bar structure; astronomers think such galactic bars funnel gas inwards, where it accumulates to form new stars. Many stars have already come to the ends of their lives in NGC 6384, but in 1971, we could witness one of its stars explode as a Type Ia supernova, which stood out against the bright foreground stars. This occurs when a compact star that has ceased fusion in its core, called a white dwarf, increases its mass beyond a critical limit by gobbling up matter from a companion star. A runaway nuclear explosion then makes the star suddenly as bright as a whole galaxy. Supernova explosions are enriching the intergalactic gas with elements like oxygen, iron, and silicon that will be incorporated into new generations of stars and planets. The positioning of NGC 6384, not far from the center of the Milky Way in the sky, means that it is somewhat obscured by our galaxy’s dust and stars. Combined with the galaxy’s low surface brightness, NGC 6384 is a bit of a challenging target for astrophotographers. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1686146703841-PKTEAYEO1P5QUDOVBIWM/M74Done.jpg Galaxies - M 74 Messier 74 (also known as NGC 628) is a spiral galaxy in the constellation Pisces. It is at a distance of about 32 million light-years away from Earth. The galaxy contains two clearly defined spiral arms and is therefore used as an archetypal example of a grand design spiral galaxy. The galaxy's low surface brightness makes it the most difficult Messier object for amateur astronomers to observe. However, the relatively large angular size of the galaxy and the galaxy's face-on orientation make it an ideal object for professional astronomers who want to study spiral arm structure and spiral density waves. It is estimated that M74 is home to about 100 billion stars https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1685025597289-GXUMGW0TZ9V5OW1NRFF5/image-asset.jpeg Galaxies - NGC 2207 NGC 2207 “Things that go bump in the night” NGC 2207 and IC 2163 are shown here in a near collision. Located approximately 80 million light years away from Earth the powerful tidal forces from NGC 2207 have caused major distortions in the shape of IC 2163 the smaller galaxy on the right. The interaction has caused streams of stars and gas to extend as far as 100 thousand light years from IC 2163. The near collision is estimated to have taken place around 40 million years ago and given the gravitational influence of NGC 2207 it is very likely the IC 2163 will be pulled back for another round and in a billion or so years the galaxies will merge. The tidal streams seen in the image will over time likely become star forming regions.

Most galaxies are members of clusters of galaxies. In these, they move around among each other in a mostly slow and graceful ballet. But every now and then, two or more of the members may get too close for comfort – the movements become hectic, sometimes indeed dramatic, as when galaxies end up colliding. This image shows an example of such a cosmic tango. As dramatic and destructive as this may seem, such an interaction event is also an enrichment, a true baby-star boom. A cosmic catastrophe like this one normally results in the formation of many new stars. This is obvious from the blueish nature of the spiral arms in NGC 6769 (lower right) and NGC 6770 (lower left) and the presence of many sites of star forming regions. The two upper galaxies, NGC 6769 and NGC 6770 are of equal brightness and size, while NGC 6771 (above) is about half as bright and slightly smaller. All three galaxies possess a central bulge of similar brightness. They consist of elderly, reddish stars and that of NGC 6771 is remarkable for its “boxy” shape, a rare occurrence among galaxies. All three galaxies are barred spiral galaxies: NGC 6769 with very tightly wound spiral arms, while NGC 6770 has two major spiral arms, one of which is rather straight and points towards the outer disk of NGC 6769. NGC 6770 is also peculiar in that it presents two comparatively straight dark lanes and a fainter arc that curves towards the third galaxy, NGC 6771. Stars and gas have been stripped off NGC 6769 and NGC 6770, starting to form a common envelope around them, in the shape of a Devil’s Mask. There is also a weak hint of a tenuous bridge between NGC 6769 and NGC 6771. All of these features testify to strong gravitational interaction between the three galaxies. The warped appearance of the dust lane in NGC 6771 might also be interpreted as more evidence of interactions. Moreover, NGC 6769 and NGC 6770 are receding from us at a similar velocity of about 3800 kilometers per second while that of NGC 6771 is slightly larger, 4200 kilometers per second. NGC 6769 was home to at least two supernovae: SN 1997de and SN 2006ox. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1682865966606-RJEWS31E54XI3N7B4KBJ/CentA24-ChileT.jpg Galaxies - Centaurus A Galaxy Description by "Sakib Rasool" This dramatic galaxy portrait depicts the disturbed and peculiar galaxy NGC 5128 in the constellation of Centaurus. The result of a merger between an elliptical galaxy and a spiral galaxy, it displays a wide variety of kinematical features. It is the closest known active galaxy at 11 million light years. The remnant of the original spiral galaxy is represented by its central dust lane highlighted along its edges with the signatures of star formation such as blue star clusters and red emission nebulae. Many cosmic collisions between galaxies trigger a massive starburst of starforming activity as the neutral gas reservoir is increased and pressure and gravity compress gas clouds into active sites of starbirth. The original collision has also strewn small dust globules across the disk of the galaxy. This intergalactic encounter between two galaxies has also deformed the structure of the original elliptical galaxy and faint tidal shells envelop the galaxy. They were originally discovered by the astronomers David Malin and David Carter in the 1970's through special photographic amplification techniques. Their discovery prompted the publication of a catalogue of shell elliptical galaxies in 1983 and there are a few hundred known to belong to this category. Images with a wider field of view than this show multiple interlocking shells that extend even further. The origin of these shells are minor mergers with multiple smaller galaxies and are created by the disruption of orbits of captured stars. NGC 5128 is also known as Centaurus A and this particular naming scheme denotes the first radio source to be discovered in a particular constellation. As it has been detected by astronomers in observations made with radio telescopes, it belongs to another category of radio galaxies. Radio galaxies are so-called as they radiate more emission in radio than in optical. They are a type of active galactic nucleus (usually abbreviated to AGN). As the name suggests, galaxies that feature an AGN have an energetic nuclear region centered around a supermassive black hole. Although not immediately apparent, the AGN activity in Centaurus A is represented optically by a long filamentary jet, which can be seen north of the core. The jet arises from an outflow of gas that has built up in the accretion disk surrounding the supermassive black hole and its narrow appearance is the product of interacting magnetic fields associated with the black hole. This jet appears as an impressive bipolar outflow in x-ray and radio images. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1682558417991-ERBWIGPFRQE5ZU2QW6KY/image-asset.jpeg Galaxies - NGC 4027 NGC 4027 (also known as Arp 22) is a barred spiral galaxy approximately 83 million light-years away[2] in the constellation Corvus. It is also a peculiar galaxy because one of its spiral arms goes out more than the other. This is probably due to a galactic collision in NGC 4027's past. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1682447328017-VQ48FGG7IHH8DYAPN6IW/image-asset.jpeg Galaxies - NGC 7285 NGC 7285 and NGC 7284 (right and left respectively) are in the process of merging.

NGC 7284 is variously listed as a barred spiral or a Lenticular Galaxy while 7285 is classed as a spiral galaxy. There is a massive tidal stream extending around 200,000 light years resulting from the interaction. The pair are listed in the ARP catalog of peculiar galaxies as ARP 93.

I have to say this is one of the best amateur data sets I have worked with, and the results are quite amazing. NGC 2442 is located around 50 million light-years away in the constellation of Volans. The galaxy is 75,000 light-years wide and has quite a peculiar shape featuring two dusty spiral arms extending from a central bar that gives it a hook-like appearance. Given its appearance it is often referred to as “The Meat Hook Galaxy.” The galaxy’s distorted shape is most likely the result of a close encounter with a smaller galaxy sometime in the past. A considerable amount of IFN is present in the field proximate to the galaxy and the image shows faint star streams at the ends of the arms of the galaxy.

While classified as unbarred, there is some speculation that it is actually a barred galaxy due to the X shaped bulge in the central portion. Bar formation is often triggered by interaction with other galaxies, and 3628 is interacting with the other two galaxies in the triplet.

These "flocculent" spiral arms indicate that the recent history of star formation of the galaxy, known as NGC 2775, has been relatively quiet. There is virtually no star formation in the central part of the galaxy, which is dominated by an unusually large and relatively empty galactic bulge, where all the gas was converted into stars long ago. NGC 2275 is classified as a flocculent spiral galaxy, located 67 million light-years away in the constellation of Cancer. Millions of bright, young, blue stars shine in the complex, feather-like spiral arms, interlaced with dark lanes of dust. Complexes of these hot, blue stars are thought to trigger star formation in nearby gas clouds. The overall feather-like spiral patterns of the arms are then formed by shearing of the gas clouds as the galaxy rotates. The spiral nature of flocculents stands in contrast to the grand design spirals, which have prominent, well defined-spiral arms.

Also known as NGC 772, the island universe is over 100 thousand light-years across and sports a single prominent outer spiral arm in this detailed cosmic portrait. Its brightest companion galaxy, compact NGC 770, is toward the upper right of the larger spiral. NGC 770's fuzzy, elliptical appearance contrasts nicely with a spiky foreground Milky Way star in matching yellowish hues. Tracking along sweeping dust lanes and lined with young blue star clusters, Arp 78's large spiral arm is likely due to gravitational tidal interactions. Faint streams of material seem to connect Arp 78 with its nearby companion galaxies. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1665070883436-72CKLMA64R9CJKZ3AS49/image-asset.jpeg Galaxies - NGC 1097-1Meter NGC 1097 is a barred spiral galaxy 50 million light years away in Fornax.

Located a mere 60 million light-years away toward the chemical constellation Fornax, NGC 1365 is a dominant member of the well-studied Fornax galaxy cluster. This impressively sharp color image shows intense star forming regions at the ends of the bar and along the spiral arms, and details of dust lanes cutting across the galaxy's bright core. At the core lies a supermassive black hole. Astronomers think NGC 1365's prominent bar plays a crucial role in the galaxy's evolution, drawing gas and dust into a star-forming maelstrom and ultimately feeding material into the central black hole. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1665068671238-LCJOJZACH7N1NQW7XZIC/image-asset.jpeg Galaxies - NGC 6907 NGC 6907 is a spiral galaxy in Capricornus around 130 million light years away. The galaxy is only 3×2’ in the field of view and we were unable to find any other clear images that have been taken. The galaxy has two prominent spiral arms and an elliptical bulge which is offset towards the base of the arms. The galaxy also has a central bar. Of interest is NGC 6908 the small bright galaxy that appears embedded in the upper right portion of the galaxy in this image. This was originally thought to be a bright spot within NGC 6907, but has since with infrared studies been properly identified as a low luminosity lenticular galaxy situated further from us than NGC 6907. It appears that NGC 6908 passed through the disk of NGC 6907 and a stellar and gas bridge was formed between the two galaxies that has been observed as high velocity gas. It is estimated that NGC 6908 passed through the disk approximately 35 million years ago. Imaged in LRGB on our PlaneWave CDK 1000 at Observatorio El Sauce, Chile.

It forms an interacting pair with NGC 470 the spiral galaxy to the right and is classified in the Peculiar Galaxy catalog as ARP 227 and peculiar it is. NGC 474 has an unusual and complex series of shell layers and tidal streams that surround the central part of the galaxy and its core. The origin of the structure has been somewhat of a mystery, however it was recently postulated that the tidal features come from the accretion of a spiral galaxy that collided around 1.3 billion years ago and merged around 900 million years ago. Volume 660, April 2022 of AANDA in the Extragalactic Astronomy section theorizes that based on the phase-space wrapping model by Quinn the formation of the shells began by a nearly radial minor or intermediate merger of the two galaxies. The large galaxy disrupted the smaller secondary galaxy by tidal forces causing the release of stars which moved out at various radial velocities. The orbital period and position was then determined by pericentric velocities. In effect then the shells are density waves made of stars near the epicenters of their orbits and expand over time.

First discovered by William Herschel in 1785, the galaxy has numerous star streams and plumes associated with it which are probably the result of a merger with another spiral galaxy about 1 billion years ago. It may take another billion years for this merger to settle down. It was this odd shape that led to its inclusion in Arp’s catalogue of peculiar galaxies. The support for the merger scenario comes from the fact that there are two star like objects near the core of NGC 7727, one of which may be the core of the merging galaxy and the other the main core of NGC 7727. NGC 7727 does not seem to have a large reservoir of hydrogen gas to form new stars so it is probably going to become an elliptical galaxy in the future. Images from GALEX, an ultraviolet satellite, show very little star formation going on at the current time in NGC 7727 compared to its neighbor NGC 7724. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1662125971720-IXG2HUY26XQ09ESVYXSQ/NGC-6822T.jpg Galaxies - NGC 6822 Barnards Galaxy NGC 6822 (also known as Barnard's Galaxy, IC 4895, or Caldwell 57) is a barred irregular galaxy approximately 1.6 million light-years away in the constellation Sagittarius. Part of the Local Group of galaxies, it was discovered by E. E. Barnard in 1884 (hence its name), with a six-inch refractor telescope. It is one of the closer galaxies to the Milky Way. It is similar in structure and composition to the Small Magellanic Cloud. It is about 7,000 light-years in diameter. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1656700066303-8YB9ODIRCIZNUKQB6KAR/NGC4725APYMarkHanson.jpg Galaxies - NGC 4725 (Stellar Winds Observatory-Rancho Hidalgo)) NGC 4725 While most spiral galaxies, including our own Milky Way, have two or more spiral arms, NGC 4725 has only one. In this sharp color composite image, the solo spira mirabilis seems to wind from a prominent ring of bluish, newborn star clusters and red tinted star forming regions. The odd galaxy also sports obscuring dust lanes a yellowish central bar structure composed of an older population of stars. NGC 4725 is over 100 thousand light-years across and lies 41 million light-years away in the well-groomed constellation Coma Berenices. Computer simulations of the formation of single spiral arms suggest that they can be either leading or trailing arms with respect to a galaxy's overall rotation. Also included in the frame, sporting a noticably more traditional spiral galaxy look, is a more distant background galaxy.

The bizarre configuration could be caused by the chance capture of material from another galaxy by a disk galaxy, with the captured debris strung out in a rotating ring. Still, observed properties of NGC 2685 suggest that the rotating ring structure is remarkably old and stable. In this sharp view of the peculiar system also known as Arp 336 or the Helix galaxy, the strange, perpendicular rings are easy to trace as they pass in front of the galactic disk, along with other disturbed outer structures. NGC 2685 is about 50,000 light-years across and 40 million light-years away in the constellation Ursa Major. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1655831123823-8AGDBATBT06PBH7T51RI/image-asset.jpeg Galaxies - NGC 5746 “The Small Sombrero” NGC 5746 “The Small Sombrero” NGC 5746 is a barred spiral galaxy seen near edge on in Virgo.

It is part of the NGC 2217 Group of galaxies. It is classified as a barred spiral galaxy. A notable feature is the swirling shape of this galaxy. In its very concentrated central region we can see a distinctive, very luminous bar of stars within an oval ring. Further out, a set of tightly wound spiral arms almost form a circular ring around the galaxy. Central bars play an important role in the development of a galaxy. They can, for example, funnel gas towards the center of the galaxy, helping to feed a central black hole, or to form new stars.

Along with the smaller galaxy NGC 1531 this pair of interacting galaxies is located about 55 million light-years away from Earth in the southern constellation of Eridanus. NGC 1531 – the small galaxy with a bright core lies just above the center of its companion and is a lenticular dwarf galaxy around 20,000 light-years across. NGC 1532, the large galaxy is a nearly edge-on, deformed barred spiral galaxy about 180 thousand light-years across. While It may possess several dwarf companion galaxies, it is clearly interacting with NGC 1531. These two galaxies are gravitationally bound and very close to each other. As a result, NGC 1532 became distorted: one of its spiral arms is warped and plumes of dust and gas are visible above its disk. The interaction has also triggered bursts of star formation in both galaxies. This is obvious in NGC 1532 where a whole new generation of massive stars has been born which are visible in the spiral arms. In addition, some material may have migrated to NGC 1531, which shows an S-shaped dust lane crossing its center. Over time the gravitational interaction of the two galaxies will tear NGC 1531 apart and merge its remains with NGC 1532.

NGC 1808 is undergoing so much star formation it has been deemed a starburst galaxy. The galaxy is moving away from us at 995 kilometers per second. NGC 1808 is distinguished by a peculiar and complex nucleus, an unusually warped disk, and strange flows of hydrogen gas out from the central regions. The galaxy’s center is the hotbed of vigorous star formation. The starburst must be at least 50 million years old, and can be no older than 100 million years old. Star formation has been rapid and continuous. Without an influx of fresh molecular gas into the central region, the star forming activity can only be maintained at this rate for another 6 to 20 million years. NGC 1808 is called a barred spiral galaxy because of the straight lines of star formation on both sides of the bright nucleus. This star formation may have been triggered by the rotation of the bar, or by matter which is streaming along the bar towards the nuclear region (feeding the starburst). Filaments of dust are being ejected from the core into the galactic halo by massive stars that have exploded as supernovae in the starburst region.

NGC 1792 is in the southern constellation of Columba. It was discovered by the Scottish astronomer James Dunlop on October 4, 1826. NGC 1792’s appearance is quite energetic looking, due to the rich neutral hydrogen nature of this galaxy new stars are forming quite rapidly. It’s both a spiral galaxy, and a starburst galaxy. Stars within these starburst galaxies are forming at quite extraordinary rates. It can be more than 10 times faster in a starburst galaxy than in a galaxy like our own the Milky Way. When galaxies have a large reservoir of gas, like NGC 1792, these short-lived starburst phases can be sparked by galactic events such as mergers and tidal interactions. One might think that these starburst galaxies would easily consume all their gas in a large forming event, However, supernova explosions and intense stellar winds produced in these powerful starbursts can inject energy into the gas and disperse it, this halts the star formation before it can completely deplete the galaxy of all its fuel. www.hansonastronomy.com Taken from SWOS in El Sauce, Chile 24” PlaneWave CDK (LRGBHA) Thank you, Mark Hanson https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1636735523081-RPS88MHZBO2X40AMG704/NGC-253+100perThumb2.jpg Galaxies - NGC 253 – Sculptor or Silver Dollar Galaxy The Sculptor Galaxy (also known as the Silver Coin, Silver Dollar Galaxy, NGC 253, or Caldwell 65) is an intermediate spiral galaxy in the constellation Sculptor. The Sculptor Galaxy is a starburst galaxy, which means that it is currently undergoing a period of intense star formation. Explanation Via APOD: NGC 253 is one of the brightest spiral galaxies visible, but also one of the dustiest. Dubbed the Silver Coin for its appearance in small telescopes, it is more formally known as the Sculptor Galaxy for its location within the boundaries of the southern constellation Sculptor. Discovered in 1783 by mathematician and astronomer Caroline Herschel, the dusty island universe lies a mere 10 million light-years away. About 70 thousand light-years across, NGC 253, pictured, is the largest member of the Sculptor Group of Galaxies, the nearest to our own Local Group of galaxies. In addition to its spiral dust lanes, tendrils of dust seem to be rising from a galactic disk laced with young star clusters and star forming regions in this sharp color image. The high dust content accompanies frantic star formation, earning NGC 253 the designation of a starburst galaxy. NGC 253 is also known to be a strong source of high-energy x-rays and gamma rays, likely due to massive black holes near the galaxy's center.

Looks like a swarm of flying insects. NGC 4753 is a lenticular galaxy located about 60 million light-years away in the constellation of Virgo. NGC 4753 was discovered by astronomer William Herschel on February 22, 1784. It is notable for having distinct dust lanes that surround its nucleus. The galaxy is a member of the Virgo II Groups, an extension of the Virgo Cluster. The distribution of dust in NGC 4753 lies in an inclined disk wrapped several times around the nucleus. The material in the disk may have been accreted from the merger of gas rich dwarf galaxy. Over several orbital periods, the accreted material eventually smeared out into a disk. Differential precession that occurred after the accretion event caused the disk to twist. Eventually, the disk settled into a fixed orientation with respect to the galaxy. The age of the disk is estimated to be around half a billion to a billion years.

It is located at a distance of circa 35 million light years from Earth, which, given its apparent dimensions, means that NGC 2835 is about 65,000 light years across. It was discovered by Wilhelm Tempel on April 13, 1884.[3] NGC 2835 is located only 18.5 degrees from the galactic plane.[4] NGC 2835 is seen nearly face-on. The galaxy features four or five spiral arms, visible in near infrared due to their population II stars.[5] The spiral arms have also numerous HII regions and stellar associations, the larger of which are 5 arcseconds across.[4] Although the galaxy is quite symmetric, the northern arms have HII regions that appear brighter than the southern ones. Also the southern arms appear less developed in their outer parts than the north ones.[6] The star formation rate in NGC 2835 is 0.4 M☉ per year and the total stellar mass of the galaxy is low, at 7.9x109 M☉.[7] In the centre of NGC 2835 lies a supermassive black hole whose mass is estimated to be 3-10 million (106.72±0.3) M☉, based on the spiral arm pitch angle.[8] https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1618242608907-CER9FCQTPBEM9DWGSHXY/NGC1055T.jpg Galaxies - NGC 1055 From Chile NGC 1055 From Chile Explanation via APOD: Big, beautiful spiral galaxy NGC 1055 is a dominant member of a small galaxy group a mere 60 million light-years away toward the aquatically intimidating constellation Cetus. Seen edge-on, the island universe spans over 100,000 light-years, a little larger than our own Milky Way galaxy. The colorful, spiky stars decorating this cosmic portrait of NGC 1055 are in the foreground, well within the Milky Way. But the telltale pinkish star forming regions are scattered through winding dust lanes along the distant galaxy's thin disk. With a smattering of even more distant background galaxies, the deep image also reveals a boxy halo that extends far above and below the central bluge and disk of NGC 1055. The halo itself is laced with faint, narrow structures, and could represent the mixed and spread out debris from a satellite galaxy disrupted by the larger spiral some 10 billion years ago.

First discovered by William Herschel in 1785, the galaxy has numerous star streams and plumes associated with it which are probably the result of a merger with another spiral galaxy about 1 billion years ago. It may take another billion years for this merger to settle down. It was this odd shape that led to its inclusion in Arp’s catalogue of peculiar galaxies. The support for the merger scenario comes from the fact that there are two star like objects near the core of NGC 7727, one of which may be the core of the merging galaxy and the other the main core of NGC 7727. NGC 7727 does not seem to have a large reservoir of hydrogen gas to form new stars so it is probably going to become an elliptical galaxy in the future. Images from GALEX, an ultraviolet satellite, show very little star formation going on at the current time in NGC 7727 compared to its neighbor NGC 7724.

Even our own galaxy practices galactic cannibalism, absorbing small galaxies that get too close and are captured by the Milky Way's gravity. In fact, the practice is common in the universe and illustrated by this striking pair of interacting galaxies from the banks of the southern constellation Eridanus (The River). Located over 50 million light years away, the large, distorted spiral NGC 1532 is seen locked in a gravitational struggle with dwarf galaxy NGC 1531, a struggle the smaller galaxy will eventually lose. Seen edge-on, spiral NGC 1532 spans about 100,000 light-years. Nicely detailed in this sharp image, the NGC 1532/1531 pair is thought to be similar to the well-studied system of face-on spiral and small companion known as M51. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1600828816317-SBR223L2F0QW3IQ3MQ45/NGC1512Thumb.jpg Galaxies - NGC 1512-New NGC 1512 NGC 1512 is a barred spiral galaxy approximately 38 million light-years away from Earth in the constellation Horologium.

On average, these barred spiral galaxies are supposed to be two billion years old, the bulge being the oldest and the youngest part being the arms of the galaxy and the outer ridge of the galaxy. One of the leading hypothesis of the arm formation supposes that the presence of density waves from the bulge caused the star formation to occur in a sort of spiral shape in the galaxy. NGC 5068 is about 6.8 million pc away from Earth and about 45,000 light years in diameter. In the spiral galaxy photo, we can see the bar in the center where a black hole resides. This bar is evidence that the galaxy has finished its formative years, and is starting to become fully mature. You can also see the spiral arms surrounding the center bar, representing the younger stars in the galaxy. There is a high rate of star formation in this arms, making the arms clear and bright. This spiral galaxy can be compared to the Milky Way (the galaxy in which our solar system resides), which also has a barred spiral structure, with a supermassive black hole in the bulge.

That huge swarm of over 1000 galaxies that straddles the Coma Berenices-Virgo region. However not so well known is that there is another equally large cluster in Coma Berenices known as The Coma Cluster or Abell Galaxy Cluster 1656. The main reason that this galaxy cluster is not so well known is that the cluster is nearly 10 times further away than the Virgo cluster, at a distance of over 400 million light years. This means that most of the members of the cluster are small and faint. The brightest members are the giant elliptical galaxy NGC 4889 and 4874.

Found about 40 million light-years from Earth toward the constellation of Leo, NGC 3521 has a somewhat obvious nickname: the Bubble Galaxy. When viewed from afar, it appears to be completely encased in a large, but faint, bubble. What looks like a second bubble also surrounds its nucleus. Astronomers believe the shell is an artifact of galaxy mergers.. namely when NGC 3521 and several smaller galaxies collided. In the immediate aftermath, a bunch of gas, dust and rogue stars were strewn all throughout space—eventually coalescing back into a familiar form (features such as halos, stellar streams and tidal tails are common in events like this). The merger also led to the formation of many star clusters, which are pink-tinged. Those with a blue-white hue are high-mass, bright and incredibly hot. They will only live for a few hundred million years before they explode as supernovae—reseeding space with raw materials. The first image is with No Ha and the image below that has some HA added.

Located about 50 million light-years away, the galaxy's two spiral arms extending from a pronounced central bar give it a hook-shaped appearance. This deep color image also shows the arms' obscuring dust lanes, young blue star clusters and reddish star forming regions surrounding a core of yellowish light from an older population of stars. But the star forming regions seem more concentrated along the drawn-out (right side) spiral arm. The distorted structure is likely the result of an ancient close encounter with the smaller galaxy seen near the top left of this field of view. The two interacting galaxies are separated by about 150,000 light-years at the estimated distance of NGC 2442. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1583505261168-KVKUN2OYQHX1ZSOI1EWB/NGC-4038-4039Thumb.jpg Galaxies - The Antennae Galaxy Explanation: Some 60 million light-years away in the southerly constellation Corvus, two large galaxies are colliding. Stars in the two galaxies, cataloged as NGC 4038 and NGC 4039, very rarely collide in the course of the ponderous cataclysm that lasts for hundreds of millions of years. But the galaxies' large clouds of molecular gas and dust often do, triggering furious episodes of star formation near the center of the cosmic wreckage. Spanning over 500 thousand light-years, this stunning view also reveals new star clusters and matter flung far from the scene of the accident by gravitational tidal forces. The remarkable mosaicked image was constructed using data from the ground-based Subaru telescope to bring out large-scale and faint tidal streams, and Hubble Space Telescope data of extreme detail in the bright cores. The suggestive visual appearance of the extended arcing structures gives the galaxy pair its popular name - The Antennae. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1577975293531-QNXU7C5P9QL1UY6ALW3A/CropNGC908.jpg Galaxies - NGC 908 NGC 908 is an unbarred spiral galaxy in the constellation Cetus.

NGC 5291 and the likely interloper, also known as the "Seashell" galaxy, are captured near the center of this spectacular scene. The sharp, ground-based telescopic image looks toward the galaxy cluster Abell 3574 in the southern constellation Centaurus. Stretched along the 100,000 light-year long tidal tails, are clumps resembling dwarf galaxies, but lacking old stars, apparently dominated by young stars and active star forming regions. Found to be unusually rich in elements heavier than hydrogen and helium, the dwarf galaxies were likely born in intergalactic space, recycling the enriched debris from NGC 5291 itself.

It was discovered by German-British astronomer William Herschel on 20 October 1784. It is dominated by millions of bright stars and dark dust, in spiral arms rotating about the center. Open clusters containing bright blue stars are sprinkled along these spiral arms, with dark lanes of dense interstellar dust between. Less visible are dim normal stars and interstellar gas, producing such high mass that they dominate the dynamics of the inner galaxy. Not visible is matter of unknown form called dark matter, needed to explain the motions of the visible material in the outer galaxy. The galaxy is approximately 200,000 light-years across, in between the sizes of the Andromeda Galaxy and our home galaxy, the Milky Way. NGC 1232 and its satellite are part of the Eridanus cluster of galaxies, along with NGC 1300. NGC 1232A is a satellite galaxy of NGC 1232. It is thought to be the cause of unusual bending in the spiral arms. In 1988, NGC 1232A was estimated to be 68 million light-years away while NGC 1232 was estimated to be 65 million light-years away.

Still, the tantalizing island universe is a clearly a telescopic treasure in southern skies. It shares a bright core, clumpy dust lanes, and loosely wrapped spiral arms with spiky foreground stars of the Milky Way and the more diminutive galaxy NGC 131 in this sharp cosmic vista. From a distance of about 60 million light-years, NGC 134 is seen tilted nearly edge-on. It spans some 150,000 light-years, making it even larger than our own Milky Way galaxy. NGC 134's warped disk and faint extensions give the appearance of past gravitational interactions with neighboring galaxies. Like the much closer and brighter Sculptor galaxy NGC 253, tendrils of dust appear to rise from a galactic disk sprinkled with blue star clusters and pinkish star forming regions. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1564407389818-2TW5FVGCXVPCIRW4GXRK/Thumb.jpg Galaxies - NGC 4273 NGC 4273 and NGC 4281 are members of a small sub-group of the Virgo Cluster. In the image below, NGC 4273 is the face-on spiral near the centre, while NGC 4281 is the larger elliptical galaxy to the upper left. The eastern spiral arm of NGC appears to be distorted a little, probably by the gravitational pull of NGC 4277 just to its left. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1564238443133-16VSIIQ53B6TELB4QGW0/Abell2151Thumb.jpg Galaxies - Abell 2151 Abell 2151 Galaxy Cluster Copyright Mark Hanson Description by Sakib Rasool Abell 2151 is a mighty cluster of galaxies with a surplus of beautiful interacting galaxies. Interestingly its distribution is quite chaotic and lacks the typical central elliptical galaxy that is a common feature of most galaxy clusters. However the brightest galaxy is the elliptical NGC 6041. In the grand scheme of the universe, Abell 2151 (also known as the Hercules Galaxy Cluster) is located 500 million light years away and covers an area of 6 million light years with about 200 galaxies. It is part of the Hercules Supercluster, which is part of an even larger extragalactic structure simply known as the Great Wall. This has a huge span of 500 million light years and was discovered in the 1980's by Margaret Geller and John Huchra. One aspect of Abell 2151 that is immediately apparent is the abundance of peculiar and interacting galaxies. In fact, there are so many that a record number of four were included in the Arp Atlas, the most for any galaxy cluster. These include Arp 71 (NGC 6045), Arp 122 (NGC 6040), Arp 172 (IC 1178/81) and Arp 272 (NGC 6050/IC 1179). NGC 6040 is an interesting pair of galaxies interacting with each other and in the process of being absorbed into the galaxy cluster, its neutral hydrogen gas has been removed through ram pressure stripping, a phenomenon that has been observed in other galaxy clusters. NGC 6050 and IC 1179 represent a titanic collision between two behemoths that have been observed with the Hubble Space Telescope, which appears to show a third member in this system. Arguably the most distinguished member of Abell 2151 is IC 1182, a strange chaotic wreck of a galaxy that was somehow overlooked by Halton Arp. Although it is tempting to perceive the elongated blue structure as a jet launched from its core, it is in fact a tidal tail with a weaker second one near the opposing side. Another famous example of tidal tails being misconstrued as jets are the ones associated with the southern galaxy NGC 1097. In IC 1182, the longer tidal tail has a length of 205,000 light years while the smaller one is 88,000 light years long. It is very llkely its unique morphology is the result of an ongoing merger between two galaxies. Another interesting conclusion drawn from professional studies is that some of the blue knots in the large tidal tail might be in the process of forming tidal dwarf galaxies!

Consisting of chaotic and disordered structure, its appearance immediately hints at its turbulent history. A characteristic it has in common with M82 are multiple spidery tendrils of ionized hydrogen gas emanating outwards from its core. These were first discovered in 1974. Classed as a starburst dwarf galaxy, NGC 3077 is relatively nearby at 12 million light years. A series of tidally disrupted structures with striking blue stars is debris scattered from previous gravitational encounters with the other trio members, most notably M81. This structure has been nicknamed the "Garland" by professional astronomers and was first detected in photographic plates in the 1980's. Signatures of star formation triggered by tidal interactions are present as the many HII regions interspersed within its structure and at least 36 separate HII regions have been catalogued. Another unusual aspect of this perturbed galaxy is the subtle blue core, which is surrounded by a disk consisting of an older stellar population. Normally it is the other way round, spiral galaxies consist of a golden core with blue spiral arms. The strange distribution of stellar matter is an indicator of a massive starburst of new stars being formed near the core due to the raw material of star formation being centrally concentrated at the nucleus. Optical images such as this one don't always show the full picture of the morphology and kinematics of galaxies and other instruments are utilised to detect different parts that belong to other areas of the electromagnetic spectrum. Observations with radio telescopes are able to map the distribution of neutral hydrogen gas (HI), which is invisible optically. Witin the past few decades, the HI gas content of the M81 trio has been studied in superb detail and consists of many streamers and bridges connecting M81 and NGC 3077 together. A huge HI tail is also associated with NGC 3077 and contains more neutral gas than the core.

It is receding from us at approximately 1,362 kilometers per second. The name “Arp 185” derives from being included in Arp’s Atlas of Peculiar Galaxies, a catalog of 338 peculiar galaxies, drawn up by Halton Arp in the years from 1962 through 1967 and published by the California Institute of Technology. Arp 185 is on the list of the “100 Brightest Arps”, which was sorted and created by Jim Shields. NGC 6217 has moderately-wound spiral arms, and a prominent, long and well-defined bar running across a spherical, very bright active nucleus where probably a supermassive black hole resides. Throughout the galaxy we can see narrow, filamentary dark dust lanes, blue clusters full of hot, young stars, and dozens of pink star-forming emission nebulae. It has been characterized as a starburst galaxy, which means it is undergoing a high rate of star formation compared to a typical galaxy. It is dominated by stars less than 10 million years old, giving the galaxy a blue hue. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1557335021550-S050LWBUTV627AZ0THJM/5557Thumb.jpg Galaxies - NGC 5557 The cosmic scene depicted in this deep astrophoto is the region towards the elliptical galaxy NGC 5557 in the constellation of Bootes. For a long time, ellipticals were regarded as the placid endpoint of galactic evolution. However this view has been challenged by the discovery of tidal shells and plumes around a large number of elliptical galaxies in the past few decades. These extended structures convey a rich kinematical history involving mergers with other galaxies, a process commonly associated with interacting spiral galaxies. Located at a distance of 126 million light years, NGC 5557 is enveloped by multiple shells and extremely faint tidal plumes that extend for 1.2 million light years with less than the full extent included in the field of view of this image. Professional studies have surmised the material constituting the tidal structures likely originates in a major merger with a large galaxy whose original structure has been disrupted beyond recognition. In the chaos of all this tidal disruption, the formation of so-called tidal dwarf galaxies can be triggered. At least three tidal dwarf galaxies have been discovered associated with NGC 5557 but only one is included in the field of view of this image, it is the fuzzy detached object located at the northern tip of the curved tidal stream to the south. Their discovery represent the oldest examples of their kind in the nearby universe and have an estimated age of 2-4 billion years. Complementing this hive of activity is the interacting galaxy pair NGC 5544-5, which are also collectively known as Arp 199. NGC 5544 is the face on galaxy while NGC 5545 is the blue spiral that overlaps it. They also have a similar distance of 140 million light years. Interestingly, all three galaxies were discovered on the same night in 1785 by William Herschel. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1556660265533-R322BBJTGEDAHQTNSFXN/M95Thumb.jpg Galaxies - Messier 95 Messier 95, also known as M95 or NGC 3351, is a barred spiral galaxy located about 33 million light-years away in the zodiac constellation Leo. It was discovered by Pierre Méchain in 1781, and catalogued by fellow French astronomer Charles Messier four days later. On 16 March 2012, a supernova was discovered in M95. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1556650561392-X6O42QV60Y614DLLZWRR/M87Thumb.jpg Galaxies - M87- Elliptical Galaxy with Jet M87- Elliptical Galaxy with Jet Explanation Via AOPD: In spiral galaxies, majestic winding arms of young stars, gas, and dust rotate in a flat disk around a bulging galactic nucleus. But elliptical galaxies seem to be simpler. Lacking gas and dust to form new stars, their randomly swarming older stars, give them an ellipsoidal (egg-like) shape. Still, elliptical galaxies can be very large. Centered in this telescopic view and over 120,000 light-years in diameter, larger than our own Milky Way, elliptical galaxy M87 (NGC 4486) is the dominant galaxy of the Virgo Galaxy Cluster. Some 50 million light-years away, M87 is likely home to a supermassive black hole responsible for a high-energy jet of particles emerging from the giant galaxy's central region.

The result of a merger between an elliptical galaxy and a spiral galaxy, it displays a wide variety of kinematical features. It is the closest known active galaxy at 11 million light years. The remnant of the original spiral galaxy is represented by its central dust lane highlighted along its edges with the signatures of star formation such as blue star clusters and red emission nebulae. Many cosmic collisions between galaxies trigger a massive starburst of starforming activity as the neutral gas reservoir is increased and pressure and gravity compress gas clouds into active sites of starbirth. The original collision has also strewn small dust globules across the disk of the galaxy. This intergalactic encounter between two galaxies has also deformed the structure of the original elliptical galaxy and faint tidal shells envelop the galaxy. They were originally discovered by the astronomers David Malin and David Carter in the 1970's through special photographic amplification techniques. Their discovery prompted the publication of a catalogue of shell elliptical galaxies in 1983 and there are a few hundred known to belong to this category. Images with a wider field of view than this show multiple interlocking shells that extend even further. The origin of these shells are minor mergers with multiple smaller galaxies and are created by the disruption of orbits of captured stars. NGC 5128 is also known as Centaurus A and this particular naming scheme denotes the first radio source to be discovered in a particular constellation. As it has been detected by astronomers in observations made with radio telescopes, it belongs to another category of radio galaxies. Radio galaxies are so-called as they radiate more emission in radio than in optical. They are a type of active galactic nucleus (usually abbreviated to AGN). As the name suggests, galaxies that feature an AGN have an energetic nuclear region centered around a supermassive black hole. Although not immediately apparent, the AGN activity in Centaurus A is represented optically by a long filamentary jet, which can be seen north of the core. The jet arises from an outflow of gas that has built up in the accretion disk surrounding the supermassive black hole and its narrow appearance is the product of interacting magnetic fields associated with the black hole. This jet appears as an impressive bipolar outflow in x-ray and radio images.

M91 is about 63 million light-years away from the earth. It was the last of a group of eight nebulae discovered by Charles Messier in 1781. Originally M91 was a missing Messier object in the catalogue as the result of a bookkeeping mistake by Messier. It was not until 1969 that amateur astronomer William C. Williams[3] https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1551406244007-ZGX8O05VIX24IBM0PVEO/NGC+3642APODCrop.jpg Galaxies - NGC 3642 NGC 3642 is a spiral galaxy in constellation Ursa Major. The galaxy has a low-ionization nuclear emission-line region. It is located at a distance of circa 30 million light years from Earth, which, given its apparent dimensions, means that NGC 3642 is about 50,000 light years across. The galaxy is characterised by an outer pseudoring, which was probably formed after the accretion of gas rich dwarf galaxy.[2] Contents 1 Structure 2 Nearby galaxies 3 References 4 External links Structure NGC 3642 is a spiral galaxy without bar.[2] In the nucleus there is a supermassive black hole with estimated mass 26-31 millions M⊙, based on the intrinsic velocity dispersion as measured by the Hubble Space Telescope,[3] or 15 millions M⊙, based on the bulge luminosities in near-infrared Ks-band.[4] Around the nucleus, an one-armed spiral forms a ring, and it is possible that it leads material towards the nucleus. The nucleus surrounded by an inner flocculent spiral. The outer part of the spiral forms a pseudoring that extents for about half a circle. The outer part of the spiral is warped, while its main part features an ordinary differentially rotating disk. The HI gas is also warped and extents more in the western side.[2] https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1547502847651-62ZWZJT0YT2M8S24G51G/NGC2655WebThumb.jpg Galaxies - NGC 2655 - Arp 225 "Floating in the serenity of the universe like a cosmic ammonite shell, NGC 2655 is an impressive example of a lenticular galaxy. Located 60 million light years away towards the constellation of Camelopardalis, its series of outer shell structures and faint tidal loops are nicely complemented by internal dust lanes near its core. Its panoply of morphological kinematics are indicative of a merger between two galaxies in the past, an intergalactic event that is now known to be a common feature of the evolution of galaxies. Other signatures of a past merger that aren't apparent to the eye are vast clouds of neutral hydrogen surrounding the galaxy that were uncovered in observations made using radio telescopes by professional astronomers. The unusual appearance of NGC 2655 brought it to the attention of the famous astronomer Halton Arp who added it to his atlas of peculiar galaxies under Arp 225. Another distinction is that the core is very luminous, which means that NGC 2655 belongs to the category of active galaxies known as Seyfert galaxies, which were named after the astronomer Karl Seyfert. The luminosity of Seyfert galaxies is thought to derive from a transfer of matter onto an accretion disk around a supermassive black hole. NGC 2655 is the brightest member of a small group of galaxies that also includes NGC 2715 (not visible in image). The diameter of NGC 2655 is approximately 200,000 light years but the envelope of neutral hydrogen gas discovered in the 1980's is about 500,000 light years." https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1547143580895-1U4P0SL99O1W2MA17FQI/NGC2782NewWebT.jpg Galaxies - NGC 2782 aken from DGRO Rancho Hidalgo Animas, New Mexico 14.5" RCOS F8, Apogee U16M High Cooling Luminance 360, Red 180, Green 140, Blue 180 Calibrated,combined in CCD Stack all other processing done using PS5. The starburst galaxy NGC 2782 lies about 110 million light years away toward the Lynx constellation. This shows the result when two galaxies of unequal mass collided about 200 million years ago. Their gravitational pull ripped out two tails of debris with very different properties. The optically bright eastern tail has some neutral hydrogen gas and molecular gas at the base of the tail, and an optically bright, but gas-poor concentration at the end of the tail. The optically faint western tail is rich in neutral hydrogen gas, but has no molecular gas, yet astronomers have recently found blue star clusters younger than 100 million years along both tails, indicating that those stars formed within both tails after the galaxy collision occurred. Current star-formation theory suggests that star clusters are formed from the collapse of giant molecular gas clouds, but if this were the case, astronomers would expect to see remnants of the molecular gas which helped give birth to the stars in both of the tails of NGC 2782. Finding unexpected young star clusters in the western tail could help explain why stars form in other places where there is little molecular gas, like the outer edges of the Milky Way galaxy or in the debris of other galaxy collisions. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1546869623065-OHX8YAIZ66U0ASUQ2U31/NGC4214New+WebThumb.jpg Galaxies - NGC 4214 Dwarf Galaxy Taken from DGRO Rancho Hidalgo Animas, New Mexico 14.5" RCOS F8, Apogee U16M High Cooling Luminance 390, Red 140, Green 140, Blue 140, Calibrated,combined in CCD Stack all other processing done using PS5. The dwarf galaxy NGC 4214 is ablaze with young stars and gas clouds. Located around 10 million light-years away in the constellation of Canes Venatici (The Hunting Dogs), the galaxy's close proximity, combined with the wide variety of evolutionary stages among the stars, make it an ideal laboratory to research the triggers of star formation and evolution. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1545961031226-HC92C2EHIA0SOTHZ4VLJ/NGC918-WebSmall.jpg Galaxies - NGC 918 https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1542672917276-9X2WMQSNKCFH21EEKLSU/NGC2146Apod-2Crop.jpg Galaxies - NGC 2146 NGC 2146 is a barred spiral galaxy in the constellation Camelopardalis. The most distinctive feature is the dusty spiral arm that has looped in front of the galaxy's core as seen from our perspective. The forces required to pull this structure out of its natural shape and twist it up to 45 degrees are colossal. The most likely explanation is that a neighboring galaxy is gravitationally distorting the orbits of many of NGC 2146's stars. It is probable that we are currently witnessing the end stages of a process that has been occurring for tens of millions of years. NCG 2146 is undergoing intense bouts of star formation, to such an extent that it is referred to as a starburst galaxy. This is a common state for barred spirals, but the extra gravitational disruption that NGC 2146 is enduring no doubt exacerbates the situation, compressing hydrogen-rich nebulas and triggering stellar birth. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1542217569383-B5MVKC15PJHMXQBCIM4N/Arp284FinalApodsmall.jpg Galaxies - Arp 284 Three Giant Leaps Image Credit & Copyright: Mark Hanson Description by Brian Ottum Three different objects in this image demonstrate the immensity of the known universe. The bright star is 16 Piscium, located just 100 light-years from Earth, within our home Milky Way galaxy. The pair of interacting galaxies (Arp 284) are a thousand times further away than the bright star, 100 million light-years from Earth. Finally, the tiny blue quasar's (B2333+019A) & (B2334+019A) are a hundred times further away than the pair of galaxies at 10 and 11 billion light-years from Earth. The 3 different objects demonstrate the immense power of gravity. 1. The bright star creates light through gravity-generated fusion. 2. Gravity is pulling the pair of galaxies Arp 284 also known as (NGC 7714 and NGC 7715) toward each other, gradually tearing them apart in the process. 3. Finally, 2 separate super massive black holes have so much gravitational pull that it is vacuuming up its host galaxy, allowing only an extremely bright jet of light (the 2 quasars) to escape and be blasted towards Earth. We are seeing light that started its journey when the universe was relatively young at just 3 billion years old. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1540215046137-KCCLUV0MS74GBHEETB4J/NGC6140Thumb.jpg Galaxies - NGC 6140 https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1530231184218-9FUN8VMV9SVRFS2HQE9A/NGC5907+APOD-2Thumb.jpg Galaxies - NGC 5907 "Slicing through the dark cold depths of space towards the constellation of Draco, the knife edge disk of the Splinter Galaxy is depicted in this impressively deep image. Otherwise catalogued as NGC 5907, rusty coloured dust lanes near the centre compete with a stainless steel blue outer edge composed of younger stars. This part also features a lower amount of dust obscuration. The beauty of long exposure images taken with remote observatories under dark skies elucidate incredibly low surface brightness tidal streams. Originally discovered by a team of professional astronomers in 1998, it wasn't until the pioneering work of David Martinez-Delgado and his crack squad of amateur astro-detectives (of which a certain Mark Hanson is a member) that it was conclusively confirmed as a true definite structure around the galaxy. Like the myriad of clues left behind at a crime scene, professional astronomers can reconstruct the history of an intergalactic murder mystery but this time involving a huge galaxy like NGC 5907 and a smaller companion galaxy that is disrupted and ultimately destroyed. The tidal stream that is recovered in deep optical images could be thought of as the ghost of the previous satellite galaxy. This structure is the product of the effect of the gravity of the larger galaxy and the decay of the orbit of the smaller galaxy and it leaves behind a trail of stars ripped from it that trace its disrupted orbit around the larger galaxy. This tidal stream has an estimated size of 150,000 light years." https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1527720376046-EOTTZLPLIZA6O0Z4NQ8U/M86LRGBHA.jpg Galaxies - M 86 Taken from SWO "This stunning image depicts the dynamic and dramatic centre of the Virgo Cluster. At a distance of approximately 50 million light years, it is the closest galaxy cluster to Earth and is dominated by the large elliptical galaxies M86 and M84. However what makes this image special is the addition of 30 hours of narrowband Ha exposures that illuminate blazing filaments of gas that emit in the hydrogen alpha line! These are the product of a collision between M86 and the blue peculiar deformed spiral galaxy NGC 4438. With a staggering length of 400,000 light years, they signify the tempestuous relationship between interacting galaxies at the heart of galaxy clusters. NGC 4438 is also interacting with its elliptical companion NGC 4435 and both are collectively catalogued as Arp 120 in the Arp Atlas of peculiar galaxies. Another sign of peculiarity is a rarely seen tidal tail extending from NGC 4435. Another point of interest is a swarm of low surface brightness dwarf galaxies enveloping M86. These are currently being analysed by professional astronomers to help gain insight into the nature of the elusive dark matter purported to exist within the framework of cosmological models." https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1527717682505-TJ3VK4O3JGR7BD1JS6HR/NGC+5566Apod-2FullCrop.jpg Galaxies - NGC 5566- Arp 286 From SWO Explanation Via APOD: A remarkable telescopic composition in yellow and blue, this scene features a trio of interacting galaxies almost 90 million light-years away, toward the constellation Virgo. On the left, two, spiky, foreground Milky Way stars echo the trio galaxy hues, a reminder that stars in our own galaxy are like those in the distant island universes. Predominately yellow, with sweeping spiral arms and dust lanes, NGC 5566 is enormous, about 150,000 light-years across. Just below it lies small, blue NGC 5569. Near center, the third galaxy, NGC 5560, is multicolored and apparently stretched and distorted by its interaction with NGC 5566. The galaxy trio is also included in Halton Arp's 1966 Atlas of Peculiar Galaxies as Arp 286. Of course, such cosmic interactions are now appreciated as a common part of the evolution of galaxies. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1525988819422-4AD6XRTHAVVIJNYLQ5T3/NGC+4449Apodsmall.jpg Galaxies - NGC 4449 in Canes Venatici "Belonging to the class of Magellanic type irregular galaxy, NGC 4449 is a small but lovely cosmic denizen of the constellation Canes Venatici. It is very close (in astronomical terms) at 12.5 million light years. Blazing across its structure is a starburst of young blue stars and active red nebulae forming new stars at a (fast) and furious pace! Detailed analysis of the starburst has determined that it started 500 million years ago. For many years, it was hypothesized that the starburst observed in NGC 4449 was triggered by an interaction with another galaxy. Enter astronomer extraordinaire David Martinez-Delgado and his pro-am collaboration project to document tidal streams in nearby galaxies. His tidal stream survey has uncovered previously unknown tidal streams in many galaxies. Utilizing a group of amateur astrophotographers led by Jay GaBany with a worldwide network of telescopes and remote observatories, it has been possible to obtain very long exposures that would not normally be possible with professional observatories due to limitations imposed by time allocation constraints. The group of amateur astrophotographers includes many famous people such as Ken Crawford, Adam Block, Fabian Neyer, a certain Mark Hanson and many others. Deep images taken by the tidal stream survey group uncovered an extremely faint tidal stream, which is the remnant of a former dwarf companion. Special image processing techniques combined with very long exposures are able to reveal very faint features that would not normally be visible. This stream can be seen as the ghostly elongated tidal feature to the south of NGC 4449. It was first discovered in 2007 by Igor Karachentsev and followed up for a definitive detection by the tidal stream survey team. The stream has a size of approximately 23,000 x 5000 light years. The accretion of smaller galaxies is a major contributing factor to galaxy assembly and is a major topic of research in astrophysics. Revealing the dim past of galaxies can help gain insight to their future and address related topics such as dark matter distribution." https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1525970482463-8GRQBU2GGMT6IJFNNRJD/M49Aopdsmall.jpg Galaxies - Messier 49 in Virgo Messier 49 in Virgo "M49 is a large elliptical galaxy with a tenuous diffuse tidal shell structure. With a magnitude of 9, it is easily observable by visual observers. It is located 56 million light years away and forms a magnificent if unappreciated galaxy group. One of the many members of the Virgo Cluster, M49 is a giant elliptical galaxy with a size of 157,000 light years. It is home to an estimated 6000 globular clusters, which seem to be found in greater abundance in elliptical galaxies. M49 is interacting with the blue dwarf galaxy UGC 7636 below and to the left of it. This is visually illustrated by a diffuse tidal plume to the north of it stretching towards the direction of M49. The tidal plume has a size of approximately 100,000 x 20,000 light years. M49 was also included by the late Halton Arp in his Arp Atlas of Peculiar Galaxies as Arp 134."

It is 60 million light-years away, and it is estimated to be 125,000 light-years across. M85 is extremely poor in neutral hydrogen and has a very complex outer structure with shells and ripples that are thought to have been caused by a merger with another galaxy that took place between 4 and 7 billion years ago.

Both galaxies were included by Charles Messier in his 18th century collection of objects that are not comets. The one on the right is M89 and the one on the left is M90, both are between 50 and 60 million light years away along with the small companion of M90, IC 3583. This image perfectly illustrates the influence of environment on galaxy evolution. M90 was considered a placid serene galaxy with very little activity and a low star formation rate. Recent studies by professional astronomers show it to be experiencing ram pressure stripping, a phenomenon that is known to affect many galaxies in the Virgo Cluster and other galaxy clusters. Galaxy cluster environments contain lots of hot gas visible in x-rays known as the intracluster medium (ICM). The movement of a galaxy through the ICM creates a "wind" that exerts pressure that strips gas away from the galaxy due to it being gravitationally bound with less strength than the surrounding forces. As M90 has fallen through the Virgo Cluster toward its center, cold neutral gas has been stripped away from it thereby quenching any future star formation. The effects of ram pressure stripping on M90 are dramatically illustrated with low surface brightness tails of ionized gas revealed with deep narrowband Ha exposures, which were discovered in 2016. They have a length of 472,000 light years and currently it is unclear what the ionizing mechanism is. M89 is an unusual elliptical galaxy with a series of tidal shells and plumes revealed with long exposures. M89 was one of the first elliptical galaxies where a series of outer shells was identified in 1979 by the esteemed astronomer David Malin. This discovery was made possible through innovative techniques developed by David Malin involving enhancement and amplification of faint features on photographic plates and led to the publication of a catalogue of shell elliptical galaxies. The linear feature was first reported in 1979 to be a jet from the galaxy core but is actually a well placed tidal stream structure. The origin of the shells is not conclusive but the explanation most commonly invoked for this type of galaxy are multiple mergers with previous companion galaxies. M89 is also experiencing gas stripping but this is only observable in x-rays. Images taken with the Chandra telescope show a tail of gas, these features are a result of it also falling into the Virgo Cluster." https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1519070789410-97IOGP14GRN7N7VY03OT/NGC4410Group.jpg Galaxies - NGC 4410 Group SWO in New Mexico This rarely photographed region of Virgo contains a vast variety of galaxies. Near the centre is a relatively serene spiral galaxy pair that is collectively known as NGC 4411. Much more striking is the connected system of interacting galaxies to the north, which are collectively catalogued as NGC 4410. Much further in the distance are a few galaxy clusters, most notably Abell 1541 near the bottom left corner. Less apparent and more pervasive are hundreds of fuzzy dots in the background, these are all distant galaxies billions of light years away!   NGC 4410 is a group of interacting galaxies connected by tidal bridges and in addition to this also exhibits tidal tails and plumes. The whole menagerie of morphological features is due to the effect of gravitational interaction between the various galaxies due to their proximity to each other. This group in total contains 12 members and is located 316 million light years away and in the future is likely to merge into a single elliptical galaxy. Interestingly, NGC 4411 is only a visual pair with the galaxy on the left being 91 million light years away while the one on the right is closer with a distance of 49 million light years.

In fact, ringed by blue-tinted star forming regions and faintly visible spiral arms, the yolk-yellow center of this face-on spiral galaxy, NGC 7742, is about 3,000 light-years across. About 72 million light-years away in the constellation Pegasus, NGC 7742 is known to be a Seyfert galaxy - a type of active spiral galaxy with a center or nucleus which is very bright at visible wavelengths. Across the spectrum, the tremendous brightness of Seyferts can change over periods of just days to months and galaxies like NGC 7742 are suspected of harboring massive black holes at their cores. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1509644818035-JERWU1213J94XQSRTQW1/Abell426-NGC1275ApodCrop.jpg Galaxies - NGC 1275 Abell 426 NGC 1275 (also known as Perseus A or Caldwell 24) The Perseus Cluster (Abell 426), located 237 million light-years away in the constellation of Perseus, contains thousands of galaxies immersed in a vast cloud of multi-million degree gas.

It was the first galaxy to be classified as a spiral galaxy. Recently it was estimated to be 23 ± 4 million light-years from the Milky Way,but different methods yield distances between 15 and 35 million light-years. Messier 51 is one of the best known galaxies in the sky. The galaxy and its companion, NGC 5195, are easily observed by amateur astronomers, and the two galaxies may even be seen with binoculars. The Whirlpool Galaxy is also a popular target for professional astronomers, who study it to further understand galaxy structure (particularly structure associated with the spiral arms) and galaxy interactions.

It was the first galaxy to be classified as a spiral galaxy. Recently it was estimated to be 23 ± 4 million light-years from the Milky Way,but different methods yield distances between 15 and 35 million light-years. Messier 51 is one of the best known galaxies in the sky. The galaxy and its companion, NGC 5195, are easily observed by amateur astronomers, and the two galaxies may even be seen with binoculars. The Whirlpool Galaxy is also a popular target for professional astronomers, who study it to further understand galaxy structure (particularly structure associated with the spiral arms) and galaxy interactions.

The galaxy is unusual in that it contains a ring but no bar. Typically, bars are needed to produce a ring structure. The bars' gravitational forces move gas to the ends of the bars, where it forms into the rings seen in many barred spiral galaxies. In this galaxy, however, no bar is present, so this mechanism cannot be used to explain the formation of the ring. O. K. Sil'chenko and A. V. Moiseev proposed that the ring was formed partly as the result of a merger event in which a smaller gas-rich dwarf galaxy collided with NGC 7742. As evidence for this, they point to the unusually bright central region, the presence of highly inclined central gas disk, and the presence of gas that is counterrotating (or rotating in the opposite direction) with respect to the stars. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491435282418-FOU9F1VB67EHT0UQIKSP/NGC1313DoneNew.jpg Galaxies - NGC 1313 (SSRO Cito, Chile) https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491435226248-R31D113050S155RE6PMO/IC2574APY2016MarkHanson.jpg Galaxies - IC 2574 (Stellar Winds Observator-DSNM) https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491951422928-UQQ4UR7OYXTN9LGYKEVJ/M89-Finished4-5-17-2.jpg Galaxies - M89 in new Light(Stellar Winds Observatory, DSNM) M89 with tidal tail and extended Halos https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491435291469-9N72TF8PBHHY37K4TNRX/NGC247New.jpg Galaxies - NGC 247 (SSRO Cito, Chile) https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491951001896-BJ13FFHHKBN6DEJ5K440/NGC7734.jpg Galaxies - NGC 7377 From SSRO Cito, Chile https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491433149303-Q9VJBW0WVYJ5ICV7B12M/NGC3166web.jpg Galaxies - NGC 3166 & 3169 (Stellar Winds Observatory -DSNM) https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491435349049-ODAQB53XHCKIGQ5MAQ91/The+Eyes+Astronomymag.jpg Galaxies - The Eyes Galaxies /NGC 4435-4438 (SWO at Rancho Hidalgo)) Arp 120, The Eyes Galaxies, NGC 4435 and NGC 4438 https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491435354928-FS1D1ROMSMIJ8LJO414W/NGC6744Done.jpg Galaxies - NGC 6744 (SSRO Cito, Chile) https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491433157610-2PX6WKPSJP4MEV902PYI/NGC7497Done.jpg Galaxies - NGC 7497 (DGRO-Rancho Hidalgo) https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491435232479-4XW03P7CQEY89IZDW4KV/NGC+300+Finished.jpg Galaxies - NGC 300 (SSRO Cito, Chile) https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491435202798-CSDOPXZPP4H421JKEW0Y/IC10AMag.jpg Galaxies - IC 10 (SRO-California) https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491432702585-EE9LQOCOSIAAZ713Z9LQ/Finished106-2.jpg Galaxies - M 106-NGC4258 (DGRO-Rancho Hidalgo) https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491433019016-XYP7E2X0IXERS5X8H4RL/Dearlick+Final.jpg Galaxies - NGC 7331-Deer Lick Group (DGRO-Rancho Hidalgo) https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1492813143006-64ZOA851QAX38T95E77G/NGC+4656.jpg Galaxies - NGC 4656 (DGRO-Rancho Hidlago) https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491433162874-3BQP665PHRD28JAUPTS7/WebNGC4656.jpg Galaxies - NGC 4656 & 4631 (DGRO- Rancho Hidalgo) https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491433096771-O7YPP6JC7VV1TA8QTR3G/M82.jpg Galaxies - M82 the Cigar Galaxy (DGRO-Rancho Hidalgo) https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491433088461-3LPTOLKKOFMYP6WV3R4X/M81_82Fullweb.jpg Galaxies - M81 and M82 (DGRO-Rancho Hidalgo) https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491433022185-390GNZCXIKQS96BPHWKK/IP+5850.jpg Galaxies - NGC 5850 (Lightbuckets-Rodeo New Mexico) https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491433034195-040ITL9IV7DPWXR4BZQW/M33MarkProc75.jpg Galaxies - M33 (DGRO-Rancho Hidalgo) https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491433057562-IYDHAN4GJM1BV0FGWRQ6/M51Done70.jpg Galaxies - M51 From 14.5RC Rancho Hidalgo https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491433138217-LH6VEJO41H30Q9I3MS0O/NGC3628+APOD.jpg Galaxies - NGC 3628 https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1492800476698-THNI4IUS2ND6ESWF0K85/NGC3628-REProNEW.jpg Galaxies - NGC 3628 https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491433171546-IEV8UKZD8VIUZZR82YS1/NGC6822Final.jpg Galaxies - NGC 6822 (DGRO-Rancho Hidalgo) https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1492800546573-ZEOXIH7G6KY3F1H3J5BH/NGC3521-Web.jpg Galaxies - NGC 3521 (DGRO Rancho Hidalgo) NGC 3521 NGC 3521 With deep luminance from 14.5"RCOS from Rancho Hidalgo, NM https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1492813153108-JG1F3M04IAZDDTOUQF10/NGC891Web-Recovered.jpg Galaxies - NGC 891 (DGRO- Rancho Hidalgo) NGC 891 Taken from DGRO Rancho Hidalgo Animas, New Mexico 14.5" RCOS F8, Apogee U16M High Cooling Luminance 420, Red 165, Green 165, Blue 165 Calibrated,combined in CCD Stack all other processing done using PS5. This spiral galaxy spans about 100 thousand light-years and is seen almost exactly edge-on from our perspective. In fact, about 30 million light-years distant in the constellation Andromeda, NGC 891 looks a lot like our Milky Way. At first glance, it has a flat, thin, galactic disk and a central bulge cut along the middle by regions of dark obscuring dust. The combined image data also reveal the galaxy's young blue star clusters and telltale pinkish star forming regions. And remarkably apparent in NGC 891's edge-on presentation are filaments of dust that extend hundreds of light-years above and below the center line. The dust has likely been blown out of the disk by supernova explosions or intense star formation activity. Faint neighboring galaxies can also be seen near this galaxy's disk. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1495667810173-5YUF9FE2EP6MAU33MVOE/NGC+4490+Astronomy.jpg Galaxies - NGC 4490, Cocoon Galaxy https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1603249729303-2M3SYYV286V90OG1AFYU/NGC1532Crop2T.jpg Galaxies https://www.hansonastronomy.com/nebula daily 0.75 2026-03-01 https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1719494262876-TRB3A6AUXIKBPX0P2CXK/image-asset.jpeg Nebula - NGC 2867 or Caldwell 90 NGC 2867- “A Rare Look” A rare view of this Planetary nebula shows the eerie shroud of HA and O3 surrounding the core of this PN. NGC 2867 (also known as Caldwell 90) is an elliptical Type II planetary nebula in the southern constellation of Carina, just over a degree to the NNW of the star Iota Carinae. John Herschel discovered the discovery on April 1, 1834. Herschel initially thought he might have found a new planet, but on the following night he checked again and discovered it had not moved. The nebula is located 7,270 light-years from the Sun. Caldwell 90 was formed in the late stages of the development of a Sun-like star. Following the nuclear fusion of hydrogen into helium in its core, the star underwent a series of energy crises when its supply of hydrogen began to decline. Without the outward force previously created by the energy production, gravity shifted and caused the star's core to contract. The extra pressure allowed the star to produce a heavier substance in its core. The synthesis of carbon produced a lot more energy than the fusion of hydrogen into helium, which enabled the star to not only overcome gravity to expand once more but led the star to become a red giant. Eventually the red giant’s outer layers of gas were ejected. Meanwhile, the star transformed from a cool giant into a hot, dense star that radiates ultraviolet light and a fast wind of particles that move outward at around 6 million miles per hour. The stellar wind and ultraviolet light interact with the layers of gas that the red giant ejected to create the glowing, spherical shell we see today.

This nebula even received six different classification numbers. Currently, astronomers call the entire nebula NGC 3576. A popular nickname is "The Statue of Liberty Nebula" because of the distinctive shape in the middle of the nebula. The name was first suggested in 2009 by Dr. Steve Mazlin, a member of Star Shadows Remote Observatory (SSRO). Explanation: An intriguing and beautiful nebula, NGC 3576 drifts through the Sagittarius arm of our spiral Milky Way Galaxy. Within the region, episodes of star formation are thought to contribute to the complex and suggestive shapes. Powerful winds from the nebula's embedded, young, massive stars shape the looping filaments. The dramatic false-color image also highlights the contributions of hydrogen, sulfur, and oxygen, energized by intense ultraviolet radiation, to the nebular glow. But the glow also silhouettes dense clouds of dust and gas. For example, the two condensing dark clouds near the top of the picture offer potential sites for the formation of new stars. NGC 3576 itself is about 100 light-years across and 9,000 light-years away in the southern constellation of Carina, not far on the sky from the famous Eta Carinae Nebula. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1719494262876-TRB3A6AUXIKBPX0P2CXK/image-asset.jpeg Nebula - NGC 2867 or Caldwell 90 NGC 2867- “A Rare Look” A rare view of this Planetary nebula shows the eerie shroud of HA and O3 surrounding the core of this PN.

It was given the popular name of the Toby Jug Nebula in 1979 after its appearance in colour photographs taken by David Malin at the Anglo-Australian Observatory. The central illuminating star it surrounds is the variable red giant V341 Carinae. Studies done by professional astronomers in the past attributed its formation to either mass loss or being ejected by an unseen companion. There is often difficulty in ascertaining the three dimensional structure of a nebula based on our two dimensional view of it. IC 2220 is likely to be both bipolar and biconical. Reflection nebulae surrounding red giant stars are scarce and the very few examples that are known happen to be a case of ambient interstellar matter in the surrounding region being illuminated. Despite the Toby Jug Nebula lying in a region of interstellar dust, it is unique that not only is it illuminated by a red giant but it has also been produced by it as well via mass loss. The visibility of the nebula is produced by dust grains reflecting the light of the star and it contains a mixture of elements with silicon dioxide being the most likely responsible for the reflection. Studies by professional astronomers in the past postulated that V341 Carinae was a former member of the open cluster NGC 2516 in the past. This association was based on both sharing similar distances. However in subsequent decades, better quality and more accurate astrometry data from the Hipparcos satellite showed that V341 Carinae had a much closer distance than NGC 2516 of 1200 light years while NGC 2516 has a distance of 1300 light years. However in the 21st century, more detailed observations are not exclusively reserved for the professional realm of astronomy. Through the proliferation of the internet and other technologies, it is possible for amateur astronomers to own or operate remote observatories. In fact, this image is the product of a remote observatory in Chile being operared by the image author in America. One such amateur astrophotographer called Josep Drudis who owns a remote observatory in Australia (along with a certain Don Goldman), with the assistance of his daughter Anna, serendipitously took hydrogen alpha exposures for IC 2220 in 2018 for the sake of curiosity and exploration. What was uncovered could not have been predicted, the presence of multiple overlapping arc shaped nebulosities and bubbles. Visually these are represented by the red waves of hydrogen gas visible in this deep image. Taking into account the well known history of V341 Carinae involving mass loss, these likely represent multiple episodes of mass loss prior to the event that generated the yellow reflection nebula. This is further supported by the separation of the various parts of the whole nebula. There is an absence of ionized hydrogen alpha emission coinciding with the reflection nebula as this is younger and more recent and probably not containing any hydrogen. Since V341 Carinae is known to be a red giant star with an age of 50 million years, it is not unreasonable to assume that the larger and older hydrogen bubbles represent the outer layers of the star that have been ejected in the past. As of March 2020, these enigmatic structures haven't been studied by professional astronomers yet. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1760801268764-NO0SMMJVXR48N6WLB0GC/image-asset.jpeg Nebula - Core of the Large Magellanic Cloud in RGBHa This remarkable image showcases the core of the Large Magellanic Cloud (LMC) as a highly detailed 16-panel mosaic covering more than 3.5 square degrees in the sky with 0.381 arc.sec./px.

Annotated version of the image: emission nebulae, SNR candidates and HII regions are shown in yellow ovals and markers (Tycho-2 catalog stars as also identified by the yellow markers); ISM shells and superbubbles shown in blue; star associations and star clusters shown in magenta; compact molecular clouds from various catalogs identified by white markers; compact dark nebulae are identified by the pink markers. The Large Magellanic Cloud is a dwarf galaxy and stands as one of the Milky Way's closest and most massive satellite galaxies. Visible to the naked eye from the Southern Hemisphere, the LMC appears as a hazy, luminous patch in the night sky. It is a highly dynamic region, well-known for intense star formation activity and hosting many interesting astronomical objects. Distance: Approximately 160,000 light-years from Earth Type: Dwarf irregular galaxy, with some signs of a barred spiral structure Size: About 14,000 light-years in diameter, roughly one-tenth the size of the Milky Way Star Count: Contains approximately 30 billion stars Location: Located in the southern constellations of Dorado and Mensa One of its most notable features is the Tarantula Nebula (30 Doradus) [1]: The largest and most luminous star-forming region in the Local Group of galaxies. If it were as close as the Orion Nebula), it would be bright enough to cast shadows. The LMC and the Small Magellanic Cloud (SMC) are gravitationally bound to each other and are engaged in a slow, intricate gravitational dance with the Milky Way. Recent studies indicate that the LMC may be a first-time visitor to our cosmic neighborhood, rather than a long-term satellite. This ongoing interaction is causing some of the LMC's outer halo of gas to be stripped away, though its dense core remains intact. Looking far into the future, a merger between the LMC and the Milky Way is anticipated to occur in about 2.4 billion years. SMC mosaic can be seen under [2]. The central region of the image containing Tarantula Nebula (30 Doradus) is sitting in the overlap of two LMC Supergiant Shells: LMC 3 and LMC 2 is shown in Fig. 2 (the location of other Supergiant Shells in the LMC is shown in [3, 4] and their structure described in more details in [5, 6]). This overlap is likely responsible for an extreme level of complexity if the emission nebulae structures in this region with added numerous compact neutral gas clouds sitting in front, behind and in between of them along the light of sight, resulting in beautiful patterns that require rather careful processing to preserve them in this high dynamic range scene. <Tarantula-16pane-RGBHa-more stars at2.jpg> Fig.2. Simplified annotated version of the image showing the high level structure of the region. Three sub-regions of in the center LMC 3 and LMC 2 Supergiant Shell overlap region are of particular interest here as shown in the cropped and cropped annotated versions or the original image shown in Fig. 3, Fig. 4 and Fig 5: Fig. 3 shows the area containing Tarantula Nebula (30 Doradus) and its immediate vicinity populated with numerous star clusters and star associations. The supernova remnant SN1986A [7] is also sitting on the boundary of LMC-N157 [8] HII region of unusual horseshoe shape in the upper left corner. Fig. 4 shows the area of the original image sitting above the one shown in Fig. 3, dominated by the DEM L261 [9] HII region hosting several star associations and the LMC-N158 [10] HII region on the right side of the cropped image that has multiple star clusters perfectly framed by the walls of the HII region. There are rather peculiar “double wall” ripple-like diffuse structures in the lower left corner of the frame. Fig. 5 continues the scan of the original image going in upward direction showing the area filled with multiple HII regions complete with several stand-alone SNRs in the middle top portion and the upper right corner of the frame.

Image Processing and Data Collection The image was processed and calibrated by Mark Hanson using advanced methods to ensure exceptional clarity and detail. The data for this mosaic was gathered by Hanson, Mazlin, Parker, and Forman in 2025. Observations were made using a 24-inch Planewave CDK telescope with an f/6.5 configuration, mounted on an L600, and a Moravian C5 camera located at El Sauce, Chile. The final mosaic consists of 16 panels, captured in Red, Green, Blue (RGB), and Hydrogen-alpha (Ha) bands, with binning at 2x2. In total, 960 R, G, B, Ha frames were taken, resulting in 100 hours of cumulative observation time so far, OIII and SII to follow. Enjoy this breathtaking view!

It is quite a dynamic and colorful area in the Southern sky. We have also added a labeled version for you to gaze at. NGC 2726-27 and IC 4812 - these most prominent intense blue areas (left center) are reflection nebulae which are clouds of interstellar dust lit up by the bright nearby stars. You can also see them illuminating areas quite far outside the actual Nebula’s themselves. NGC 2726-27 has the presence of a widely spaced double star, while IC 4812 features a much closer double star with two sets of diffraction spikes, indicating the presence of double star BrsO 14. Just to the left of NGC 2726 is a very exciting area, NGC 6729 a reflection/emission nebula located some 424 light-years away. This object is also a variable nebula, and the Coronet Cluster also known as R CrA. It was discovered by Johann Friedrich Julius Schmidt in 1861.This fan-shaped nebula opens from the star R Coronae Australis toward the star T CrA to the south-east. R CrA is a pre-main-sequence star in the Corona Australis molecular complex, one of the closer star-forming regions of the galaxy. Bernes 157 and SL 41 are areas called Dark Nebula interstellar clouds that are dense enough to obscure the light from behind. Bernes 157 (DN) is a boomerang shaped dark nebula that is 520 light years away. Herbig-Haro (HH) objects, named after astronomers George Herbig and Guillermo Haro, are high-velocity jets emitted by young stellar objects that interact with surrounding gas, generating shock waves and illuminated arcs. These jets can reach speeds between 100 and 1000 km/s, forming distinct luminous fronts within nebulae that persist for only a few thousand years. This image contains 35 examples of Herbig-Haro objects, HH 82 A-B, 96, 97, 98, 99 A-B-C, 100, 101, 101 S-N, 104, 104 D-C, 729 A-B-C, 730 A-B, 731 A-B, 732 A-B-C, 733, 734 A, 735 A-B, 736, 860, 861 A-B, 862. These objects are often mislabeled among amateur and even professional data, which makes it challenging to get a good map of them and their true locations, including several that remain unnamed or unclassified in literature. NGC 6723 (right center) colorful gem like globular cluster really compliments this field of view. This globular cluster cataloged as Dunlop 573, was discovered by James Dunlop in 1826 from New South Wales, Australia. Appearing near Corona Australis in Sagittarius, and it is located about 30,000 light-years away, beyond the Corona Australis dust cloud. There are quite a few small background galaxies present here as well. The labeled version shows all these objects and more. There are 3 areas: A, B and C that will require further study as they are unclassified or unnamed.

Infrared observations revealed numerous protostars, young stars, and Herbig-Haro objects; HH78 is seen as a red spot above the image center, in a dark cloud.

Its apparent diameter in the sky is 0.5 deg which corresponds to a linear size of about 12 ly at that distance. Numerous neutral gas clouds that are located at the distances as close as 850 ly belonging to the Serpens–Aquila Rift [9, 10] which extends over the range of distances from 750-1650 ly and alters the appearance of RCW 174 significantly in the visual spectrum compared to near-IR views [3, 4]. Several sub-regions of RCW 174 are of particular interest, such as the dense area surrounding star UCAC4 439-077030 [11] for which the Gaia DR3 [12, 13] parallax based distance estimate is 1661 ± 24 ly, so it is likely physically associated with the RCW 174 region. The Spitzer IR image [3, 4] reveals a system of bow shocks in the immediate vicinity of UCAC4 439-077030 [11], as illustrated in Fig. 1, even though its measured proper motion of 6.75 mas/yr corresponds to “only” 16 km/s per second of the linear speed, and the direction of motion is pointing away from those bow shocks. Thus, those shock fronts could be associated with one of the dimmer stars found in the vicinity. Two outflow structures MHO 3284 [14], MHO 3285 [15] are identified in this area in [16, 17] without pointing to a specific source for them. RCW 174 (Sh2-64, LBN90 and W40) HII region in Serpens Wonderful Description from: Alexander Zaytsev The subregion of interest here is near the center of NAME W 40 star cluster [18] / LBN 028.77+03.43 HII region [19] that are hosting several OB stars and numerous young stellar object candidates embedded into a dense portion of a molecular cloud [20-22]. Once again the Spitzer IR image [3, 4] reveals a complex internal structure of that cloud, with a lot of density variation that is practically invisible in the visual spectrum - as shown in Fig. 2. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1752853919463-D5UXYYX7MW9F83XDXG8X/image-asset.jpeg Nebula - RCW 105 or Gum 51 RCW 105 or Gum 51 RCW 105 (Also catalogued as Gum 51 ) is an emission nebula in constellation Norma. The nebula is surrounded by numerous small molecular clouds and is likely embedded in the compact OB association R105. The estimated distance for the R105 association is about 1580 parsecs and its age is 12.8 million years. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1750160642162-CVRC5VJBP39J9VAH9KSB/image-asset.jpeg Nebula - Batcave in Centaurus by Zaytsev and Hanson Batcave in Centaurus by Zaytsev and Hanson The HII region RCW 79 (GUM 48c, GRS G308.60 +00.60) [1, 2] embedded into a massive molecular complex of Centaurus has been studied extensively [3, 4], yet it remained a rarely imaged target which is often overlooked in favor of its neighboring RCW 78 (GUM 48b) HII region [5, 6]. Here we present a close-up look at RCW 79 with Chilescope Telescope #1 system that reveals a remarkably complex structure of the rim of this HII region, filled with lots of small dark nebulae, one of which resembles a certain character of popular fiction to such an extent that it prompted the choice of name for the scene [7, 8]. Fig. 1 and Fig. 2 point out the most notable features found in the rim of RCW 79. WIth distance to this HII region estimated as 5.3 ± 0.4 kpc [3, 4] the characteristic size of the HII region itself is only about 60 ly, the linear size of pillars 1 and 2 identified in FIg. 1 and Fig. 2 is about 1.3 ly, and the wingspan of the “Batman figurine” is about 13 ly. An open cluster Cl VDBH 151 [9] with measured parallax of 0.176 ± 0.013 mas is likely physically sitting inside the inner volume of the HII region, as its distance estimate of 5.7 ± 0.4 kpc based on that parallax is consistent with the distance estimate to RCW 79. Another visually striking feature of this scene is the “dark stream” crossing the area from top left side to lower central side consisting of multiple dark clouds elongated in the direction of the “stream”. This creates an illusion of the inner volume of RCW 79 to be lit from some external source at the top left side. The 4.5 mkm and 8 mkm IR imaging of this target by Spitzer [10-13] reveals more structures inside the rim of RCW 79, but most of the peculiar features listed above aren’t easily identifiable in IR images. Fig. 3 shows the Spitzer IRAC HEALPix survey color data [14] for the FOV of the image. As pointed in [9, 10] the RCW 79 remains an active star formation region with age estimated at 1.9 Myr [10, 11]. A compact (“only” about 9 ly across) HII region IRAS 13374-6130 [15] is emerging around one of those star formation sites, which is likely to open into the inner volume of the RCW 79 later during its evolution, resulting in a similar configuration as currently observed for Gum 48d - an older (about 4 Myr old) and less distant HII region in Cen [16, 17]. Overall, the RCW 79 turned out to be full of unexpected and visually striking features that deserve further study with large aperture systems.

The area also contains reflection nebulae VdBH 60a placed at an estimated distance of 1.9 kpc [8] and VdBH 60b both located at the “tip” of the elephant trunk nebula, as well as VdBH 60d and VdBH 60c reflection nebulae in the upper left corner.The angular size of the FOV in this image is 18’17” (side of the square) which for the distance of 1.9 kpc corresponds to the linear size of about 33 ly. Both earlier [3] and later [4, 5] studies conclude that the Stock 16 cluster has formed on the outer edge of the elephant trunk nebula which used to be larger prior to formation of the cluster. It is further derived [3] that that original (larger) elephant trunk nebula suffered an implosion triggered by the intense radiation from preceding generation of the OB stars from a cluster that is now dispersed over the larger area of the HII region, thus resulting in creation of the currently observable scene. It is also concluded that RCW 75 remains an active star formation region and that the site of next generation of stars “should lie in the dense dust clouds located along the ionization-bound edge of the complex” [3] pointing to the central stars of the four VdBH 60a-d reflection nebulae as possible newly formed objects. The image shows the unprecedented level of details in both dark nebulae in the middle and also in the “veil” preceding the ionization-bound edge of RCW 75 complex on the right of the trunk nebula, revealing many ghostly features there. A considerable amount of details is revealed in the part of the nebula complex on the left of the trunk nebula as well.

It is embedded in the Cometary Globule CG 12 and lit by a double star H4636 which are type B4 and B7 stars. Cometary globules are interstellar clouds with comet-like morphology, consisting of compact, dusty, and opaque heads and long, faintly luminous tails. Reflection nebulae are clouds of gas and dust that reflect the light from nearby stars. The starlight scatters through the gas and dust like a flashlight beam shining on mist in the dark and illuminates it. Imaged in LRGB on our Planewave CDK 700 at Observatorio El Sauce, Chile.

Many dark nebulae, open star clusters, and planetary nebulae are present in the scene, yet two most intriguing features found here are both associated with LHA 120-N 144 [3] HII region as highlighted in the cropped version of the image shown in Fig. 1: A faint elliptical arc that is fitted well by an ellipse with axis lengths of 360 ly x 940 ly (at the estimated distance to LMC of 158 kly) that is visible on one side of the region and marked as X1 in Fig 1. A set of compact shells approximately 56 ly across surrounding the red supergiant star HD 269551A [8] (which forms a binary system together with HD 269551B [9]) - marked as X2 in Fig 1. The HD 269551A [8] is the second largest star in the LMC with the physical radius estimated at 1439 solar radii (measured using photometric method based on data obtained from [10, 11]) which places it in TOP 15 on the list of the largest stars known to date. The structure of the compact nebula - multiple contric shells surrounding the HD 269551A [8] - suggests a physical connection to that star. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1743348619134-06N3FXNF4X9315MJL5HH/image-asset.jpeg Nebula - Gum 37 Gum 37 Gum 37, also known as RCW 54c, is a diffuse HII emission region located in the southern constellation of Carina, this region is often overlooked due to the brighter Statue of Liberty nebula in close proximity. Gum 37 includes the "Southern Tadpoles". The "tadpoles" refer to the elephant trunk-like tendrils of interstellar gas and dust, remnants of star formation. That giant "ear" at the top of the image is believed to be a planetary nebula or a remnant of the molecular cloud that formed the cluster. There is limited information available on this deep sky object The thin finger-like structures throughout the nebula are what immediately draws the eye in. These are highly compressed structures of molecular hydrogen that present a certain duality. On the one hand, the collapsing hydrogen is providing conditions for new star formation. On the other hand, the ultraviolet radiation from those newly formed stars is slowly eroding and destroying the nebula from within. Over time, this process will make the nebula disappear completely.

PCG 11 (PHR 1633-4928) Wolf-Rayet star and associated ring nebula [4-6] that has been named “The Jaws” by Logan Carpenter [7] who first introduced it to Astrobin back in 2023 [8, 9]. The earlier image obtained for this scene in H-alpha only with the same Chilescope T1 system back to 2024 is available under [10]. Many other diffuse structures and dark nebulae are visible across the frame, emphasized even better in the color compared to the H-alpha only view. Fig. 1 shows a cropped version of the image centered on WRAY 15-1508 at 200% of original resolution. According to [11] it is identified as a flat bipolar outflow planetary nebula, yet many additional structural features are revealed in this image, including a disruption in the “arms” of the nebula in the middle likely hinting the presence of a neutral gas disk in the middle. The distance estimate to WRAY 15-1508 given in [12, 13] based on Gaia EDR3 [14, 15] data is 2177 ± 233 pc, so the linear size of the “arms” of the nebula is about 0.33 px x 0.39 pc, and the gap in the middle is only 0.027 pc = 5.6 kAU wide. Fig. 2 shows a cropped version of the image centered on PCG 11 at 150% of original resolution. Based on the distance estimate to PCG 11 of 4100 ± 400 pc given in [5, 6] the linear size of the shell of the nebula is about 1.50 pc x 1.97 pc and the characteristic size of non-uniformities in the rim is just about 0.22 pc. According to [5, 6] the explanation for thee unusual disruptions of the ring structure on the inner side of the rim of PCG 11 is as follows: "Material at the inner boundary of that enveloping material suffers Rayleigh-Taylor instability. This appears as a highly regular scalloping of the inner margin of the nebulous Ha ring, defined by fingers of infalling ionized matter. There is a very well-defined wavelength for this phenomenon in PCG 11 and it is observed around the entire nebula rim." https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1741616971113-JN8A7GTBWL46MFFKED4K/image-asset.jpeg Nebula - Sharpless 293-295 "Falls of Blue" These spectacles of the universe Sh2-293 and SH2-295 look like blue waterfalls glistening and pouring down. Title: “Falls of Blue” Sharpless 293-295 The image is showing the region of sky off one of the wings of IC 2177 (Gum 2, RCW 1, Sh2-292, Seagull) [1] nebula located on the border of Monoceros and Canis Major constellations containing two HII regions (as shown on annotated version of the image in Fig. 1): Sh2-295 (LBN 1035) [2] in the lower left corner of the image, with the bright central star V* FZ CMa (HD 52942, a spectroscopic binary) [3] associated with the reflection nebula VdB90a. The V* FZ CMa itself is surrounded by the reflection nebula GN 07.00.3 [4]. Another reflection nebula VdB90b sitting on the boundary of this HII region is excited by the BD-11 1761 [5] - a star situated in the wing of the Seagull nebula outside of the FOV. The distance estimate to Sh2-295 given in [6, 7] is 2.28 ± 0.65 kly while the distance to V* FZ CMa based on Gaia parallactic measurements is 3.33 ± 0.16 kly. Sh2-293 (LBN 1030) [8] with bright central star HD 52721 (BD-11 1747, HIP 33868, GU CMa) [9] (a quadruple star system [10] with two other components identified as HD 52721A [11] and HD 5272B [12]) associated with reflection nebula VdB88 (upper right corner of the image). The distance estimate for Sh2-293 given in [6, 7] is 2.45 ± 0.65 kly while parallax based distance estimate to its main ionizing star HD 52721 using Hipparcos astrometric data [13, 14] is yielding 1.45 ± 0.77 kly with is still compatible with Sh2-293 distance estimate given a large systematic error on HD 52721 distance estimate (1.2 mas parallax error even after the reduction [13, 14]). Both HII regions are ionized by stars belonging to the CMa OB1 star association [15, 16] containing the CMa R1 association of reflection nebulae spanning across the region of the sky 2.5 deg x 1.6 deg across [17, 18]. The CMa R1 is nested in the “CMa shell” likely created by a sequence of supernova explosions that happened 1- 6 Myr ago [19, 20]. Fig. 2 shows the annotated version of the image with parallax data (in units of mas) available from the Gaia DR3 XPSD DB [21, 22]. Taking the distance to the scene at about 3 kly, the horizontal edges of the FOV correspond to 32.3 ly and 24.4 ly of linear distance. The other components of Seagull nebula such as IC 2177 and NGC 2327 are located at a significantly larger distance of 3.65 - 3.80 kly, so both Sh2-293 and Sh2-295 may be overlapping structures with respect to that larger CMa R1 scene. Great many compact neutral gas clouds can be identified on the background in the FOV: 32 molecular clouds from MWISP survey [23, 24] alone are in it, including [KKY2004] 6 molecular cloud [25] sitting on the right boundary of Sh2-295 HII region and likely responsible for the formation of the multilayer structure of the wall there. Numerous compact neutral gas clouds are also forming a rather complex structure of the wall of Sh2-293 HII region presented here in unprecedented level of details. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1740937768163-YQXZCPKLAA5CJ00TMM9N/Chamaeleon+Molecular+Cloud+Thumb.jpg Nebula - The Chamaeleon complex Ced 110 The Chamaeleon complex is a large star forming region (SFR) that includes the Chamaeleon I, Chamaeleon II, and Chamaeleon III dark clouds. It occupies nearly all of the constellation of Chamaeleon and overlaps into Apus, Musca, Carina and Octans. Chamaeleon 1 is one of the nearest active star formation regions and is around 700 light years away. Chamaeleon 2 contains over 40 X-ray sources while Chamaeleon 3 appears to have no star formation taking place.

Also known as the "Skull and Crossbones Nebula" is located in the constellation Puppis. Numerous stars and clusters come together to make this stunning stellar portrait. One of the most notable clusters within NGC 2467, known as Haffner 18, houses around 50 stars—most are high-mass, but have already begun the transit into the celestial afterlife. They certainly help shape the pillars of gas and dust, but their role is negligible compared to that of HD 6315 located in the center of NGC 2467. This gargantuan star does most of the work. Its outbursts, ranging from flares, to coronal mass ejections and such, eject vast quantities of radiation into the nebular material, which has a carving effect. The dark splotches all around and in the nebula are Bok Globules. Within these regions, dust is packed together so tightly, light from embedded stars can’t break through. 75 Hours of exposure https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1737157388256-WOWMBSD6D243KT9SOF21/image-asset.jpeg Nebula NGC 1833 and its surroundings in the LMC by Zaytsev and Hanson Here is a close look at the part of the LMC 8 supergiant shell [1-4] located South-West of the Large Magellanic Cloud (LMC) containing the LH24 OB star association [5] with NGC 1833 emission nebula [6] and NGC 1837 open cluster [7] enclosed within obtained with the Chilescope T1 system (ASA Ritchey-Chretien RC-1000: D=1m, f/6.8). Manually annotated version of the image is shown in Fig. 1. A wider angle view of this region near the LMC was also obtained earlier using the Chilescope T3 system (ASA-N D=0.5m, f/3.8) [8], yes significantly more details of internal structure are revealed here for the three main diffuse structures: NGC 1833 [6] showing a compact (8.4 ly across by the longer axis at estimated distance to LMC of 158 kly) neutral gas feature in the inner volume of the nebula shown in Fig. 2. DEM L 75 HII region [9] and nearby emission nebula complex also featuring another compact (5.8 ly across by the longer axis at estimated distance to LMC) neutral gas feature appearing to be fully surrounded by ionization fronts as shown in Fig. 3. A peculiar bipolar LHA 120-N 191 object [10, 11] consisting of a compact HII region on one side and a more diffuse emission nebula on the other side shown in Fig. 4. The range of linear scales for substructures for this region is 6-50 ly - estimated based on distance to the LMC. According to [10, 11] the start population physically associated with the compact HII region LHA 120-N 191A are “only” 3-8 Myr of age which accounts for the relative compactness and high density of this region. Fig. 5 shows the annotated cropped view of the central part of the image that contains besides NGC 1833 [6] and NGC 1837 [7] a peculiar elliptical asterism situated around SP77 40-9 [12] long-period variable candidate star that is about 67 ly away based on Gaia DR3 parallax measurements [13, 14]. The asterism was first identified in the Chilescope T3 image [8] and given a reference name of “LMC SH8 X1”. Remarkably so, the structure appears even more apparent in the Chilescope T1 image, and also more details of the background diffuse structures are visible in it as illustrated in Fig. 6 showing the region of interest at 200% of original resolution: Tiles (a) and (b) show the region in HOS colors with and without elliptical overlays showing where the main concentration of point-like sources forming the asterism. The dimensions of the overlays are 367px x 326px (in 100% of original resolution) = 100 arc.sec x 89 arc.sec (eccentricity 0.46) for the outer shell, and 290px x 257px (in 100% of original resolution) = 79 arc.sec x 70 arc.sec (also of eccentricity 0.46) for the inner shell. Tile (c) shows the same HOS color version with an overlay showing available parallax data based on Gaia DR3 XPSD DB [15, 16]. Only few stars in the elliptical band indicated have meaningful (positive) parallax values - these are shown with red underline - and these parallax values are in the range of 0.011 - 0.082 mas corresponding to 40 - 300 kly distance. The parallax of the central star SP77 40-9 [12] is measured as 0.0485 ± 0.0125 mas [17] corresponding to 67 ± 17 kly. Tile (d) shows the same scene with all diffuse components removed to emphasize the point-like sources component. Tiles (e) and (f) are showing the same scene in B&W with the attempt to run the aperture photometry analysis procedure with PixInsight on it. Most of the faint sources in the asterism aren’t picked up by this procedure. The angular diameter of the elliptical shells of 70-100 arc.sec correspond to 23 - 32 ly of linear size at the distance of 67 kly or 54 - 77 ly - at the distance to the LMC of 158 kly. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1734024884795-M0QNXCFGCCQ4E66SZZE2/image-asset.jpeg Nebula - NGC 2018 NGC 2018 This Chaotic Cluster of Gas an area within the Large Magellanic Cloud that is very rarely imaged, NGC 2018 is an emission nebula with a star cluster.

It is the largest and most complex star forming region in the entire galactic neighborhood. Located in the Large Magellanic Cloud, a small satellite galaxy orbiting our Milky Way galaxy, the region's spidery appearance is responsible for its popular name, the Tarantula nebula. This tarantula, however, is about 1,000 light-years across. Were it placed at the distance of Milky Way's Orion Nebula, only 1,500 light-years distant and the nearest stellar nursery to Earth, it would appear to cover about 30 degrees (60 full moons) on the sky. Intriguing details of the nebula are visible in the following images shown in colors emitted predominantly by hydrogen, oxygen and sulfur as well as red, green and blue. The spindly arms of the Tarantula nebula surround NGC 2070, a star cluster that contains some of the brightest, most massive stars known, visible in this butterfly like section of the image. Since massive stars live fast and die young, it is not so surprising that the cosmic Tarantula also lies near the site of the closest recent supernova. 3 versions of this nebula, all quite different.

Blinded by the trillions of stars lies the expansive area of emission nebula, Supernovas, Globular and open clusters. Image Processing: Mark Hanson Description: Alexander Zaytsev Enjoy, Mark & Alex This wonderful and extensive description buy Alexander Zaytsev Nebulae complexes and star clusters in the vicinity of Theta Dor The area in between Theta Dor [1] star and NGC 1871 open star cluster [2] in the vicinity of the Large Magellanic Cloud (LMC) contains an incredibly complex nebula complex comprised of HII regions, ionization fronts and supernova remnants (SNRs) that is complemented by other peculiarly shaped dim diffuse structures and the adornment of multiple globular and open star clusters stretching 40 arc.min West of Theta Dor. Since most of the diffuse structures in this frame belong to the LMC, the linear size of the sides of the image of 51.9 arc.min by 36 arc.min can be estimated as 1.82 kly by 1.26 kly at the distance to LMC taken as 158 kly. Fig. 1 shows the upper left corner of the original image containing Theta Dor and multiple HII regions, SNRs, and star clusters of which the most prominent ones are: A group of two adjacent HII regions DEM L 107 [3] and MCELS L-152 [4] in the vicinity of Theta Dor, containing what appears to be several neutral gas clouds with ionization fronts on the periphery (marked as (a) - (c) in Fig. 1). A pair of HII regions DEM L 99 [5] and DEM L 90 [6] less complex on internal structure. A pair of compact HII regions LHA 120-N 26 [7] and LHA 120-N 27 [8]. Compact SNR [FHW95] LMC B0512-6710 [9], Open star clusters BSDL 850 [10], KMHK 616 [11], and 2MASX J05113171-6658315 [12] of which the latter much resembles a globular cluster but appears to be fully resolved up to the core and is accompanied by a background galaxy 2MASS J05114560-6657411 [13]. It appears that Theta Dor has extensive nebulosity around it with a radially symmetrical component which might be physically related to that star. Since the estimated distance to Theta Dor is 490 ly, it is possible that there is an overlap of much closer nebular on top of more distant structures belonging to the LMC here. Fig. 2 shows the lower left portion of the of the original image containing the other two emission nebulae complexes connected to star associations NGC 1869 [14], NGC 1871 [15], and NGC 1873 [16] containing what appears to be two ionization fronts (marked as (a) and (b) in Fig. 2). In between of the two emission nebula complexes there appears to be a spherical region that could be identified as SNR LI-LMC 642 [17]. The other two prominent structures here are an emission nebula identifiable as LHA 120-N 30D [18] and a neutral gas cloud [LLS2019] 18 [19] sitting in the gap separating it from the outer wall of the nebula surrounding NGC 1871 star association. Fig. 3 shows the lower right portion of the of the original image in which the most noticeable objects are: Spread-around globular cluster NGC 1846 [20]. Open star clusters NGC 1842 [21] and NGC 1844 [22] that both resemble globular clusters, but getting resolved nearly to the core. Compact SNR B0509-67.5 [23-25] also known as “Red Bubble” [26] that much resembles a planetary nebula but shows the characteristic fine structure of shock fronts on its boundary in the image obtained by the HST and Chandra [27-29]. Small open star cluster H88 188 [30]. The estimated physical diameter of the “Red Bubble” SNR is 23 ly [26] and the age estimate for it is only 400 ± 120 years old [24, 25] which makes it one of the youngest known SNRs in the radius of 200 kly and also one of just a few SNRs for which the light echo age was ever measured [31, 32]. While the SNR B0509-67.5 might be the object that received most attention in the literature so far in this entire region, the structure of the nebule surrounding Theta Dor and NGC 1871 association deserves further exploration with large aperture instruments. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1728763158232-XQ1XFC9BF3JPU5DOBO2B/image-asset.jpeg Nebula - LHA 120-N55 emission nebula Title: LHA 120-N55 emission nebula complex by Zaytsev and Hanson North-East of the Large Magellanic Cloud (LMC), a peculiar combination interstellar shell, emission nebulae, and a collection of shock fronts forming a structure that we called earlier a “Flying Owl Nebula” is located, for which an earlier image was obtained using the Chilescope T3 system (ASA-N D=0.5m, f/3.8) [1]. Here we present the close-up view on one of them - the LHA 120-N55 emission nebula complex / N55 molecular cloud of the LMC [2, 3], obtained with the Chilescope T1 system (ASA Ritchey-Chretien RC-1000: D=1m, f/6.8) comprised of the following tightly coupled structures - also shown in Fig. 1: LHA 120-N55A star forming region [4], DEM L 228{a, b} HII regions [5] arranged into a bi-polar shape with a bridge in the middle, that appears to be a nebula associated with WBBe LH 72 13 Be star candidate [6]. Fig. 1. The central part of the image containing the following structures: (a) LHA 120-N55A star forming region [4] and (b) DEM L 228{a, b} HII regions [5] arranged into an unusual bi-polar shape with a bridge in the middle, that appears to be a nebula associated with WBBe LH 72 13 Be star candidate [6]. Shown at 100% of the original image resolution. As LHA 120-N55 physically belongs to the Large Magellanic Cloud (LMC) [2, 3], the linear size of the side of the image of 18.5 arc.min can be estimated as 650 ly at the distance to LMC taken as 158 kly. Fig. 2 shows the part of the image containing the DEM L 228{a, b} HII regions and WBBe LH 72 13 Be star candidate at 150% of the original resolution.Two most striking features here is the spiral structure of the formed out of neutral gas clouds inside the DEM L 228b region and the “bridge” connecting the DEM L 228{a, b} regions of the estimated physical length of about 13 ly at the distance to the LMC. There appears to be a neutral gas tendril present inside that compact nebula extending from the central star to the periphery of the nebula as well. Fig. 2. Part of the original image containing the DEM L 228{a, b} HII regions [5] and WBBe LH 72 13 Be star candidate [6]. Shown at 150% of the original image resolution. Fig. 3 shows the part of the image containing the LHA 120-N55A star forming region [4] hosting the LH 72 OB star association [7, 8] and a rather beautiful collection of compact neutral gas clouds, ionization fronts and shock fronts. The brightest stars of the LH 72 appear to have shock fronts or compact toroidal diffuse structures associated with them. The linear scale estimate for both structures is in the 9.4-9.7 ly range given the distance to the LMC. Fig. 3. Part of the original image containing the LHA 120-N55A star forming region [4], shown at 200% of the original image resolution. Shock front (a) and toroidal diffuse structure (b) associated with bright stars of the LH 72 OB association [7, 8]. The highest resolution image available up to date for this OB association is one obtained by the Hubble Space Telescope (HST) WFC2 / WFC3 instruments using Ha, UV and visual spectrum data [9]. Fig. 4 shows the cropped version of the original image at 200% resolution with the HST image [9] added as a semi-transparent overlay thus making it easy to identify all of the small structural features of this region detected in both images. This entire nebula complex is undoubtedly a good candidate for study with even larger apertures, particularly for the interior part of the LHA 120-N55A region and the compact nebula surrounding the WBBe LH 72 13.

Today we know this light was from a supernova, or exploding star, and record the expanding debris cloud as the Veil Nebula, a supernova remnant. This sharp telescopic view is centered on a western segment of the Veil Nebula cataloged as NGC 6960 but less formally known as the Witch's Broom Nebula. Blasted out in the cataclysmic explosion, the interstellar shock wave plows through space sweeping up and exciting interstellar material. Imaged with narrow band filters, the glowing filaments are like long ripples in a sheet seen almost edge on, remarkably well separated into atomic hydrogen (red) and oxygen (blue-green) gas. The complete supernova remnant lies about 1400 light-years away towards the constellation Cygnus. This Witch's Broom actually spans about 35 light-years. The bright star in the frame is 52 Cygni, visible with the unaided eye from a dark location but unrelated to the ancient supernova remnant.   https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1727019204817-MI24Z867WDD3440PJOUU/SH2-234+V2AOPDsmall.jpg Nebula - SH2-234 - IC 417 - Spider Nebula (SWO) IC 417 , sometimes known as Spider Nebula , is a large visible nebula visible in the constellation of Auriga ; it is linked to Stock 8 and is home to important star formation processes. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1724929775026-DV3N6D9J34SNX14PVD2D/image-asset.jpeg Nebula - Ced 90 or Sh2-297 in the Seagull Nebula Ced 90 or Sh2-297 in the Seagull Nebula Ced90 or Sh2-297 is an emission nebula in the constellation Canis Major. The region was catalogued in 1959 in the extended seconded edition of the Sharpless catalogue. This area of Canis Major is a very active area of new star formation. Studies in 1988 found that the bright star illuminating the nebula was 8th magnitude HD 53623 / HIP 34178 with spectral class B1II/III. Later in 2004 it was shown that there was embedded a cold but massive Young Stellar Object or YSO within Sh2-297 near the edge of one of the dark rifts. This object has been observed in the far-infrared, but it is so deeply embedded in an interstellar cloud that it is undetectable in shorter wavelength observations such as the Two Micron All Sky Survey (2MASS), leading it to be originally named “Unidentified young stellar object 1” or UYSO-1. It was further revealed that this unseen stellar source produces a carbon monoxide (CO) bipolar outflow with a total mass of 5.4 M☉ solar masses, while the surrounding extended envelope weighs 30 M☉–40 M☉. Some 96 other YSOs have been discovered to be part of Sh-297, having a mean age of one million years and range in masses between 0.3 M☉ and 2.0 M☉.[1] Many variable stars are also assigned with this nebula complex, including the three brightest: MW Ori, TT Ori and V559 Ori. Distance is estimated between 1.0 and 1.4 kpc. (3,300–4,600 ly.),[1] averaging 1.2 kpc. or 3,900 ly. This region was catalogued as part of the major clustering of reflection nebula as CMa R1 by van den Bergh in 1966.Reflection nebulas were identified on blue plates of the Palomar Sky Survey, with positive confirmation made by checking nebulosity on the red plates. It was again later catalogued as LBN 1037 or LBN 225.27-02.42 SWO at Dark Sky New Mexico 17”CDK Ha 630, Luminance 300, Red 280, Green 280, Blue 280 Enjoy, Mark https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1723651803861-8TX8PGINN4102TP387ZD/S-300small.jpg Nebula - Veil Nebula Simeis 3-210 (SWO) Veil Nebula (A) = Simeis 3-210 20 53 07 +29 39.0 Simeis 3-210 is a long, thin filament at the extreme southern end of the Veil Nebula and is virtually unknown (not listed separately in SIMBAD), although it is outlined on the U2000 and Millennium star atlases. Although much fainter than the other main sections of the Veil, Simeis 3-210 was easily picked up at 105x using an OIII filter as it passes through mag 6.4 HD 198976. This narrow strand is extended N-S at least 20' with the northern half mainly consisting of an elongated patch (~3'x1'), centered about 6' NNE of the bright star. The southern section is a very dim filament beginning at the mag 6.4 star though it brightens somewhat ~10' SSW of the star.

Open cluster NGC 3293 is located in the constellation Carina, lies at a distance of about 8000 light years, and has a particularly high abundance of these young bright stars. A study of NGC 3293 implies that the blue stars are only about 6 million years old, whereas the cluster's dimmer, redder stars appear to be about 20 million years old. If true, star formation in this open cluster took at least 15 million years. Even this amount of time is short, however, when compared with the billions of years stars like our Sun live, and the over-ten billion year lifetimes of many galaxies and our universe. Pictured, NGC 3293 appears just in front of a dense dust lane and red glowing hydrogen gas emanating from the Carina Nebula. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1715173423572-DCZ0AUSUYQMQSP987ZV1/image-asset.jpeg Nebula - Flying Owl Nebula Flying Owl Nebula of the LMC by Zaytsev and Hanson The area shown in this image is a part of LMC-4 superbubble is located North-East of the Large Magellanic Cloud (LMC) contains a rich collection of HII regions and supernova remnants (SNR) fitting in between the NGC 2041 globular cluster [1] and the NGC 2030 (also known as LMC N63 or LHA 120-N63) HII region [2].

Here we present the closer view to it obtained with the Chilescope T1 system (ASA Ritchey-Chretien RC-1000: D=1m, f/6.8) revealing its internal structure in much greater detail, using a similar color schema, but in different orientation and mirroring - aimed to increase the resemblance of the the scene to that of a flying owl. The size of the side of the image of 17.7 arc.min corresponds to 816ly at the distance to LMC taken as 158kly. The bubble in the middle of composition is identified as interstellar shell [KDS99] SGS 14 [14] which is 290ly across by a longer axis, to which multiple arcs of emission nebulae are connected. One of those arcs contains 3 shock fronts highlighted in Fig. 1, one of which appears to be related to the Brey 51 Wolf-Rayet star [15]. The origin for the other two fronts isn’t so easily identifiable. Several distant galaxies are showing up in the background of this image, the most notable of which is LEDA 178603 [17] also shown in Fig. 1. Fig. 1.

Located in Carina nebula, close to the more famous Gabriel Mistral Nebula and Gem Cluster. Wolf-Rayet stars are hot massive stars that are experiencing a normal evolution for very large stars where they lose orders of magnitude more solar mass each year in comparison to our Sun. They form a very strong solar wind that interacts with the interstellar medium, often producing "bubbles", as shown here. Wolf-Rayet stars are very rare stars in our Milky Way galaxy.

Lightyears of woven dust and gasses like a priceless work of art. It’s intricate details of shapes from pillars, mountains, caverns, and wispy intricate fragments. The colors are impressive as well, the blues from Oxygen, the reds from Hydrogen and the yellows from Sulfur. All together they look as if you’re peering into a kaleidoscope. Quite the sight. NGC 6357 also known as the Lobster Nebula and War and Peace Nebula is a large emission nebula located approximately 5,900 light-years away in the constellation Scorpius. The nebula contains many proto-stars (which are very young stars that are still gathering mass from their parent molecular cloud). These stars are shielded by dark discs of gas and wrapped in expanding "cocoons" or expanding gases surrounding these small stars. The nebula contains many unusually massive stars whose interstellar winds, powerful magnetic fields, gravity, and radiation pressures are carving complex structures in the surrounding dust and gas. The hot, luminous O-type stars are the main ionizing source in the area. The nebula hosts several massive young star clusters and is one of the most prominent star-forming regions in the southern sky. Open star cluster Pismis 24 near its center (left center in this image) is one of the brightest stars in the cluster, Pismis 24-1, was thought possibly to be the most massive on record, approaching 300 solar masses, until it was discovered to be a multiple system of at least three stars; component stars would still remain near 100 solar masses each, making them among the more massive stars on record.

There are approximately 500 or so of these Wolf-Rayet stars in our Milky Way galaxy, so that is not very many. These stars are evolved, massive stars that have completely lost their outer hydrogen and are fusing helium and heavier elements in the core. WR 102 is in its final stages of nuclear fusion, near or beyond the end of helium burning. It’s likely it only has a few thousand years to exist before it explodes.

RCW 89 is an emission nebula that contains a young supernova remnant and one of the most advanced pulsars in our galaxy. It is one of the most fascinating examples of how pulsars can create their surroundings with their powerful winds. This pulsar spins approximately 7 times per second and emits powerful jets of energy and particles that create a cloaked warbird-shaped structure.

According to the GCVS variability classification scheme [7] the CoKu HP Tau/G2 is an Orion type variable (“irregular, eruptive variables connected with bright or dark diffuse nebulae or observed in the regions of these nebulae”) located at a distance of about 161 pc as measured by VLBA using the direct parallax method [8, 9], at which distance the edge of the image frame corresponds to 2.7 ly = 169 kAU. Manually annotated cropped view to The CoKu HP Tau/G2 and CoKu HP Tau/G3 are believed to form a gravitationally bound system according to [8, 9] and on top of that both V* HP Tau and CoKu HP Tau/G3 were confirmed to be tight binaries by themselves based on lunar occultation data analysis under [10, 11] and the orbital solution for HP Tau/G3 can be found in [12, 13]. Thus, the CoKu HP Tau/G2 plus CoKu HP Tau/G3 system appears to be a hierarchical triple star system [8, 9]. Furthermore, treating the V* HP Tau plus CoKu HP Tau/G2 plus CoKu HP Tau/G3 as a wide triple system (intentionally neglecting tightly coupled components of V* HP Tau and CoKu HP Tau/G3) [14, 15] gives masses for its components as 0.94, 2.49, 0.72 Solar masses correspondingly, with separation between CoKu HP Tau/G2 and V* HP Tau determined to be 3089 AU and separation between CoKu HP Tau/G2 and Coku HP Tau/G3 determined to be 1463 AU. The age of these three stars is estimated to be in the range of only 3-8 Myr, with CoKu HP Tau/G3 being the youngest and CoKu HP Tau/G2 - the oldest in the group [8, 9]. The reflection nebula surrounding the HP Tau group consists of multiple concentric fronts of which the brightness drops and average radial width - increases as they move away from the central CoKu HP Tau/G2 (V1025 Tau) star. The curvature diameter of the smallest curved front features visible in the core of the nebula is about 0.043 ly = 2735 AU based on the estimated distance to the star from above. Another set of non-concentric fronts exists here as well, some of which seemingly associated with V* HQ Tau star located 5 arc.min away from HP Tau/G2 in the lower right part of the image frame. Many of the fronts are with peculiar 120 deg bends and junction points. The entire set of fronts is embedded in a dark cloud showing hints of an even more peculiar spiral structure reaching out to the edge of the frame. Simple attempt to fit the most prominent curved fronts in the central part of the image with circular shells centered (or nearly centered) on the stars belonging to the HP Tau group and the nearby stars visible in the FOV is given below in Fig. S2. Interestingly enough, some of those fit rather well (each circle is provided with the indicator of a center). Further study is needed to attempt a 3D reconstruction of this region and its relation to the Taurus Molecular Cloud situated in the range of distances between 130 and 160 pc according to [16, 17], so the V1025 Tau is actually expected to sit behind most of the structures of that dark cloud. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1706022337327-WPG2IGNRKK5P90VG9Q9I/image-asset.jpeg Nebula - The Carina Nebula and “The Lost Relics” The Carina Nebula and “The Lost Relics” The Carina nebula is one of the best known and most prominent nebulae in the Southern Sky also known as The Carina Nebula , Eta Carina Nebula NGC 3372as well as Great Carina Nebula .

The central part of the image is taken by the LHA 115-N 78 HII complex [1] which is about 160 ly across (linear equivalent at a distance to the SMC) featuring many accompanying structures including a planetary nebula candidate [2], open star cluster IC 1624 [3, 4] caught in the crossing of several shock fronts (shown in a cropped image below at 100% of original resolution), complete with great many small scale structures visible in the inner volume of the “main bubble” of the complex. One of the most noticeable of those small structures is a “torii gate” structure highlighted by red markings on the cropped image below (shown at 200% scale to the original resolution) which is only about 10 arc.sec across, but still corresponding to an impressive 9.6 ly of linear scale (given the distance to the SMC). This particular area could be of interest to study with larger aperture systems. The list of peculiar objects in this frame is continued by a compact DEM S131 HII region [5] at the top side of the image shown in a cropped image below (at 150% scale to the original resolution) with IKT 25 X-ray binary [6] in the middle which is identified as a Type Ia SNR in [7]. A larger but fainter Q-shaped diffuse structure is visible in the mid-left side of the frame, a part of which is identified as DEM S132 HII region [8]. Many dark nebulae are visible across the frame, many of which are surveyed under [9, 10], showing well against the backdrop of the inner volume of the HII regions. A noteworthy set of nested radial shock fronts is also found in the lower right corner.

The dust clouds effectively block light from distant background stars in the Milky Way. But the striking complex of reflection nebulae cataloged as NGC 6726, 6727, and IC 4812 produce a characteristic blue color as light from the region's young hot stars is reflected by the cosmic dust. The dust also obscures from view stars still in the process of formation. At the left, smaller yellowish nebula NGC 6729 bends around young variable star R Coronae Australis. Just below it, glowing arcs and loops shocked by outflows from embedded newborn stars are identified as Herbig-Haro objects. On the sky this field of view spans about 1 degree. That corresponds to almost 9 light-years at the estimated distance of the nearby star forming region.

It is powered by the irregular variable star, R Coronae Australis (R CrA). NGC 6726/6727 are blue reflection nebulae, where bright stars are embedded in a large cloud of dust which reflects the blue light of the stars. Herbig Haro objects are shown as small arcs of glowing gas. They originate as outflows from embryonic stars that are still forming inside the surrounding gas and dust.

This cloud overlays a rich field of background Milky Way stars. These background stars appear to be heavily "reddened" by the cloud's intervening dust. A large dark nebula extending throughout the region is cataloged Dobashi 12605,6. These areas of dense dust obscures background stars and other celestial objects. The bright blue central nebula shines from light reflected from the bright star designed HD 1706341. The blue color is a result of the surrounding dust reflecting the shorter wavelengths of light more efficiently than longer wavelengths. This is essentially the same phenomena that makes our Earthly sky appear blue. Standing out in contrast to VDB 123 just to the right of the blue vdB nebula is a red/orange bi-polar nebula known as the Serpens Reflection Nebula. (SNR)4 It is being illuminated by the relative low mass star designated Serpens/SVS 24. The nebula's outflow appears to be heavily influenced by embedded magnetic fields. This may have triggered the bi-polar shape of the nebula. Imaged in LRGB with our PlaneWave CDK 24 at Observatorio El Sauce, Chile.

The bulk of Coalsack nebula sits at a much closer distance of about 650 ly with the secondary dark clouds located as far as 10 kly in its corners [4, 5] but not where the RCW 71 is situated. Thus, RCW 71 gets most of the attenuation from that bulk of the Coalsack nebula and thus is easily detectable even on wide angle images of the area such as [6] as a bright red spot of about 2 arc. min in diameter. At the measured distance of 6.8 kly this angular diameter corresponds to the linear size of about 4 ly for the core (the HII region) of RCW 71. Earlier observations of this object by Midcourse Space Experiment (MSX) [7] revealed that it is surrounded by a ring of infrared emissions in the MSX A (8 mkm) spectral band [2, 3] for which the optical counterpart in Ha is revealed for the first time in this new image extending as far as 6 arc. min from the central star (HD 311999). Many additional details can be seen here in the core of the nebula such as two incomplete circles of dark nebulae filaments and what appears to be an ionization shock front about 1 arc.min away from the central star (above it in the specific orientation of the image). Another interesting feature revealed in the halo is what appears to be a thick dark filament stretching from the core of RCW 71 into the top right corner of the image which could be at least partially a denser part of Coalsack nebula overlapping with more distant structures. Unfortunately, the RCW 71 was just left out of the survey bands of Spitzer IRAC Equatorial Survey [8, 9] so further cross-referencing of the fine details of the optical counterpart of the halo in near-IR is difficult. However Herschel targeted this object over several observation sessions and produced details narrow FOV [10] and wide angle FOV [11] views of it in 100-160 mkm and 250-500 mkm spectral bands correspondingly that do confirm the presence of the diffuse halo around RCW 71 of up to 12 arc. min distance from the core of the nebula.

It has the designation NGC 2068 in the New General Catalogue. What is supersizing is how many other interesting objects are in this nebula. This patch of sky is absolutely gorgeous. It houses many Herbig-Haro (HH) objects are luminous regions surrounding newborn stars, formed when stellar winds or jets of gas spewing from these newborn stars form shock waves colliding with nearby gas and dust at high speeds.

All its gaseous colors and structures: twisting, looping, bubbling, and exploding onto the screen. Nemours globular clusters and millions of stars are also visible. What a beautiful site it is. The Small Magellanic Cloud (SMC) is a dwarf galaxy near the Milky Way. Classified as a dwarf irregular galaxy, SMC contains several hundred million stars. It has a total mass of approximately 7 billion solar masses. At about 200,000 light-years away from us, the SMC is among the nearest intergalactic neighbors of the Milky Way and is one of the most distant objects visible to the naked eye. The SMC is visible from the entire Southern Hemisphere but can be fully glimpsed low above the southern horizon from latitudes south of about 15° north. The galaxy is located across both the constellations of Tucana and part of Hydrus, appearing as a faint hazy patch resembling a detached piece of the Milky Way. The SMC has an average apparent diameter of about 4.2° (8 times the Moon's) and thus covers an area of about 14 square degrees (70 times the Moon's). Since its surface brightness is very low, this deep-sky object is best seen on clear moonless nights and away from city lights. The SMC forms a pair with the Large Magellanic Cloud (LMC), which lies 20° to the east, and like the LMC, it is a member of the Local Group. It is currently a satellite of the Milky Way but is likely a former satellite of the LMC.

The bubble associated with this SNR is estimated to be only 2.4 arc.min in diameter (140 ly linear size given the distance to the SMC), but it is also superimposed by the 5 arc.min in size (290 ly linear size) elongated shell (possibly a side of a larger bubble) [4, 5] thus forming a complex cascade of loops with a rather fine structure. This object was a target of several recent studies including [6] using the observations performed with XMM-Newton and Australia Telescope Compact Array (ATCA). The alternative explanation of this “cascade” structure suggested by [4, 5] is as a single large SNR bubble of which the spot identified as SNR B0050−72.8 is just a most active region in X-ray and radio-continuum parts of the spectrum. There are many fainter diffuse structures visible in the FOV some of which may comprise the walls of that hypothetical larger SNR bubble as well as more compact nebular and HII regions.

While its angular diameter is of about 8 arc.min, since it is physically bound to the SMC the linear size of the region is of about 465 ly while the side of the image is of linear size of about 1 kly at that distance. Due to its apparently twisted shape we call it a “little spindle” here despite its impressive linear size. The nebula is comprised of at least 5 overlapping bubbles associated with supernova remnants [1-5] with one more supernova remnant candidate [6] also identified by the Simbad Database for which the bubble either already dissipated or obscured by the rest of the structures . The “roof” of the nebula complex located at the top of the “spindle” is composed of an elaborate collection of shock fronts for which the origin is not so easily traced.

One of its most distinctive features, however, is the dark, starry gap called a “superbubble,” visible in this Hubble Space Telescope image in the upper central region. The hole is about 250 light-years wide and its presence is still something of a mystery. Stellar winds expelled by massive stars in the bubble's interior may have driven away the gas, but this is inconsistent with measured wind velocities in the bubble. Another possibility, since the nebula is filled with massive stars that would expire in titanic explosions, is that the expanding shells of old supernovae sculpted the cosmic cavern. Astronomers have found one supernova remnant in the vicinity of the superbubble and identified an approximately 5 million year difference in age between stars within and at the rim of the superbubble, indicating multiple, chain-reaction star-forming events. The deep blue area at about 5 o’clock around the superbubble is one of the hottest regions of the nebula and the area of the most intense star formation. N44 is an emission nebula, which means its gas has been energized, or ionized, by the radiation of nearby stars. As the ionized gas begins to cool from its higher-energy state to a lower-energy state, it emits energy in the form of light, causing the nebula to glow. Located in the Large Magellanic Cloud, N44 spans about 1,000 light-years and is about 170,000 light-years away from Earth. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1692725387216-7TRK621O3IKIMJ647I92/VDB4-Webcrop.jpg Nebula - VDB 4 - NGC 225 NGC 225 is an open cluster in the constellation Cassiopeia. One of it's stars, the variable star V594 Cas, illuminates the blue reflection nebula van den Bergh (vdB) 4, which also cataloged as LBN 604. It seems, that vdB 4 is a remnant from the cloud that formed the cluster. The name Sail Boat Cluster (NGC 225) was given to the open cluster located in the constellation of Cassiopeia by Rod Pommier, referring to the visual appearance of the object. There are a lot of gas and dust clouds around the cluster, part of which is being lit by the nearby cluster members, making it shine in blue. The cluster was discovered by Caroline Herschel in 1783, who entered the object as #11 on her private list of deep-sky objects. A few months later, in 1784, as a mistake, she discovered it again, and listed it again as object #15 on her list. The cluster visible in the constellation of Cassiopeia is a bit more than 2000 light-years away from us, by that distance the cluster is considered one of the nearby clusters to us. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1692237946568-ZX4TK11182PAQAAAF7Z9/CocoonNebula+Final.jpg Nebula - Cocoon Nebula, IC 5146 inside the Cocoon Nebula is a newly developing cluster of stars. Cataloged as IC 5146, the beautiful nebula is nearly 15 light-years wide, located some 4,000 light years away toward the northern constellation Cygnus. Like other star forming regions, it stands out in red, glowing, hydrogen gas excited by young, hot stars and blue, dust-reflected starlight at the edge of an otherwise invisible molecular cloud. In fact, the bright star near the center of this nebula is likely only a few hundred thousand years old, powering the nebular glow as it clears out a cavity in the molecular cloud's star forming dust and gas. This exceptionally deep color view of the Cocoon Nebula traces tantalizing features within and surrounding the dusty stellar nursery.     https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1691181081567-2I10JY4PP6A9ZOW7EVNO/image-asset.jpeg Nebula - RCW 103 Supernova Remnant RCW 103 Supernova Remnant The RCW catalogue was prepared by Alex Rodgers, Colin Campbell, and John Whiteoak, working at Mount Stromlo observatory under the direction of Dutch-American astronomer Bart Bok.

The star that caused this explosion was a star 8-10 times the size of our own sun and is now a neutron star not visible in visible wavelengths in this image. Recent Chandra X-Ray Observatory observations show a blue dot at the center which is interpreted as the neutron star formed in the explosion. This neutron star is quite special as it spins quite slow in caparison to most.

This beautiful nebula is considered one of the brightest and most massive star-forming regions in our galaxy. Sculpted by stellar winds and radiation, this fantastic colorful portrait of undulating shapes lies within this stellar nursery 5,500 light-years away in the Sagittarius constellation. What you see is the hot hydrogen gas that is illuminated when its particles are excited by the hottest of the stars that have just formed within the nebula. Also, some of the light is being reflected by the nebula’s own dust. These remain hidden by dark obscuring material, and we know their presence only through the detection of their infrared radiation. This image was taken from 2 different telescopes back in 2015 and in 2021. Over 75 Hours of exposure between them.

It's on the border of the constellations of Cepheus and Lacerta. It's estimated to be about 10,000 light years away. The star field is very rich, so the nebula is almost lost amidst all the stars. It’s home to Wolf-Rayet star WR153ab. These massive stars are nearing their transition to supernova or black hole. In the OIII wavelength there appears to be a river of blue gasses running up through the nebula. However, this river is actually part of a ring nebula being pushed by the WR star.www.hansonastronomy.com Taken from DGRO Rancho Hidalgo Animas, New Mexico in 2012 14.5" RCOS F8, Apogee U16M High Cooling HA 450, O3 480, S2 405min, Red 90, Green 90min ,Blue 90min, Calibrated,combined in PI and PS quite a difference from the old version done over 10 years ago. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1688303716294-040ON26HT0QH0VRWRTQL/image-asset.jpeg Nebula - NGC 1914 Labyrinth nebula NGC 1914 ("Labyrinth") nebula in HOS colors Description: A rarely looked upon compact (3’ in diameter) NGC 1914 nebula with embedded star association located near the Large Magellanic Cloud (LMC) with an elaborate and complex internal structure. The nebula appears to have two dim diffuse arms extending asymmetrically up to 10’ from the center. The “Labyrinth” name is proposed due to the seahorse shape dark nebula structure revealed on the inside. Only the brightest core feature (which is about 1.5’ across) is identified in DSS2 and other surveys, missing the details on the periphery. The way how this object may be connected with other diffuse objects found nearby [4] is to be studied further.

The surrounding nebula IC 405 is named the Flaming Star Nebula and the region seems to harbor smoke, but there is no fire. Fire, typically defined as the rapid molecular acquisition of oxygen, happens only when sufficient oxygen is present and is not important in such high-energy, low-oxygen environments. The material that appears as smoke is mostly interstellar hydrogen but does contain smoke-like dark filaments of carbon-rich dust grains. The bright star AE Aurigae, visible near the nebula center, is so hot it is blue, emitting light so energetic it knocks electrons away from atoms in the surrounding gas. When an atom recaptures an electron, light is emitted creating the surrounding emission nebula. In this cosmic portrait, the Flaming Star nebula lies about 1,500 light years distant, spans about 5 light years, and is visible with a small telescope toward the constellation of the Charioteer (Auriga).

The bluish reflection nebula with the two embedded double stars is IC 4601 (vdB 102,vdB 103), the yellowish reflection nebula is vdB 101. The two reflection nebulae appear so different due to the temperature differences of the illuminating stars. These types of nebulae are called “reflection,” because they reflect the light of nearby stars. IC 4601 is illuminated by the intense radiation of the stars present in its vicinity, among which the most brilliant star HD 147010, and the two stars of a binary system known as HD 147013, which are all blue giants. The dust of IC 4601 contains the heavy elements that planets are made of and plays a major role in the creation of new stars. There probably are baby stars wrapped in these blankets of dust.

Seen at the center of the cosmic cloud, the star is a mere 3 to 4 million years old. In another three to four million years the massive star will end its life in a supernova explosion. Spanning around 4 light-years, the nebula itself has a bipolar symmetry. That makes it similar in appearance to more common and familiar planetary nebulae - the gaseous shrouds surrounding dying sun-like stars. Also like many planetary nebulae, NGC 6164 has been found to have an extensive, faint halo, revealed in this deep telescopic image of the region. Expanding into the surrounding interstellar medium, the material in the halo is likely from an earlier active phase of the O star. The gorgeous skyscape is a composite of extensive narrow-band image data, highlighting glowing atomic hydrogen gas in red and oxygen in blue hues, with broad-band data for the surrounding starfield. NGC 6164 is 4,200 light-years away in the right-angled southern constellation of Norma.

Churning and mixing interstellar clouds of gas and dust, stars -- most notably those upwards of tens of times the mass of our Sun -- leave their mark on the compositions and locations of future generations of stars. Dramatic evidence of this is illustrated in our neighboring galaxy, the Large Magellanic Cloud (LMC), by the featured nebula, Henize 70 (also known as N70 and DEM301). Henize 70 is actually a luminous superbubble of interstellar gas about 300 light-years in diameter, blown by winds from hot, massive stars and supernova explosions, with its interior filled with tenuous hot and expanding gas. Because superbubbles can expand through an entire galaxy, they offer humanity a chance to explore the connection between the lifecycles of stars and the evolution of galaxies. An Amazing Explorer’s Legacy – the Henize Objects. In a recent project my astrophotography group, using a 24” Planewave telescope high in the Andes in Chile, targeted the object known as Henize 70. The image below is the result of this effort. From this I became curious about the history of the Henize objects. The astronomer Karl Henize spent years studying the Large Magellanic Cloud (LMC), the dwarf galaxy nearest us visible only from the southern hemisphere. He created a catalog of interesting objects in it during his career as Professor of Astronomy at Northwestern University. In 1967 he gave up his full professorship to became an Apollo astronaut and was actually slated to fly on Apollo 20 or 21 had the NASA project not been discontinued. In 1985 he finally did go into space on the Space Shuttle Challenger with the SpaceLab2 experiment. Henize had a lifelong interest in the LMC and created the catalog of interesting objects now bearing his name. Exploration was his game, and ultimately how he went out – at age 70 in 1994 he died climbing Mount Everest, where his body was buried at 22,000 ft.

In fact, the Crab is now known to be a supernova remnant, debris from the death explosion of a massive star, witnessed by astronomers in the year 1054. These sharp, ground-based telescopic views, combines broadband color data with narrowband data that tracks emission from ionized sulfur, hydrogen, and oxygen atoms to explore the tangled filaments within the still expanding cloud. One of the most exotic objects known to modern astronomers, the Crab Pulsar, a neutron star spinning 30 times a second, is visible as a bright spot near the nebula's center. Like a cosmic dynamo, this collapsed remnant of the stellar core powers the Crab's emission across the electromagnetic spectrum. Spanning about 12 light-years, the Crab Nebula is a mere 6,500 light-years away in the constellation Taurus.

Such stars exist, and some are known as Wolf Rayet (WR) stars, named after French astronomers Charles Wolf and Georges Rayet. The central star in this image is WR 40 which is located toward the constellation of Carina. Stars like WR 40 live fast and die young in comparison with the Sun. They quickly exhaust their core hydrogen supply, move on to fusing heavier core elements, and expand while ejecting their outer layers via high stellar winds. In this case, the central star WR 40 ejects the atmosphere at a speed of nearly 100 kilometers per second, and these outer layers have become the expanding oval-shaped nebula RCW 58. This just looks like you can hear it sizzling! RCW58, an E type nebula, is a Wolf Rayet Bubble formed by the ejecta from WR 40, the central star in the image. These three-dimensional bubbles appear as a ring in two dimensions, as seen in this image and represent the stellar ejecta contained in a windblown bubble. The are several similar WR ring nebulae are known including: MI-67, RCW104, RCW78, NGC3199, NGC6888. H alpha and OIII emissions from eight of the most well defined Wolf Rayet ring nebulae in the Galaxy reveal that in many cases the outermost edge of the OIII emission leads the H alpha emission. This suggests that these offsets, when present, are due to the shock from the Wolf Rayet bubble expanding into the circumstellar envelope.

The pinkish nebula on the middle left, known as NGC 2014, is an ionized gas cloud comprised almost entirely of hydrogen. A cluster of stars are responsible for the characteristic glow accompanying the ionization. When the stellar winds pierced through the galaxy, hydrogen atoms were stripped of their electrons when they came in contact with ultraviolet radiation streaming from young, energetic stars . The clouds of gas were then reborn when the hydrogen and their electrons recombined. Its blueish partner (pictured on the right) is NGC 2020. Its bubble-like cavity was naturally carved out as gaseous material was carried away by stellar winds.In contrast to NGC 2014, the bluish hue seen here is the work of one single, massive, unstable star called a Wolf-Rayet star. Instead of acting as an agent for the ionization of hydrogen, this star is responsible for ionizing surrounding oxygen atoms.

It must have been quite an explosion and the light would have reached earth around 11,000 years ago. The Vela Supernova Remnant spans the equivalent of 16 times the diameter of the Moon but is very faint and requires considerable exposure time on a suitable telescope to resolve it. The Remnant consists of gas and dust. Much of the gas is hydrogen and Oxygen, some of which has formed filamentary structures. The gas and dust has continued to expand outwards creating what we see today. It is thought that within the Vela Supernova Remnant there are the remains of an earlier supernova.

The diffuse emission nebula lies near the constellation’s northern border with Scutum. Also known as the Swan Nebula, Lobster Nebula, Horseshoe Nebula and Checkmark Nebula, the Omega Nebula is one of the brightest star-forming nebulae of the Milky Way. Its designation in the New General Catalogue is NGC 6618. M17 is also one of the most massive H II regions of our galaxy. Messier 17 is located in the Sagittarius Arm of the Milky Way, the next inward spiral arm to our own, and may be part of the same giant cloud complex as its close neighbor, Messier 16 (the Eagle Nebula), located in the constellation Serpens.

It is classified as an emission nebula and as an H II region. The Lagoon Nebula was discovered by Giovanni Hodierna before 1654[4] and is one of only two star-forming nebulae faintly visible to the eye from mid-northern latitudes. Seen with binoculars, it appears as a distinct oval cloudlike patch with a definite core. Within the nebula is the open cluster NGC 6530.[5] Lagoon Nebula in HaRGB The Lagoon Nebula is estimated to be between 4,000-6,000 light-years away from the Earth. In the sky of Earth, it spans 90' by 40', which translates to an actual dimension of 110 by 50 light years. Like many nebulas, it appears pink in time-exposure color photos but is gray to the eye peering through binoculars or a telescope, human vision having poor color sensitivity at low light levels. The nebula contains a number of Bok globules (dark, collapsing clouds of protostellar material), the most prominent of which have been catalogued by E. E. Barnard as B88, B89 and B296. It also includes a funnel-like or tornado-like structure caused by a hot O-type star that emanates ultraviolet light, heating and ionizing gases on the surface of the nebula. The Lagoon Nebula also contains at its centre a structure known as the Hourglass Nebula (so named by John Herschel), which should not be confused with the better known Engraved Hourglass Nebula in the constellation of Musca. In 2006 the first four Herbig–Haro objects were detected within the Hourglass, also including HH 870. This provides the first direct evidence of active star formation by accretion within it.[2] https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1628538962306-10GYIM4FJ0OZOR7C338C/NGC6357HansonT.jpg Nebula - NGC 6357 War and Peace Nebula - Lobster Nebula NGC 6357 War and Peace Nebula - Lobster Nebula Taken from SWOS in El Sauce, Chile 24” PlaneWave CDK Explanation from APOD: Why is the Lobster Nebula forming some of the most massive stars known? No one is yet sure. Cataloged as NGC 6357, the Lobster Nebula houses the open star cluster Pismis 24 near its center -- a home to unusually bright and massive stars. The overall blue glow near the inner star forming region results from the emission of ionized hydrogen gas. The surrounding nebula, featured here, holds a complex tapestry of gas, dark dust, stars still forming, and newly born stars. The intricate patterns are caused by complex interactions between interstellar winds, radiation pressures, magnetic fields, and gravity. NGC 6357 spans about 400 light years and lies about 8,000 light years away toward the constellation of the Scorpion. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1628538783824-Y82LZ0KT7JOPO45AOMUV/CatsPawNeb-LRGBHAO3S2-80T.jpg Nebula - NGC 6334 Explanation via APOD: Nebulas are perhaps as famous for being identified with familiar shapes as perhaps cats are for getting into trouble. Still, no known cat could have created the vast Cat's Paw Nebula visible in Scorpius. At 5,500 light years distant, Cat's Paw is an emission nebula with a red color that originates from an abundance of ionized hydrogen atoms. Alternatively known as the Bear Claw Nebula or NGC 6334, stars nearly ten times the mass of our Sun have been born there in only the past few million years. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1619442709188-8E2WVKMOOCF5Q0POQEAH/NGC6726V-3.jpg Nebula - NGC 6726 Cosmic dust clouds sprawl across a rich field of stars in this sweeping telescopic vista near the northern boundary of Corona Australis, the Southern Crown. Less than 500 light-years away the dust clouds effectively block light from more distant background stars in the Milky Way. The entire frame spans about 2 degrees or over 15 light-years at the clouds' estimated distance. Near center is a group of lovely reflection nebulae cataloged as NGC 6726, 6727, 6729, and IC 4812. A characteristic blue color is produced as light from hot stars is reflected by the cosmic dust. The dust also obscures from view stars in the region still in the process of formation. Smaller yellowish nebula NGC 6729 surrounds young variable star R Coronae Australis. Below it are arcs and loops identified as Herbig Haro objects associated with energetic newborn stars. Magnificent globular star cluster NGC 6723 is at the right. Though NGC 6723 appears to be part of the group, its ancient stars actually lie nearly 30,000 light-years away, far beyond the young stars of the Corona Australis dust clouds. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1618275817092-U58ZUYBIFCYR59VVMU9M/ConeThumb.jpg Nebula - The Cone Nebula Explanation: Strange shapes and textures can be found in neighborhood of the Cone Nebula. The unusual shapes originate from fine interstellar dust reacting in complex ways with the energetic light and hot gas being expelled by the young stars. The brightest star on the right of the above picture is S Mon, while the region just above it has been nicknamed the Fox Fur Nebula for its color and structure. The blue glow directly surrounding S Mon results from reflection, where neighboring dust reflects light from the bright star. The orange glow that encompasses the whole region results not only from dust reflection but also emission from hydrogen gas ionized by starlight. S Mon is part of a young open cluster of stars named NGC 2264, located about 2500 light years away toward the constellation of Monoceros. The origin of the mysterious geometric Cone Nebula, visible on the far left, remains a mystery. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1618237267775-3LAKZK0J8RZHOY61OYQR/NGC+3324Thumb.jpg Nebula - NGC 3324- Gabriela Mistral Nebula NGC 3324- Gabriela Mistral Nebula Description via APOD. Explanation: This bright cosmic cloud was sculpted by stellar winds and radiation from the hot young stars of open cluster NGC 3324. With dust clouds in silhouette against its glowing atomic gas, the pocket-shaped star-forming region actually spans about 35 light-years. It lies some 7,500 light-years away toward the nebula rich southern constellation Carina. A composite of narrowband image data, the telescopic view captures the characteristic emission from ionized sulfur, hydrogen, and oxygen atoms mapped to red, green, and blue hues in the popular Hubble Palette. For some, the celestial landscape of bright ridges of emission bordered by cool, obscuring dust along the right side create a recognizable face in profile. The region's popular name is the Gabriela Mistral Nebula for the Nobel Prize winning Chilean poet.

It is estimated to be only 300,000 years old. Stars, the Sun included, were born within clouds of dusty gas such as the Trifid Nebula. This young nebula contains enough material to make many thousands of suns. Within it a number of young hot stars have already formed. The Trifid Nebula, meaning ‘divided into three lobes’, is an unusual combination of a red emission nebula with a young open star cluster near its center, surrounded by a blue reflection nebula which is particularly conspicuous to the northern end, and a dark absorption nebula (the apparent ‘gaps’ within the emission nebula that cause the trifid appearance; these are also designated Barnard 85). The hydrogen molecules in the emission nebula at the Trifid’s core is heated by hundreds of brilliant young stars causing it to emit red light. The dense part of the nebula is a stellar nursery full of embryonic stars (NASA’s Spitzer Space Telescope discovered 30 embryonic stars and 120 newborn stars, not seen in visible light images). The star cluster, known as C 1759-230, may well be the youngest star cluster in our Milky Way galaxy. The blue color of the reflection nebula comes from cosmic dust grains which preferentially reflect the blue component of starlight as it scatters light from bright new stars that were formed nearby. The largest and hottest of these stars shines most brightly in the hot, blue portion of the visible spectrum. In some parts of the nebula there are so many dust grains that they hide the glowing gas, producing the dark absorption lanes, which were created in the atmospheres of cool giant stars and in the debris from supernovae explosions. Within these dark lanes, the remains of previous star births and deaths continue to collapse under gravity’s unrelenting attraction. The rising density, pressure and temperature inside these dark blobs will eventually trigger the formation of new stars. Close-up images show a finger-like stalk in the emission nebula that points from the head of a very dense cloud directly toward the star that powers the Trifid nebula, which is actually a triple system of extremely hot stars. This stalk is a prominent example of evaporating gaseous globules, or ‘EGGs’. The stalk has survived because its tip is a knot of gas that is dense enough to resist being eaten away by the powerful radiation from the star.

The superbubble structure of N44 itself is shaped by the radiation pressure of a 40-star group located near its center; the stars are blue-white, very luminous, and incredibly powerful.[6][1] N44F has been shaped in a similar manner; it has a hot, massive central star with an unusually powerful stellar wind that moves at 7 million kilometers per hour. This is because it loses material at 100 million times the rate of the Sun, or approximately 1,000,000,000,000,000 tons per year. However, varying density in the N44 nebula has caused the formation of several dust pillars that may conceal star formation.[6] This variable density is likely caused by previous supernovae in the vicinity of N44; many of the stars that have shaped it will eventually also end as supernovae. The past effects of supernovae are also confirmed by the fact that N44 emits x-rays.[4][8] N44 is classified as an emission nebula because it contains large regions of ionized hydrogen. However, the three strongest emission lines in the nebula are singly ionized oxygen atoms, which emit at an ultraviolet wavelength of 372.7 nm, doubly-ionized oxygen atoms, which emit at a blue-green wavelength of 500.7 nm, and neutral hydrogen atoms, which emit the hydrogen-alpha line at a red wavelength of 656.2 nm.[1][9] References https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1600733913175-3CX5PO0RHLKUXT2Z091L/IC1248-3T.jpg Nebula - IC 1284 IC 1284 IC 1284 (bottom left) and NGC 6590 (lower-mid right) There is hardly any background sky in this very dusty part of the southern Milky Way.

It was discovered by Gottfried Kirch in 1681. Charles Messier included it in his catalogue of diffuse objects in 1764. Its popular name derives from the brighter stars forming a triangle which could resemble a flying flock of ducks (or, from other angles, one swimming duck). The cluster is located just to the east of the Scutum Star Cloud midpoint. The Wild Duck Cluster is one of the richest and most compact of the known open clusters. It is one of the most massive open clusters known, and it has been extensively studied. Its age has been estimated to about 316 million years.

H alpha and OIII emissions from eight of the most well defined Wolf Rayet ring nebulae in the Galaxy reveal that in many cases the outermost edge of the OIII emission leads the H alpha emission.

The transient occurred in the direction of Alpha Centauri, between the constellations Circinus and Centaurus, centered at RA 14h 43m Dec −62° 30′, in Circinus. This "guest star" was observed by Chinese astronomers in the Book of Later Han ,and might have been recorded in Roman literature. It remained visible in the night sky for eight months. This is believed to be the first supernova for which records exist. The gaseous shell RCW 86 is probably the supernova remnant of this event and has a relatively large angular size of roughly 45 arc minutes (larger than the apparent size of the full moon, which varies from 29 to 34 arc minutes). The distance to RCW 86 is estimated to be 9,100 light-years). Recent X-ray studies show a good match for the expected age.

Reflecting the light of nearby hot stars, NGC 2170 is joined by other bluish reflection nebulae, a red emission region, many dark absorption nebulae, and a backdrop of colorful stars. Like the common household items that still life painters often choose for their subjects, the clouds of gas, dust, and hot stars featured here are also commonly found in this setting -- a massive, star-forming molecular cloud in the constellation of the Unicorn (Monoceros). The giant molecular cloud, Mon R2, is impressively close, estimated to be only 2,400 light-years or so away. At that distance, this canvas would be over 60 light-years across.

It is one of the most active star formation regions in the nearby Universe. It is one of the largest and most spectacular star-forming regions within the Large Magellanic Cloud (LMC), the largest satellite galaxy of our Milky Way. In fact, it is the second largest, only surpassed in the size and activity by the Tarantula nebula (or 30 Doradus), located at the opposite side of the LMC. The dramatic and colorful features visible in the nebula are the telltale signs of star formation. A leading hypothesis for the formation of NGC 1760 is that several successive generations of stars, each of which formed further away from the center of the nebula than the last, have created shells of gas and dust. These shells were blown away from the newborn stars in the turmoil of their energetic birth and early life, creating the ring- and bean-like shapes so prominent in this image. In NGC 1760 altogether, three generations of stars can be found. ‘Grandmother’ stars that have carved a large superbubble, leading to the birth of the cluster of massive bright blue-white ‘mother’ stars (NGC 1761) in the center. These in turn gives birth to new star ‘babies’ inside the dark globules. NGC 1761 (also designated LH9) is composed of about 50 massive hot young stars that emit intense ultraviolet radiation that has eroded a large hole in their surroundings. These stars are among the most massive stars known anywhere in the Universe. The bright region just above center is N11B, another explosive domain where stars are being formed even today. Although the Large Magellanic Cloud is much smaller than our own Milky Way, it is an active star-forming galaxy. Studying these stellar nurseries helps astronomers understand a lot more about how stars are born and their ultimate development and lifespan.

The nebula is approximately 8,500 light-years (2,600 pc) from Earth. The nebula has within its boundaries the large Carina OB1 association and several related open clusters, including numerous O-type stars and several Wolf–Rayet stars. Carina OB1 encompasses the star clusters Trumpler 14 and Trumpler 16. Trumpler 14 is one of the youngest known star clusters at half a million years old. Trumpler 16 is the home of WR 25, currently the most luminous star known in our Milky Way galaxy, together with the less luminous but more massive and famous Eta Carinae star system and the O2 supergiant HD 93129A. Trumpler 15, Collinder 228, Collinder 232, NGC 3324, and NGC 3293 are also considered members of the association. NGC 3293 is the oldest and furthest from Trumpler 14, indicating sequential and ongoing star formation. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1580913555258-YHFHM2MQH6B2V7COCMWM/NGC-2020-180-80small.jpg Nebula - NGC 2020 Two unlikely nebulae located side-by-side. The pinkish nebula on the middle bottom, known as NGC 2014, is an ionized gas cloud comprised almost entirely of hydrogen. A cluster of stars are responsible for the characteristic glow accompanying the ionization. When the stellar winds pierced through the galaxy, hydrogen atoms were stripped of their electrons when they came in contact with ultraviolet radiation streaming from young, energetic stars . The clouds of gas were then reborn when the hydrogen and their electrons recombined. Its blueish partner (pictured on the bottom right) is NGC 2020. Its bubble-like cavity was naturally carved out as gaseous material was carried away by stellar winds.In contrast to NGC 2014, the bluish hue seen here is the work of one single, massive, unstable star called a Wolf-Rayet star. Instead of acting as an agent for the ionization of hydrogen, this star is responsible for ionizing surrounding oxygen atoms. (Hence the variation in color) The rose-like Dragon Head Nebula NGC 2032/2040 is pictured to the left.

LDN 43 has received lots of attention from professional astronomers seeking to understand the mysteries of star formation. It is one of the closest star forming regions with a distance of slightly more than 500 light years. The area around it suffers from a high degree of dust extinction. This is best illustrated by the interstellar reddening of the majority of the stars in this image as well a few distant background galaxies. Any light travelling from these sources passes through this veil of dust, which absorbs the blue light making everything appear more red than it actually is. Interstellar dust extinction is prevalent in many parts of the Milky Way and many galaxies would shine more brightly if not for this intervening dust. Observations with radio telescopes have uncovered multiple molecular outflows in the vicinity of RNO 91, which are an indicator of the energetic activity of nascent YSO's. The outflows have carved out a cavity in the surrounding dark cloud, which is illuminated by the source of RNO 91, a type of YSO known as a T Tauri star. This is known to be encircled by a protoplanetary disk, which is a solar system in the making. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1572800225347-TCRHGK63ILHMXHLKJD5W/Tulip-WebT.jpg Nebula - Tulip Nebula Explanation: Framing a bright emission region, this telescopic view looks out along the plane of our Milky Way Galaxy toward the nebula rich constellation Cygnus the Swan. Popularly called the Tulip Nebula, the reddish glowing cloud of interstellar gas and dust is also found in the 1959 catalog by astronomer Stewart Sharpless as Sh2-101. About 8,000 light-years distant and 70 light-years across the complex and beautiful nebula blossoms at the center of this composite image. Ultraviolet radiation from young energetic stars at the edge of the Cygnus OB3 association, including O star HDE 227018, ionizes the atoms and powers the emission from the Tulip Nebula. HDE 227018 is the bright star near the center of the nebula. Also framed in the field of view is microquasar Cygnus X-1, one of the strongest X-ray sources in planet Earth's sky. Driven by powerful jets from a black hole accretion disk, its fainter visible curved shock front lies above and right, just beyond the cosmic Tulip's petals https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1572440124892-XAYBYYLEQX79WWZNVUUN/DWB18-3Thuimb.jpg Nebula - DWB-18 DWB-16 https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1567873487140-VQFWVHBNS0UYAFZ4MC0G/CasAThumb.jpg Nebula - Cassiopeia A Explanation: Massive stars in our Milky Way Galaxy live spectacular lives. Collapsing from vast cosmic clouds, their nuclear furnaces ignite and create heavy elements in their cores. After a few million years, the enriched material is blasted back into interstellar space where star formation can begin anew. The expanding debris cloud known as Cassiopeia A is an example of this final phase of the stellar life cycle. Light from the explosion which created this supernova remnant would have been first seen in planet Earth's sky about 350 years ago, although it took that light about 11,000 years to reach us. This false-color image, composed of X-ray and optical image data from the Chandra X-ray Observatory and Hubble Space Telescope, shows the still hot filaments and knots in the remnant. It spans about 30 light-years at the estimated distance of Cassiopeia A. High-energy X-ray emission from specific elements has been color coded, silicon in red, sulfur in yellow, calcium in green and iron in purple, to help astronomers explore the recycling of our galaxy's star stuff. Still expanding, the outer blast wave is seen in blue hues. The bright speck near the center is a neutron star, the incredibly dense, collapsed remains of the massive stellar core. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1554159474084-PC0NM2W0JM6Q8QYD9ABG/NGC+104+LRBB70smallAPOD.jpg Nebula - 47 Tucanae or NGC 104 47 Tucanae or NGC 104 47 Tucanae is the second brightest globular cluster after Omega Centauri, and telescopically reveals about ten thousand stars, many appearing within a small dense central core.

William Herschel included his sister's discovery in his catalog, and labeled it H VIII.77. It is also known as 142 in the 1959 Sharpless catalog (Sh2-142). This reasonably large nebula is located in Cepheus. It is extremely difficult to observe visually, usually requiring very dark skies and an O-III filter. Located 7200 light years away, the Wizard nebula, surrounds developing open star cluster NGC 7380. Visually, the interplay of stars, gas, and dust has created a shape that appears to some like a fictional medieval sorcerer. The active star forming region spans about 100 light years, making it appear larger than the angular extent of the Moon. The Wizard Nebula can be located with a small telescope toward the constellation of the King of Aethiopia (Cepheus). Although the nebula may last only a few million years, some of the stars being formed may outlive our Sun.

Cataloged as Sh2-239 and LDN 1551, the region lies near the southern end of the Taurus molecular cloud complex some 450 light-years distant. Stretching for nearly 3 light-years, the canvas abounds with signs of embedded young stellar objects driving dynamic outflows into the surrounding medium. Included near the center of the frame, a compact, tell-tale red jet of shocked hydrogen gas is near the position of infrared source IRS5, known to be a system of protostars surrounded by dust disks. Just below it are the broader, brighter wings of HH 102, one of the region's many Herbig-Haro objects, nebulosity's associated with newly born stars. Estimates indicate that the star forming LDN 1551 region contains a total amount of material equivalent to about 50 times the mass of the Sun.

Otherwise catalogued as NGC 2261 by the astronomer John Louis Emil Dreyer in 1888 in his iconic New General Catalogue, this nebula was discovered in 1783 by William Herschel. It is also famous for the being the first deep sky object to have been photographed with the Hale Telescope at the Palomar Observatory in 1949 by none other than Edwin Hubble. The popular name of this nebula arises from it being studied by Edwin Hubble in 1916 who noticed it changed in brightness. It is now known that its dramatic and quite quick changes in brightness and appearance are the result of opaque clouds of dust situated between the star and the nebula. The appearance of NGC 2261 has been observed to change on timescales of a few months if not a few days! The reddish nebulosity visible to the north of NGC 2261 is an example of a Herbig Haro object, a type of jet ejected by a young star that glows by the energy generated by the gas colliding with its surrounding space. They were originally independently discovered by the astronomers George Herbig and Guillermo Haro. This Herbig Haro object is catalogued as HH 39 and more than a thousand are currently known. An analysis of the proper motion of the knots in HH 39 show that it is moving away from R Monocerotis and NGC 2261." LRGBHa 300,180,180,180,450 Taken with a PlaneWave 24" CDK from Animas New Mexico. Thank you, Mark https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1544625807872-I7RU5OUV6WELHPMS60PE/IC348+Web-2apod.jpg Nebula - IC 348 - IC 1985 IC 348 (also known as IC 1985) is a 2 million year old open star cluster surrounded by a reflection nebula of about 15 light-years across, located some 1028 light-years away from Earth in the northern constellation of Perseus, while it is receding from us at 14 kilometers per second. It is embedded in the star-forming region called the Perseus molecular cloud. The light from the roughly 400 stars in the cluster is scattered by clouds of dust in the star-forming region, producing the reflection nebula. The cluster’s brightest members are hot, bright bluish Main Sequence stars, but some stars are still in the process of formation, so star formation is an ongoing process in the region. The most massive stars in the cluster are the stars of the binary star system called BD+31°643. About half of the stars in the cluster have a circumstellar disk, of which 60% are primordial disks, where planets could be forming. Studies of circumstellar disks in clusters of various ages are expected to yield a better understanding of the dynamics of planet formation. Inside this extremely young cluster are also about thirty brown dwarfs discovered, with masses as low as 15 to 80 times that of Jupiter, as well as three brown dwarfs with estimated masses of less than 10 times that of Jupiter. Brown dwarfs lose heat as they age, so they are more readily discovered while they are still young. Current models estimate that their surfaces are approximately 900-1000 degrees Kelvin (about 600-700 degrees Celsius). That’s extremely cool for objects that have just formed, which implies that they have the lowest masses of any of this type of object that we’ve seen to date. The discovery of the dwarfs in IC 348 has allowed astronomers to set new limits on the lowest mass objects. Recently, astronomers discovered an unusual variable object inside IC 348 that appears to be a close binary pair of protostars, named LRLL 54361 (L54361 for short). This bright object emits flashes of light every 25.34 days. These two protostars drag material inwards from a surrounding disk of gas and dust. The light flashes are probably due to this material suddenly being dumped onto the growing stars as they near one another in their orbits, unleashing a blast of radiation. This is only the third time this phenomenon has been observed, and it is the most powerful such beacon seen to date. It is also the first to be seen associated with a light echo. Flashing double star systems like this one are rare, because close binaries account for only a few percent of our galaxy’s stellar population. Moreover, the pulsing light is likely to be a brief phenomenon in the early life of a star. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1541627404075-AOHHAXRN3OKCAPQ59V1L/CTB1-Apodsmall2.jpg Nebula - CTB1-Supernova Remnant Spanning an area of 35 arcminutes on the sky towards the constellation of Cassiopeia, this enigmatic loop of ionized nebulosity is a supernova remnant catalogued as CTB 1. This name denotes it as a radio source compiled in the Caltech Observatory list B catalogue of 110 radio sources discovered in a radio survey in 1960. A few other CTB sources also correspond with a supernova remnant such as CTB 80. The radio source CTB 1 was suspected to be a supernova remnant in 1960 and confirmed as a supernova remnant in 1971. Optical emission associated with it was discovered by Sidney van den Bergh in 1973. The optical structure consists of a roughly circular shell with a breakout rupture towards the north, which also coincides with a break in the radio shell at this location. This is likely to be the result of the supernova remnant's interaction with a nearby cavity of neutral hydrogen gas. The Ha shell is composed of multiple interlocking limb brightened filaments with faint emission also extending beyond the main shell towards the south. The OIII structure consists of a series of filaments forming a curved arc towards one side. Close inspection also reveals a small dark globule silhouetted against the southern part. CTB 1 belongs to the morphological class of mixed-morphology supernova remnants, which consist of a radio shell with central x-ray emission. Other prominent examples of this class include IC 443 and W28. At a distance of 10,000 light years, the diameter of CTB 1 is 100 light years. The expansion of the shell in a highly dynamic environment suggests that the progenitor star that exploded to form the supernova remnant might have been a B or O-type supergiant star. The age of CTB 1 has many estimates but the most commonly accepted one is 10,000 years. Interestingly this object has been considered erroneously as a planetary nebula and is catalogued as Abell 85 in George Abell's second version of the Abell planetary nebula catalogue published in 1966 and was also included in the first version published in 1955. It is also wrongly catalogued as a HII region in Beverley Lynd's amusingly named 1965 catalogue of bright nebulae as LBN 576. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1542318641042-9FKP89BGM154DWWS2ZTJ/NGC654Websmall.jpg Nebula - NGC 654 &amp; The Dark Serpent Cassiopeia's Dark Serpent Image Credit & Copyright: Mark Hanson Description by Mark Hanson NGC 654 is a brilliant colorful open cluster in the constellation Cassiopeia.

Their gaseous forms are sculpted by the UV radiation and stellar winds from many hot young stars in the star cluster associated with the Soul Nebula. The term "bright rimmed" arises from the side of the globules that are facing the ionzing source exhibiting bright rims as a result of the gas and dust becoming more compressed and denser and therefore brighter than the surrounding material. In the case of IC 1871 and SFO 12, they point towards the cluster situated West of them (not visible in image).

The aptly named Pillars of Creation, featured in this stunning Hubble image, are part of an active star-forming region within the nebula and hide newborn stars in their wispy columns. Although this is not Hubble’s first image of this iconic feature of the Eagle Nebula, it is the most detailed. The blue colors in the image represent oxygen, red is sulfur, and green represents both nitrogen and hydrogen. The pillars are bathed in the scorching ultraviolet light from a cluster of young stars located just outside the frame. The winds from these stars are slowly eroding the towers of gas and dust. Stretching roughly 4 to 5 light-years, the Pillars of Creation are a fascinating but relatively small feature of the entire Eagle Nebula, which spans 70 by 55 light-years. The nebula, discovered in 1745 by the Swiss astronomer Jean-Philippe Loys de Chéseaux, is located 7,000 light-years from Earth in the constellation Serpens. With an apparent magnitude of 6, the Eagle Nebula can be spotted through a small telescope and is best viewed during July. A large telescope and optimal viewing conditions are necessary to resolve the Pillars of Creation. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1522852250081-B2IY3D3I7WH3G17VAT48/SH2-278APODsmall.jpg Nebula - SH2-278 From SWO SH2-278, Sharpless 278     "Billowing crimson waves of hydrogen gas cascade in an ocean of tranquility in this uncommon view of the rarely photographed emission nebula Sh2-278. Adding a ghostly presence to the proceedings are clouds of blue dust glowing by reflected starlight.   The most apparent component of this cosmic vista is the bright rimmed dark nebula LDN 1634 to the left of the image. Although small, but easily discernable, multiple red knots of nebulosity are visible near the center of LDN 1634. These constitute a flow of Herbig Haro objects, tiny jets launched by young protostars that glow by being collisionally excited.   The largest of these is known as RNO 40 and the RNO catalogue of 'red nebulous objects' was published by the astronomer Martin Cohen in 1980. The RNO 40 outflow is driven by a protostar called IRAS 05173-0555 and is also catalogued as HH 240.   Professional studies have concluded that Sh2-278 is either a remnant of the gas in the Orion Molecular Cloud that formed the Orion OB1 association or a cloud that was pushed to its current location by the winds and pressure of the OB association. In the sky, it is located north of Rigel."   https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1518643760441-I7EFB9YMLTFEUM0B7V1U/LBN670APODsmall.jpg Nebula - SFO 11 in the Soul Nebula (SWO) SFO 11,11NE,11E in LBN 670 You can see many of the bright rimmed globules clearly, these are the result of UV radiation and winds from hot young stars that have had an effect on the gas around them. Sometimes I wonder what the nebula the Sun was born in would have looked like? SFO stands for "Sugitani, Fukui and Ogura", the surnames of three Japanese astronomers who compiled the SFO catalogue of bright rimmed globules in HII regions. It was published in 1991 (northern hemisphere) and 1994 (southern hemisphere) by Koji Sugitani, Yasuo Fukui and Katsuo Ogura and has 89 in total. For no particular reason it isn't well known outside the professional community. Explanation from Sakib Razool Telescope: 24" Planewave, SBIG 16803, Planewave 200HR Location: Stellar Winds Observatory DSNM, Animas New Mexico LRGB/HA LRGB 300 min each, HA 840 min https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1518121959606-MA4ND75SL5NRK2YYJVQ6/RunningManfinalsmall.jpg Nebula - Running Man Nebula (SWO) Explanation: The 1970s are sometimes ignored by astronomers. In particular, this beautiful grouping of reflection nebulae in Orion - NGC 1977, NGC 1975, and NGC 1973 - are usually overlooked in favor of the substantial glow from the nearby stellar nursery better known as the Orion Nebula. Found along Orion's sword just north of the bright Orion Nebula complex, these reflection nebulae are also associated with Orion's giant molecular cloud about 1,500 light-years away, but are dominated by the characteristic blue color of interstellar dust reflecting light from hot young stars. North is down in this sharp color telescopic image from New South Wales, Australia, so the more familiar Orion Nebula borders the top of the view. NGC 1977 stretches across the field just above center, separated from NGC 1973 (below left) and NGC 1975 (below right) by darker regions of obscuring dust. Many northern hemisphere observers claim to see the general shape of a running man in the cosmic dust cloud but, of course, they're looking at the view upside down. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1517606679362-BYF7DL9L9BI96M12JETK/NGC+1999+ApodSmall.jpg Nebula - NGC 1999 (SWO) Explanation: South of the large star-forming region known as the Orion Nebula, lies bright blue reflection nebula NGC 1999. At the edge of the Orion molecular cloud complex some 1,500 light-years distant, NGC 1999's illumination is provided by the embedded variable star V380 Orionis. That nebula is marked with a dark sideways T-shape near center in this cosmic vista that spans about 10 light-years. The dark shape was once assumed to be an obscuring dust cloud seen in silhouette against the bright reflection nebula. But recent infrared images indicate the shape is likely a hole blown through the nebula itself by energetic young stars. In fact, this region abounds with energetic young stars producing jets and outflows with luminous shock waves. Cataloged as Herbig-Haro (HH) objects, named for astronomers George Herbig and Guillermo Haro, the shocks look like red gashes in this scene that includes HH1 and HH2 just below NGC 1999. The stellar jets push through the surrounding material at speeds of hundreds of kilometers per second. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1513913741610-ZY59C1XBHDLNOGLMMSG5/NGC+1579Apod.jpg Nebula - NGC 1579 (SWO) Explanation: Colorful NGC 1579 resembles the better known Trifid Nebula, but lies much farther north in planet Earth's sky, in the heroic constellation Perseus. About 2,100 light-years away and 3 light-years across, NGC 1579 is, like the Trifid, a study in contrasting blue and red colors, with dark dust lanes prominent in the nebula's central regions. In both, dust reflects starlight to produce beautiful blue reflection nebulae. But unlike the Trifid, in NGC 1579 the reddish glow is not emission from clouds of glowing hydrogen gas excited by ultraviolet light from a nearby hot star. Instead, the dust in NGC 1579 drastically diminishes, reddens, and scatters the light from an embedded, extremely young, massive star, itself a strong emitter of the characteristic red hydrogen alpha light. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1512581104759-I9HCCLQWNZP49PTN4RAZ/M15webApod.jpg Nebula https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1512581051700-AKKWG6S4S6J4WU2NRI8D/IC1805PillarCrop.jpg Nebula - IC 1805, Pillar of Creation (SWO) "The Lost Pillar of Creation"   Most know of the "Pillars of Creation,” which is a famous image from the Hubble Space Telescope, but few know of this hidden pillar. What a gem! This “no name” pillar is all alone in the dark shadows of the Heart and Soul Nebula. In between open cluster NGC 1024 and IC 1805, the pillar itself looks like a finger pointing to the wonderful Melotte 15 Nebula at the center of IC 1805. A beautiful, but quite faint object. It needs long Ha exposures to really make it pop out.   https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1512436843313-D1J8ZBVUD0KW1PB4SF55/LBN762FinishedCropedapod.jpg Nebula - LBN 762 (SWO) Although very photogenic and well placed for northern observers these two objects are rarely imaged: LBN 762 / MBM13 dubbed the Drunken Dragon Nebula can be seen in this image. This field is located in Aries just south of MBM12.This relatively young association of gas and dust is home to an early stellar nursery and a few newborn stars . Once believed to be the nearest dust cloud from our solar system it is now suggested to be about 850 light-years away.The structure of LBN 762 is quite amazing, one must wonder what forces are at play to create such intricate features. Numerous background galaxies are visible, some even through relatively dense part of the translucent clouds. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1509646043305-N4TQS2SEMPYWTLRSGE4S/IrisNebulaFinishedApodSmall.jpg Nebula - Iris Nebula-NGC 7023 (SWO) These cosmic clouds have blossomed 1,300 light-years away, in the fertile starfields of the constellation Cepheus. Called the Iris Nebula, NGC 7023 is not the only nebula to evoke the imagery of flowers, though. Still, this deep telescopic image shows off the Iris Nebula's range of colors and symmetries, embedded in surrounding fields of interstellar dust. Within the Iris itself, dusty nebular material surrounds a hot, young star. The dominant color of the brighter reflection nebula is blue, characteristic of dust grains reflecting starlight. Central filaments of the reflection nebula glow with a faint reddish photoluminesence as some dust grains effectively convert the star's invisible ultraviolet radiation to visible red light. Infrared observations indicate that this nebula contains complex carbon molecules known as PAHs. The pretty blue petals of the Iris Nebula span about six light-years. The colorful field-of-view stretches almost five Full Moons across the sky. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491960945026-P2CNTY3OJTRQ5CIEEX8L/Gum20finished4-6-17.jpg Nebula - Gum 20 from SSRO https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491434726953-MJB5TJQE388Y906XBWAN/VDB-38Finished.jpg Nebula - VDB 38 from Stellar Winds Observatory-DSNM https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491434683173-SWVWIL3TQW04E18D341U/NGC+2023+Final.jpg Nebula - NGC 2023 from SSRO in Cito, Chile https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491434742421-OVXHXJB9IB17UXEGKMT3/NGC346+FinishedNew.jpg Nebula - NGC 346 (SSRO Cito, Chile) https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491434704134-I5KOXR7OSDRQTYUST783/NGC281+Astronomymag.jpg Nebula - NGC 281 LRGB (SRO-California) https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491433472885-II2DUAZPVDPWH8TV1XZZ/IC50707filterWeb.jpg Nebula - IC 5067 The Pelican (Narrowband) https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491434670611-SP1DJU7QUQYO6VC3IUC5/281Narrow.jpg Nebula - NGC 281 Narrowband (SRO-California) https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491433453332-VWDV18TWWEZYTYGI10RI/IC5070LRGB.jpg Nebula - IC 5067 The Pelican https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491434704671-CUE6VHXP6G2HQ3350B9Z/BokGlobsAPYMarkHanson.jpg Nebula - NGC 2237 Bok Globules in the Rosette Nebula https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491433415983-JENFIV5C03CADQ567BOT/IC410+All.jpg Nebula - IC 410 The Tadpoles https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491433440147-4MQEMNHL81Q1F08HO2YL/IC1805+DOneweb.jpg Nebula - Melotte 15 (Rancho Hidalgo-DGRO) https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491433370841-BNWBQX66NH4TKGOHIRPI/APODNGC6823.jpg Nebula - NGC 6823 https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491433479482-NMWXI235STHQP7PRK2QK/LBN777FinalFlat.jpg Nebula - LBN 777 The Baby Eagle https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491433501871-FVLKQ8UTEILGT7SMO0RG/M17Web.jpg Nebula - M 17, The Swan or Omega Nebula https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491433552110-J7GJ9UR5C9GOP3RPQRQ6/M20MarkfinalWeblarge.jpg Nebula - M20, Trifid Nebula https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491433574682-1BENTABNTQK1R8ZWM9A1/NGC1333Web.jpg Nebula - NGC 1333 https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491433565287-5QLROA54U9GGBDLDWUDK/NGC1555+Finished10.jpg Nebula - NGC 1555, 1554 Hind's Variable Nebula https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491433508871-IIGKNTOO2SUGH4XI9N0D/LDN1622Final3.jpg Nebula - LDN 1622 Dark Nebula https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491433396543-RJFM3WVCQYQ1XVG4QHJX/CaveJPG.jpg Nebula - Cave Nebula, Caldwell 9, SH2-155 https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491433601851-GTJASTUSBOWGPC0K4OG7/TheWallFinal3Web.jpg Nebula - NGC 7000, The Wall https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491433622149-70SOVIL2MDI4TTRS4U5E/VDB143Web.jpg Nebula - VDB 142, Elephants Trunk Nebula https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491433383956-PRYKTFFQH6UKGJWTCPZN/Astronomyconefox.jpg Nebula - Cone and Fox Fur Nebula, NGC 2264 Cone and Fox Fur Nebula Mosaic Taken from DGRO Rancho Hidalgo Animas, New Mexico 14.5" RCOS F8, Apogee U16M High Cooling HA 390 min S2 330min O3 300min Red 135min Green 105min Blue 135min Calibrated,combined in CCD Stack all other processing done using PS5.

This image here includes the entire outer shell and is the only image of this I could find. The outer structures around this planetary nebula were discovered by the Galactic Planetary Nebula Halo Survey (GPNHS) team in May 2016. This planetary nebula represents a fleeting, poetic moment in the life cycle of a star similar to our own Sun. As the central star reached the end of its nuclear fuel, it gently shed its outer layers into the cold vacuum of space, creating a shimmering, translucent shell of ionized gas. Unlike the violent cataclysms of supernovae, this expansion is a graceful transition, where the exposed, scorching-hot core—a fledgling white dwarf—floods the surrounding nebula with ultraviolet light, causing it to glow with a soft, ethereal radiance. Visually, Longmore 8 is a testament to the intricate symmetry found in the cosmos. Often appearing as a faint, circular, or slightly elliptical smudge against the dense star fields of the Milky Way, its subtle structure reveals the complex interplay between stellar winds and magnetic fields. Because it is relatively low in surface brightness, it remains a hidden gem, typically reserved for the long-exposure eyes of large telescopes rather than a casual glance. To study this nebula is to look into the far-distant future of our own solar system, capturing a final, beautiful exhale of a star before it fades into the dark permanence of a stellar remnant.

Its vibrant display of colors—yellow for sulfur, red for hydrogen, and blue oxygen—maps out the last emissions of a star as it sheds its outer layers. These elements enrich the nearby interstellar space, providing material that may form new stars and planets in the future. Situated about 3,000 light-years away within the constellation Musca, NGC 5189 has earned the name Spiral Planetary Nebula due to its dramatic, complex swirls of luminous gas. Unlike the typical bubble-shaped envelopes seen around dying stars, this nebula presents a chaotic landscape filled with twisted strands and knots spanning distances similar to our solar system. The nebula’s distinctive shape results from the gravitational interplay between the two central stars: a hot Wolf-Rayet star—the exposed core of a faltering sun—and its companion, a compact white dwarf. With an orbital period of just a few days, their interaction produces shifting axes reminiscent of a spinning lawn sprinkler, ejecting material outward in various directions. This phenomenon, called precession, sculpts the unique, symmetrical lobes that give NGC 5189 its spiral, galaxy-like appearance. Imaged in RGBHa on a Planewave CDK 24 at Observatorio El Sauce, Chile.

Thousands of comet-Like filaments likely formed when hot stellar winds and radiation plowed into colder shells of gas and dust. Some stars die slowly, giving off puffs of gas and dust known as planetary nebulas to reveal small white dwarfs. Much larger stars die suddenly in powerful explosions known as supernovas, blasting gas, dust, and energy out in all directions as they collapse to form tiny neutron stars or black holes. The gas and dust expelled by dying stars eventually combines with the remains of others to form new stars, planets, and moons. As the dying star at the center of the Helix Nebula exhausted its fuel, it threw off its outer layers as a gaseous wind and transformed into a white dwarf. As the glowing shells of gas expand over 10,000 years, they eventually thin out and become part of the interstellar medium. Planetary nebulas provide a snapshot of a transitional phase in the life and death of a star.

NGC 2867 (also known as Caldwell 90) is an elliptical Type II planetary nebula in the southern constellation of Carina, just over a degree to the NNW of the star Iota Carinae. John Herschel discovered the discovery on April 1, 1834. Herschel initially thought he might have found a new planet, but on the following night he checked again and discovered it had not moved. The nebula is located 7,270 light-years from the Sun. Caldwell 90 was formed in the late stages of the development of a Sun-like star. Following the nuclear fusion of hydrogen into helium in its core, the star underwent a series of energy crises when its supply of hydrogen began to decline. Without the outward force previously created by the energy production, gravity shifted and caused the star's core to contract. The extra pressure allowed the star to produce a heavier substance in its core. The synthesis of carbon produced a lot more energy than the fusion of hydrogen into helium, which enabled the star to not only overcome gravity to expand once more but led the star to become a red giant. Eventually the red giant’s outer layers of gas were ejected. Meanwhile, the star transformed from a cool giant into a hot, dense star that radiates ultraviolet light and a fast wind of particles that move outward at around 6 million miles per hour. The stellar wind and ultraviolet light interact with the layers of gas that the red giant ejected to create the glowing, spherical shell we see today.

It is moving away from us at 49 kilometers per second. Despite their name, planetary nebulae have nothing to do with planets. The name of planetary nebulae arose because of the visual similarity between some round planetary nebulae and the planets Uranus and Neptune when viewed through early telescopes. When a star with a mass up to eight times that of the Sun approaches the end of its life, it blows off its outer shells and begins to lose mass. This allows the hot, inner core of the star to radiate strongly, causing this outward-moving cocoon of gas to glow brightly as a planetary nebula. Over the next several thousand years, the nebula will gradually disperse into space, and then the star will cool and fade away for billions of years as a white dwarf. Our own Sun is expected to undergo a similar fate, but fortunately this will not occur until some 5 billion years from now. There are two stars close together — a binary system — in the center of NGC 3132, one of 10th magnitude, the other 16th. It’s the dim star, not the bright one, near the center that caused multiple outbursts and originated the intricate, somewhat concentric structure of the nebula. This hot central star is a white dwarf of about 100,000 K that has now blown off its layers and is making the nebula fluoresce brightly from the emission of its intense ultraviolet radiation. This expanding cloud of gas is one of the nearest known planetary nebulae. The gases are expanding away from the central star at a speed of about 14.4 kilometers per second. Neither the unusual shape of the surrounding cooler shell nor the structure and placements of the cool filamentary dust lanes running across NGC 3132 are well understood. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1698192355676-OW61K5XRND3632F1FU3P/image-asset.jpeg Planetary Nebula - M46 & Planetary Nebula NGC 2438 M46 & Planetary Nebula NGC 2438 Messier 46 or M46, also known as NGC 2437, is an open cluster of stars in the slightly southern constellation of Puppis. It was discovered by Charles Messier in 1771. Dreyer described it as "very bright, very rich, very large." It is about 5,000 light-years away. There are an estimated 500 stars in the Cluster. NGC 2438 is a planetary nebula (Left Center) The central star is roughly 1,370 light years. So closer than M46 cluster. This is a multi-shell planetary nebula with a bright inner nebula consisting of two somewhat detached shells. The structure is surrounded by a fainter, mostly circular halo. The nebula consists of material ejected from the central star. The main nebula was formed at about half that age. The central star of this planetary nebula is one of the hottest stars known.

Type I (helium and nitrogen rich) planetary nebula by Peimbert classification [5], He 2-111 has a planar bipolar asymmetrical shape, which is found to be likely shaped by a triple stellar system in [3, 4]. With estimated distance to the nebula of about 6.8 kly [1-2] and long axis angular length of about 10’ the diameter if the “lobes” corresponds to about 20 ly and the long axis of the core of the nebular of about 30” corresponds to about 1 ly. Thus, the nebula lies much further away than HD 127470 star (830 ly away) - the brightest star in the frame above the core of He 2-111, but roughly at the same distance as a nearby NGC 5617 open cluster (6.5 kly). The central star (or rather central stars) of this nebula have never been observed, but its core reveals a complex structure featuring a toroid placed at about 45 deg inclination to the plane of the “lobes”, with the outer diameter along the major axis of 20” and inner diameter along the same axis of 14” or 0.7 ly and 0.5 ly of linear size correspondingly, based on the best available distance estimates from above. This toroidal structure in the core turned out to be best visible in the SII channel, and adding it to the exposure set allowed to boost visibility of fine details in the core compared to HO(L)RGB images of this object obtained earlier. Two sets of “spokes” are reaching out from the core of the nebula to the periphery which consists of fast moving radially extended “knots” of material for which the radial velocity is found to be reaching 650 km/s which put the age of the nebula in the range of 8-20 ky depending on the model of the expansion [1, 2]. A peculiar cusp-like structure is visible next to one of the “spokes” on the left from the core, revealed in a fully connected way in this image, likely for the first time. Extended diffuse structures visible on the outer side of the lobes of the nebula (best visible in the starless version of the image) - also likely for the first time.

At that time, Charles Messier was compiling a list of diffuse objects not to be confused with comets. The 27th object on Messier's list, now known as M27 or the Dumbbell Nebula, is a planetary nebula, the type of nebula our Sun will produce when nuclear fusion stops in its core. M27 is one of the brightest planetary nebulae in the sky, and can be seen toward the constellation of the Fox (Vulpecula) with binoculars. It takes light about 1000 years to reach us from M27. Understanding the physics and significance of M27 was well beyond 18th century science. Even today, many things remain mysterious about bipolar planetary nebula like M27, including the physical mechanism that expels a low-mass star's gaseous outer-envelope, leaving an X-ray hot white dwarf.

Surrounded by Milky Way stars and near the line-of-sight to distant background galaxies, its generally simple spherical shape, about 8 light-years in diameter, is outlined in this deep telescopic image. Within its confines are beautiful, more complex details enhanced using narrowband filters. Emission from hydrogen and nitrogen is shown in reddish hues with oxygen emission mapped to a bluish-green color, giving Abell 7 a more natural appearance that would otherwise be much too faint to be appreciated by eye. A planetary nebula represents a very brief final phase in stellar evolution that our own Sun will experience 5 billion years hence, as the nebula's central, once sun-like star shrugs off its outer layers. Abell 7 itself is estimated to be 20,000 years old. Its central star is seen here as a fading white dwarf some 10 billion years old. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1640463907923-77DT83MDASM7JDC1M1Z0/image-asset.jpeg Planetary Nebula - NGC 1360 The Robin's Egg Nebula This pretty cosmic cloud lies some 1,500 light-years away, it shape and color reminiscent of a blue robin's egg. It spans about 3 light-years, nested securely within the boundaries of the southern constellation Fornax. Recognized as a planetary nebula, NGC 1360 doesn't represent a beginning though. Instead, it corresponds to a brief and final phase in the evolution of an aging star. In fact, visible in the telescopic image the central star of NGC 1360 is known to be a binary star system likely consisting of two evolved white dwarf stars, less massive but much hotter than the Sun. Their intense and otherwise invisible ultraviolet radiation has stripped away electrons from the atoms in the surrounding gaseous shroud. The predominant blue-green hue of NGC 1360 seen here is the strong emission produced as electrons recombine with doubly ionized oxygen atoms. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1584101808943-ZWP2HP7429FUC6FOG4IC/SH2-200Thumb.jpg Planetary Nebula - HDW 2 (Sh2-200) HDW 2 (Sh2-200): This exquisitely detailed image is a portrait of the planetary nebula HDW 2, which is located towards the royal constellation of Cassiopeia. Consisting of iridescent shades of purple and blue, this ethereal bubble represents the ghostly remains of a dying star. The category of planetary nebulae was given its name due to telescopic observations by 18th century astronomers such as William Herschel and others being described as similar in appearance and brightness to planets. In astronomy, many things are named after their resemblance to something. HDW 2 is a very faint ancient planetary nebula of low surface brightness, therefore making telescopic observations very difficult. Faint planetary nebulae such as this one are best appreciated in detailed astrophotographs such as this one and even then, long exposures of many hours are still required. Whilst in the past planetary nebulae might have been discovered through direct visual observations, the many discoveries made in the 21st century have been through photographic means. Some discoveries have been made by professionals as part of large scale surveys such as the Ear Nebula and some discoveries have been due to amateur astrophotographers such as the Soap Bubble Nebula. This nebula was first discovered by the astronomer Stewart Sharpless in 1959 who included it in his catalogue of HII regions under the name of Sh2-200. His catalogue was compiled after analysing photographic plates taken at the Palomar Observatory. The misidentification of HDW 2 (or Sh2-200) arose from the criteria of assembling the catalogue, which compared the separate red and blue photographic plates of the same region. If a nebula was more prominently visible on the red plate, it was deduced that it was more likely to be an ionized nebula. The other criteria was the presence of bright stars in the vicinity, which might be the source of ionization. Despite increasing the number of catalogued and known deep sky objects, the method of analysing monochromatic photographic plates displayed its limitation with the incorrect classification of nebulae with a number of entries in the Sharpless catalogue of HII regions subsequently being found to belong to different categories of objects such as planetary nebulae, supernova remnants, Wolf Rayet nebulae, high latitude dust clouds and even galaxies. In 1983, Sh2-200 was included in the HDW catalogue of possible planetary nebulae by the astronomers Herbert Hartl, Johann Dengel and Ronald Weinberger. However it wasn't confirmed to be a true genuine planetary nebula until 2017 when spectra was taken as part of professional observations. In 1987, further narrowband observations by Herbert Hartl and Ronald Weinberger detected a large faint outer halo extending further than the central shell. A feature not fully appreciated or clearly defined in the scientific literature is something known as ISM-type haloes. These are a type of structure that represent ambient interstellar gas in the vicinity of the planetary nebula but not physically related to it. Despite being very old and highly evolved, low surface brightness planetary nebulae such as HDW 2 contain very hot and energetic central stars, which are the remnant cores of the progenitor star that died and ejected its outer gaseous layers. The energy output of some planetary nebula central stars is so prodigious that it is capable of ionizing unrelated gas in the surrounding vicinity causing it to glow. The most popular example of this phenomenon is the large halo around NGC 3242. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1581115562802-3V611NW0YYUUWM56ZB46/A8Crop.jpg Planetary Nebula - Abell 8 Abell 8 is a 1 arcminute planetary nebula consisting of a Ha bright rim and an OIII interior. Deep narrowband images such as this one show extended clouds of hydrogen in the vicinity. This isn't material ejected by the progenitor star but ambient material in the surrounding interstellar medium (ISM) that is being ionized by ultraviolet radiation of the central star leaking out of the thin gaseous shell of the planetary nebula. Abell 8 was discovered by the astronomer George Abell in 1955. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1572439424938-422ZBC97R73GV48O6TR0/Abell78-4Crop.jpg Planetary Nebula - Abell-78 Abell 78 This planetary nebula has the unusual property of having a faint outer halo composed of normal stellar material (mostly hydrogen) and a bright inner elliptical ring composed mostly of helium. The helium ring provides direct confirmation that hydrogen is being converted to helium in the centers of stars and can later be ejected back into the galaxy's pool of gas for building another generation of enriched stars.

Astronomers have modeled the three-dimensional structure of the nebula, finding it to be a cloud shaped as an irregular ellipsoid filled with bumpy and bubbly regions. It has a bright central star that can be seen easily in this image, shining brightly from within the nebula’s cloud. This bright pearl embedded within its glowing shell inspired the nebula’s popular nickname: the Oyster Nebula. While NGC 1501's central star blasted off its outer shell long ago, it still remains very hot and luminous, although it is quite tricky for observers to spot through modest telescopes. This star has actually been the subject of many studies by astronomers due to one very unusual feature: it seems to be pulsating, varying quite significantly in brightness over a typical timescale of just half an hour. While variable stars are not unusual, it is uncommon to find one at the heart of a planetary nebula. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1551406760774-FBMG64F2D3Y42G8XC7NI/M76100crop.jpg Planetary Nebula - M76 Explanation: "Nebula at the right foot of Andromeda ... " begins the description for the 76th object in Charles Messier's 18th century Catalog of Nebulae and Star Clusters. In fact, M76 is one of the fainter objects on the Messier list and is also known by the popular name of the "Little Dumbbell Nebula". Like its brighter namesake M27 (the Dumbbell Nebula), M76 is recognized as a planetary nebula - a gaseous shroud cast off by a dying sunlike star. The nebula itself is thought to be shaped more like a donut, while the box-like appearance of its brighter central region is due to our nearly edge-on view. Gas expanding more rapidly away from the donut hole produces the fainter loops of far flung material. The fainter material is emphasized in this composite image, highlighted by showing emission from hydrogen atoms in orange and oxygen atoms in complementary blue hues. The nebula's dying star can be picked out in the sharp false-color image as the blue-tinted star near the center of the box-like shape. Distance estimates place M76 about 3 to 5 thousand light-years away, making the nebula over a light-year in diameter. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1548344099920-UAFOROK15MVFS7SMYE7K/100%25CropBubble.jpg Planetary Nebula - Bubble Nebula - NGC 7635 From GBO NGC 7635, also known as the Bubble Nebula, Sharpless 162, or Caldwell 11, is a H II region[1] emission nebula in the constellation Cassiopeia. It lies close to the direction of the open cluster Messier 52. The "bubble" is created by the stellar wind from a massive hot, 8.7[1] magnitude young central star, SAO 20575 (BD+60°2522).[7] The nebula is near a giant molecular cloud which contains the expansion of the bubble nebula while itself being excited by the hot central star, causing it to glow.[7] It was discovered in 1787 by William Herschel.[5] The star BD+60°2522 is thought to have a mass of about 44 M☉. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1545934007483-3WTZHLD6LLU82AQW2PKJ/NGC40FullCrop.jpg Planetary Nebula - NGC 40-CTA1 "NGC 40 is a bright planetary nebula consisting of a detailed core with an outer halo. This halo consists of a double structure with a diffuse inner halo attached to the central shell and a more irregular filamentary structure, which extends to the north. In addition to these array of features is a structure to the south, which has been interpreted as a jet. Professional observations with the Spitzer infrared telescope have shown the inner halo to consist of multiple overlapping radial spoke ring structures. This halo was discovered in 1987. The central star of this planetary nebula has been well studied by professional astronomers and is also interesting in its own right. It belongs to the Wolf Rayet subclass of planetary nebula central stars that are hydrogen deficient and exhibit high mass loss rates and strong stellar winds. WR type central stars have been identified in a number of other planetary nebulae including IC 4663 and Abell 48. Extending along the contours of the full field of this image are multiple colourful filaments belonging to the large faint supernova remnant CTA 1, which covers an area of 1.5 degrees across the sky. Both NGC 40 and CTA 1 are physically unrelated with the supernova remnant lying more distant in the background. NGC 40 is 3500 light years away and CTA 1 is 4500 light years away." https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1528984744235-HODZRP8CX5TIPQJNYFMM/Cats+Eye+Nebula+Crop.jpg Planetary Nebula - Cats Eye Nebula (SWO) Explanation: The Cat's Eye Nebula (NGC 6543) is one of the best known planetary nebulae in the sky. Its more familiar outlines are seen in the brighter central region of the nebula in this impressive wide-angle view. But the composite image combines many short and long exposures to also reveal an extremely faint outer halo. At an estimated distance of 3,000 light-years, the faint outer halo is over 5 light-years across. Planetary nebulae have long been appreciated as a final phase in the life of a sun-like star. More recently, some planetary nebulae are found to have halos like this one, likely formed of material shrugged off during earlier episodes in the star's evolution. While the planetary nebula phase is thought to last for around 10,000 years, astronomers estimate the age of the outer filamentary portions of this halo to be 50,000 to 90,000 years. Visible on the left, some 50 million light-years beyond the watchful planetary nebula, lies spiral galaxy NGC 6552. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1521493735586-ND5TGFE9UAYXP0NYMUIP/Cava1Aopdsmall.jpg Planetary Nebula - CaVa 1 Planetary Nebula (SWO) "CaVa 1 is an obscure ancient planetary nebula that was discovered by the French amateur astronomers Jean-Paul Cales and Michael Vanhuysse in 2017. It has a size of 8x7 arcminutes and is located in a region of background nebulosity. There is sometimes a relation between the size of a planetary nebula, its age and its relative faintness. Older planetary nebulae over time eventually expand more and the ionizing energy is spread over a larger area as well as the density of the gas being thinner, so therefore exhibit lower surface brightness. This is easily overcome by amateur astronomers who are able to obtain very long exposures. Large low surface brightness planetary nebulae have been discovered in professional Ha surveys and also by amateurs analysing various astronomical survey data.   CaVa 1 consists of primarily Ha emission with some OIII in its interior. The southern part exhibits a tenuous bowshock structure produced by its interaction with the surrounding interstellar medium (ISM). Few examples of planetary nebulae with ISM interaction are known due to their extremely low intrinsic brightness. This stage in the evolution of a planetary nebula precedes the total dilution and fading of a planetary nebula. However, the phenomenon of ISM interaction has been observed in young planetary nebulae with high speed central stars and studies conclude that different stages of interaction are exhibited throughout the life of planetary nebulae. The idea of a planetary nebula interacting with the ISM as it moves through space was proposed in 1969 by the Armenian astronomer Grigor Gurzadyan." https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1515010604180-OXIGA74V95TX04YF31LY/PuWe1O3ACrop.jpg Planetary Nebula - PuWe1 (PNG 158.9 + 17.8), in Lynx (SWO) PuWe1 (PNG 158.9 + 17.8), in Lynx, is one of the largest PN, that has an apparent diameter of 20'. It has been discovered by Purgathofer & Weinberger in 1980 on a Palomar sky survey print. As almost all this kind of old diluted PN, it is very faint and requires long exposures to get details. The Halpha signal is the strongest and draws a ring with several details in the structure while the OIII signal is extremely faint with a disc shape and no visible structure. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1512137021193-MJ8QM9OTWMOD5G181HJT/PK164%2B31HALRGBO3centercrop.jpg Planetary Nebula - PK 164+31.1 Jones-Emberson 1 (SWO) PK 164+31.1 Jones-Emberson 1 Explanation APOD: Is this what will become of our Sun? Quite possibly. The bubble of expanding gas pictured above is the planetary nebula PK 164 +31.1, the remnants of the atmosphere of a Sun-like star expelled as its supply of fusion-able core hydrogen became depleted. Visible near the center of the nebula is what remains of the core itself -- a blue-hot white dwarf star. This particularly photogenic planetary nebula shows intricate shells of gas likely expelled at different times toward the end the star's demise, and whose structure is not fully understood. This deep image of PK 164 +31.1 shows many other stars from our own Milky Way Galaxy as well as several galaxies far in the distance. PK 164 +31, also known as Jones-Emberson 1, lies about 1,600 light years away toward the constellation of the Wildcat (Lynx). Due to its faintness (magnitude 17) and low surface brightness, the object is only visible with a good-sized telescope. Although the expanding nebula will fade away over the next few thousand years, the central white dwarf may well survive for billions of years -- to when our universe may be a very different place.

It was spectroscopically confirmed as a true planetary nebula by the professional astronomer Laurence Sabin in September 2011. It has also been independently discovered by the French amateur astronomer Laurent Ferrero in 2013 and is also known as Fe 6. Its structure consists of a low surface brightness bubble with a size of 3.5 arcminutes, which is accentuated by a thin "bright" rim on the outside. It is very likely to be an ancient evolved planetary nebula that is interacting with the interstellar medium (ISM) and its intensely blue central star is easily visible near the centre. Despite its faintness, it is possible to visually observe it in very large telescopes. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1506974085774-1HYXVZRA1TNWHZ169IIG/SoapBubbleAPODCrop.jpg Planetary Nebula - The Soap Bubble Nebula PN G75.5+1.7 (SWO) The Soap Bubble Nebula PN G75.5+1.7   Explanation From APOD: Adrift in the rich star fields of the constellation Cygnus, this lovely, symmetric nebula was only recognized a few years ago and does not yet appear in some astronomical catalogs. In fact, amateur astronomer Dave Jurasevich identified it as a nebula on 2008 July 6 in his images of the complex Cygnus region that included the Crescent Nebula (NGC 6888). He subsequently notified the International Astronomical Union. Only eleven days later the same object was independently identified by Mel Helm at Sierra Remote Observatories, imaged by Keith Quattrocchi and Helm, and also submitted to the IAU as a potentially unknown nebula. The nebula s now known as the Soap Bubble Nebula. Most probably it is a planetary nebula, a final phase in the life of a sun-like star. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1503853597434-EJFI8Z6LVEITH2O3ZWPL/M57LRGBHAThumb.jpg Planetary Nebula - M57 The Ring Nebula (SWO) The Ring Nebula (also catalogued as Messier 57, M57 or NGC 6720) is a planetary nebula in the northern constellation of Lyra.

There are several interesting features. The galaxy contains a massive black hole 140 million times greater than our sun. The black hole is surrounded by a ring replete with new star formation. The ring is lit by an influx of material moving towards the central bar of the galaxy. The galaxy contains four optical jets (one of which is extremely faint) that seem to emanate from the nucleus region. Studies have determined the jets are not emissions but are made up of stars. There are two satellite galaxies, NGC 1097 A and B. A is a peculiar galaxy which is orbiting only 42000 light years from the center of NGC 1097 while B is a dwarf galaxy which was discovered by emissions and has not been well studied.

Recognized as one of the brightest radio sources, NGC 1316 exhibits visual evidence of having originated from mergers involving gas-rich spiral galaxies roughly three billion years ago. Ripples, Loops, and Arcs: Faint, extensive shells and ripples comprising stars and gas are observable in the galaxy’s outer regions, indicating tidal disruptions characteristic of previous merger events. Dust Lanes: The presence of complex and pronounced dark dust lanes represents remnants of gas and dust acquired from the integrated spiral galaxies. Globular Clusters: Studies of the surrounding globular cluster system further substantiate this history. Astronomers have identified fewer low-mass clusters near the center—where destructive collisions would occur—as well as an abundance of atypical young, metal-rich clusters formed during starburst episodes initiated by the merger. In summary, NGC 1316 serves as an instructive model for the formation of giant elliptical galaxies through sequential mergers with smaller, gas-rich systems over extensive cosmic timescales. These merger events likely fueled its central black hole, leading to its radio-galaxy activity.

This remarkable image highlights a structure reminiscent of octopus arms, with its extensions radiating in multiple directions. The overall appearance is both impressive and visually distinctive. NGC 1672 exemplifies a barred spiral galaxy, which is distinct from typical spiral galaxies in that its spiral arms do not extend continuously into the galactic center. Rather, these arms are anchored to both ends of a linear stellar bar encircling the nucleus. Multiple ionized hydrogen regions are also discernible.

Along with its neighbor NGC 300, it is one of the closest galaxies to the Local Group, probably lying between the Milky Way and the Sculptor Group. It is likely that NGC 55 and its neighbor NGC 300 orbit each other and form a gravitationally bound pair. Along with NGC 300, NGC 55 is part of the Local Group of Galaxies that also includes the Andromeda galaxy (M31), the Large and Small Magellanic Clouds, and 40 other galaxies. NGC 55 is nearly edge-on and appears asymmetrical, like a cigar. Its bulge is diffuse, broad, and somewhat elongated. The bright core is crossed with clouds of gas and dust, and it has a lot of pinkish active star forming regions, and young blue star clusters. Among all these stars are over a hundred Cepheid Variables. NGC 55 is thought to be like our galactic neighbor, the Large Magellanic Cloud (LMC), although the LMC is seen face-on, whilst NGC 55 is edge-on.

NGC 5248 is a prominent spiral galaxy located within the constellation Boötes. Positioned approximately 50 million light-years from Earth, it is considered relatively close in astronomical terms. One of the notable features of NGC 5248 is the presence of a large ring of gas and dust surrounding the central bulge. This ring, known as a "pseudo-ring," is believed to have formed due to gravitational interaction between NGC 5248 and another nearby galaxy. The pseudo-ring is an active site of star formation, where many new stars are being created. NGC 5248 also contains a supermassive black hole at its center, estimated to have a mass of around 300 million times that of our Sun. This black hole is surrounded by a disk of gas and dust, which emits radiation as the material spirals toward the black hole. Spiral galaxies like NGC 5248 are significant for understanding cosmic formation and evolution. They are believed to originate from the mergers and interactions of smaller galaxies, and their study provides vital information on the mechanisms driving galactic development and the broader processes shaping the universe.

One notable instance here is revealed an intricate galactic portrait despite the presence of excessive satellite trails. NGC 5364, positioned in the left center, is a spiral galaxy situated within the constellation Virgo. It features distinctive swirling arms and a luminous core, categorizing it as a grand design spiral galaxy. Grand design spiral galaxies are characterized by their prominent, well-defined arms that extend outward from a distinct core. This classification is rare, with only ten percent of spiral galaxies fitting this category. NGC 5364 exhibits some asymmetrical in its arms compared to other grand design spirals. This irregularity is likely a result of interactions with the nearby lenticular galaxy NGC 5363, located at the right center. Known colloquially as "The Alligator's Eye", is distinguished by its dust lanes and is approximately 63 million light years away. NGC 5364 is approximately 67 million light years distant, while NGC 5360, another lenticular galaxy situated at the lower left, is around 64 million light years away.

The galaxy is highly unusual. It is a highly disturbed galaxy that was initially thought to be a lenticular galaxy but is now considered to likely be a spiral galaxy due to the faint arm extensions that are apparent in the image. There are however certain characteristics that are like a polar ring galaxy. If that wasn’t enough the twisted shape is certainly due to interactions with NGC 3729.

Extracting the magnificent Ha emission of this wonderful galaxy which is hidden due to the significant obscuration by these stars. I aimed to highlight the HA in this image. It was challenging to reveal, but it was worth the effort. NGC 3109 is classified as a Magellanic type irregular galaxy around 4.5 million light years from Earth, but it may be a small spiral galaxy. If it is a spiral galaxy, it would be the smallest in the Local Group. NGC 3109 has a mass of about 2.3×10 ^9 times the mass of our Sun, of which 20% is in the form of neutral hydrogen. The galaxy is oriented edge-on from our point of view, and but may contain a disk and a halo. The disk appears to be composed of stars of all ages, whereas the halo contains only very old and metal-poor stars. There is no sign of galactic nucleus. From measurements of the neutral atomic hydrogen in the galaxy, it has been found that the disk of NGC 3109 is warped. The warp has the same radial velocity as gas in the Antlia Dwarf galaxy, Astronomers believe that the two galaxies had a close encounter around one billion years ago.

It is 45 million light years from Earth, which, given its apparent dimensions, means that it’s about 70,000 light years across. The structure includes two highly diffuse, thick, and irregular spiral arms originating from the bulge, accompanied by additional fragmented spiral arms. Dark dust lanes cross the spiral pattern. The bulge looks elliptical and weak. At the galaxy's center is a supermassive black hole. Originally classified as a type 1 Seyfert galaxy, this galaxy has been reclassified as an HII region galaxy due to its narrow emission lines. NGC 3511 forms a pair with NGC 3513 which is a barred spiral galaxy which lies 10.5 arcminutes away. NGC 3513(bottom right) is a barred galaxy with a thin high-surface-brightness bar. The bar ends feature two distinct spiral arms with star formation knots and HII regions, creating a patchy appearance. The two galaxies form a small group, known as the NGC 3511 group, which also includes the galaxy ESO 502-024. A faint, narrow hydrogen bridge appears to connect the two galaxies.

IC 1613 (Caldwell 51) is a dwarf irregular galaxy located in the constellation Cetus and was discovered by Max Wolf in 1906. This galaxy is a member of the Local Group of galaxies and has a morphological classification of IBm (Irregular Barred - Magellanic type). Irregular galaxies are those that don't fit into the Hubble sequence of galaxy classification and often have chaotic structure, lack spiral arms and no nuclear bulge. It's believed that these galaxies are shaped so because of gravitational influences from passing galaxies or larger neighboring ones. IC1613 has a very low surface brightness and so little dust that background galaxies can been seen behind it in this image. The center has a visible bar like structure and overall has several star forming regions as evident by the red HIII regions surrounding hot blue O/B stars. Star ages range from 20 million to 10 billion years old. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1730496762520-52NLCBG1LXAVKHDQMB94/M61APODCrop.jpg Galaxies - Messier 61 (NGC 4303) SSRO Messier 61 (also known as NGC 4303) is a very bright barred spiral galaxy of some 100,000 light-years across, located only about 52.5 million light-years away from Earth in the constellation of Virgo (the Virgin), while it is receding from us at about 1566 kilometers per second. This grand design galaxy spiral (a spiral galaxy with prominent and well-defined spiral arms that extend clearly around the galaxy) is one of the largest members of the Virgo Cluster, a cluster of approximately 1300 (and possibly up to 2000) galaxies held together by gravity. This cluster forms the central region of the Virgo Supercluster (or Local Supercluster), an even bigger gathering of galaxies. Messier 61 is classified as a starburst galaxy and has an Active Galactic Nucleus. The energy source of an Active Galactic Nucleus is believed to originate in mass accretion by a supermassive black hole within the nucleus of the galaxy. Messier 61 probably has a supermassive black hole with a mass around 5 million times that of our Sun on its center. In this image, its spiral arms can be seen in stunning detail, swirling inwards to the very center of the galaxy, where they form a smaller, intensely bright spiral. In the outer regions, these vast arms are sprinkled with bright blue regions where new stars are being formed from hot, dense clouds of gas. The high star formation across Messier 61’s disk is perhaps due to interactions with her satellite galaxies NGC 4292 and NGC 4303B. The intensely bright spiral is a nuclear starburst ring some 730 light years from the nucleus, formed by several massive star-forming regions which contain massive hot stars with an age range between 5 and 25 million years old. The starburst ring may be associated with a second bar much smaller than the main one of this galaxy. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1730495904205-ZXNI4EDYV751YHLGBW9D/image-asset.jpeg Galaxies - NGC 488 NGC 488 is a spiral galaxy seen face on 90 million light years away in Pisces.

The grand spiral galaxy can be found toward the northern constellation of the Great Bear (Ursa Major). This superbly detailed image reveals M81's bright yellow nucleus, blue spiral arms, tell tale pinkish star forming regions, and sweeping cosmic dust lanes with a scale comparable to the Milky Way. Hinting at a disorderly past, a remarkable dust lane actually runs straight through the disk, to the left of the galactic center, contrary to M81's other prominent spiral features. The errant dust lane may be the lingering result of a close encounter between between M81 and its smaller companion galaxy, M82. Scrutiny of variable stars in M81 has yielded one of the best determined distances for an external galaxy -- 11.8 million light-years. M81's dwarf companion galaxy Holmberg IX can be seen just above the large spiral. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1493921425269-GGVY1MYELD1IMBXTOGHX/M51-CropDoneHA.jpg Galaxies - M51 With HA added https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1722805317875-N9AD82ZB0XCAYHMQXDL4/100%25CropNGC660.jpg Galaxies - NGC 660 - The Polar Ring Galaxy Explanation APOD: NGC 660 is featured in this cosmic snapshot. Over 40 million light-years away and swimming within the boundaries of the constellation Pisces, NGC 660's peculiar appearance marks it as a polar ring galaxy. A rare galaxy type, polar ring galaxies have a substantial population of stars, gas, and dust orbiting in rings strongly tilted from the plane of the galactic disk. The bizarre-looking configuration could have been caused by the chance capture of material from a passing galaxy by a disk galaxy, with the captured debris eventually strung out in a rotating ring. The violent gravitational interaction would account for the myriad pinkish star forming regions scattered along NGC 660's ring. The polar ring component can also be used to explore the shape of the galaxy's otherwise unseen dark matter halo by calculating the dark matter's gravitational influence on the rotation of the ring and disk. Broader than the disk, NGC 660's ring spans over 50,000 light-years. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1720533099365-7SQXJTPRY8UWVUMRF2NV/image-asset.jpeg Galaxies - NGC 3981 NGC 3981 is about 65 million light years from Earth, but even at that great distance it is considered a neighbour of our own galaxy, the Milky Way. The large stars in the image’s foreground are stars in the Milky Way. Because NGC 3981 is inclined towards Earth, astronomers are able to look right into the center of the galaxy. The bright center of the galaxy is dominated by a super-massive black hole (SMBH). The image shows the vast and delicate-looking spiral arms of the galaxy, which are star-forming regions full of dust. The disc itself is lit up with a host of hot young stars. Some of the spiral arm appears stretched out and misshapen, possibly due to an encounter with another galaxy at some time in the distant past. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1677683741604-L76M73WNFU0KZW8SLLPU/image-asset.jpeg Galaxies - NGC 3169 "The Scorpion Galaxy" NGC 3169 “The Scorpion Galaxy” Spiral galaxy NGC 3169 appears to be ready for the strike. Well, only with a bit of imagination. Spiral galaxy NGC 3169 appears to be unraveling in this cosmic scene, played out some 70 million light-years away just below bright star Regulus toward the faint constellation Sextans. Its beautiful spiral arms are distorted into sweeping tidal tails as NGC 3169 (left) and neighboring NGC 3166 (right) exhibits distortion in its dust lanes as they interact gravitationally, eventually probably tearing each other apart. This is often the case for proximate galaxies in the local universe. In fact, drawn out stellar arcs and plumes, indications of gravitational interactions, seem rampant in the deep and colorful galaxy group photo. Smaller, dimmer NGC 3165 at bottom right. NGC 3169 is also known to shine across the spectrum from radio to X-rays, harboring an active galactic nucleus that is likely the site of a supermassive black hole.

It’s often referred to as the hamburger galaxy. I have to say if I’m going to eat a burger from fast food place it will be Culvers! And this one looks delicious, must be a bacon butter deluxe. It’s also one of the galaxies in the Leo triplet and has a tidal tail that stretches 300,000 light years seen in a nice detail in this image. While classified as unbarred, there is some speculation that it is a barred galaxy due to the X shaped bulge in the central portion. Bar formation is often triggered by interaction with other galaxies, and 3628 is interacting with the other two galaxies in the triplet. The galaxy features numerous dust lanes and several obvious regions of active star formation. There are many distant background galaxies throughout the image. Image Processing and Calibration: Mark Hanson Data: Martin Pugh Enjoy, Mark NGC 3628, also known as the Hamburger Galaxy or Sarah's Galaxy, is an unbarred spiral galaxy about 35 million light-years away in the constellation Leo. It was discovered by William Herschel in 1784. It has an approximately 300,000 light-years long tidal tail. Along with M65 and M66, NGC 3628 forms the Leo Triplet, a small group of galaxies. Its most conspicuous feature is the broad and obscuring band of dust located along the outer edge of its spiral arms, effectively transecting the galaxy to the view from Earth. Amateur small equipment has demonstrated to be competitive tools to obtain ultra-deep imaging of the outskirts of nearby massive galaxies and to survey vast areas of the sky with unprecedented depth. Over the last decade, amateur data have revealed, in many cases for the first time, an assortment of large-scale tidal structures around nearby massive galaxies and have detected hitherto unknown low surface brightness systems in the local Universe that weren’t detected so far by means of resolved stellar populations or Hi surveys. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1711452708656-KBWFTOVUAR4VOGHSL43F/image-asset.jpeg Galaxies - Arp 271 Arp 271 The Tender Dance Located about 130 million light-years away, the Arp 271 pair is about 130,000 light-years across. It was originally discovered in 1785 by William Herschel. It is speculated that the Milky Way will undergo a similar collision in about five billion years with the neighbouring Andromeda Galaxy, which is currently located about 2.6 million light-years away in the constellation Virgo. Arp 271 comprises galaxies NGC 5426 and NGC 5427, two similar spiral galaxies that glide past each other in a cosmic dance that is choreographed by gravity. It is uncertain whether the galaxies will eventually collide. They will continue to interact for tens of millions of years, creating new stars due to the mutual gravitational attraction between the galaxies, seen here are obvious signs of interaction by the bridge of stars already connecting the two. Our own Milky Way Galaxy will undergo a similar collision in the far future with the Andromeda galaxy, which is now located about 2.6 million light years away from the Milky Way.

Barred spiral NGC 5101 (middle left) and nearly edge-on system NGC 5078 (middle right) are separated on the sky by about 0.5 degrees or about the apparent width of a full moon. Found within the boundaries of the serpentine constellation Hydra, both are estimated to be around 90 million light-years away and similar in size to our own large Milky Way galaxy. In fact, if they both lie at the same distance their projected separation would be only 800,000 light-years or so. That's easily less than half the distance between the Milky Way and the Andromeda Galaxy. NGC 5078 is interacting with a smaller companion galaxy, cataloged as IC 879, seen just right of the larger galaxy's bright core. Even more distant background galaxies are scattered around the colorful field. Some are even visible right through the face-on disk of NGC 5101. But the prominent spiky stars are in the foreground, well within our own Milky Way. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1706449243999-C1GR42UT6XX27TRP85T8/NGC+2090-Selby+HansonsThumb.jpg Galaxies - NGC 2090 in Columba NGC 2090 in Columba NGC 2090 is an infrequently imaged spiral galaxy located 40 million light years away in Columba.

NGC 2090 was one of 18 galaxies that were part of the HST Extragalactic Distance Scale Key Project to better define the value of the Hubble constant.

It was discovered by James Dunlop in 1826 and subsequently entered into the New General Catalogue as NGC 1291 by Johan Ludvig Emil Dreyer. John Herschel then observed the same object in 1836 and entered it into the catalog as NGC 1269 without realizing that it was a duplicate. This galaxy was cited as an example of a "transitional galaxy" by NASA's Galaxy Evolution Explorer team in 2007.The galaxy NGC 1291 is about 12 billion years old—and that’s old. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1702949124954-K7NKP9V93PHPMTL9XLOW/NGC259T.jpg Galaxies - NGC 289 About 70 million light-years distant, gorgeous spiral galaxy NGC 289 is larger than our own Milky Way. Seen nearly face-on, its bright core and colorful central disk give way to remarkably faint, bluish spiral arms. The extensive arms sweep well over 100 thousand light-years from the galaxy's center. At the top left in this sharp, telescopic galaxy portrait the main spiral arm seems to encounter a small, fuzzy elliptical companion galaxy interacting with enormous NGC 289.

It’s one of the largest and closest barred spirals galaxies to us. It has hosted many supernova explosions. At least six (likely 7)of these were observed supernovae and nearly 300 supernovae remnants. Its center is mysterious and unusual; the supermassive black hole at its heart is not alone. This striking galaxy displays a phenomenon known as a double nucleus. The double Nucleus does not mean it has 2 black holes but rather a single supermassive black hole with a large lopsided disk of stars orbiting which makes it look like dual nucleus. M 83 has a "bar" of stars slicing through its center, leading to its classification as a barred spiral. Our own Milky Way also belongs to this category as well. These bars are thought to act a bit like a Chanel, funneling gas inwards towards the galaxy's core. This gas is then used to form new stars that feed the galaxy's black hole.

Measured to be only 11 million light-years distant it is nearby though. Tilted nearly edge-on as seen from our perspective, it dominates this telescopic field of view toward the southern constellation Cetus.

Its size (about 100,000 light-years) makes it like our own galaxy, the Milky Way. It is called a "grand design" galaxy because of its well defined spiral arms. Two supernovae and two ultraluminous X-ray sources have been discovered in NGC 7424. On December 10, 2001, the Australian amateur astronomer Robert Evans discovered SN 2001ig, a rare Type IIb supernova on the outer edge of NGC 7424. At the time of its maximum, the supernova was only three times fainter than the whole galaxy. It must have been a splendid firework! It is now believed that indeed this supernova arose from the explosion of a very massive star, a so-called Wolf-Rayet star, which together with a massive hot companion belonged to a very close binary system in which the two stars orbited each other once every 100 days or so. The companion probably periodically stripped the outer hydrogen-rich envelope of the progenitor, accounting for the observed spectral changes, or the periodic mass loss was a result of the intense stellar wind these stars produce.

It is located at about 80 million light years from Earth, which, given its apparent dimensions, means that NGC 5084 is at least 200,000 light years across. It is one of the largest and most massive galaxies in the Virgo Supercluster. William Herschel discovered it on March 10, 1785. It is a member of the NGC 5084 Group of galaxies, which is a member of the Virgo II Groups, a series of galaxies and galaxy clusters strung out from the southern edge of the Virgo Supercluster. The galaxy is seen nearly edge-on, with inclination 86°, and features a warped disk and large quantities of HI gas extending along the disk, probably accumulated after multiple accretions of smaller galaxies.

This galaxy is rarely Photographed. The galaxy lies approximately 133 million light years away and was discovered by John Herschel. What an interesting vibrant galaxy with its many spiral arms, looks as if it’s spinning itself apart. There is very little I could find about this galaxy anywhere. This galaxy has very heavy concentrations of dust in the central portion, the heavily interwoven arms have numerous star forming regions. The arms stretch quite far from the central portion of the galaxy and seemingly fade into a blue haze. Several other galaxies can be seen scattered across the field of view, including the smaller face-on spiral NGC 6902B to the upper left. And far in the background countless distant galaxy groupings can be seen as small fuzzy dots throughout the image.

The group is often referred to as The Grus Quartet, but NGC7552 is out of this field of view. This galaxy triplet lies in the southern constellation of Grus and the three spiral galaxies (NGC 7582, 7590, 7599) exhibit telltale signs of gravitational interactions, such as the distortions of the upper two galaxies distending them toward the lower, NGC 7582 galaxy. Numerous other galaxies occur in this field-of-view. Often they are easily distinguished from the stars by their extended fuzzy halos or oblong shapes. The background galaxies lie at a much greater distance than the triad, which is about 60M light-years away. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1689624089419-5KXPFPNIZNUH06UX4JA7/image-asset.jpeg Galaxies - NGC 2935 NGC 2935 NGC 2935 is a barred spiral galaxy 125 million light years away in Hydra.

It took Bindon Stoney using Lord Rosse's 72" in 1851 to discover the smaller galaxy in the pair which became NGC 1889. Arp catalogued the pair as Arp 123 in his group of "Ellipticals close to and perturbing spirals". NGC 1888 does look as if it is being distorted by an encounter with extended spiral arms. The galaxy does have a spiral arm on the opposite side to NGC 1889 which contains lots of young blue stars. The pair are almost certainly in the early throws of a merger.

First, spiral galaxy M94 has an inner ring of newly formed stars surrounding its nucleus, giving it not only an unusual appearance but also a strong interior glow. A leading origin hypothesis holds that an elongated knot of stars known as a bar rotates in M94 and has generated a burst of star formation in this inner ring. Observations have also revealed another ring, an outer ring, one that is more faint, different in color, not closed, and relatively complex. What caused this outer ring is currently unknown. M94, pictured here, spans about 45,000 light years in total, lies about 15 million light years away, and can be seen with a small telescope toward the constellation of the Hunting Dogs (Canes Venatici). https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1687266067479-ZZV0VXEJ42C1O71ZQN48/image-asset.jpeg Galaxies - NGC 6384 NGC 6384 is a barred spiral galaxy of about 150.000 light-years across that lies some 80 million light-years away in the constellation of Ophiuchus (The Serpent Bearer). It is speeding away from us at roughly 1680 kilometers per second. The galaxy has blue spiral arms laced with dark dust lanes and a yellowish core. Star formation in the center is being fueled by the galaxy’s bar structure; astronomers think such galactic bars funnel gas inwards, where it accumulates to form new stars. Many stars have already come to the ends of their lives in NGC 6384, but in 1971, we could witness one of its stars explode as a Type Ia supernova, which stood out against the bright foreground stars. This occurs when a compact star that has ceased fusion in its core, called a white dwarf, increases its mass beyond a critical limit by gobbling up matter from a companion star. A runaway nuclear explosion then makes the star suddenly as bright as a whole galaxy. Supernova explosions are enriching the intergalactic gas with elements like oxygen, iron, and silicon that will be incorporated into new generations of stars and planets. The positioning of NGC 6384, not far from the center of the Milky Way in the sky, means that it is somewhat obscured by our galaxy’s dust and stars. Combined with the galaxy’s low surface brightness, NGC 6384 is a bit of a challenging target for astrophotographers. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1686146703841-PKTEAYEO1P5QUDOVBIWM/M74Done.jpg Galaxies - M 74 Messier 74 (also known as NGC 628) is a spiral galaxy in the constellation Pisces. It is at a distance of about 32 million light-years away from Earth. The galaxy contains two clearly defined spiral arms and is therefore used as an archetypal example of a grand design spiral galaxy. The galaxy's low surface brightness makes it the most difficult Messier object for amateur astronomers to observe. However, the relatively large angular size of the galaxy and the galaxy's face-on orientation make it an ideal object for professional astronomers who want to study spiral arm structure and spiral density waves. It is estimated that M74 is home to about 100 billion stars https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1685025597289-GXUMGW0TZ9V5OW1NRFF5/image-asset.jpeg Galaxies - NGC 2207 NGC 2207 “Things that go bump in the night” NGC 2207 and IC 2163 are shown here in a near collision. Located approximately 80 million light years away from Earth the powerful tidal forces from NGC 2207 have caused major distortions in the shape of IC 2163 the smaller galaxy on the right. The interaction has caused streams of stars and gas to extend as far as 100 thousand light years from IC 2163. The near collision is estimated to have taken place around 40 million years ago and given the gravitational influence of NGC 2207 it is very likely the IC 2163 will be pulled back for another round and in a billion or so years the galaxies will merge. The tidal streams seen in the image will over time likely become star forming regions.

Most galaxies are members of clusters of galaxies. In these, they move around among each other in a mostly slow and graceful ballet. But every now and then, two or more of the members may get too close for comfort – the movements become hectic, sometimes indeed dramatic, as when galaxies end up colliding. This image shows an example of such a cosmic tango. As dramatic and destructive as this may seem, such an interaction event is also an enrichment, a true baby-star boom. A cosmic catastrophe like this one normally results in the formation of many new stars. This is obvious from the blueish nature of the spiral arms in NGC 6769 (lower right) and NGC 6770 (lower left) and the presence of many sites of star forming regions. The two upper galaxies, NGC 6769 and NGC 6770 are of equal brightness and size, while NGC 6771 (above) is about half as bright and slightly smaller. All three galaxies possess a central bulge of similar brightness. They consist of elderly, reddish stars and that of NGC 6771 is remarkable for its “boxy” shape, a rare occurrence among galaxies. All three galaxies are barred spiral galaxies: NGC 6769 with very tightly wound spiral arms, while NGC 6770 has two major spiral arms, one of which is rather straight and points towards the outer disk of NGC 6769. NGC 6770 is also peculiar in that it presents two comparatively straight dark lanes and a fainter arc that curves towards the third galaxy, NGC 6771. Stars and gas have been stripped off NGC 6769 and NGC 6770, starting to form a common envelope around them, in the shape of a Devil’s Mask. There is also a weak hint of a tenuous bridge between NGC 6769 and NGC 6771. All of these features testify to strong gravitational interaction between the three galaxies. The warped appearance of the dust lane in NGC 6771 might also be interpreted as more evidence of interactions. Moreover, NGC 6769 and NGC 6770 are receding from us at a similar velocity of about 3800 kilometers per second while that of NGC 6771 is slightly larger, 4200 kilometers per second. NGC 6769 was home to at least two supernovae: SN 1997de and SN 2006ox. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1682865966606-RJEWS31E54XI3N7B4KBJ/CentA24-ChileT.jpg Galaxies - Centaurus A Galaxy Description by "Sakib Rasool" This dramatic galaxy portrait depicts the disturbed and peculiar galaxy NGC 5128 in the constellation of Centaurus. The result of a merger between an elliptical galaxy and a spiral galaxy, it displays a wide variety of kinematical features. It is the closest known active galaxy at 11 million light years. The remnant of the original spiral galaxy is represented by its central dust lane highlighted along its edges with the signatures of star formation such as blue star clusters and red emission nebulae. Many cosmic collisions between galaxies trigger a massive starburst of starforming activity as the neutral gas reservoir is increased and pressure and gravity compress gas clouds into active sites of starbirth. The original collision has also strewn small dust globules across the disk of the galaxy. This intergalactic encounter between two galaxies has also deformed the structure of the original elliptical galaxy and faint tidal shells envelop the galaxy. They were originally discovered by the astronomers David Malin and David Carter in the 1970's through special photographic amplification techniques. Their discovery prompted the publication of a catalogue of shell elliptical galaxies in 1983 and there are a few hundred known to belong to this category. Images with a wider field of view than this show multiple interlocking shells that extend even further. The origin of these shells are minor mergers with multiple smaller galaxies and are created by the disruption of orbits of captured stars. NGC 5128 is also known as Centaurus A and this particular naming scheme denotes the first radio source to be discovered in a particular constellation. As it has been detected by astronomers in observations made with radio telescopes, it belongs to another category of radio galaxies. Radio galaxies are so-called as they radiate more emission in radio than in optical. They are a type of active galactic nucleus (usually abbreviated to AGN). As the name suggests, galaxies that feature an AGN have an energetic nuclear region centered around a supermassive black hole. Although not immediately apparent, the AGN activity in Centaurus A is represented optically by a long filamentary jet, which can be seen north of the core. The jet arises from an outflow of gas that has built up in the accretion disk surrounding the supermassive black hole and its narrow appearance is the product of interacting magnetic fields associated with the black hole. This jet appears as an impressive bipolar outflow in x-ray and radio images. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1682558417991-ERBWIGPFRQE5ZU2QW6KY/image-asset.jpeg Galaxies - NGC 4027 NGC 4027 (also known as Arp 22) is a barred spiral galaxy approximately 83 million light-years away[2] in the constellation Corvus. It is also a peculiar galaxy because one of its spiral arms goes out more than the other. This is probably due to a galactic collision in NGC 4027's past. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1682447328017-VQ48FGG7IHH8DYAPN6IW/image-asset.jpeg Galaxies - NGC 7285 NGC 7285 and NGC 7284 (right and left respectively) are in the process of merging.

I have to say this is one of the best amateur data sets I have worked with, and the results are quite amazing. NGC 2442 is located around 50 million light-years away in the constellation of Volans. The galaxy is 75,000 light-years wide and has quite a peculiar shape featuring two dusty spiral arms extending from a central bar that gives it a hook-like appearance. Given its appearance it is often referred to as “The Meat Hook Galaxy.” The galaxy’s distorted shape is most likely the result of a close encounter with a smaller galaxy sometime in the past. A considerable amount of IFN is present in the field proximate to the galaxy and the image shows faint star streams at the ends of the arms of the galaxy.

Along with M 65 and M66 it is part of what is referred to as the Leo triplet. The galaxy features a tidal tail (part of which is shown here) that stretches 300,000 light years). While classified as unbarred, there is some speculation that it is actually a barred galaxy due to the X shaped bulge in the central portion. Bar formation is often triggered by interaction with other galaxies, and 3628 is interacting with the other two galaxies in the triplet.

These "flocculent" spiral arms indicate that the recent history of star formation of the galaxy, known as NGC 2775, has been relatively quiet. There is virtually no star formation in the central part of the galaxy, which is dominated by an unusually large and relatively empty galactic bulge, where all the gas was converted into stars long ago. NGC 2275 is classified as a flocculent spiral galaxy, located 67 million light-years away in the constellation of Cancer. Millions of bright, young, blue stars shine in the complex, feather-like spiral arms, interlaced with dark lanes of dust. Complexes of these hot, blue stars are thought to trigger star formation in nearby gas clouds. The overall feather-like spiral patterns of the arms are then formed by shearing of the gas clouds as the galaxy rotates. The spiral nature of flocculents stands in contrast to the grand design spirals, which have prominent, well defined-spiral arms.

Also known as NGC 772, the island universe is over 100 thousand light-years across and sports a single prominent outer spiral arm in this detailed cosmic portrait. Its brightest companion galaxy, compact NGC 770, is toward the upper right of the larger spiral. NGC 770's fuzzy, elliptical appearance contrasts nicely with a spiky foreground Milky Way star in matching yellowish hues. Tracking along sweeping dust lanes and lined with young blue star clusters, Arp 78's large spiral arm is likely due to gravitational tidal interactions. Faint streams of material seem to connect Arp 78 with its nearby companion galaxies. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1665070883436-72CKLMA64R9CJKZ3AS49/image-asset.jpeg Galaxies - NGC 1097-1Meter NGC 1097 is a barred spiral galaxy 50 million light years away in Fornax. There are a number of interesting features The galaxy contains a super massive black hole 140 million times greater than our sun. The black hole is surrounded by a ring replete with new star formation. The ring is lit by an influx of material moving towards the central bar of the galaxy. The galaxy contains four optical jets (one of which is extremely faint) that seem to emanate from the nucleus region. Studies have determined the jets are not emissions but are made up of stars. There are two satellite galaxies NGC 1097 A and B. A is a peculiar galaxy which is orbiting only 42000 light years from the center of NGC 1097 while B is a dwarf galaxy which was discovered by emissions and has not been well studied.

It is at a distance of 60 million light years from Earth, with an estimated size of about 75,000 light years across. It forms with three other spiral galaxies what is termed the Grus Quartet. This galaxy appears to possess a small-scale molecular bar and a large reservoir of molecular material, but there is no evidence for current activity, either starburst or Seyfert-like, at the nucleus. In the wider frame image, at the top right is PGC 100685 which NED database puts at a distance of 1.8 billion light years.

Located a mere 60 million light-years away toward the chemical constellation Fornax, NGC 1365 is a dominant member of the well-studied Fornax galaxy cluster. This impressively sharp color image shows intense star forming regions at the ends of the bar and along the spiral arms, and details of dust lanes cutting across the galaxy's bright core. At the core lies a supermassive black hole. Astronomers think NGC 1365's prominent bar plays a crucial role in the galaxy's evolution, drawing gas and dust into a star-forming maelstrom and ultimately feeding material into the central black hole. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1665068671238-LCJOJZACH7N1NQW7XZIC/image-asset.jpeg Galaxies - NGC 6907 NGC 6907 is a spiral galaxy in Capricornus around 130 million light years away. The galaxy is only 3×2’ in the field of view and we were unable to find any other clear images that have been taken. The galaxy has two prominent spiral arms and an elliptical bulge which is offset towards the base of the arms. The galaxy also has a central bar. Of interest is NGC 6908 the small bright galaxy that appears embedded in the upper right portion of the galaxy in this image. This was originally thought to be a bright spot within NGC 6907, but has since with infrared studies been properly identified as a low luminosity lenticular galaxy situated further from us than NGC 6907. It appears that NGC 6908 passed through the disk of NGC 6907 and a stellar and gas bridge was formed between the two galaxies that has been observed as high velocity gas. It is estimated that NGC 6908 passed through the disk approximately 35 million years ago. Imaged in LRGB on our PlaneWave CDK 1000 at Observatorio El Sauce, Chile.

It forms an interacting pair with NGC 470 the spiral galaxy to the right and is classified in the Peculiar Galaxy catalog as ARP 227 and peculiar it is. NGC 474 has an unusual and complex series of shell layers and tidal streams that surround the central part of the galaxy and its core. The origin of the structure has been somewhat of a mystery, however it was recently postulated that the tidal features come from the accretion of a spiral galaxy that collided around 1.3 billion years ago and merged around 900 million years ago. Volume 660, April 2022 of AANDA in the Extragalactic Astronomy section theorizes that based on the phase-space wrapping model by Quinn the formation of the shells began by a nearly radial minor or intermediate merger of the two galaxies. The large galaxy disrupted the smaller secondary galaxy by tidal forces causing the release of stars which moved out at various radial velocities. The orbital period and position was then determined by pericentric velocities. In effect then the shells are density waves made of stars near the epicenters of their orbits and expand over time.

First discovered by William Herschel in 1785, the galaxy has numerous star streams and plumes associated with it which are probably the result of a merger with another spiral galaxy about 1 billion years ago. It may take another billion years for this merger to settle down. It was this odd shape that led to its inclusion in Arp’s catalogue of peculiar galaxies. The support for the merger scenario comes from the fact that there are two star like objects near the core of NGC 7727, one of which may be the core of the merging galaxy and the other the main core of NGC 7727. NGC 7727 does not seem to have a large reservoir of hydrogen gas to form new stars so it is probably going to become an elliptical galaxy in the future. Images from GALEX, an ultraviolet satellite, show very little star formation going on at the current time in NGC 7727 compared to its neighbor NGC 7724. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1662125971720-IXG2HUY26XQ09ESVYXSQ/NGC-6822T.jpg Galaxies - NGC 6822 Barnards Galaxy NGC 6822 (also known as Barnard's Galaxy, IC 4895, or Caldwell 57) is a barred irregular galaxy approximately 1.6 million light-years away in the constellation Sagittarius. Part of the Local Group of galaxies, it was discovered by E. E. Barnard in 1884 (hence its name), with a six-inch refractor telescope. It is one of the closer galaxies to the Milky Way. It is similar in structure and composition to the Small Magellanic Cloud. It is about 7,000 light-years in diameter. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1656700066303-8YB9ODIRCIZNUKQB6KAR/NGC4725APYMarkHanson.jpg Galaxies - NGC 4725 (Stellar Winds Observatory-Rancho Hidalgo)) NGC 4725 While most spiral galaxies, including our own Milky Way, have two or more spiral arms, NGC 4725 has only one. In this sharp color composite image, the solo spira mirabilis seems to wind from a prominent ring of bluish, newborn star clusters and red tinted star forming regions. The odd galaxy also sports obscuring dust lanes a yellowish central bar structure composed of an older population of stars. NGC 4725 is over 100 thousand light-years across and lies 41 million light-years away in the well-groomed constellation Coma Berenices. Computer simulations of the formation of single spiral arms suggest that they can be either leading or trailing arms with respect to a galaxy's overall rotation. Also included in the frame, sporting a noticably more traditional spiral galaxy look, is a more distant background galaxy.

The bizarre configuration could be caused by the chance capture of material from another galaxy by a disk galaxy, with the captured debris strung out in a rotating ring. Still, observed properties of NGC 2685 suggest that the rotating ring structure is remarkably old and stable. In this sharp view of the peculiar system also known as Arp 336 or the Helix galaxy, the strange, perpendicular rings are easy to trace as they pass in front of the galactic disk, along with other disturbed outer structures. NGC 2685 is about 50,000 light-years across and 40 million light-years away in the constellation Ursa Major. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1655831123823-8AGDBATBT06PBH7T51RI/image-asset.jpeg Galaxies - NGC 5746 “The Small Sombrero” NGC 5746 “The Small Sombrero” NGC 5746 is a barred spiral galaxy seen near edge on in Virgo.

The greatest concentration of star formation is found in the starburst regions near the ends of the galaxy s galactic bar. NGC 1672 is a prototypical barred spiral galaxy and differs from normal spiral galaxies in that the spiral arms do not twist all the way into the center. Instead, they are attached to the two ends of a straight bar of stars enclosing the nucleus. Several Ionized hydrogen regions are also visible.

It is part of the NGC 2217 Group of galaxies. It is classified as a barred spiral galaxy. A notable feature is the swirling shape of this galaxy. In its very concentrated central region we can see a distinctive, very luminous bar of stars within an oval ring. Further out, a set of tightly wound spiral arms almost form a circular ring around the galaxy. Central bars play an important role in the development of a galaxy. They can, for example, funnel gas towards the center of the galaxy, helping to feed a central black hole, or to form new stars.

It is the brightest member of a group of galaxies of the same name in the Local Supercluster of galaxies along with the Local Group. NGC 2997 contains hundreds of billions of stars and is thought to have a mass of about 100 billion times that of our Sun, but is probably less massive than our own Milky Way Galaxy. The galaxy is speeding away from us at about 1085 kilometers per second. With a disk that is inclined 45 degrees to our line of sight, NGC 2997 has an oval appearance. The inner disk is covered with dust lanes, silhouetted against the central part of the galaxy, which shows a high surface brightness. Like all grand design spirals, NGC 2997 has prominent and well-defined spiral arms, which appear to originate in the yellow nucleus. These sprawling arms are peppered with bright red blobs of ionized hydrogen which are regions of star formation, where the bright blue stars are born that generate most of the light in the arms of the galaxy. Its small nucleus, that most likely hosts a supermassive black hole, also shows an interesting structure and concentrates an older population of yellowish stars. The nucleus is surrounded by a chain of hot giant clouds of ionized hydrogen. Imaged in LRGB and Ha on a PlaneWave CDK 1000 and 700 at Obstech, Chile.

Along with the smaller galaxy NGC 1531 this pair of interacting galaxies is located about 55 million light-years away from Earth in the southern constellation of Eridanus. NGC 1531 – the small galaxy with a bright core lies just above the center of its companion and is a lenticular dwarf galaxy around 20,000 light-years across. NGC 1532, the large galaxy is a nearly edge-on, deformed barred spiral galaxy about 180 thousand light-years across. While It may possess several dwarf companion galaxies, it is clearly interacting with NGC 1531. These two galaxies are gravitationally bound and very close to each other. As a result, NGC 1532 became distorted: one of its spiral arms is warped and plumes of dust and gas are visible above its disk. The interaction has also triggered bursts of star formation in both galaxies. This is obvious in NGC 1532 where a whole new generation of massive stars has been born which are visible in the spiral arms. In addition, some material may have migrated to NGC 1531, which shows an S-shaped dust lane crossing its center. Over time the gravitational interaction of the two galaxies will tear NGC 1531 apart and merge its remains with NGC 1532.

NGC 1808 is undergoing so much star formation it has been deemed a starburst galaxy. The galaxy is moving away from us at 995 kilometers per second. NGC 1808 is distinguished by a peculiar and complex nucleus, an unusually warped disk, and strange flows of hydrogen gas out from the central regions. The galaxy’s center is the hotbed of vigorous star formation. The starburst must be at least 50 million years old, and can be no older than 100 million years old. Star formation has been rapid and continuous. Without an influx of fresh molecular gas into the central region, the star forming activity can only be maintained at this rate for another 6 to 20 million years. NGC 1808 is called a barred spiral galaxy because of the straight lines of star formation on both sides of the bright nucleus. This star formation may have been triggered by the rotation of the bar, or by matter which is streaming along the bar towards the nuclear region (feeding the starburst). Filaments of dust are being ejected from the core into the galactic halo by massive stars that have exploded as supernovae in the starburst region.

NGC 1792 is in the southern constellation of Columba. It was discovered by the Scottish astronomer James Dunlop on October 4, 1826. NGC 1792’s appearance is quite energetic looking, due to the rich neutral hydrogen nature of this galaxy new stars are forming quite rapidly. It’s both a spiral galaxy, and a starburst galaxy. Stars within these starburst galaxies are forming at quite extraordinary rates. It can be more than 10 times faster in a starburst galaxy than in a galaxy like our own the Milky Way. When galaxies have a large reservoir of gas, like NGC 1792, these short-lived starburst phases can be sparked by galactic events such as mergers and tidal interactions. One might think that these starburst galaxies would easily consume all their gas in a large forming event, However, supernova explosions and intense stellar winds produced in these powerful starbursts can inject energy into the gas and disperse it, this halts the star formation before it can completely deplete the galaxy of all its fuel. www.hansonastronomy.com Taken from SWOS in El Sauce, Chile 24” PlaneWave CDK (LRGBHA) Thank you, Mark Hanson https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1636735523081-RPS88MHZBO2X40AMG704/NGC-253+100perThumb2.jpg Galaxies - NGC 253 – Sculptor or Silver Dollar Galaxy The Sculptor Galaxy (also known as the Silver Coin, Silver Dollar Galaxy, NGC 253, or Caldwell 65) is an intermediate spiral galaxy in the constellation Sculptor. The Sculptor Galaxy is a starburst galaxy, which means that it is currently undergoing a period of intense star formation. Explanation Via APOD: NGC 253 is one of the brightest spiral galaxies visible, but also one of the dustiest. Dubbed the Silver Coin for its appearance in small telescopes, it is more formally known as the Sculptor Galaxy for its location within the boundaries of the southern constellation Sculptor. Discovered in 1783 by mathematician and astronomer Caroline Herschel, the dusty island universe lies a mere 10 million light-years away. About 70 thousand light-years across, NGC 253, pictured, is the largest member of the Sculptor Group of Galaxies, the nearest to our own Local Group of galaxies. In addition to its spiral dust lanes, tendrils of dust seem to be rising from a galactic disk laced with young star clusters and star forming regions in this sharp color image. The high dust content accompanies frantic star formation, earning NGC 253 the designation of a starburst galaxy. NGC 253 is also known to be a strong source of high-energy x-rays and gamma rays, likely due to massive black holes near the galaxy's center.

Looks like a swarm of flying insects. NGC 4753 is a lenticular galaxy located about 60 million light-years away in the constellation of Virgo. NGC 4753 was discovered by astronomer William Herschel on February 22, 1784. It is notable for having distinct dust lanes that surround its nucleus. The galaxy is a member of the Virgo II Groups, an extension of the Virgo Cluster. The distribution of dust in NGC 4753 lies in an inclined disk wrapped several times around the nucleus. The material in the disk may have been accreted from the merger of gas rich dwarf galaxy. Over several orbital periods, the accreted material eventually smeared out into a disk. Differential precession that occurred after the accretion event caused the disk to twist. Eventually, the disk settled into a fixed orientation with respect to the galaxy. The age of the disk is estimated to be around half a billion to a billion years.

It is located at a distance of circa 35 million light years from Earth, which, given its apparent dimensions, means that NGC 2835 is about 65,000 light years across. It was discovered by Wilhelm Tempel on April 13, 1884.[3] NGC 2835 is located only 18.5 degrees from the galactic plane.[4] NGC 2835 is seen nearly face-on. The galaxy features four or five spiral arms, visible in near infrared due to their population II stars.[5] The spiral arms have also numerous HII regions and stellar associations, the larger of which are 5 arcseconds across.[4] Although the galaxy is quite symmetric, the northern arms have HII regions that appear brighter than the southern ones. Also the southern arms appear less developed in their outer parts than the north ones.[6] The star formation rate in NGC 2835 is 0.4 M☉ per year and the total stellar mass of the galaxy is low, at 7.9x109 M☉.[7] In the centre of NGC 2835 lies a supermassive black hole whose mass is estimated to be 3-10 million (106.72±0.3) M☉, based on the spiral arm pitch angle.[8] https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1618242608907-CER9FCQTPBEM9DWGSHXY/NGC1055T.jpg Galaxies - NGC 1055 From Chile NGC 1055 From Chile Explanation via APOD: Big, beautiful spiral galaxy NGC 1055 is a dominant member of a small galaxy group a mere 60 million light-years away toward the aquatically intimidating constellation Cetus. Seen edge-on, the island universe spans over 100,000 light-years, a little larger than our own Milky Way galaxy. The colorful, spiky stars decorating this cosmic portrait of NGC 1055 are in the foreground, well within the Milky Way. But the telltale pinkish star forming regions are scattered through winding dust lanes along the distant galaxy's thin disk. With a smattering of even more distant background galaxies, the deep image also reveals a boxy halo that extends far above and below the central bluge and disk of NGC 1055. The halo itself is laced with faint, narrow structures, and could represent the mixed and spread out debris from a satellite galaxy disrupted by the larger spiral some 10 billion years ago.

First discovered by William Herschel in 1785, the galaxy has numerous star streams and plumes associated with it which are probably the result of a merger with another spiral galaxy about 1 billion years ago. It may take another billion years for this merger to settle down. It was this odd shape that led to its inclusion in Arp’s catalogue of peculiar galaxies. The support for the merger scenario comes from the fact that there are two star like objects near the core of NGC 7727, one of which may be the core of the merging galaxy and the other the main core of NGC 7727. NGC 7727 does not seem to have a large reservoir of hydrogen gas to form new stars so it is probably going to become an elliptical galaxy in the future. Images from GALEX, an ultraviolet satellite, show very little star formation going on at the current time in NGC 7727 compared to its neighbor NGC 7724.

Even our own galaxy practices galactic cannibalism, absorbing small galaxies that get too close and are captured by the Milky Way's gravity. In fact, the practice is common in the universe and illustrated by this striking pair of interacting galaxies from the banks of the southern constellation Eridanus (The River). Located over 50 million light years away, the large, distorted spiral NGC 1532 is seen locked in a gravitational struggle with dwarf galaxy NGC 1531, a struggle the smaller galaxy will eventually lose. Seen edge-on, spiral NGC 1532 spans about 100,000 light-years. Nicely detailed in this sharp image, the NGC 1532/1531 pair is thought to be similar to the well-studied system of face-on spiral and small companion known as M51. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1600828816317-SBR223L2F0QW3IQ3MQ45/NGC1512Thumb.jpg Galaxies - NGC 1512-New NGC 1512 NGC 1512 is a barred spiral galaxy approximately 38 million light-years away from Earth in the constellation Horologium.

It lies some 30 million light-years distant in the southern constellation Pavo and appears as only a faint, extended object in small telescopes. We see the disk of the nearby island universe tilted towards our line of sight. This remarkably detailed galaxy portrait covers an area about the angular size of the full moon. In it, the giant galaxy's elongated yellowish core is dominated by the light from old, cool stars. Beyond the core, grand spiral arms are filled with young blue star clusters and speckled with pinkish star forming regions. An extended arm sweeps past a smaller satellite galaxy at the upper left. NGC 6744's galactic companion is reminiscent of the Milky Way's satellite galaxy the Large Magellanic Cloud.

It is the brightest member of a group of galaxies of the same name in the Local Supercluster of galaxies along with the Local Group. NGC 2997 contains hundreds of billions of stars and is thought to have a mass of about 100 billion times that of our Sun, but is probably less massive than our own Milky Way Galaxy. The galaxy is speeding away from us at about 1085 kilometers per second. With a disk that is inclined 45 degrees to our line of sight, NGC 2997 has an oval appearance. The inner disk is covered with dust lanes, silhouetted against the central part of the galaxy, which shows a high surface brightness. Like all grand design spirals, NGC 2997 has prominent and well-defined spiral arms, which appear to originate in the yellow nucleus. These sprawling arms are peppered with bright red blobs of ionized hydrogen which are regions of star formation, where the bright blue stars are born that generate most of the light in the arms of the galaxy. Its small nucleus, that most likely hosts a supermassive black hole, also shows an interesting structure and concentrates an older population of yellowish stars. The nucleus is surrounded by a chain of hot giant clouds of ionized hydrogen. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1589754572966-V6OWGISUEBLL6Y28YNQF/NGC5068-WebThumb.jpg Galaxies - NGC 5068 NGC 5068 Rarely Imaged NGC 5068 is a field barred spiral galaxy in the Virgo constellation. At the center of NGC 5068 is a supermassive black hole whose mass controls the velocity dispersion of the inner stars. The bar (or bar structure) in the bulge (or center) of the galaxy is a sign that it is reaching its full maturity as a galaxy. On average, these barred spiral galaxies are supposed to be two billion years old, the bulge being the oldest and the youngest part being the arms of the galaxy and the outer ridge of the galaxy. One of the leading hypothesis of the arm formation supposes that the presence of density waves from the bulge caused the star formation to occur in a sort of spiral shape in the galaxy. NGC 5068 is about 6.8 million pc away from Earth and about 45,000 light years in diameter. In the spiral galaxy photo, we can see the bar in the center where a black hole resides. This bar is evidence that the galaxy has finished its formative years, and is starting to become fully mature. You can also see the spiral arms surrounding the center bar, representing the younger stars in the galaxy. There is a high rate of star formation in this arms, making the arms clear and bright. This spiral galaxy can be compared to the Milky Way (the galaxy in which our solar system resides), which also has a barred spiral structure, with a supermassive black hole in the bulge.

That huge swarm of over 1000 galaxies that straddles the Coma Berenices-Virgo region. However not so well known is that there is another equally large cluster in Coma Berenices known as The Coma Cluster or Abell Galaxy Cluster 1656. The main reason that this galaxy cluster is not so well known is that the cluster is nearly 10 times further away than the Virgo cluster, at a distance of over 400 million light years. This means that most of the members of the cluster are small and faint. The brightest members are the giant elliptical galaxy NGC 4889 and 4874.

Found about 40 million light-years from Earth toward the constellation of Leo, NGC 3521 has a somewhat obvious nickname: the Bubble Galaxy. When viewed from afar, it appears to be completely encased in a large, but faint, bubble. What looks like a second bubble also surrounds its nucleus. Astronomers believe the shell is an artifact of galaxy mergers.. namely when NGC 3521 and several smaller galaxies collided. In the immediate aftermath, a bunch of gas, dust and rogue stars were strewn all throughout space—eventually coalescing back into a familiar form (features such as halos, stellar streams and tidal tails are common in events like this). The merger also led to the formation of many star clusters, which are pink-tinged. Those with a blue-white hue are high-mass, bright and incredibly hot. They will only live for a few hundred million years before they explode as supernovae—reseeding space with raw materials. The first image is with No Ha and the image below that has some HA added.

Located about 50 million light-years away, the galaxy's two spiral arms extending from a pronounced central bar give it a hook-shaped appearance. This deep color image also shows the arms' obscuring dust lanes, young blue star clusters and reddish star forming regions surrounding a core of yellowish light from an older population of stars. But the star forming regions seem more concentrated along the drawn-out (right side) spiral arm. The distorted structure is likely the result of an ancient close encounter with the smaller galaxy seen near the top left of this field of view. The two interacting galaxies are separated by about 150,000 light-years at the estimated distance of NGC 2442. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1583505261168-KVKUN2OYQHX1ZSOI1EWB/NGC-4038-4039Thumb.jpg Galaxies - The Antennae Galaxy Explanation: Some 60 million light-years away in the southerly constellation Corvus, two large galaxies are colliding. Stars in the two galaxies, cataloged as NGC 4038 and NGC 4039, very rarely collide in the course of the ponderous cataclysm that lasts for hundreds of millions of years. But the galaxies' large clouds of molecular gas and dust often do, triggering furious episodes of star formation near the center of the cosmic wreckage. Spanning over 500 thousand light-years, this stunning view also reveals new star clusters and matter flung far from the scene of the accident by gravitational tidal forces. The remarkable mosaicked image was constructed using data from the ground-based Subaru telescope to bring out large-scale and faint tidal streams, and Hubble Space Telescope data of extreme detail in the bright cores. The suggestive visual appearance of the extended arcing structures gives the galaxy pair its popular name - The Antennae. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1577975293531-QNXU7C5P9QL1UY6ALW3A/CropNGC908.jpg Galaxies - NGC 908 NGC 908 is an unbarred spiral galaxy in the constellation Cetus.

Stretched along the 100,000 light-year long tidal tails, are clumps resembling dwarf galaxies, but lacking old stars, apparently dominated by young stars and active star forming regions. Found to be unusually rich in elements heavier than hydrogen and helium, the dwarf galaxies were likely born in intergalactic space, recycling the enriched debris from NGC 5291 itself.

It was discovered by German-British astronomer William Herschel on 20 October 1784. It is dominated by millions of bright stars and dark dust, in spiral arms rotating about the center. Open clusters containing bright blue stars are sprinkled along these spiral arms, with dark lanes of dense interstellar dust between. Less visible are dim normal stars and interstellar gas, producing such high mass that they dominate the dynamics of the inner galaxy. Not visible is matter of unknown form called dark matter, needed to explain the motions of the visible material in the outer galaxy. The galaxy is approximately 200,000 light-years across, in between the sizes of the Andromeda Galaxy and our home galaxy, the Milky Way. NGC 1232 and its satellite are part of the Eridanus cluster of galaxies, along with NGC 1300. NGC 1232A is a satellite galaxy of NGC 1232. It is thought to be the cause of unusual bending in the spiral arms. In 1988, NGC 1232A was estimated to be 68 million light-years away while NGC 1232 was estimated to be 65 million light-years away.

Still, the tantalizing island universe is a clearly a telescopic treasure in southern skies. It shares a bright core, clumpy dust lanes, and loosely wrapped spiral arms with spiky foreground stars of the Milky Way and the more diminutive galaxy NGC 131 in this sharp cosmic vista. From a distance of about 60 million light-years, NGC 134 is seen tilted nearly edge-on. It spans some 150,000 light-years, making it even larger than our own Milky Way galaxy. NGC 134's warped disk and faint extensions give the appearance of past gravitational interactions with neighboring galaxies. Like the much closer and brighter Sculptor galaxy NGC 253, tendrils of dust appear to rise from a galactic disk sprinkled with blue star clusters and pinkish star forming regions. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1564407389818-2TW5FVGCXVPCIRW4GXRK/Thumb.jpg Galaxies - NGC 4273 NGC 4273 and NGC 4281 are members of a small sub-group of the Virgo Cluster. In the image below, NGC 4273 is the face-on spiral near the centre, while NGC 4281 is the larger elliptical galaxy to the upper left. The eastern spiral arm of NGC appears to be distorted a little, probably by the gravitational pull of NGC 4277 just to its left. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1564238443133-16VSIIQ53B6TELB4QGW0/Abell2151Thumb.jpg Galaxies - Abell 2151 Abell 2151 Galaxy Cluster Copyright Mark Hanson Description by Sakib Rasool Abell 2151 is a mighty cluster of galaxies with a surplus of beautiful interacting galaxies. Interestingly its distribution is quite chaotic and lacks the typical central elliptical galaxy that is a common feature of most galaxy clusters. However the brightest galaxy is the elliptical NGC 6041. In the grand scheme of the universe, Abell 2151 (also known as the Hercules Galaxy Cluster) is located 500 million light years away and covers an area of 6 million light years with about 200 galaxies. It is part of the Hercules Supercluster, which is part of an even larger extragalactic structure simply known as the Great Wall. This has a huge span of 500 million light years and was discovered in the 1980's by Margaret Geller and John Huchra. One aspect of Abell 2151 that is immediately apparent is the abundance of peculiar and interacting galaxies. In fact, there are so many that a record number of four were included in the Arp Atlas, the most for any galaxy cluster. These include Arp 71 (NGC 6045), Arp 122 (NGC 6040), Arp 172 (IC 1178/81) and Arp 272 (NGC 6050/IC 1179). NGC 6040 is an interesting pair of galaxies interacting with each other and in the process of being absorbed into the galaxy cluster, its neutral hydrogen gas has been removed through ram pressure stripping, a phenomenon that has been observed in other galaxy clusters. NGC 6050 and IC 1179 represent a titanic collision between two behemoths that have been observed with the Hubble Space Telescope, which appears to show a third member in this system. Arguably the most distinguished member of Abell 2151 is IC 1182, a strange chaotic wreck of a galaxy that was somehow overlooked by Halton Arp. Although it is tempting to perceive the elongated blue structure as a jet launched from its core, it is in fact a tidal tail with a weaker second one near the opposing side. Another famous example of tidal tails being misconstrued as jets are the ones associated with the southern galaxy NGC 1097. In IC 1182, the longer tidal tail has a length of 205,000 light years while the smaller one is 88,000 light years long. It is very llkely its unique morphology is the result of an ongoing merger between two galaxies. Another interesting conclusion drawn from professional studies is that some of the blue knots in the large tidal tail might be in the process of forming tidal dwarf galaxies!

Consisting of chaotic and disordered structure, its appearance immediately hints at its turbulent history. A characteristic it has in common with M82 are multiple spidery tendrils of ionized hydrogen gas emanating outwards from its core. These were first discovered in 1974. Classed as a starburst dwarf galaxy, NGC 3077 is relatively nearby at 12 million light years. A series of tidally disrupted structures with striking blue stars is debris scattered from previous gravitational encounters with the other trio members, most notably M81. This structure has been nicknamed the "Garland" by professional astronomers and was first detected in photographic plates in the 1980's. Signatures of star formation triggered by tidal interactions are present as the many HII regions interspersed within its structure and at least 36 separate HII regions have been catalogued. Another unusual aspect of this perturbed galaxy is the subtle blue core, which is surrounded by a disk consisting of an older stellar population. Normally it is the other way round, spiral galaxies consist of a golden core with blue spiral arms. The strange distribution of stellar matter is an indicator of a massive starburst of new stars being formed near the core due to the raw material of star formation being centrally concentrated at the nucleus. Optical images such as this one don't always show the full picture of the morphology and kinematics of galaxies and other instruments are utilised to detect different parts that belong to other areas of the electromagnetic spectrum. Observations with radio telescopes are able to map the distribution of neutral hydrogen gas (HI), which is invisible optically. Witin the past few decades, the HI gas content of the M81 trio has been studied in superb detail and consists of many streamers and bridges connecting M81 and NGC 3077 together. A huge HI tail is also associated with NGC 3077 and contains more neutral gas than the core.

It is receding from us at approximately 1,362 kilometers per second. The name “Arp 185” derives from being included in Arp’s Atlas of Peculiar Galaxies, a catalog of 338 peculiar galaxies, drawn up by Halton Arp in the years from 1962 through 1967 and published by the California Institute of Technology. Arp 185 is on the list of the “100 Brightest Arps”, which was sorted and created by Jim Shields. NGC 6217 has moderately-wound spiral arms, and a prominent, long and well-defined bar running across a spherical, very bright active nucleus where probably a supermassive black hole resides. Throughout the galaxy we can see narrow, filamentary dark dust lanes, blue clusters full of hot, young stars, and dozens of pink star-forming emission nebulae. It has been characterized as a starburst galaxy, which means it is undergoing a high rate of star formation compared to a typical galaxy. It is dominated by stars less than 10 million years old, giving the galaxy a blue hue. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1557335021550-S050LWBUTV627AZ0THJM/5557Thumb.jpg Galaxies - NGC 5557 The cosmic scene depicted in this deep astrophoto is the region towards the elliptical galaxy NGC 5557 in the constellation of Bootes. For a long time, ellipticals were regarded as the placid endpoint of galactic evolution. However this view has been challenged by the discovery of tidal shells and plumes around a large number of elliptical galaxies in the past few decades. These extended structures convey a rich kinematical history involving mergers with other galaxies, a process commonly associated with interacting spiral galaxies. Located at a distance of 126 million light years, NGC 5557 is enveloped by multiple shells and extremely faint tidal plumes that extend for 1.2 million light years with less than the full extent included in the field of view of this image. Professional studies have surmised the material constituting the tidal structures likely originates in a major merger with a large galaxy whose original structure has been disrupted beyond recognition. In the chaos of all this tidal disruption, the formation of so-called tidal dwarf galaxies can be triggered. At least three tidal dwarf galaxies have been discovered associated with NGC 5557 but only one is included in the field of view of this image, it is the fuzzy detached object located at the northern tip of the curved tidal stream to the south. Their discovery represent the oldest examples of their kind in the nearby universe and have an estimated age of 2-4 billion years. Complementing this hive of activity is the interacting galaxy pair NGC 5544-5, which are also collectively known as Arp 199. NGC 5544 is the face on galaxy while NGC 5545 is the blue spiral that overlaps it. They also have a similar distance of 140 million light years. Interestingly, all three galaxies were discovered on the same night in 1785 by William Herschel. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1556660265533-R322BBJTGEDAHQTNSFXN/M95Thumb.jpg Galaxies - Messier 95 Messier 95, also known as M95 or NGC 3351, is a barred spiral galaxy located about 33 million light-years away in the zodiac constellation Leo.

On 16 March 2012, a supernova was discovered in M95. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1556650561392-X6O42QV60Y614DLLZWRR/M87Thumb.jpg Galaxies - M87- Elliptical Galaxy with Jet M87- Elliptical Galaxy with Jet Explanation Via AOPD: In spiral galaxies, majestic winding arms of young stars, gas, and dust rotate in a flat disk around a bulging galactic nucleus. But elliptical galaxies seem to be simpler. Lacking gas and dust to form new stars, their randomly swarming older stars, give them an ellipsoidal (egg-like) shape. Still, elliptical galaxies can be very large. Centered in this telescopic view and over 120,000 light-years in diameter, larger than our own Milky Way, elliptical galaxy M87 (NGC 4486) is the dominant galaxy of the Virgo Galaxy Cluster.

The result of a merger between an elliptical galaxy and a spiral galaxy, it displays a wide variety of kinematical features. It is the closest known active galaxy at 11 million light years. The remnant of the original spiral galaxy is represented by its central dust lane highlighted along its edges with the signatures of star formation such as blue star clusters and red emission nebulae. Many cosmic collisions between galaxies trigger a massive starburst of starforming activity as the neutral gas reservoir is increased and pressure and gravity compress gas clouds into active sites of starbirth. The original collision has also strewn small dust globules across the disk of the galaxy. This intergalactic encounter between two galaxies has also deformed the structure of the original elliptical galaxy and faint tidal shells envelop the galaxy. They were originally discovered by the astronomers David Malin and David Carter in the 1970's through special photographic amplification techniques. Their discovery prompted the publication of a catalogue of shell elliptical galaxies in 1983 and there are a few hundred known to belong to this category. Images with a wider field of view than this show multiple interlocking shells that extend even further. The origin of these shells are minor mergers with multiple smaller galaxies and are created by the disruption of orbits of captured stars. NGC 5128 is also known as Centaurus A and this particular naming scheme denotes the first radio source to be discovered in a particular constellation. As it has been detected by astronomers in observations made with radio telescopes, it belongs to another category of radio galaxies. Radio galaxies are so-called as they radiate more emission in radio than in optical. They are a type of active galactic nucleus (usually abbreviated to AGN). As the name suggests, galaxies that feature an AGN have an energetic nuclear region centered around a supermassive black hole. Although not immediately apparent, the AGN activity in Centaurus A is represented optically by a long filamentary jet, which can be seen north of the core. The jet arises from an outflow of gas that has built up in the accretion disk surrounding the supermassive black hole and its narrow appearance is the product of interacting magnetic fields associated with the black hole. This jet appears as an impressive bipolar outflow in x-ray and radio images.

Its spiral arms are punctuated with the red glow of hydrogen gas concentated in emission nebulae and HII regions, the birthplaces of new stars. Many dust lanes swirl around its core with the distribution of its gas and dust being asymmetrical as well as the core region being placed off-centre. The entire galaxy spans 100,000 light years making it about the same size as the Milky Way at a close distance of 35 million light years. The surrounding region is filled with a wide variety of background galaxies much further away.

M91 is about 63 million light-years away from the earth. It was the last of a group of eight nebulae discovered by Charles Messier in 1781. Originally M91 was a missing Messier object in the catalogue as the result of a bookkeeping mistake by Messier. It was not until 1969 that amateur astronomer William C. Williams[3] https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1551406244007-ZGX8O05VIX24IBM0PVEO/NGC+3642APODCrop.jpg Galaxies - NGC 3642 NGC 3642 is a spiral galaxy in constellation Ursa Major. The galaxy has a low-ionization nuclear emission-line region. It is located at a distance of circa 30 million light years from Earth, which, given its apparent dimensions, means that NGC 3642 is about 50,000 light years across. The galaxy is characterised by an outer pseudoring, which was probably formed after the accretion of gas rich dwarf galaxy.[2] Contents 1 Structure 2 Nearby galaxies 3 References 4 External links Structure NGC 3642 is a spiral galaxy without bar.[2] In the nucleus there is a supermassive black hole with estimated mass 26-31 millions M⊙, based on the intrinsic velocity dispersion as measured by the Hubble Space Telescope,[3] or 15 millions M⊙, based on the bulge luminosities in near-infrared Ks-band.[4] Around the nucleus, an one-armed spiral forms a ring, and it is possible that it leads material towards the nucleus. The nucleus surrounded by an inner flocculent spiral. The outer part of the spiral forms a pseudoring that extents for about half a circle. The outer part of the spiral is warped, while its main part features an ordinary differentially rotating disk. The HI gas is also warped and extents more in the western side.[2] https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1547502847651-62ZWZJT0YT2M8S24G51G/NGC2655WebThumb.jpg Galaxies - NGC 2655 - Arp 225 "Floating in the serenity of the universe like a cosmic ammonite shell, NGC 2655 is an impressive example of a lenticular galaxy. Located 60 million light years away towards the constellation of Camelopardalis, its series of outer shell structures and faint tidal loops are nicely complemented by internal dust lanes near its core. Its panoply of morphological kinematics are indicative of a merger between two galaxies in the past, an intergalactic event that is now known to be a common feature of the evolution of galaxies. Other signatures of a past merger that aren't apparent to the eye are vast clouds of neutral hydrogen surrounding the galaxy that were uncovered in observations made using radio telescopes by professional astronomers. The unusual appearance of NGC 2655 brought it to the attention of the famous astronomer Halton Arp who added it to his atlas of peculiar galaxies under Arp 225. Another distinction is that the core is very luminous, which means that NGC 2655 belongs to the category of active galaxies known as Seyfert galaxies, which were named after the astronomer Karl Seyfert. The luminosity of Seyfert galaxies is thought to derive from a transfer of matter onto an accretion disk around a supermassive black hole. NGC 2655 is the brightest member of a small group of galaxies that also includes NGC 2715 (not visible in image). The diameter of NGC 2655 is approximately 200,000 light years but the envelope of neutral hydrogen gas discovered in the 1980's is about 500,000 light years." https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1547143580895-1U4P0SL99O1W2MA17FQI/NGC2782NewWebT.jpg Galaxies - NGC 2782 aken from DGRO Rancho Hidalgo Animas, New Mexico 14.5" RCOS F8, Apogee U16M High Cooling Luminance 360, Red 180, Green 140, Blue 180 Calibrated,combined in CCD Stack all other processing done using PS5. The starburst galaxy NGC 2782 lies about 110 million light years away toward the Lynx constellation. This shows the result when two galaxies of unequal mass collided about 200 million years ago. Their gravitational pull ripped out two tails of debris with very different properties. The optically bright eastern tail has some neutral hydrogen gas and molecular gas at the base of the tail, and an optically bright, but gas-poor concentration at the end of the tail. The optically faint western tail is rich in neutral hydrogen gas, but has no molecular gas, yet astronomers have recently found blue star clusters younger than 100 million years along both tails, indicating that those stars formed within both tails after the galaxy collision occurred. Current star-formation theory suggests that star clusters are formed from the collapse of giant molecular gas clouds, but if this were the case, astronomers would expect to see remnants of the molecular gas which helped give birth to the stars in both of the tails of NGC 2782. Finding unexpected young star clusters in the western tail could help explain why stars form in other places where there is little molecular gas, like the outer edges of the Milky Way galaxy or in the debris of other galaxy collisions. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1546869623065-OHX8YAIZ66U0ASUQ2U31/NGC4214New+WebThumb.jpg Galaxies - NGC 4214 Dwarf Galaxy Taken from DGRO Rancho Hidalgo Animas, New Mexico 14.5" RCOS F8, Apogee U16M High Cooling Luminance 390, Red 140, Green 140, Blue 140, Calibrated,combined in CCD Stack all other processing done using PS5. The dwarf galaxy NGC 4214 is ablaze with young stars and gas clouds. Located around 10 million light-years away in the constellation of Canes Venatici (The Hunting Dogs), the galaxy's close proximity, combined with the wide variety of evolutionary stages among the stars, make it an ideal laboratory to research the triggers of star formation and evolution. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1545961031226-HC92C2EHIA0SOTHZ4VLJ/NGC918-WebSmall.jpg Galaxies - NGC 918 https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1542672917276-9X2WMQSNKCFH21EEKLSU/NGC2146Apod-2Crop.jpg Galaxies - NGC 2146 NGC 2146 is a barred spiral galaxy in the constellation Camelopardalis. The most distinctive feature is the dusty spiral arm that has looped in front of the galaxy's core as seen from our perspective. The forces required to pull this structure out of its natural shape and twist it up to 45 degrees are colossal. The most likely explanation is that a neighboring galaxy is gravitationally distorting the orbits of many of NGC 2146's stars. It is probable that we are currently witnessing the end stages of a process that has been occurring for tens of millions of years. NCG 2146 is undergoing intense bouts of star formation, to such an extent that it is referred to as a starburst galaxy. This is a common state for barred spirals, but the extra gravitational disruption that NGC 2146 is enduring no doubt exacerbates the situation, compressing hydrogen-rich nebulas and triggering stellar birth. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1542217569383-B5MVKC15PJHMXQBCIM4N/Arp284FinalApodsmall.jpg Galaxies - Arp 284 Three Giant Leaps Image Credit & Copyright: Mark Hanson Description by Brian Ottum Three different objects in this image demonstrate the immensity of the known universe. The bright star is 16 Piscium, located just 100 light-years from Earth, within our home Milky Way galaxy. The pair of interacting galaxies (Arp 284) are a thousand times further away than the bright star, 100 million light-years from Earth. Finally, the tiny blue quasar's (B2333+019A) & (B2334+019A) are a hundred times further away than the pair of galaxies at 10 and 11 billion light-years from Earth. The 3 different objects demonstrate the immense power of gravity. 1. The bright star creates light through gravity-generated fusion. 2. Gravity is pulling the pair of galaxies Arp 284 also known as (NGC 7714 and NGC 7715) toward each other, gradually tearing them apart in the process. 3. Finally, 2 separate super massive black holes have so much gravitational pull that it is vacuuming up its host galaxy, allowing only an extremely bright jet of light (the 2 quasars) to escape and be blasted towards Earth. We are seeing light that started its journey when the universe was relatively young at just 3 billion years old. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1540215046137-KCCLUV0MS74GBHEETB4J/NGC6140Thumb.jpg Galaxies - NGC 6140 https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1530231184218-9FUN8VMV9SVRFS2HQE9A/NGC5907+APOD-2Thumb.jpg Galaxies - NGC 5907 "Slicing through the dark cold depths of space towards the constellation of Draco, the knife edge disk of the Splinter Galaxy is depicted in this impressively deep image. Otherwise catalogued as NGC 5907, rusty coloured dust lanes near the centre compete with a stainless steel blue outer edge composed of younger stars. This part also features a lower amount of dust obscuration. The beauty of long exposure images taken with remote observatories under dark skies elucidate incredibly low surface brightness tidal streams. Originally discovered by a team of professional astronomers in 1998, it wasn't until the pioneering work of David Martinez-Delgado and his crack squad of amateur astro-detectives (of which a certain Mark Hanson is a member) that it was conclusively confirmed as a true definite structure around the galaxy. Like the myriad of clues left behind at a crime scene, professional astronomers can reconstruct the history of an intergalactic murder mystery but this time involving a huge galaxy like NGC 5907 and a smaller companion galaxy that is disrupted and ultimately destroyed. The tidal stream that is recovered in deep optical images could be thought of as the ghost of the previous satellite galaxy. This structure is the product of the effect of the gravity of the larger galaxy and the decay of the orbit of the smaller galaxy and it leaves behind a trail of stars ripped from it that trace its disrupted orbit around the larger galaxy. This tidal stream has an estimated size of 150,000 light years." https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1527720376046-EOTTZLPLIZA6O0Z4NQ8U/M86LRGBHA.jpg Galaxies - M 86 Taken from SWO "This stunning image depicts the dynamic and dramatic centre of the Virgo Cluster. At a distance of approximately 50 million light years, it is the closest galaxy cluster to Earth and is dominated by the large elliptical galaxies M86 and M84. However what makes this image special is the addition of 30 hours of narrowband Ha exposures that illuminate blazing filaments of gas that emit in the hydrogen alpha line! These are the product of a collision between M86 and the blue peculiar deformed spiral galaxy NGC 4438. With a staggering length of 400,000 light years, they signify the tempestuous relationship between interacting galaxies at the heart of galaxy clusters. NGC 4438 is also interacting with its elliptical companion NGC 4435 and both are collectively catalogued as Arp 120 in the Arp Atlas of peculiar galaxies. Another sign of peculiarity is a rarely seen tidal tail extending from NGC 4435. Another point of interest is a swarm of low surface brightness dwarf galaxies enveloping M86. These are currently being analysed by professional astronomers to help gain insight into the nature of the elusive dark matter purported to exist within the framework of cosmological models." https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1527717682505-TJ3VK4O3JGR7BD1JS6HR/NGC+5566Apod-2FullCrop.jpg Galaxies - NGC 5566- Arp 286 From SWO Explanation Via APOD: A remarkable telescopic composition in yellow and blue, this scene features a trio of interacting galaxies almost 90 million light-years away, toward the constellation Virgo. On the left, two, spiky, foreground Milky Way stars echo the trio galaxy hues, a reminder that stars in our own galaxy are like those in the distant island universes. Predominately yellow, with sweeping spiral arms and dust lanes, NGC 5566 is enormous, about 150,000 light-years across. Just below it lies small, blue NGC 5569. Near center, the third galaxy, NGC 5560, is multicolored and apparently stretched and distorted by its interaction with NGC 5566. The galaxy trio is also included in Halton Arp's 1966 Atlas of Peculiar Galaxies as Arp 286. Of course, such cosmic interactions are now appreciated as a common part of the evolution of galaxies. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1525988819422-4AD6XRTHAVVIJNYLQ5T3/NGC+4449Apodsmall.jpg Galaxies - NGC 4449 in Canes Venatici "Belonging to the class of Magellanic type irregular galaxy, NGC 4449 is a small but lovely cosmic denizen of the constellation Canes Venatici. It is very close (in astronomical terms) at 12.5 million light years. Blazing across its structure is a starburst of young blue stars and active red nebulae forming new stars at a (fast) and furious pace! Detailed analysis of the starburst has determined that it started 500 million years ago. For many years, it was hypothesized that the starburst observed in NGC 4449 was triggered by an interaction with another galaxy. Enter astronomer extraordinaire David Martinez-Delgado and his pro-am collaboration project to document tidal streams in nearby galaxies. His tidal stream survey has uncovered previously unknown tidal streams in many galaxies. Utilizing a group of amateur astrophotographers led by Jay GaBany with a worldwide network of telescopes and remote observatories, it has been possible to obtain very long exposures that would not normally be possible with professional observatories due to limitations imposed by time allocation constraints. The group of amateur astrophotographers includes many famous people such as Ken Crawford, Adam Block, Fabian Neyer, a certain Mark Hanson and many others. Deep images taken by the tidal stream survey group uncovered an extremely faint tidal stream, which is the remnant of a former dwarf companion. Special image processing techniques combined with very long exposures are able to reveal very faint features that would not normally be visible. This stream can be seen as the ghostly elongated tidal feature to the south of NGC 4449. It was first discovered in 2007 by Igor Karachentsev and followed up for a definitive detection by the tidal stream survey team. The stream has a size of approximately 23,000 x 5000 light years. The accretion of smaller galaxies is a major contributing factor to galaxy assembly and is a major topic of research in astrophysics. Revealing the dim past of galaxies can help gain insight to their future and address related topics such as dark matter distribution." https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1525970482463-8GRQBU2GGMT6IJFNNRJD/M49Aopdsmall.jpg Galaxies - Messier 49 in Virgo Messier 49 in Virgo "M49 is a large elliptical galaxy with a tenuous diffuse tidal shell structure.

One of the many members of the Virgo Cluster, M49 is a giant elliptical galaxy with a size of 157,000 light years. It is home to an estimated 6000 globular clusters, which seem to be found in greater abundance in elliptical galaxies. M49 is interacting with the blue dwarf galaxy UGC 7636 below and to the left of it. This is visually illustrated by a diffuse tidal plume to the north of it stretching towards the direction of M49.

It is 60 million light-years away, and it is estimated to be 125,000 light-years across.

Both galaxies were included by Charles Messier in his 18th century collection of objects that are not comets. The one on the right is M89 and the one on the left is M90, both are between 50 and 60 million light years away along with the small companion of M90, IC 3583. This image perfectly illustrates the influence of environment on galaxy evolution. M90 was considered a placid serene galaxy with very little activity and a low star formation rate. Recent studies by professional astronomers show it to be experiencing ram pressure stripping, a phenomenon that is known to affect many galaxies in the Virgo Cluster and other galaxy clusters. Galaxy cluster environments contain lots of hot gas visible in x-rays known as the intracluster medium (ICM). The movement of a galaxy through the ICM creates a "wind" that exerts pressure that strips gas away from the galaxy due to it being gravitationally bound with less strength than the surrounding forces. As M90 has fallen through the Virgo Cluster toward its center, cold neutral gas has been stripped away from it thereby quenching any future star formation. The effects of ram pressure stripping on M90 are dramatically illustrated with low surface brightness tails of ionized gas revealed with deep narrowband Ha exposures, which were discovered in 2016. They have a length of 472,000 light years and currently it is unclear what the ionizing mechanism is. M89 is an unusual elliptical galaxy with a series of tidal shells and plumes revealed with long exposures. M89 was one of the first elliptical galaxies where a series of outer shells was identified in 1979 by the esteemed astronomer David Malin. This discovery was made possible through innovative techniques developed by David Malin involving enhancement and amplification of faint features on photographic plates and led to the publication of a catalogue of shell elliptical galaxies. The linear feature was first reported in 1979 to be a jet from the galaxy core but is actually a well placed tidal stream structure. The origin of the shells is not conclusive but the explanation most commonly invoked for this type of galaxy are multiple mergers with previous companion galaxies. M89 is also experiencing gas stripping but this is only observable in x-rays. Images taken with the Chandra telescope show a tail of gas, these features are a result of it also falling into the Virgo Cluster." https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1519070789410-97IOGP14GRN7N7VY03OT/NGC4410Group.jpg Galaxies - NGC 4410 Group SWO in New Mexico This rarely photographed region of Virgo contains a vast variety of galaxies. Near the centre is a relatively serene spiral galaxy pair that is collectively known as NGC 4411. Much more striking is the connected system of interacting galaxies to the north, which are collectively catalogued as NGC 4410. Much further in the distance are a few galaxy clusters, most notably Abell 1541 near the bottom left corner. Less apparent and more pervasive are hundreds of fuzzy dots in the background, these are all distant galaxies billions of light years away!   NGC 4410 is a group of interacting galaxies connected by tidal bridges and in addition to this also exhibits tidal tails and plumes. The whole menagerie of morphological features is due to the effect of gravitational interaction between the various galaxies due to their proximity to each other. This group in total contains 12 members and is located 316 million light years away and in the future is likely to merge into a single elliptical galaxy. Interestingly, NGC 4411 is only a visual pair with the galaxy on the left being 91 million light years away while the one on the right is closer with a distance of 49 million light years.

In the picture it shows outer faint details, following spiral arms and structures that reach far beyond the galaxy's brighter central regions. Including the fainter outskirts, the galaxy's diameter is well over 100 thousand light-years at M77's estimated distance, making it larger than our own spiral Milky Way.   Explanation: Big, beautiful spiral galaxy NGC 1055 is a dominant member of a small galaxy group a mere 60 million light-years away toward the aquatically intimidating constellation Cetus. Seen edge-on, the island universe spans over 100,000 light-years, a little larger than our own Milky Way. The colorful stars in this cosmic close-up of NGC 1055 are in the foreground, well within the Milky Way. But the telltale pinkish star forming regions are scattered through winding dust lanes along the distant galaxy's thin disk. With a smattering of even more distant background galaxies, the deep image also reveals a boxy halo that extends far above and below the central bluge and disk of NGC 1055. The halo itself is laced with faint, narrow structures, and could represent the mixed and spread out debris from a satellite galaxy disrupted by the larger spiral some 10 billion years ago. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1510007574335-KJM12SLV4JTXWWCPV3SI/NGC7742.jpg Galaxies - NGC 7742 Explanation: This might resemble a fried egg you've had for breakfast, but it's actually much larger. In fact, ringed by blue-tinted star forming regions and faintly visible spiral arms, the yolk-yellow center of this face-on spiral galaxy, NGC 7742, is about 3,000 light-years across. About 72 million light-years away in the constellation Pegasus, NGC 7742 is known to be a Seyfert galaxy - a type of active spiral galaxy with a center or nucleus which is very bright at visible wavelengths. Across the spectrum, the tremendous brightness of Seyferts can change over periods of just days to months and galaxies like NGC 7742 are suspected of harboring massive black holes at their cores. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1509644818035-JERWU1213J94XQSRTQW1/Abell426-NGC1275ApodCrop.jpg Galaxies - NGC 1275 Abell 426 NGC 1275 (also known as Perseus A or Caldwell 24) The Perseus Cluster (Abell 426), located 237 million light-years away in the constellation of Perseus, contains thousands of galaxies immersed in a vast cloud of multi-million degree gas. Near the cluster center is the cluster’s dominant galaxy NGC 1275 (also known as Perseus A). https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1499655661744-HNWYDYOD592IMLHTSC1G/NGC5198APOD.jpg Galaxies - NGC 5198 The Whirlpool Galaxy, also known as Messier 51a, M51a, or NGC 5194, is an interacting grand-design spiral galaxy with a Seyfert 2 active galactic nucleus in the constellation Canes Venatici. It was the first galaxy to be classified as a spiral galaxy. Recently it was estimated to be 23 ± 4 million light-years from the Milky Way,but different methods yield distances between 15 and 35 million light-years. Messier 51 is one of the best known galaxies in the sky. The galaxy and its companion, NGC 5195, are easily observed by amateur astronomers, and the two galaxies may even be seen with binoculars. The Whirlpool Galaxy is also a popular target for professional astronomers, who study it to further understand galaxy structure (particularly structure associated with the spiral arms) and galaxy interactions. "Located south of the Whirlpool Galaxy in the sky, NGC 5198 is a seemingly ordinary elliptical galaxy that was discovered in 1787 by William Herschel. Deep images however reveal a recently discovered tidal tail in addition to an outer tidal shell. The length of the tidal tail is approximately 300,000 light years and is the remains of a small galaxy that has been absorbed by NGC 5198. The linear nature of the tidal tail is indicative of a recent collision with a previous companion or satellite galaxy, which has been tidally disrupted by the larger galaxy." https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1499655853283-CDESS7VGROOHJ2LVR1X5/M51MosaicFinishedAPOD.jpg Galaxies - NGC 5198 and M51 Mosaic The Whirlpool Galaxy, also known as Messier 51a, M51a, or NGC 5194, is an interacting grand-design spiral galaxy with a Seyfert 2 active galactic nucleus in the constellation Canes Venatici.

NGC 4151 is a Seyfert galaxy and hosts one of the brightest active galactic nuclei (AGN) known at X-ray wavelengths. The supermassive black hole lying at the centre of NGC 4151 has a mass of about 50 million solar masses. NGC 4145 (Right) is around 44 million light years away and is part of the Ursa Major cluster of galaxies. This cluster contains many bright spirals for which NGC 4145 is a member. However this galaxy is considered relatively "anemic" due to the fact that unlike most spiral galaxies it does not have a lot of star formation taking place. While the spiral arms of this galaxy are punctuated by some activity, the rest of the galaxy is quite quiet. Indeed astronomers suggest that a galaxy like this will soon (in galactic terms) lose the impetus to form stars and settle down to become a lenticular galaxy. Interestingly this galaxy is interacting with another (NGC 4151). This may help maintain the star formation in NGC 4145. In fact close inspection of the nucleus of NGC 4145 seems to indicate that the tug of NGC 4151 has displaced it from its position in the center of NGC 4145. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1496344530669-SOHNB46VRRFOK2OW3LB2/NGC4145Final70.jpg Galaxies - NGC 4145 (SWO in New Mexico) This image shows the spiral galaxy NGC 4151 (Left), located at a distance of about 45 million light years from us.

This spiral galaxy spans about 100 thousand light-years and is seen almost exactly edge-on from our perspective. In fact, about 30 million light-years distant in the constellation Andromeda, NGC 891 looks a lot like our Milky Way. At first glance, it has a flat, thin, galactic disk and a central bulge cut along the middle by regions of dark obscuring dust. The combined image data also reveal the galaxy's young blue star clusters and telltale pinkish star forming regions. And remarkably apparent in NGC 891's edge-on presentation are filaments of dust that extend hundreds of light-years above and below the center line. The dust has likely been blown out of the disk by supernova explosions or intense star formation activity. Faint neighboring galaxies can also be seen near this galaxy's disk. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1495667810173-5YUF9FE2EP6MAU33MVOE/NGC+4490+Astronomy.jpg Galaxies -

NGC 3576 NGC 3576 is a minor nebula in the Sagittarius arm of the galaxy a few thousand light-years away from the Eta Carinae nebula. This nebula even received six different classification numbers. Currently, astronomers call the entire nebula NGC 3576. A popular nickname is "The Statue of Liberty Nebula" because of the distinctive shape in the middle of the nebula. The name was first suggested in 2009 by Dr. Steve Mazlin, a member of Star Shadows Remote Observatory (SSRO). Explanation: An intriguing and beautiful nebula, NGC 3576 drifts through the Sagittarius arm of our spiral Milky Way Galaxy. Within the region, episodes of star formation are thought to contribute to the complex and suggestive shapes. Powerful winds from the nebula's embedded, young, massive stars shape the looping filaments. The dramatic false-color image also highlights the contributions of hydrogen, sulfur, and oxygen, energized by intense ultraviolet radiation, to the nebular glow. But the glow also silhouettes dense clouds of dust and gas. For example, the two condensing dark clouds near the top of the picture offer potential sites for the formation of new stars. NGC 3576 itself is about 100 light-years across and 9,000 light-years away in the southern constellation of Carina, not far on the sky from the famous Eta Carinae Nebula. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1772119584885-W6SBSUU86NVI18WHOZQU/image-asset.jpeg Nebula - RCW 60 - IC 2872 ‍ ‍ RCW 60 (Gum 39) and IC 2872 (Gum 40) “Egg in a basket like the perfect puzzle pieces.” RCW 60 (Gum 39) and IC 2872 (Gum 40) are two emission nebulae in the southern Centaurus constellation, forming part of the Running Chicken nebula complex (IC 2948), about 6,500 light years away. These stellar nurseries are dense gas clouds where new stars form. RCW 60 is the bright nebula to the left, centered around the blue O6 V star HD99897. IC 2872, on the right, stands out as the brightest part of the surrounding diffuse nebula and features two or three bright lobes divided by dust lanes. The region visually resembles an egg in a basket, like fitting puzzle pieces. Imaged in RGBHa on a Planewave CDK 24 at Observatorio El Sauce, Chile.

It was given the popular name of the Toby Jug Nebula in 1979 after its appearance in colour photographs taken by David Malin at the Anglo-Australian Observatory. The central illuminating star it surrounds is the variable red giant V341 Carinae. Studies done by professional astronomers in the past attributed its formation to either mass loss or being ejected by an unseen companion. There is often difficulty in ascertaining the three dimensional structure of a nebula based on our two dimensional view of it. IC 2220 is likely to be both bipolar and biconical. Reflection nebulae surrounding red giant stars are scarce and the very few examples that are known happen to be a case of ambient interstellar matter in the surrounding region being illuminated. Despite the Toby Jug Nebula lying in a region of interstellar dust, it is unique that not only is it illuminated by a red giant but it has also been produced by it as well via mass loss. The visibility of the nebula is produced by dust grains reflecting the light of the star and it contains a mixture of elements with silicon dioxide being the most likely responsible for the reflection. Studies by professional astronomers in the past postulated that V341 Carinae was a former member of the open cluster NGC 2516 in the past. This association was based on both sharing similar distances. However in subsequent decades, better quality and more accurate astrometry data from the Hipparcos satellite showed that V341 Carinae had a much closer distance than NGC 2516 of 1200 light years while NGC 2516 has a distance of 1300 light years. However in the 21st century, more detailed observations are not exclusively reserved for the professional realm of astronomy. Through the proliferation of the internet and other technologies, it is possible for amateur astronomers to own or operate remote observatories. In fact, this image is the product of a remote observatory in Chile being operared by the image author in America. One such amateur astrophotographer called Josep Drudis who owns a remote observatory in Australia (along with a certain Don Goldman), with the assistance of his daughter Anna, serendipitously took hydrogen alpha exposures for IC 2220 in 2018 for the sake of curiosity and exploration. What was uncovered could not have been predicted, the presence of multiple overlapping arc shaped nebulosities and bubbles. Visually these are represented by the red waves of hydrogen gas visible in this deep image. Taking into account the well known history of V341 Carinae involving mass loss, these likely represent multiple episodes of mass loss prior to the event that generated the yellow reflection nebula. This is further supported by the separation of the various parts of the whole nebula. There is an absence of ionized hydrogen alpha emission coinciding with the reflection nebula as this is younger and more recent and probably not containing any hydrogen. Since V341 Carinae is known to be a red giant star with an age of 50 million years, it is not unreasonable to assume that the larger and older hydrogen bubbles represent the outer layers of the star that have been ejected in the past. As of March 2020, these enigmatic structures haven't been studied by professional astronomers yet. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1760801268764-NO0SMMJVXR48N6WLB0GC/image-asset.jpeg Nebula - Core of the Large Magellanic Cloud in RGBHa This remarkable image showcases the core of the Large Magellanic Cloud (LMC) as a highly detailed 16-panel mosaic covering more than 3.5 square degrees in the sky with 0.381 arc.sec./px. The composition beautifully reveals the wide array of gaseous colors and complex structures within the cloud, including twisting, looping, bubbling, and explosive forms. In addition to these vibrant features, the mosaic highlights numerous globular clusters and millions of stars, creating a truly stunning and captivating view of this astronomical region. The annotated version was produced by Alex Zaytsev and is a must see. <Tarantula-16pane-RGBHa-more stars-at3.jpg> Fig.1. Annotated version of the image: emission nebulae, SNR candidates and HII regions are shown in yellow ovals and markers (Tycho-2 catalog stars as also identified by the yellow markers); ISM shells and superbubbles shown in blue; star associations and star clusters shown in magenta; compact molecular clouds from various catalogs identified by white markers; compact dark nebulae are identified by the pink markers. The Large Magellanic Cloud is a dwarf galaxy and stands as one of the Milky Way's closest and most massive satellite galaxies. Visible to the naked eye from the Southern Hemisphere, the LMC appears as a hazy, luminous patch in the night sky. It is a highly dynamic region, well-known for intense star formation activity and hosting many interesting astronomical objects. Distance: Approximately 160,000 light-years from Earth Type: Dwarf irregular galaxy, with some signs of a barred spiral structure Size: About 14,000 light-years in diameter, roughly one-tenth the size of the Milky Way Star Count: Contains approximately 30 billion stars Location: Located in the southern constellations of Dorado and Mensa One of its most notable features is the Tarantula Nebula (30 Doradus) [1]: The largest and most luminous star-forming region in the Local Group of galaxies. If it were as close as the Orion Nebula), it would be bright enough to cast shadows. The LMC and the Small Magellanic Cloud (SMC) are gravitationally bound to each other and are engaged in a slow, intricate gravitational dance with the Milky Way. Recent studies indicate that the LMC may be a first-time visitor to our cosmic neighborhood, rather than a long-term satellite. This ongoing interaction is causing some of the LMC's outer halo of gas to be stripped away, though its dense core remains intact. Looking far into the future, a merger between the LMC and the Milky Way is anticipated to occur in about 2.4 billion years. SMC mosaic can be seen under [2]. The central region of the image containing Tarantula Nebula (30 Doradus) is sitting in the overlap of two LMC Supergiant Shells: LMC 3 and LMC 2 is shown in Fig. 2 (the location of other Supergiant Shells in the LMC is shown in [3, 4] and their structure described in more details in [5, 6]). This overlap is likely responsible for an extreme level of complexity if the emission nebulae structures in this region with added numerous compact neutral gas clouds sitting in front, behind and in between of them along the light of sight, resulting in beautiful patterns that require rather careful processing to preserve them in this high dynamic range scene. <Tarantula-16pane-RGBHa-more stars at2.jpg> Fig.2. Simplified annotated version of the image showing the high level structure of the region. Three sub-regions of in the center LMC 3 and LMC 2 Supergiant Shell overlap region are of particular interest here as shown in the cropped and cropped annotated versions or the original image shown in Fig. 3, Fig. 4 and Fig 5: Fig. 3 shows the area containing Tarantula Nebula (30 Doradus) and its immediate vicinity populated with numerous star clusters and star associations. The supernova remnant SN1986A [7] is also sitting on the boundary of LMC-N157 [8] HII region of unusual horseshoe shape in the upper left corner. Fig. 4 shows the area of the original image sitting above the one shown in Fig. 3, dominated by the DEM L261 [9] HII region hosting several star associations and the LMC-N158 [10] HII region on the right side of the cropped image that has multiple star clusters perfectly framed by the walls of the HII region. There are rather peculiar “double wall” ripple-like diffuse structures in the lower left corner of the frame. Fig. 5 continues the scan of the original image going in upward direction showing the area filled with multiple HII regions complete with several stand-alone SNRs in the middle top portion and the upper right corner of the frame.

Image Processing and Data Collection The image was processed and calibrated by Mark Hanson using advanced methods to ensure exceptional clarity and detail. The data for this mosaic was gathered by Hanson, Mazlin, Parker, and Forman in 2025. Observations were made using a 24-inch Planewave CDK telescope with an f/6.5 configuration, mounted on an L600, and a Moravian C5 camera located at El Sauce, Chile. The final mosaic consists of 16 panels, captured in Red, Green, Blue (RGB), and Hydrogen-alpha (Ha) bands, with binning at 2x2. In total, 960 R, G, B, Ha frames were taken, resulting in 100 hours of cumulative observation time so far, OIII and SII to follow. Enjoy this breathtaking view!

It is quite a dynamic and colorful area in the Southern sky. We have also added a labeled version for you to gaze at. NGC 2726-27 and IC 4812 - these most prominent intense blue areas (left center) are reflection nebulae which are clouds of interstellar dust lit up by the bright nearby stars. You can also see them illuminating areas quite far outside the actual Nebula’s themselves. NGC 2726-27 has the presence of a widely spaced double star, while IC 4812 features a much closer double star with two sets of diffraction spikes, indicating the presence of double star BrsO 14. Just to the left of NGC 2726 is a very exciting area, NGC 6729 a reflection/emission nebula located some 424 light-years away. This object is also a variable nebula, and the Coronet Cluster also known as R CrA. It was discovered by Johann Friedrich Julius Schmidt in 1861.This fan-shaped nebula opens from the star R Coronae Australis toward the star T CrA to the south-east. R CrA is a pre-main-sequence star in the Corona Australis molecular complex, one of the closer star-forming regions of the galaxy. Bernes 157 and SL 41 are areas called Dark Nebula interstellar clouds that are dense enough to obscure the light from behind. Bernes 157 (DN) is a boomerang shaped dark nebula that is 520 light years away. Herbig-Haro (HH) objects, named after astronomers George Herbig and Guillermo Haro, are high-velocity jets emitted by young stellar objects that interact with surrounding gas, generating shock waves and illuminated arcs. These jets can reach speeds between 100 and 1000 km/s, forming distinct luminous fronts within nebulae that persist for only a few thousand years. This image contains 35 examples of Herbig-Haro objects, HH 82 A-B, 96, 97, 98, 99 A-B-C, 100, 101, 101 S-N, 104, 104 D-C, 729 A-B-C, 730 A-B, 731 A-B, 732 A-B-C, 733, 734 A, 735 A-B, 736, 860, 861 A-B, 862. These objects are often mislabeled among amateur and even professional data, which makes it challenging to get a good map of them and their true locations, including several that remain unnamed or unclassified in literature. NGC 6723 (right center) colorful gem like globular cluster really compliments this field of view. This globular cluster cataloged as Dunlop 573, was discovered by James Dunlop in 1826 from New South Wales, Australia. Appearing near Corona Australis in Sagittarius, and it is located about 30,000 light-years away, beyond the Corona Australis dust cloud. There are quite a few small background galaxies present here as well. The labeled version shows all these objects and more. There are 3 areas: A, B and C that will require further study as they are unclassified or unnamed.

Its apparent diameter in the sky is 0.5 deg which corresponds to a linear size of about 12 ly at that distance. Numerous neutral gas clouds that are located at the distances as close as 850 ly belonging to the Serpens–Aquila Rift [9, 10] which extends over the range of distances from 750-1650 ly and alters the appearance of RCW 174 significantly in the visual spectrum compared to near-IR views [3, 4]. Several sub-regions of RCW 174 are of particular interest, such as the dense area surrounding star UCAC4 439-077030 [11] for which the Gaia DR3 [12, 13] parallax based distance estimate is 1661 ± 24 ly, so it is likely physically associated with the RCW 174 region. The Spitzer IR image [3, 4] reveals a system of bow shocks in the immediate vicinity of UCAC4 439-077030 [11], as illustrated in Fig. 1, even though its measured proper motion of 6.75 mas/yr corresponds to “only” 16 km/s per second of the linear speed, and the direction of motion is pointing away from those bow shocks. Thus, those shock fronts could be associated with one of the dimmer stars found in the vicinity. Two outflow structures MHO 3284 [14], MHO 3285 [15] are identified in this area in [16, 17] without pointing to a specific source for them. RCW 174 (Sh2-64, LBN90 and W40) HII region in Serpens Wonderful Description from: Alexander Zaytsev The subregion of interest here is near the center of NAME W 40 star cluster [18] / LBN 028.77+03.43 HII region [19] that are hosting several OB stars and numerous young stellar object candidates embedded into a dense portion of a molecular cloud [20-22]. Once again the Spitzer IR image [3, 4] reveals a complex internal structure of that cloud, with a lot of density variation that is practically invisible in the visual spectrum - as shown in Fig. 2. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1752853919463-D5UXYYX7MW9F83XDXG8X/image-asset.jpeg Nebula - RCW 105 or Gum 51 RCW 105 or Gum 51 RCW 105 (Also catalogued as Gum 51 ) is an emission nebula in constellation Norma. The nebula is surrounded by numerous small molecular clouds and is likely embedded in the compact OB association R105. The estimated distance for the R105 association is about 1580 parsecs and its age is 12.8 million years. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1750160642162-CVRC5VJBP39J9VAH9KSB/image-asset.jpeg Nebula - Batcave in Centaurus by Zaytsev and Hanson Batcave in Centaurus by Zaytsev and Hanson The HII region RCW 79 (GUM 48c, GRS G308.60 +00.60) [1, 2] embedded into a massive molecular complex of Centaurus has been studied extensively [3, 4], yet it remained a rarely imaged target which is often overlooked in favor of its neighboring RCW 78 (GUM 48b) HII region [5, 6]. Here we present a close-up look at RCW 79 with Chilescope Telescope #1 system that reveals a remarkably complex structure of the rim of this HII region, filled with lots of small dark nebulae, one of which resembles a certain character of popular fiction to such an extent that it prompted the choice of name for the scene [7, 8]. Fig. 1 and Fig. 2 point out the most notable features found in the rim of RCW 79. WIth distance to this HII region estimated as 5.3 ± 0.4 kpc [3, 4] the characteristic size of the HII region itself is only about 60 ly, the linear size of pillars 1 and 2 identified in FIg. 1 and Fig. 2 is about 1.3 ly, and the wingspan of the “Batman figurine” is about 13 ly. An open cluster Cl VDBH 151 [9] with measured parallax of 0.176 ± 0.013 mas is likely physically sitting inside the inner volume of the HII region, as its distance estimate of 5.7 ± 0.4 kpc based on that parallax is consistent with the distance estimate to RCW 79. Another visually striking feature of this scene is the “dark stream” crossing the area from top left side to lower central side consisting of multiple dark clouds elongated in the direction of the “stream”. This creates an illusion of the inner volume of RCW 79 to be lit from some external source at the top left side. The 4.5 mkm and 8 mkm IR imaging of this target by Spitzer [10-13] reveals more structures inside the rim of RCW 79, but most of the peculiar features listed above aren’t easily identifiable in IR images. Fig. 3 shows the Spitzer IRAC HEALPix survey color data [14] for the FOV of the image. As pointed in [9, 10] the RCW 79 remains an active star formation region with age estimated at 1.9 Myr [10, 11]. A compact (“only” about 9 ly across) HII region IRAS 13374-6130 [15] is emerging around one of those star formation sites, which is likely to open into the inner volume of the RCW 79 later during its evolution, resulting in a similar configuration as currently observed for Gum 48d - an older (about 4 Myr old) and less distant HII region in Cen [16, 17]. Overall, the RCW 79 turned out to be full of unexpected and visually striking features that deserve further study with large aperture systems.

The area also contains reflection nebulae VdBH 60a placed at an estimated distance of 1.9 kpc [8] and VdBH 60b both located at the “tip” of the elephant trunk nebula, as well as VdBH 60d and VdBH 60c reflection nebulae in the upper left corner.The angular size of the FOV in this image is 18’17” (side of the square) which for the distance of 1.9 kpc corresponds to the linear size of about 33 ly. Both earlier [3] and later [4, 5] studies conclude that the Stock 16 cluster has formed on the outer edge of the elephant trunk nebula which used to be larger prior to formation of the cluster. It is further derived [3] that that original (larger) elephant trunk nebula suffered an implosion triggered by the intense radiation from preceding generation of the OB stars from a cluster that is now dispersed over the larger area of the HII region, thus resulting in creation of the currently observable scene. It is also concluded that RCW 75 remains an active star formation region and that the site of next generation of stars “should lie in the dense dust clouds located along the ionization-bound edge of the complex” [3] pointing to the central stars of the four VdBH 60a-d reflection nebulae as possible newly formed objects. The image shows the unprecedented level of details in both dark nebulae in the middle and also in the “veil” preceding the ionization-bound edge of RCW 75 complex on the right of the trunk nebula, revealing many ghostly features there. A considerable amount of details is revealed in the part of the nebula complex on the left of the trunk nebula as well.

It is embedded in the Cometary Globule CG 12 and lit by a double star H4636 which are type B4 and B7 stars. Cometary globules are interstellar clouds with comet-like morphology, consisting of compact, dusty, and opaque heads and long, faintly luminous tails. Reflection nebulae are clouds of gas and dust that reflect the light from nearby stars. The starlight scatters through the gas and dust like a flashlight beam shining on mist in the dark and illuminates it. Imaged in LRGB on our Planewave CDK 700 at Observatorio El Sauce, Chile.

Many dark nebulae, open star clusters, and planetary nebulae are present in the scene, yet two most intriguing features found here are both associated with LHA 120-N 144 [3] HII region as highlighted in the cropped version of the image shown in Fig. 1: A faint elliptical arc that is fitted well by an ellipse with axis lengths of 360 ly x 940 ly (at the estimated distance to LMC of 158 kly) that is visible on one side of the region and marked as X1 in Fig 1. A set of compact shells approximately 56 ly across surrounding the red supergiant star HD 269551A [8] (which forms a binary system together with HD 269551B [9]) - marked as X2 in Fig 1. The HD 269551A [8] is the second largest star in the LMC with the physical radius estimated at 1439 solar radii (measured using photometric method based on data obtained from [10, 11]) which places it in TOP 15 on the list of the largest stars known to date. The structure of the compact nebula - multiple contric shells surrounding the HD 269551A [8] - suggests a physical connection to that star. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1743348619134-06N3FXNF4X9315MJL5HH/image-asset.jpeg Nebula - Gum 37 Gum 37 Gum 37, also known as RCW 54c, is a diffuse HII emission region located in the southern constellation of Carina, this region is often overlooked due to the brighter Statue of Liberty nebula in close proximity. Gum 37 includes the "Southern Tadpoles". The "tadpoles" refer to the elephant trunk-like tendrils of interstellar gas and dust, remnants of star formation. That giant "ear" at the top of the image is believed to be a planetary nebula or a remnant of the molecular cloud that formed the cluster. There is limited information available on this deep sky object The thin finger-like structures throughout the nebula are what immediately draws the eye in. These are highly compressed structures of molecular hydrogen that present a certain duality. On the one hand, the collapsing hydrogen is providing conditions for new star formation. On the other hand, the ultraviolet radiation from those newly formed stars is slowly eroding and destroying the nebula from within. Over time, this process will make the nebula disappear completely.

PCG 11 (PHR 1633-4928) Wolf-Rayet star and associated ring nebula [4-6] that has been named “The Jaws” by Logan Carpenter [7] who first introduced it to Astrobin back in 2023 [8, 9]. The earlier image obtained for this scene in H-alpha only with the same Chilescope T1 system back to 2024 is available under [10]. Many other diffuse structures and dark nebulae are visible across the frame, emphasized even better in the color compared to the H-alpha only view. Fig. 1 shows a cropped version of the image centered on WRAY 15-1508 at 200% of original resolution. According to [11] it is identified as a flat bipolar outflow planetary nebula, yet many additional structural features are revealed in this image, including a disruption in the “arms” of the nebula in the middle likely hinting the presence of a neutral gas disk in the middle. The distance estimate to WRAY 15-1508 given in [12, 13] based on Gaia EDR3 [14, 15] data is 2177 ± 233 pc, so the linear size of the “arms” of the nebula is about 0.33 px x 0.39 pc, and the gap in the middle is only 0.027 pc = 5.6 kAU wide. Fig. 2 shows a cropped version of the image centered on PCG 11 at 150% of original resolution. Based on the distance estimate to PCG 11 of 4100 ± 400 pc given in [5, 6] the linear size of the shell of the nebula is about 1.50 pc x 1.97 pc and the characteristic size of non-uniformities in the rim is just about 0.22 pc. According to [5, 6] the explanation for thee unusual disruptions of the ring structure on the inner side of the rim of PCG 11 is as follows: "Material at the inner boundary of that enveloping material suffers Rayleigh-Taylor instability. This appears as a highly regular scalloping of the inner margin of the nebulous Ha ring, defined by fingers of infalling ionized matter. There is a very well-defined wavelength for this phenomenon in PCG 11 and it is observed around the entire nebula rim." https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1741616971113-JN8A7GTBWL46MFFKED4K/image-asset.jpeg Nebula - Sharpless 293-295 "Falls of Blue" These spectacles of the universe Sh2-293 and SH2-295 look like blue waterfalls glistening and pouring down. Title: “Falls of Blue” Sharpless 293-295 The image is showing the region of sky off one of the wings of IC 2177 (Gum 2, RCW 1, Sh2-292, Seagull) [1] nebula located on the border of Monoceros and Canis Major constellations containing two HII regions (as shown on annotated version of the image in Fig. 1): Sh2-295 (LBN 1035) [2] in the lower left corner of the image, with the bright central star V* FZ CMa (HD 52942, a spectroscopic binary) [3] associated with the reflection nebula VdB90a. The V* FZ CMa itself is surrounded by the reflection nebula GN 07.00.3 [4]. Another reflection nebula VdB90b sitting on the boundary of this HII region is excited by the BD-11 1761 [5] - a star situated in the wing of the Seagull nebula outside of the FOV. The distance estimate to Sh2-295 given in [6, 7] is 2.28 ± 0.65 kly while the distance to V* FZ CMa based on Gaia parallactic measurements is 3.33 ± 0.16 kly. Sh2-293 (LBN 1030) [8] with bright central star HD 52721 (BD-11 1747, HIP 33868, GU CMa) [9] (a quadruple star system [10] with two other components identified as HD 52721A [11] and HD 5272B [12]) associated with reflection nebula VdB88 (upper right corner of the image). The distance estimate for Sh2-293 given in [6, 7] is 2.45 ± 0.65 kly while parallax based distance estimate to its main ionizing star HD 52721 using Hipparcos astrometric data [13, 14] is yielding 1.45 ± 0.77 kly with is still compatible with Sh2-293 distance estimate given a large systematic error on HD 52721 distance estimate (1.2 mas parallax error even after the reduction [13, 14]). Both HII regions are ionized by stars belonging to the CMa OB1 star association [15, 16] containing the CMa R1 association of reflection nebulae spanning across the region of the sky 2.5 deg x 1.6 deg across [17, 18]. The CMa R1 is nested in the “CMa shell” likely created by a sequence of supernova explosions that happened 1- 6 Myr ago [19, 20]. Fig. 2 shows the annotated version of the image with parallax data (in units of mas) available from the Gaia DR3 XPSD DB [21, 22]. Taking the distance to the scene at about 3 kly, the horizontal edges of the FOV correspond to 32.3 ly and 24.4 ly of linear distance. The other components of Seagull nebula such as IC 2177 and NGC 2327 are located at a significantly larger distance of 3.65 - 3.80 kly, so both Sh2-293 and Sh2-295 may be overlapping structures with respect to that larger CMa R1 scene. Great many compact neutral gas clouds can be identified on the background in the FOV: 32 molecular clouds from MWISP survey [23, 24] alone are in it, including [KKY2004] 6 molecular cloud [25] sitting on the right boundary of Sh2-295 HII region and likely responsible for the formation of the multilayer structure of the wall there. Numerous compact neutral gas clouds are also forming a rather complex structure of the wall of Sh2-293 HII region presented here in unprecedented level of details. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1740937768163-YQXZCPKLAA5CJ00TMM9N/Chamaeleon+Molecular+Cloud+Thumb.jpg Nebula - The Chamaeleon complex Ced 110 The Chamaeleon complex is a large star forming region (SFR) that includes the Chamaeleon I, Chamaeleon II, and Chamaeleon III dark clouds. It occupies nearly all of the constellation of Chamaeleon and overlaps into Apus, Musca, Carina and Octans. Chamaeleon 1 is one of the nearest active star formation regions and is around 700 light years away. Chamaeleon 2 contains over 40 X-ray sources while Chamaeleon 3 appears to have no star formation taking place.

Also known as the "Skull and Crossbones Nebula" is located in the constellation Puppis. Numerous stars and clusters come together to make this stunning stellar portrait. One of the most notable clusters within NGC 2467, known as Haffner 18, houses around 50 stars—most are high-mass, but have already begun the transit into the celestial afterlife. They certainly help shape the pillars of gas and dust, but their role is negligible compared to that of HD 6315 located in the center of NGC 2467. This gargantuan star does most of the work. Its outbursts, ranging from flares, to coronal mass ejections and such, eject vast quantities of radiation into the nebular material, which has a carving effect. The dark splotches all around and in the nebula are Bok Globules. Within these regions, dust is packed together so tightly, light from embedded stars can’t break through. 75 Hours of exposure https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1737157388256-WOWMBSD6D243KT9SOF21/image-asset.jpeg Nebula NGC 1833 and its surroundings in the LMC by Zaytsev and Hanson Here is a close look at the part of the LMC 8 supergiant shell [1-4] located South-West of the Large Magellanic Cloud (LMC) containing the LH24 OB star association [5] with NGC 1833 emission nebula [6] and NGC 1837 open cluster [7] enclosed within obtained with the Chilescope T1 system (ASA Ritchey-Chretien RC-1000: D=1m, f/6.8). Manually annotated version of the image is shown in Fig. 1. A wider angle view of this region near the LMC was also obtained earlier using the Chilescope T3 system (ASA-N D=0.5m, f/3.8) [8], yes significantly more details of internal structure are revealed here for the three main diffuse structures: NGC 1833 [6] showing a compact (8.4 ly across by the longer axis at estimated distance to LMC of 158 kly) neutral gas feature in the inner volume of the nebula shown in Fig. 2. DEM L 75 HII region [9] and nearby emission nebula complex also featuring another compact (5.8 ly across by the longer axis at estimated distance to LMC) neutral gas feature appearing to be fully surrounded by ionization fronts as shown in Fig. 3. A peculiar bipolar LHA 120-N 191 object [10, 11] consisting of a compact HII region on one side and a more diffuse emission nebula on the other side shown in Fig. 4. The range of linear scales for substructures for this region is 6-50 ly - estimated based on distance to the LMC. According to [10, 11] the start population physically associated with the compact HII region LHA 120-N 191A are “only” 3-8 Myr of age which accounts for the relative compactness and high density of this region. Fig. 5 shows the annotated cropped view of the central part of the image that contains besides NGC 1833 [6] and NGC 1837 [7] a peculiar elliptical asterism situated around SP77 40-9 [12] long-period variable candidate star that is about 67 ly away based on Gaia DR3 parallax measurements [13, 14]. The asterism was first identified in the Chilescope T3 image [8] and given a reference name of “LMC SH8 X1”. Remarkably so, the structure appears even more apparent in the Chilescope T1 image, and also more details of the background diffuse structures are visible in it as illustrated in Fig. 6 showing the region of interest at 200% of original resolution: Tiles (a) and (b) show the region in HOS colors with and without elliptical overlays showing where the main concentration of point-like sources forming the asterism. The dimensions of the overlays are 367px x 326px (in 100% of original resolution) = 100 arc.sec x 89 arc.sec (eccentricity 0.46) for the outer shell, and 290px x 257px (in 100% of original resolution) = 79 arc.sec x 70 arc.sec (also of eccentricity 0.46) for the inner shell. Tile (c) shows the same HOS color version with an overlay showing available parallax data based on Gaia DR3 XPSD DB [15, 16]. Only few stars in the elliptical band indicated have meaningful (positive) parallax values - these are shown with red underline - and these parallax values are in the range of 0.011 - 0.082 mas corresponding to 40 - 300 kly distance. The parallax of the central star SP77 40-9 [12] is measured as 0.0485 ± 0.0125 mas [17] corresponding to 67 ± 17 kly. Tile (d) shows the same scene with all diffuse components removed to emphasize the point-like sources component. Tiles (e) and (f) are showing the same scene in B&W with the attempt to run the aperture photometry analysis procedure with PixInsight on it. Most of the faint sources in the asterism aren’t picked up by this procedure. The angular diameter of the elliptical shells of 70-100 arc.sec correspond to 23 - 32 ly of linear size at the distance of 67 kly or 54 - 77 ly - at the distance to the LMC of 158 kly. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1734024884795-M0QNXCFGCCQ4E66SZZE2/image-asset.jpeg Nebula - NGC 2018 NGC 2018 This Chaotic Cluster of Gas an area within the Large Magellanic Cloud that is very rarely imaged, NGC 2018 is an emission nebula with a star cluster.

It is the largest and most complex star forming region in the entire galactic neighborhood. Located in the Large Magellanic Cloud, a small satellite galaxy orbiting our Milky Way galaxy, the region's spidery appearance is responsible for its popular name, the Tarantula nebula. This tarantula, however, is about 1,000 light-years across. Were it placed at the distance of Milky Way's Orion Nebula, only 1,500 light-years distant and the nearest stellar nursery to Earth, it would appear to cover about 30 degrees (60 full moons) on the sky. Intriguing details of the nebula are visible in the following images shown in colors emitted predominantly by hydrogen, oxygen and sulfur as well as red, green and blue. The spindly arms of the Tarantula nebula surround NGC 2070, a star cluster that contains some of the brightest, most massive stars known, visible in this butterfly like section of the image. Since massive stars live fast and die young, it is not so surprising that the cosmic Tarantula also lies near the site of the closest recent supernova. 3 versions of this nebula, all quite different.

Since most of the diffuse structures in this frame belong to the LMC, the linear size of the sides of the image of 51.9 arc.min by 36 arc.min can be estimated as 1.82 kly by 1.26 kly at the distance to LMC taken as 158 kly. Fig. 1 shows the upper left corner of the original image containing Theta Dor and multiple HII regions, SNRs, and star clusters of which the most prominent ones are: A group of two adjacent HII regions DEM L 107 [3] and MCELS L-152 [4] in the vicinity of Theta Dor, containing what appears to be several neutral gas clouds with ionization fronts on the periphery (marked as (a) - (c) in Fig. 1). A pair of HII regions DEM L 99 [5] and DEM L 90 [6] less complex on internal structure. A pair of compact HII regions LHA 120-N 26 [7] and LHA 120-N 27 [8]. Compact SNR [FHW95] LMC B0512-6710 [9], Open star clusters BSDL 850 [10], KMHK 616 [11], and 2MASX J05113171-6658315 [12] of which the latter much resembles a globular cluster but appears to be fully resolved up to the core and is accompanied by a background galaxy 2MASS J05114560-6657411 [13]. It appears that Theta Dor has extensive nebulosity around it with a radially symmetrical component which might be physically related to that star. Since the estimated distance to Theta Dor is 490 ly, it is possible that there is an overlap of much closer nebular on top of more distant structures belonging to the LMC here. Fig. 2 shows the lower left portion of the of the original image containing the other two emission nebulae complexes connected to star associations NGC 1869 [14], NGC 1871 [15], and NGC 1873 [16] containing what appears to be two ionization fronts (marked as (a) and (b) in Fig. 2). In between of the two emission nebula complexes there appears to be a spherical region that could be identified as SNR LI-LMC 642 [17]. The other two prominent structures here are an emission nebula identifiable as LHA 120-N 30D [18] and a neutral gas cloud [LLS2019] 18 [19] sitting in the gap separating it from the outer wall of the nebula surrounding NGC 1871 star association. Fig. 3 shows the lower right portion of the of the original image in which the most noticeable objects are: Spread-around globular cluster NGC 1846 [20]. Open star clusters NGC 1842 [21] and NGC 1844 [22] that both resemble globular clusters, but getting resolved nearly to the core. Compact SNR B0509-67.5 [23-25] also known as “Red Bubble” [26] that much resembles a planetary nebula but shows the characteristic fine structure of shock fronts on its boundary in the image obtained by the HST and Chandra [27-29]. Small open star cluster H88 188 [30]. The estimated physical diameter of the “Red Bubble” SNR is 23 ly [26] and the age estimate for it is only 400 ± 120 years old [24, 25] which makes it one of the youngest known SNRs in the radius of 200 kly and also one of just a few SNRs for which the light echo age was ever measured [31, 32]. While the SNR B0509-67.5 might be the object that received most attention in the literature so far in this entire region, the structure of the nebule surrounding Theta Dor and NGC 1871 association deserves further exploration with large aperture instruments. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1728763158232-XQ1XFC9BF3JPU5DOBO2B/image-asset.jpeg Nebula - LHA 120-N55 emission nebula Title: LHA 120-N55 emission nebula complex by Zaytsev and Hanson North-East of the Large Magellanic Cloud (LMC), a peculiar combination interstellar shell, emission nebulae, and a collection of shock fronts forming a structure that we called earlier a “Flying Owl Nebula” is located, for which an earlier image was obtained using the Chilescope T3 system (ASA-N D=0.5m, f/3.8) [1]. Here we present the close-up view on one of them - the LHA 120-N55 emission nebula complex / N55 molecular cloud of the LMC [2, 3], obtained with the Chilescope T1 system (ASA Ritchey-Chretien RC-1000: D=1m, f/6.8) comprised of the following tightly coupled structures - also shown in Fig. 1: LHA 120-N55A star forming region [4], DEM L 228{a, b} HII regions [5] arranged into a bi-polar shape with a bridge in the middle, that appears to be a nebula associated with WBBe LH 72 13 Be star candidate [6]. Fig. 1. The central part of the image containing the following structures: (a) LHA 120-N55A star forming region [4] and (b) DEM L 228{a, b} HII regions [5] arranged into an unusual bi-polar shape with a bridge in the middle, that appears to be a nebula associated with WBBe LH 72 13 Be star candidate [6]. Shown at 100% of the original image resolution. As LHA 120-N55 physically belongs to the Large Magellanic Cloud (LMC) [2, 3], the linear size of the side of the image of 18.5 arc.min can be estimated as 650 ly at the distance to LMC taken as 158 kly. Fig. 2 shows the part of the image containing the DEM L 228{a, b} HII regions and WBBe LH 72 13 Be star candidate at 150% of the original resolution.Two most striking features here is the spiral structure of the formed out of neutral gas clouds inside the DEM L 228b region and the “bridge” connecting the DEM L 228{a, b} regions of the estimated physical length of about 13 ly at the distance to the LMC. There appears to be a neutral gas tendril present inside that compact nebula extending from the central star to the periphery of the nebula as well. Fig. 2. Part of the original image containing the DEM L 228{a, b} HII regions [5] and WBBe LH 72 13 Be star candidate [6]. Shown at 150% of the original image resolution. Fig. 3 shows the part of the image containing the LHA 120-N55A star forming region [4] hosting the LH 72 OB star association [7, 8] and a rather beautiful collection of compact neutral gas clouds, ionization fronts and shock fronts. The brightest stars of the LH 72 appear to have shock fronts or compact toroidal diffuse structures associated with them. The linear scale estimate for both structures is in the 9.4-9.7 ly range given the distance to the LMC. Fig. 3. Part of the original image containing the LHA 120-N55A star forming region [4], shown at 200% of the original image resolution. Shock front (a) and toroidal diffuse structure (b) associated with bright stars of the LH 72 OB association [7, 8]. The highest resolution image available up to date for this OB association is one obtained by the Hubble Space Telescope (HST) WFC2 / WFC3 instruments using Ha, UV and visual spectrum data [9]. Fig. 4 shows the cropped version of the original image at 200% resolution with the HST image [9] added as a semi-transparent overlay thus making it easy to identify all of the small structural features of this region detected in both images. This entire nebula complex is undoubtedly a good candidate for study with even larger apertures, particularly for the interior part of the LHA 120-N55A region and the compact nebula surrounding the WBBe LH 72 13.

Today we know this light was from a supernova, or exploding star, and record the expanding debris cloud as the Veil Nebula, a supernova remnant. This sharp telescopic view is centered on a western segment of the Veil Nebula cataloged as NGC 6960 but less formally known as the Witch's Broom Nebula. Blasted out in the cataclysmic explosion, the interstellar shock wave plows through space sweeping up and exciting interstellar material. Imaged with narrow band filters, the glowing filaments are like long ripples in a sheet seen almost edge on, remarkably well separated into atomic hydrogen (red) and oxygen (blue-green) gas. The complete supernova remnant lies about 1400 light-years away towards the constellation Cygnus. This Witch's Broom actually spans about 35 light-years. The bright star in the frame is 52 Cygni, visible with the unaided eye from a dark location but unrelated to the ancient supernova remnant.   https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1727019204817-MI24Z867WDD3440PJOUU/SH2-234+V2AOPDsmall.jpg Nebula - SH2-234 - IC 417 - Spider Nebula (SWO) IC 417 , sometimes known as Spider Nebula , is a large visible nebula visible in the constellation of Auriga ; it is linked to Stock 8 and is home to important star formation processes. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1724929775026-DV3N6D9J34SNX14PVD2D/image-asset.jpeg Nebula - Ced 90 or Sh2-297 in the Seagull Nebula Ced 90 or Sh2-297 in the Seagull Nebula Ced90 or Sh2-297 is an emission nebula in the constellation Canis Major. The region was catalogued in 1959 in the extended seconded edition of the Sharpless catalogue. This area of Canis Major is a very active area of new star formation. Studies in 1988 found that the bright star illuminating the nebula was 8th magnitude HD 53623 / HIP 34178 with spectral class B1II/III. Later in 2004 it was shown that there was embedded a cold but massive Young Stellar Object or YSO within Sh2-297 near the edge of one of the dark rifts. This object has been observed in the far-infrared, but it is so deeply embedded in an interstellar cloud that it is undetectable in shorter wavelength observations such as the Two Micron All Sky Survey (2MASS), leading it to be originally named “Unidentified young stellar object 1” or UYSO-1. It was further revealed that this unseen stellar source produces a carbon monoxide (CO) bipolar outflow with a total mass of 5.4 M☉ solar masses, while the surrounding extended envelope weighs 30 M☉–40 M☉. Some 96 other YSOs have been discovered to be part of Sh-297, having a mean age of one million years and range in masses between 0.3 M☉ and 2.0 M☉.[1] Many variable stars are also assigned with this nebula complex, including the three brightest: MW Ori, TT Ori and V559 Ori. Distance is estimated between 1.0 and 1.4 kpc. (3,300–4,600 ly.),[1] averaging 1.2 kpc. or 3,900 ly. This region was catalogued as part of the major clustering of reflection nebula as CMa R1 by van den Bergh in 1966.Reflection nebulas were identified on blue plates of the Palomar Sky Survey, with positive confirmation made by checking nebulosity on the red plates. It was again later catalogued as LBN 1037 or LBN 225.27-02.42 SWO at Dark Sky New Mexico 17”CDK Ha 630, Luminance 300, Red 280, Green 280, Blue 280 Enjoy, Mark https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1723651803861-8TX8PGINN4102TP387ZD/S-300small.jpg Nebula - Veil Nebula Simeis 3-210 (SWO) Veil Nebula (A) = Simeis 3-210 20 53 07 +29 39.0 Simeis 3-210 is a long, thin filament at the extreme southern end of the Veil Nebula and is virtually unknown (not listed separately in SIMBAD), although it is outlined on the U2000 and Millennium star atlases. Although much fainter than the other main sections of the Veil, Simeis 3-210 was easily picked up at 105x using an OIII filter as it passes through mag 6.4 HD 198976. This narrow strand is extended N-S at least 20' with the northern half mainly consisting of an elongated patch (~3'x1'), centered about 6' NNE of the bright star. The southern section is a very dim filament beginning at the mag 6.4 star though it brightens somewhat ~10' SSW of the star. There also appears to be some streaky, detached nebulosity just west of a mag 7.7 star further south, extending the total length to 25'-30'. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1719838434630-EPJI1Z8BK12212D8J3PX/image-asset.jpeg Nebula - PP 81 Cometary Reflection Nebula PP 81 - Cometary Reflection Nebula In Barnard 228 a large molecular cloud in the constellation Lupus resides eerie but wonderful cometary reflection nebula hiding in the dark expanse of gas also called “The Dark Wolf Nebula”.

Open cluster NGC 3293 is located in the constellation Carina, lies at a distance of about 8000 light years, and has a particularly high abundance of these young bright stars. A study of NGC 3293 implies that the blue stars are only about 6 million years old, whereas the cluster's dimmer, redder stars appear to be about 20 million years old. If true, star formation in this open cluster took at least 15 million years. Even this amount of time is short, however, when compared with the billions of years stars like our Sun live, and the over-ten billion year lifetimes of many galaxies and our universe. Pictured, NGC 3293 appears just in front of a dense dust lane and red glowing hydrogen gas emanating from the Carina Nebula. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1715173423572-DCZ0AUSUYQMQSP987ZV1/image-asset.jpeg Nebula - Flying Owl Nebula Flying Owl Nebula of the LMC by Zaytsev and Hanson The area shown in this image is a part of LMC-4 superbubble is located North-East of the Large Magellanic Cloud (LMC) contains a rich collection of HII regions and supernova remnants (SNR) fitting in between the NGC 2041 globular cluster [1] and the NGC 2030 (also known as LMC N63 or LHA 120-N63) HII region [2]. The positioning of this area with respect to the main body of the LMC is illustrated by the wide angle image available under [3], where it can be identified by a quadrilateral connecting the following objects: ● LHA 120-N64A emission nebula [4] / DEM L 253 HII region [5], ● NGC 2030 [2] / SNR B0535-66.0 [6], ● LHA 120-N55A star forming region [7] / DEM L 228b HII region [8], ● NGC 2041 [1]. The size of the side of the image of 64 arc.min corresponds to 2.9kly at the distance to LMC taken as 158kly. Given the size of this subregion of the LMC, there are numerous objects of particular interest found in it, of which those occupying the upper segment of the image are listed and shown in Fig. 1.

Located in Carina nebula, close to the more famous Gabriel Mistral Nebula and Gem Cluster. Wolf-Rayet stars are hot massive stars that are experiencing a normal evolution for very large stars where they lose orders of magnitude more solar mass each year in comparison to our Sun. They form a very strong solar wind that interacts with the interstellar medium, often producing "bubbles", as shown here. Wolf-Rayet stars are very rare stars in our Milky Way galaxy. There are approximately 500 or so of these Wolf-Rayet stars in our Milky Way galaxy, so that is not very many. Imaged with a 24” Planewave telescope with Sbig 16803 using LRGBHAO2S2 filters.

Lightyears of woven dust and gasses like a priceless work of art. It’s intricate details of shapes from pillars, mountains, caverns, and wispy intricate fragments. The colors are impressive as well, the blues from Oxygen, the reds from Hydrogen and the yellows from Sulfur. All together they look as if you’re peering into a kaleidoscope. Quite the sight. NGC 6357 also known as the Lobster Nebula and War and Peace Nebula is a large emission nebula located approximately 5,900 light-years away in the constellation Scorpius. The nebula contains many proto-stars (which are very young stars that are still gathering mass from their parent molecular cloud). These stars are shielded by dark discs of gas and wrapped in expanding "cocoons" or expanding gases surrounding these small stars. The nebula contains many unusually massive stars whose interstellar winds, powerful magnetic fields, gravity, and radiation pressures are carving complex structures in the surrounding dust and gas. The hot, luminous O-type stars are the main ionizing source in the area. The nebula hosts several massive young star clusters and is one of the most prominent star-forming regions in the southern sky. Open star cluster Pismis 24 near its center (left center in this image) is one of the brightest stars in the cluster, Pismis 24-1, was thought possibly to be the most massive on record, approaching 300 solar masses, until it was discovered to be a multiple system of at least three stars; component stars would still remain near 100 solar masses each, making them among the more massive stars on record.

There are approximately 500 or so of these Wolf-Rayet stars in our Milky Way galaxy, so that is not very many. These stars are evolved, massive stars that have completely lost their outer hydrogen and are fusing helium and heavier elements in the core. WR 102 is in its final stages of nuclear fusion, near or beyond the end of helium burning. It’s likely it only has a few thousand years to exist before it explodes. WR102 is 200,000 degrees hotter than our sun and the hottest star ever recorded. These fascinating astronomical objects provide a glimpse into the extreme conditions of our Milky Way galaxy.

It is part of the RCW Catalogue, which lists H-emission regions in the southern Milky Way from Rodgers, Campbell & Whiteoak. RCW 89 is an emission nebula that contains a young supernova remnant and one of the most advanced pulsars in our galaxy. It is one of the most fascinating examples of how pulsars can create their surroundings with their powerful winds. This pulsar spins approximately 7 times per second and emits powerful jets of energy and particles that create a cloaked warbird-shaped structure. The "Jets" of this cosmic ship are moving at almost 9 million miles per hour as they hit a cloud of gas called RCW 89.

The area consists of several globules and dark dust clouds as well as Herbig Haro object HH 120. The Globules are estimated to be 1000 light years from here. A cometary globule is an interstellar cloud with comet-like morphology, consisting of compact, dusty opaque heads with long faintly luminous tails. Unlike dark nebulae or dark dust clouds, CG’s are isolated neutral globules surrounded by a hot ionized medium. Cometary Globules were only recently identified in 1976.

According to the GCVS variability classification scheme [7] the CoKu HP Tau/G2 is an Orion type variable (“irregular, eruptive variables connected with bright or dark diffuse nebulae or observed in the regions of these nebulae”) located at a distance of about 161 pc as measured by VLBA using the direct parallax method [8, 9], at which distance the edge of the image frame corresponds to 2.7 ly = 169 kAU. Manually annotated cropped view to The CoKu HP Tau/G2 and CoKu HP Tau/G3 are believed to form a gravitationally bound system according to [8, 9] and on top of that both V* HP Tau and CoKu HP Tau/G3 were confirmed to be tight binaries by themselves based on lunar occultation data analysis under [10, 11] and the orbital solution for HP Tau/G3 can be found in [12, 13]. Thus, the CoKu HP Tau/G2 plus CoKu HP Tau/G3 system appears to be a hierarchical triple star system [8, 9]. Furthermore, treating the V* HP Tau plus CoKu HP Tau/G2 plus CoKu HP Tau/G3 as a wide triple system (intentionally neglecting tightly coupled components of V* HP Tau and CoKu HP Tau/G3) [14, 15] gives masses for its components as 0.94, 2.49, 0.72 Solar masses correspondingly, with separation between CoKu HP Tau/G2 and V* HP Tau determined to be 3089 AU and separation between CoKu HP Tau/G2 and Coku HP Tau/G3 determined to be 1463 AU. The age of these three stars is estimated to be in the range of only 3-8 Myr, with CoKu HP Tau/G3 being the youngest and CoKu HP Tau/G2 - the oldest in the group [8, 9]. The reflection nebula surrounding the HP Tau group consists of multiple concentric fronts of which the brightness drops and average radial width - increases as they move away from the central CoKu HP Tau/G2 (V1025 Tau) star. The curvature diameter of the smallest curved front features visible in the core of the nebula is about 0.043 ly = 2735 AU based on the estimated distance to the star from above. Another set of non-concentric fronts exists here as well, some of which seemingly associated with V* HQ Tau star located 5 arc.min away from HP Tau/G2 in the lower right part of the image frame. Many of the fronts are with peculiar 120 deg bends and junction points. The entire set of fronts is embedded in a dark cloud showing hints of an even more peculiar spiral structure reaching out to the edge of the frame. Simple attempt to fit the most prominent curved fronts in the central part of the image with circular shells centered (or nearly centered) on the stars belonging to the HP Tau group and the nearby stars visible in the FOV is given below in Fig. S2. Interestingly enough, some of those fit rather well (each circle is provided with the indicator of a center). Further study is needed to attempt a 3D reconstruction of this region and its relation to the Taurus Molecular Cloud situated in the range of distances between 130 and 160 pc according to [16, 17], so the V1025 Tau is actually expected to sit behind most of the structures of that dark cloud. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1706022337327-WPG2IGNRKK5P90VG9Q9I/image-asset.jpeg Nebula - The Carina Nebula and “The Lost Relics” The Carina Nebula and “The Lost Relics” The Carina nebula is one of the best known and most prominent nebulae in the Southern Sky also known as The Carina Nebula , Eta Carina Nebula NGC 3372as well as Great Carina Nebula .

The central part of the image is taken by the LHA 115-N 78 HII complex [1] which is about 160 ly across (linear equivalent at a distance to the SMC) featuring many accompanying structures including a planetary nebula candidate [2], open star cluster IC 1624 [3, 4] caught in the crossing of several shock fronts (shown in a cropped image below at 100% of original resolution), complete with great many small scale structures visible in the inner volume of the “main bubble” of the complex. One of the most noticeable of those small structures is a “torii gate” structure highlighted by red markings on the cropped image below (shown at 200% scale to the original resolution) which is only about 10 arc.sec across, but still corresponding to an impressive 9.6 ly of linear scale (given the distance to the SMC). This particular area could be of interest to study with larger aperture systems. The list of peculiar objects in this frame is continued by a compact DEM S131 HII region [5] at the top side of the image shown in a cropped image below (at 150% scale to the original resolution) with IKT 25 X-ray binary [6] in the middle which is identified as a Type Ia SNR in [7]. A larger but fainter Q-shaped diffuse structure is visible in the mid-left side of the frame, a part of which is identified as DEM S132 HII region [8]. Many dark nebulae are visible across the frame, many of which are surveyed under [9, 10], showing well against the backdrop of the inner volume of the HII regions. A noteworthy set of nested radial shock fronts is also found in the lower right corner.

The dust clouds effectively block light from distant background stars in the Milky Way. But the striking complex of reflection nebulae cataloged as NGC 6726, 6727, and IC 4812 produce a characteristic blue color as light from the region's young hot stars is reflected by the cosmic dust. The dust also obscures from view stars still in the process of formation. At the left, smaller yellowish nebula NGC 6729 bends around young variable star R Coronae Australis. Just below it, glowing arcs and loops shocked by outflows from embedded newborn stars are identified as Herbig-Haro objects. On the sky this field of view spans about 1 degree.

This cloud overlays a rich field of background Milky Way stars. These background stars appear to be heavily "reddened" by the cloud's intervening dust. A large dark nebula extending throughout the region is cataloged Dobashi 12605,6. These areas of dense dust obscures background stars and other celestial objects. The bright blue central nebula shines from light reflected from the bright star designed HD 1706341. The blue color is a result of the surrounding dust reflecting the shorter wavelengths of light more efficiently than longer wavelengths. This is essentially the same phenomena that makes our Earthly sky appear blue. Standing out in contrast to VDB 123 just to the right of the blue vdB nebula is a red/orange bi-polar nebula known as the Serpens Reflection Nebula. (SNR)4 It is being illuminated by the relative low mass star designated Serpens/SVS 24. The nebula's outflow appears to be heavily influenced by embedded magnetic fields. This may have triggered the bi-polar shape of the nebula. Imaged in LRGB with our PlaneWave CDK 24 at Observatorio El Sauce, Chile.

The bulk of Coalsack nebula sits at a much closer distance of about 650 ly with the secondary dark clouds located as far as 10 kly in its corners [4, 5] but not where the RCW 71 is situated. Thus, RCW 71 gets most of the attenuation from that bulk of the Coalsack nebula and thus is easily detectable even on wide angle images of the area such as [6] as a bright red spot of about 2 arc. min in diameter. At the measured distance of 6.8 kly this angular diameter corresponds to the linear size of about 4 ly for the core (the HII region) of RCW 71. Earlier observations of this object by Midcourse Space Experiment (MSX) [7] revealed that it is surrounded by a ring of infrared emissions in the MSX A (8 mkm) spectral band [2, 3] for which the optical counterpart in Ha is revealed for the first time in this new image extending as far as 6 arc. min from the central star (HD 311999). Many additional details can be seen here in the core of the nebula such as two incomplete circles of dark nebulae filaments and what appears to be an ionization shock front about 1 arc.min away from the central star (above it in the specific orientation of the image). Another interesting feature revealed in the halo is what appears to be a thick dark filament stretching from the core of RCW 71 into the top right corner of the image which could be at least partially a denser part of Coalsack nebula overlapping with more distant structures. Unfortunately, the RCW 71 was just left out of the survey bands of Spitzer IRAC Equatorial Survey [8, 9] so further cross-referencing of the fine details of the optical counterpart of the halo in near-IR is difficult. However Herschel targeted this object over several observation sessions and produced details narrow FOV [10] and wide angle FOV [11] views of it in 100-160 mkm and 250-500 mkm spectral bands correspondingly that do confirm the presence of the diffuse halo around RCW 71 of up to 12 arc. min distance from the core of the nebula.

It is the brightest diffuse reflection nebula in a group of nebulae that includes NGC 2064, NGC 2067, and NGC 2071. It lies at an approximate distance of 1,600 light years from Earth. It has the designation NGC 2068 in the New General Catalogue. What is supersizing is how many other interesting objects are in this nebula. This patch of sky is absolutely gorgeous. It houses many Herbig-Haro (HH) objects are luminous regions surrounding newborn stars, formed when stellar winds or jets of gas spewing from these newborn stars form shock waves colliding with nearby gas and dust at high speeds. See the face hiding in the center of NGC 2068 (M78) McNeil’s Nebula is also in this frame, while it’s not impressive in this image. I was imaging this object in 2003 and noticed it when I heard of the discovery. Too bad I didn’t examine the images very well back then.

All its gaseous colors and structures: twisting, looping, bubbling, and exploding onto the screen. Nemours globular clusters and millions of stars are also visible. What a beautiful site it is. The Small Magellanic Cloud (SMC) is a dwarf galaxy near the Milky Way. Classified as a dwarf irregular galaxy, SMC contains several hundred million stars. It has a total mass of approximately 7 billion solar masses. At about 200,000 light-years away from us, the SMC is among the nearest intergalactic neighbors of the Milky Way and is one of the most distant objects visible to the naked eye. The SMC is visible from the entire Southern Hemisphere but can be fully glimpsed low above the southern horizon from latitudes south of about 15° north. The galaxy is located across both the constellations of Tucana and part of Hydrus, appearing as a faint hazy patch resembling a detached piece of the Milky Way. The SMC has an average apparent diameter of about 4.2° (8 times the Moon's) and thus covers an area of about 14 square degrees (70 times the Moon's). Since its surface brightness is very low, this deep-sky object is best seen on clear moonless nights and away from city lights. The SMC forms a pair with the Large Magellanic Cloud (LMC), which lies 20° to the east, and like the LMC, it is a member of the Local Group. It is currently a satellite of the Milky Way but is likely a former satellite of the LMC.

The bubble associated with this SNR is estimated to be only 2.4 arc.min in diameter (140 ly linear size given the distance to the SMC), but it is also superimposed by the 5 arc.min in size (290 ly linear size) elongated shell (possibly a side of a larger bubble) [4, 5] thus forming a complex cascade of loops with a rather fine structure. This object was a target of several recent studies including [6] using the observations performed with XMM-Newton and Australia Telescope Compact Array (ATCA). The alternative explanation of this “cascade” structure suggested by [4, 5] is as a single large SNR bubble of which the spot identified as SNR B0050−72.8 is just a most active region in X-ray and radio-continuum parts of the spectrum. There are many fainter diffuse structures visible in the FOV some of which may comprise the walls of that hypothetical larger SNR bubble as well as more compact nebular and HII regions.

While its angular diameter is of about 8 arc.min, since it is physically bound to the SMC the linear size of the region is of about 465 ly while the side of the image is of linear size of about 1 kly at that distance. Due to its apparently twisted shape we call it a “little spindle” here despite its impressive linear size. The nebula is comprised of at least 5 overlapping bubbles associated with supernova remnants [1-5] with one more supernova remnant candidate [6] also identified by the Simbad Database for which the bubble either already dissipated or obscured by the rest of the structures . The “roof” of the nebula complex located at the top of the “spindle” is composed of an elaborate collection of shock fronts for which the origin is not so easily traced. The image shows the unprecedented level of detail on this target,making that collection of the shock fronts an attractive target for imaging with large aperture instruments.

One of its most distinctive features, however, is the dark, starry gap called a “superbubble,” visible in this Hubble Space Telescope image in the upper central region. The hole is about 250 light-years wide and its presence is still something of a mystery. Stellar winds expelled by massive stars in the bubble's interior may have driven away the gas, but this is inconsistent with measured wind velocities in the bubble. Another possibility, since the nebula is filled with massive stars that would expire in titanic explosions, is that the expanding shells of old supernovae sculpted the cosmic cavern. Astronomers have found one supernova remnant in the vicinity of the superbubble and identified an approximately 5 million year difference in age between stars within and at the rim of the superbubble, indicating multiple, chain-reaction star-forming events. The deep blue area at about 5 o’clock around the superbubble is one of the hottest regions of the nebula and the area of the most intense star formation. N44 is an emission nebula, which means its gas has been energized, or ionized, by the radiation of nearby stars. As the ionized gas begins to cool from its higher-energy state to a lower-energy state, it emits energy in the form of light, causing the nebula to glow. Located in the Large Magellanic Cloud, N44 spans about 1,000 light-years and is about 170,000 light-years away from Earth. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1692725387216-7TRK621O3IKIMJ647I92/VDB4-Webcrop.jpg Nebula - VDB 4 - NGC 225 NGC 225 is an open cluster in the constellation Cassiopeia. One of it's stars, the variable star V594 Cas, illuminates the blue reflection nebula van den Bergh (vdB) 4, which also cataloged as LBN 604. It seems, that vdB 4 is a remnant from the cloud that formed the cluster. The name Sail Boat Cluster (NGC 225) was given to the open cluster located in the constellation of Cassiopeia by Rod Pommier, referring to the visual appearance of the object. There are a lot of gas and dust clouds around the cluster, part of which is being lit by the nearby cluster members, making it shine in blue. The cluster was discovered by Caroline Herschel in 1783, who entered the object as #11 on her private list of deep-sky objects. A few months later, in 1784, as a mistake, she discovered it again, and listed it again as object #15 on her list. The cluster visible in the constellation of Cassiopeia is a bit more than 2000 light-years away from us, by that distance the cluster is considered one of the nearby clusters to us. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1692237946568-ZX4TK11182PAQAAAF7Z9/CocoonNebula+Final.jpg Nebula - Cocoon Nebula, IC 5146 inside the Cocoon Nebula is a newly developing cluster of stars. Cataloged as IC 5146, the beautiful nebula is nearly 15 light-years wide, located some 4,000 light years away toward the northern constellation Cygnus. Like other star forming regions, it stands out in red, glowing, hydrogen gas excited by young, hot stars and blue, dust-reflected starlight at the edge of an otherwise invisible molecular cloud. In fact, the bright star near the center of this nebula is likely only a few hundred thousand years old, powering the nebular glow as it clears out a cavity in the molecular cloud's star forming dust and gas. This exceptionally deep color view of the Cocoon Nebula traces tantalizing features within and surrounding the dusty stellar nursery.     https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1691181081567-2I10JY4PP6A9ZOW7EVNO/image-asset.jpeg Nebula - RCW 103 Supernova Remnant RCW 103 Supernova Remnant The RCW catalogue was prepared by Alex Rodgers, Colin Campbell, and John Whiteoak, working at Mount Stromlo observatory under the direction of Dutch-American astronomer Bart Bok. The RCW catalog is largely an expansion of Colin Gum's 1955 catalog. RCW 103 is a 2000-year-old supernova remnant, pictured here using narrowband filters with its beautiful wispy tangled web of emissions. The star that caused this explosion was a star 8-10 times the size of our own sun and is now a neutron star not visible in visible wavelengths in this image. Recent Chandra X-Ray Observatory observations show a blue dot at the center which is interpreted as the neutron star formed in the explosion. This neutron star is quite special as it spins quite slow in caparison to most.

It's on the border of the constellations of Cepheus and Lacerta. It's estimated to be about 10,000 light years away. The star field is very rich, so the nebula is almost lost amidst all the stars. It’s home to Wolf-Rayet star WR153ab. These massive stars are nearing their transition to supernova or black hole. In the OIII wavelength there appears to be a river of blue gasses running up through the nebula.

The surrounding nebula IC 405 is named the Flaming Star Nebula and the region seems to harbor smoke, but there is no fire. Fire, typically defined as the rapid molecular acquisition of oxygen, happens only when sufficient oxygen is present and is not important in such high-energy, low-oxygen environments. The material that appears as smoke is mostly interstellar hydrogen but does contain smoke-like dark filaments of carbon-rich dust grains. The bright star AE Aurigae, visible near the nebula center, is so hot it is blue, emitting light so energetic it knocks electrons away from atoms in the surrounding gas. When an atom recaptures an electron, light is emitted creating the surrounding emission nebula.

The bluish reflection nebula with the two embedded double stars is IC 4601 (vdB 102,vdB 103), the yellowish reflection nebula is vdB 101. The two reflection nebulae appear so different due to the temperature differences of the illuminating stars. These types of nebulae are called “reflection,” because they reflect the light of nearby stars. IC 4601 is illuminated by the intense radiation of the stars present in its vicinity, among which the most brilliant star HD 147010, and the two stars of a binary system known as HD 147013, which are all blue giants. The dust of IC 4601 contains the heavy elements that planets are made of and plays a major role in the creation of new stars. There probably are baby stars wrapped in these blankets of dust.

Seen at the center of the cosmic cloud, the star is a mere 3 to 4 million years old. In another three to four million years the massive star will end its life in a supernova explosion. Spanning around 4 light-years, the nebula itself has a bipolar symmetry. That makes it similar in appearance to more common and familiar planetary nebulae - the gaseous shrouds surrounding dying sun-like stars. Also like many planetary nebulae, NGC 6164 has been found to have an extensive, faint halo, revealed in this deep telescopic image of the region. Expanding into the surrounding interstellar medium, the material in the halo is likely from an earlier active phase of the O star. The gorgeous skyscape is a composite of extensive narrow-band image data, highlighting glowing atomic hydrogen gas in red and oxygen in blue hues, with broad-band data for the surrounding starfield. NGC 6164 is 4,200 light-years away in the right-angled southern constellation of Norma.

Churning and mixing interstellar clouds of gas and dust, stars -- most notably those upwards of tens of times the mass of our Sun -- leave their mark on the compositions and locations of future generations of stars. Dramatic evidence of this is illustrated in our neighboring galaxy, the Large Magellanic Cloud (LMC), by the featured nebula, Henize 70 (also known as N70 and DEM301). Henize 70 is actually a luminous superbubble of interstellar gas about 300 light-years in diameter, blown by winds from hot, massive stars and supernova explosions, with its interior filled with tenuous hot and expanding gas. Because superbubbles can expand through an entire galaxy, they offer humanity a chance to explore the connection between the lifecycles of stars and the evolution of galaxies. An Amazing Explorer’s Legacy – the Henize Objects. In a recent project my astrophotography group, using a 24” Planewave telescope high in the Andes in Chile, targeted the object known as Henize 70. The image below is the result of this effort. From this I became curious about the history of the Henize objects. The astronomer Karl Henize spent years studying the Large Magellanic Cloud (LMC), the dwarf galaxy nearest us visible only from the southern hemisphere. He created a catalog of interesting objects in it during his career as Professor of Astronomy at Northwestern University. In 1967 he gave up his full professorship to became an Apollo astronaut and was actually slated to fly on Apollo 20 or 21 had the NASA project not been discontinued. In 1985 he finally did go into space on the Space Shuttle Challenger with the SpaceLab2 experiment. Henize had a lifelong interest in the LMC and created the catalog of interesting objects now bearing his name. Exploration was his game, and ultimately how he went out – at age 70 in 1994 he died climbing Mount Everest, where his body was buried at 22,000 ft.

In fact, the Crab is now known to be a supernova remnant, debris from the death explosion of a massive star, witnessed by astronomers in the year 1054. These sharp, ground-based telescopic views, combines broadband color data with narrowband data that tracks emission from ionized sulfur, hydrogen, and oxygen atoms to explore the tangled filaments within the still expanding cloud. One of the most exotic objects known to modern astronomers, the Crab Pulsar, a neutron star spinning 30 times a second, is visible as a bright spot near the nebula's center. Like a cosmic dynamo, this collapsed remnant of the stellar core powers the Crab's emission across the electromagnetic spectrum. Spanning about 12 light-years, the Crab Nebula is a mere 6,500 light-years away in the constellation Taurus.

Such stars exist, and some are known as Wolf Rayet (WR) stars, named after French astronomers Charles Wolf and Georges Rayet. The central star in this image is WR 40 which is located toward the constellation of Carina. Stars like WR 40 live fast and die young in comparison with the Sun. They quickly exhaust their core hydrogen supply, move on to fusing heavier core elements, and expand while ejecting their outer layers via high stellar winds. In this case, the central star WR 40 ejects the atmosphere at a speed of nearly 100 kilometers per second, and these outer layers have become the expanding oval-shaped nebula RCW 58. This just looks like you can hear it sizzling! RCW58, an E type nebula, is a Wolf Rayet Bubble formed by the ejecta from WR 40, the central star in the image. These three-dimensional bubbles appear as a ring in two dimensions, as seen in this image and represent the stellar ejecta contained in a windblown bubble. The are several similar WR ring nebulae are known including: MI-67, RCW104, RCW78, NGC3199, NGC6888. H alpha and OIII emissions from eight of the most well defined Wolf Rayet ring nebulae in the Galaxy reveal that in many cases the outermost edge of the OIII emission leads the H alpha emission. This suggests that these offsets, when present, are due to the shock from the Wolf Rayet bubble expanding into the circumstellar envelope.

It is classified as an emission nebula and as an H II region. The Lagoon Nebula was discovered by Giovanni Hodierna before 1654[4] and is one of only two star-forming nebulae faintly visible to the eye from mid-northern latitudes. Seen with binoculars, it appears as a distinct oval cloudlike patch with a definite core. Within the nebula is the open cluster NGC 6530.[5] Lagoon Nebula in HaRGB The Lagoon Nebula is estimated to be between 4,000-6,000 light-years away from the Earth. In the sky of Earth, it spans 90' by 40', which translates to an actual dimension of 110 by 50 light years. Like many nebulas, it appears pink in time-exposure color photos but is gray to the eye peering through binoculars or a telescope, human vision having poor color sensitivity at low light levels. The nebula contains a number of Bok globules (dark, collapsing clouds of protostellar material), the most prominent of which have been catalogued by E. E. Barnard as B88, B89 and B296. It also includes a funnel-like or tornado-like structure caused by a hot O-type star that emanates ultraviolet light, heating and ionizing gases on the surface of the nebula. The Lagoon Nebula also contains at its centre a structure known as the Hourglass Nebula (so named by John Herschel), which should not be confused with the better known Engraved Hourglass Nebula in the constellation of Musca. In 2006 the first four Herbig–Haro objects were detected within the Hourglass, also including HH 870. This provides the first direct evidence of active star formation by accretion within it.[2] https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1628538962306-10GYIM4FJ0OZOR7C338C/NGC6357HansonT.jpg Nebula - NGC 6357 War and Peace Nebula - Lobster Nebula NGC 6357 War and Peace Nebula - Lobster Nebula Taken from SWOS in El Sauce, Chile 24” PlaneWave CDK Explanation from APOD: Why is the Lobster Nebula forming some of the most massive stars known? No one is yet sure. Cataloged as NGC 6357, the Lobster Nebula houses the open star cluster Pismis 24 near its center -- a home to unusually bright and massive stars. The overall blue glow near the inner star forming region results from the emission of ionized hydrogen gas. The surrounding nebula, featured here, holds a complex tapestry of gas, dark dust, stars still forming, and newly born stars. The intricate patterns are caused by complex interactions between interstellar winds, radiation pressures, magnetic fields, and gravity. NGC 6357 spans about 400 light years and lies about 8,000 light years away toward the constellation of the Scorpion. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1628538783824-Y82LZ0KT7JOPO45AOMUV/CatsPawNeb-LRGBHAO3S2-80T.jpg Nebula - NGC 6334 Explanation via APOD: Nebulas are perhaps as famous for being identified with familiar shapes as perhaps cats are for getting into trouble. Still, no known cat could have created the vast Cat's Paw Nebula visible in Scorpius. At 5,500 light years distant, Cat's Paw is an emission nebula with a red color that originates from an abundance of ionized hydrogen atoms. Alternatively known as the Bear Claw Nebula or NGC 6334, stars nearly ten times the mass of our Sun have been born there in only the past few million years. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1619442709188-8E2WVKMOOCF5Q0POQEAH/NGC6726V-3.jpg Nebula - NGC 6726 Cosmic dust clouds sprawl across a rich field of stars in this sweeping telescopic vista near the northern boundary of Corona Australis, the Southern Crown. Less than 500 light-years away the dust clouds effectively block light from more distant background stars in the Milky Way. The entire frame spans about 2 degrees or over 15 light-years at the clouds' estimated distance. Near center is a group of lovely reflection nebulae cataloged as NGC 6726, 6727, 6729, and IC 4812. A characteristic blue color is produced as light from hot stars is reflected by the cosmic dust. The dust also obscures from view stars in the region still in the process of formation. Smaller yellowish nebula NGC 6729 surrounds young variable star R Coronae Australis. Below it are arcs and loops identified as Herbig Haro objects associated with energetic newborn stars. Magnificent globular star cluster NGC 6723 is at the right. Though NGC 6723 appears to be part of the group, its ancient stars actually lie nearly 30,000 light-years away, far beyond the young stars of the Corona Australis dust clouds. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1618275817092-U58ZUYBIFCYR59VVMU9M/ConeThumb.jpg Nebula - The Cone Nebula Explanation: Strange shapes and textures can be found in neighborhood of the Cone Nebula. The unusual shapes originate from fine interstellar dust reacting in complex ways with the energetic light and hot gas being expelled by the young stars. The brightest star on the right of the above picture is S Mon, while the region just above it has been nicknamed the Fox Fur Nebula for its color and structure. The blue glow directly surrounding S Mon results from reflection, where neighboring dust reflects light from the bright star. The orange glow that encompasses the whole region results not only from dust reflection but also emission from hydrogen gas ionized by starlight. S Mon is part of a young open cluster of stars named NGC 2264, located about 2500 light years away toward the constellation of Monoceros. The origin of the mysterious geometric Cone Nebula, visible on the far left, remains a mystery. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1618237267775-3LAKZK0J8RZHOY61OYQR/NGC+3324Thumb.jpg Nebula - NGC 3324- Gabriela Mistral Nebula NGC 3324- Gabriela Mistral Nebula Description via APOD. Explanation: This bright cosmic cloud was sculpted by stellar winds and radiation from the hot young stars of open cluster NGC 3324. With dust clouds in silhouette against its glowing atomic gas, the pocket-shaped star-forming region actually spans about 35 light-years. It lies some 7,500 light-years away toward the nebula rich southern constellation Carina. A composite of narrowband image data, the telescopic view captures the characteristic emission from ionized sulfur, hydrogen, and oxygen atoms mapped to red, green, and blue hues in the popular Hubble Palette. For some, the celestial landscape of bright ridges of emission bordered by cool, obscuring dust along the right side create a recognizable face in profile. The region's popular name is the Gabriela Mistral Nebula for the Nobel Prize winning Chilean poet.

It is estimated to be only 300,000 years old. Stars, the Sun included, were born within clouds of dusty gas such as the Trifid Nebula. This young nebula contains enough material to make many thousands of suns. Within it a number of young hot stars have already formed. The Trifid Nebula, meaning ‘divided into three lobes’, is an unusual combination of a red emission nebula with a young open star cluster near its center, surrounded by a blue reflection nebula which is particularly conspicuous to the northern end, and a dark absorption nebula (the apparent ‘gaps’ within the emission nebula that cause the trifid appearance; these are also designated Barnard 85). The hydrogen molecules in the emission nebula at the Trifid’s core is heated by hundreds of brilliant young stars causing it to emit red light. The dense part of the nebula is a stellar nursery full of embryonic stars (NASA’s Spitzer Space Telescope discovered 30 embryonic stars and 120 newborn stars, not seen in visible light images). The star cluster, known as C 1759-230, may well be the youngest star cluster in our Milky Way galaxy. The blue color of the reflection nebula comes from cosmic dust grains which preferentially reflect the blue component of starlight as it scatters light from bright new stars that were formed nearby. The largest and hottest of these stars shines most brightly in the hot, blue portion of the visible spectrum. In some parts of the nebula there are so many dust grains that they hide the glowing gas, producing the dark absorption lanes, which were created in the atmospheres of cool giant stars and in the debris from supernovae explosions. Within these dark lanes, the remains of previous star births and deaths continue to collapse under gravity’s unrelenting attraction. The rising density, pressure and temperature inside these dark blobs will eventually trigger the formation of new stars. Close-up images show a finger-like stalk in the emission nebula that points from the head of a very dense cloud directly toward the star that powers the Trifid nebula, which is actually a triple system of extremely hot stars. This stalk is a prominent example of evaporating gaseous globules, or ‘EGGs’. The stalk has survived because its tip is a knot of gas that is dense enough to resist being eaten away by the powerful radiation from the star.

The nebula's linear appearance triggered its popular name. It resides about 815 light-years (250 parsecs) away from the Solar System. It is thought to be formed from part of the shock wave of the larger Vela Supernova Remnant. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1600736618618-5MZH260ONXLF34SRVT3B/N44T.jpg Nebula - n44 N44 is an emission nebula with superbubble structure located in the Large Magellanic Cloud, a satellite galaxy of the Milky Way in the constellation Dorado.[3][4][5] Originally catalogued in Karl Henize's "Catalogue of H-alpha emission stars and nebulae in the Magellanic Clouds" of 1956, it is approximately 1,000 light-years wide and 160,000-170,000 light-years distant.[6][7][1] N44 has a smaller bubble structure inside known as N44F. The superbubble structure of N44 itself is shaped by the radiation pressure of a 40-star group located near its center; the stars are blue-white, very luminous, and incredibly powerful.[6][1] N44F has been shaped in a similar manner; it has a hot, massive central star with an unusually powerful stellar wind that moves at 7 million kilometers per hour. This is because it loses material at 100 million times the rate of the Sun, or approximately 1,000,000,000,000,000 tons per year. However, varying density in the N44 nebula has caused the formation of several dust pillars that may conceal star formation.[6] This variable density is likely caused by previous supernovae in the vicinity of N44; many of the stars that have shaped it will eventually also end as supernovae. The past effects of supernovae are also confirmed by the fact that N44 emits x-rays.[4][8] N44 is classified as an emission nebula because it contains large regions of ionized hydrogen. However, the three strongest emission lines in the nebula are singly ionized oxygen atoms, which emit at an ultraviolet wavelength of 372.7 nm, doubly-ionized oxygen atoms, which emit at a blue-green wavelength of 500.7 nm, and neutral hydrogen atoms, which emit the hydrogen-alpha line at a red wavelength of 656.2 nm.[1][9] References https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1600733913175-3CX5PO0RHLKUXT2Z091L/IC1248-3T.jpg Nebula - IC 1284 IC 1284 IC 1284 (bottom left) and NGC 6590 (lower-mid right) There is hardly any background sky in this very dusty part of the southern Milky Way.

It was discovered by Gottfried Kirch in 1681. Charles Messier included it in his catalogue of diffuse objects in 1764. Its popular name derives from the brighter stars forming a triangle which could resemble a flying flock of ducks (or, from other angles, one swimming duck). The cluster is located just to the east of the Scutum Star Cloud midpoint. The Wild Duck Cluster is one of the richest and most compact of the known open clusters. It is one of the most massive open clusters known, and it has been extensively studied. Its age has been estimated to about 316 million years.

These three dimensional bubbles appear as a ring in two dimensions, as seen in this image and represent the stellar ejecta contained in a wind blown bubble. The are several similar WR ring nebulae are known including: MI-67, RCW104, RCW78, NGC3199, NGC6888. H alpha and OIII emissions from eight of the most well defined Wolf Rayet ring nebulae in the Galaxy reveal that in many cases the outermost edge of the OIII emission leads the H alpha emission. This suggests that these offsets, when present, are due to the shock from the Wolf Rayet bubble expanding into the circumstellar envelope.

The transient occurred in the direction of Alpha Centauri, between the constellations Circinus and Centaurus, centered at RA 14h 43m Dec −62° 30′, in Circinus. This "guest star" was observed by Chinese astronomers in the Book of Later Han ,and might have been recorded in Roman literature. It remained visible in the night sky for eight months. This is believed to be the first supernova for which records exist. The gaseous shell RCW 86 is probably the supernova remnant of this event and has a relatively large angular size of roughly 45 arc minutes (larger than the apparent size of the full moon, which varies from 29 to 34 arc minutes). The distance to RCW 86 is estimated to be 9,100 light-years). Recent X-ray studies show a good match for the expected age.

In this classic celestial still life composed with a cosmic brush, dusty nebula NGC 2170, also known as the Angel Nebula, shines near the image center. Reflecting the light of nearby hot stars, NGC 2170 is joined by other bluish reflection nebulae, a red emission region, many dark absorption nebulae, and a backdrop of colorful stars. Like the common household items that still life painters often choose for their subjects, the clouds of gas, dust, and hot stars featured here are also commonly found in this setting -- a massive, star-forming molecular cloud in the constellation of the Unicorn (Monoceros). The giant molecular cloud, Mon R2, is impressively close, estimated to be only 2,400 light-years or so away. At that distance, this canvas would be over 60 light-years across.

It is one of the most active star formation regions in the nearby Universe. It is one of the largest and most spectacular star-forming regions within the Large Magellanic Cloud (LMC), the largest satellite galaxy of our Milky Way. In fact, it is the second largest, only surpassed in the size and activity by the Tarantula nebula (or 30 Doradus), located at the opposite side of the LMC. The dramatic and colorful features visible in the nebula are the telltale signs of star formation. A leading hypothesis for the formation of NGC 1760 is that several successive generations of stars, each of which formed further away from the center of the nebula than the last, have created shells of gas and dust. These shells were blown away from the newborn stars in the turmoil of their energetic birth and early life, creating the ring- and bean-like shapes so prominent in this image. In NGC 1760 altogether, three generations of stars can be found. ‘Grandmother’ stars that have carved a large superbubble, leading to the birth of the cluster of massive bright blue-white ‘mother’ stars (NGC 1761) in the center. These in turn gives birth to new star ‘babies’ inside the dark globules. NGC 1761 (also designated LH9) is composed of about 50 massive hot young stars that emit intense ultraviolet radiation that has eroded a large hole in their surroundings. These stars are among the most massive stars known anywhere in the Universe. The bright region just above center is N11B, another explosive domain where stars are being formed even today. Although the Large Magellanic Cloud is much smaller than our own Milky Way, it is an active star-forming galaxy. Studying these stellar nurseries helps astronomers understand a lot more about how stars are born and their ultimate development and lifespan.

The nebula is approximately 8,500 light-years (2,600 pc) from Earth. The nebula has within its boundaries the large Carina OB1 association and several related open clusters, including numerous O-type stars and several Wolf–Rayet stars. Carina OB1 encompasses the star clusters Trumpler 14 and Trumpler 16. Trumpler 14 is one of the youngest known star clusters at half a million years old. Trumpler 16 is the home of WR 25, currently the most luminous star known in our Milky Way galaxy, together with the less luminous but more massive and famous Eta Carinae star system and the O2 supergiant HD 93129A. Trumpler 15, Collinder 228, Collinder 232, NGC 3324, and NGC 3293 are also considered members of the association. NGC 3293 is the oldest and furthest from Trumpler 14, indicating sequential and ongoing star formation. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1580913555258-YHFHM2MQH6B2V7COCMWM/NGC-2020-180-80small.jpg Nebula - NGC 2020 Two unlikely nebulae located side-by-side. The pinkish nebula on the middle bottom, known as NGC 2014, is an ionized gas cloud comprised almost entirely of hydrogen. A cluster of stars are responsible for the characteristic glow accompanying the ionization. When the stellar winds pierced through the galaxy, hydrogen atoms were stripped of their electrons when they came in contact with ultraviolet radiation streaming from young, energetic stars . The clouds of gas were then reborn when the hydrogen and their electrons recombined. Its blueish partner (pictured on the bottom right) is NGC 2020. Its bubble-like cavity was naturally carved out as gaseous material was carried away by stellar winds.In contrast to NGC 2014, the bluish hue seen here is the work of one single, massive, unstable star called a Wolf-Rayet star. Instead of acting as an agent for the ionization of hydrogen, this star is responsible for ionizing surrounding oxygen atoms.

LDN 43 has received lots of attention from professional astronomers seeking to understand the mysteries of star formation. It is one of the closest star forming regions with a distance of slightly more than 500 light years. The area around it suffers from a high degree of dust extinction. This is best illustrated by the interstellar reddening of the majority of the stars in this image as well a few distant background galaxies. Any light travelling from these sources passes through this veil of dust, which absorbs the blue light making everything appear more red than it actually is. Interstellar dust extinction is prevalent in many parts of the Milky Way and many galaxies would shine more brightly if not for this intervening dust. Observations with radio telescopes have uncovered multiple molecular outflows in the vicinity of RNO 91, which are an indicator of the energetic activity of nascent YSO's. The outflows have carved out a cavity in the surrounding dark cloud, which is illuminated by the source of RNO 91, a type of YSO known as a T Tauri star. This is known to be encircled by a protoplanetary disk, which is a solar system in the making. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1572800225347-TCRHGK63ILHMXHLKJD5W/Tulip-WebT.jpg Nebula - Tulip Nebula Explanation: Framing a bright emission region, this telescopic view looks out along the plane of our Milky Way Galaxy toward the nebula rich constellation Cygnus the Swan.

Collapsing from vast cosmic clouds, their nuclear furnaces ignite and create heavy elements in their cores. After a few million years, the enriched material is blasted back into interstellar space where star formation can begin anew. The expanding debris cloud known as Cassiopeia A is an example of this final phase of the stellar life cycle. Light from the explosion which created this supernova remnant would have been first seen in planet Earth's sky about 350 years ago, although it took that light about 11,000 years to reach us. This false-color image, composed of X-ray and optical image data from the Chandra X-ray Observatory and Hubble Space Telescope, shows the still hot filaments and knots in the remnant. It spans about 30 light-years at the estimated distance of Cassiopeia A. High-energy X-ray emission from specific elements has been color coded, silicon in red, sulfur in yellow, calcium in green and iron in purple, to help astronomers explore the recycling of our galaxy's star stuff. Still expanding, the outer blast wave is seen in blue hues. The bright speck near the center is a neutron star, the incredibly dense, collapsed remains of the massive stellar core. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1554159474084-PC0NM2W0JM6Q8QYD9ABG/NGC+104+LRBB70smallAPOD.jpg Nebula - 47 Tucanae or NGC 104 47 Tucanae or NGC 104 47 Tucanae is the second brightest globular cluster after Omega Centauri, and telescopically reveals about ten thousand stars, many appearing within a small dense central core.

William Herschel included his sister's discovery in his catalog, and labeled it H VIII.77. It is also known as 142 in the 1959 Sharpless catalog (Sh2-142). This reasonably large nebula is located in Cepheus. It is extremely difficult to observe visually, usually requiring very dark skies and an O-III filter. Located 7200 light years away, the Wizard nebula, surrounds developing open star cluster NGC 7380. Visually, the interplay of stars, gas, and dust has created a shape that appears to some like a fictional medieval sorcerer. The active star forming region spans about 100 light years, making it appear larger than the angular extent of the Moon. The Wizard Nebula can be located with a small telescope toward the constellation of the King of Aethiopia (Cepheus). Although the nebula may last only a few million years, some of the stars being formed may outlive our Sun.

Cataloged as Sh2-239 and LDN 1551, the region lies near the southern end of the Taurus molecular cloud complex some 450 light-years distant. Stretching for nearly 3 light-years, the canvas abounds with signs of embedded young stellar objects driving dynamic outflows into the surrounding medium. Included near the center of the frame, a compact, tell-tale red jet of shocked hydrogen gas is near the position of infrared source IRS5, known to be a system of protostars surrounded by dust disks. Just below it are the broader, brighter wings of HH 102, one of the region's many Herbig-Haro objects, nebulosity's associated with newly born stars. Estimates indicate that the star forming LDN 1551 region contains a total amount of material equivalent to about 50 times the mass of the Sun.

Otherwise catalogued as NGC 2261 by the astronomer John Louis Emil Dreyer in 1888 in his iconic New General Catalogue, this nebula was discovered in 1783 by William Herschel. It is also famous for the being the first deep sky object to have been photographed with the Hale Telescope at the Palomar Observatory in 1949 by none other than Edwin Hubble. The popular name of this nebula arises from it being studied by Edwin Hubble in 1916 who noticed it changed in brightness. It is now known that its dramatic and quite quick changes in brightness and appearance are the result of opaque clouds of dust situated between the star and the nebula. The appearance of NGC 2261 has been observed to change on timescales of a few months if not a few days! The reddish nebulosity visible to the north of NGC 2261 is an example of a Herbig Haro object, a type of jet ejected by a young star that glows by the energy generated by the gas colliding with its surrounding space. They were originally independently discovered by the astronomers George Herbig and Guillermo Haro. This Herbig Haro object is catalogued as HH 39 and more than a thousand are currently known. An analysis of the proper motion of the knots in HH 39 show that it is moving away from R Monocerotis and NGC 2261." LRGBHa 300,180,180,180,450 Taken with a PlaneWave 24" CDK from Animas New Mexico. Thank you, Mark https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1544625807872-I7RU5OUV6WELHPMS60PE/IC348+Web-2apod.jpg Nebula - IC 348 - IC 1985 IC 348 (also known as IC 1985) is a 2 million year old open star cluster surrounded by a reflection nebula of about 15 light-years across, located some 1028 light-years away from Earth in the northern constellation of Perseus, while it is receding from us at 14 kilometers per second. It is embedded in the star-forming region called the Perseus molecular cloud. The light from the roughly 400 stars in the cluster is scattered by clouds of dust in the star-forming region, producing the reflection nebula. The cluster’s brightest members are hot, bright bluish Main Sequence stars, but some stars are still in the process of formation, so star formation is an ongoing process in the region. The most massive stars in the cluster are the stars of the binary star system called BD+31°643. About half of the stars in the cluster have a circumstellar disk, of which 60% are primordial disks, where planets could be forming. Studies of circumstellar disks in clusters of various ages are expected to yield a better understanding of the dynamics of planet formation. Inside this extremely young cluster are also about thirty brown dwarfs discovered, with masses as low as 15 to 80 times that of Jupiter, as well as three brown dwarfs with estimated masses of less than 10 times that of Jupiter. Brown dwarfs lose heat as they age, so they are more readily discovered while they are still young. Current models estimate that their surfaces are approximately 900-1000 degrees Kelvin (about 600-700 degrees Celsius). That’s extremely cool for objects that have just formed, which implies that they have the lowest masses of any of this type of object that we’ve seen to date. The discovery of the dwarfs in IC 348 has allowed astronomers to set new limits on the lowest mass objects. Recently, astronomers discovered an unusual variable object inside IC 348 that appears to be a close binary pair of protostars, named LRLL 54361 (L54361 for short). This bright object emits flashes of light every 25.34 days. These two protostars drag material inwards from a surrounding disk of gas and dust. The light flashes are probably due to this material suddenly being dumped onto the growing stars as they near one another in their orbits, unleashing a blast of radiation. This is only the third time this phenomenon has been observed, and it is the most powerful such beacon seen to date. It is also the first to be seen associated with a light echo. Flashing double star systems like this one are rare, because close binaries account for only a few percent of our galaxy’s stellar population. Moreover, the pulsing light is likely to be a brief phenomenon in the early life of a star. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1541627404075-AOHHAXRN3OKCAPQ59V1L/CTB1-Apodsmall2.jpg Nebula - CTB1-Supernova Remnant Spanning an area of 35 arcminutes on the sky towards the constellation of Cassiopeia, this enigmatic loop of ionized nebulosity is a supernova remnant catalogued as CTB 1. This name denotes it as a radio source compiled in the Caltech Observatory list B catalogue of 110 radio sources discovered in a radio survey in 1960. A few other CTB sources also correspond with a supernova remnant such as CTB 80. The radio source CTB 1 was suspected to be a supernova remnant in 1960 and confirmed as a supernova remnant in 1971. Optical emission associated with it was discovered by Sidney van den Bergh in 1973. The optical structure consists of a roughly circular shell with a breakout rupture towards the north, which also coincides with a break in the radio shell at this location. This is likely to be the result of the supernova remnant's interaction with a nearby cavity of neutral hydrogen gas. The Ha shell is composed of multiple interlocking limb brightened filaments with faint emission also extending beyond the main shell towards the south. The OIII structure consists of a series of filaments forming a curved arc towards one side. Close inspection also reveals a small dark globule silhouetted against the southern part. CTB 1 belongs to the morphological class of mixed-morphology supernova remnants, which consist of a radio shell with central x-ray emission. Other prominent examples of this class include IC 443 and W28. At a distance of 10,000 light years, the diameter of CTB 1 is 100 light years. The expansion of the shell in a highly dynamic environment suggests that the progenitor star that exploded to form the supernova remnant might have been a B or O-type supergiant star. The age of CTB 1 has many estimates but the most commonly accepted one is 10,000 years. Interestingly this object has been considered erroneously as a planetary nebula and is catalogued as Abell 85 in George Abell's second version of the Abell planetary nebula catalogue published in 1966 and was also included in the first version published in 1955. It is also wrongly catalogued as a HII region in Beverley Lynd's amusingly named 1965 catalogue of bright nebulae as LBN 576. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1542318641042-9FKP89BGM154DWWS2ZTJ/NGC654Websmall.jpg Nebula - NGC 654 &amp; The Dark Serpent Cassiopeia's Dark Serpent Image Credit & Copyright: Mark Hanson Description by Mark Hanson NGC 654 is a brilliant colorful open cluster in the constellation Cassiopeia. It was discovered by William Herschel in 1787. Here is a great paper " from 1960 "Yerkes Observatory" not far from my home here in Madison, Wi. This deep image shows many more features of this area. The dark serpent shaped area seemingly getting ready to strike the open cluster NGC 654 are "Lynds Dark Nebula" or LDN objects. These were objects cataloged by Beverly T Lynds in 1962 called "Catalogue of Dark Nebula". Here we have three LDN objects 1332,1334,1337. Also, TGU H855 P2 another dark nebula. Next to NGC 654 we have VDB 6 a faint blue reflection nebula. VDB objects are 158 reflection nebulae cataloged by astronomer Sidney Van Den Bergh. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1542320938066-W8NK0TUHH3OPZBI0UA4D/IC+8171Apod2Final3Small.jpg Nebula - IC 1871 and SFO12 deep within the Soul Nebula "IC 1871 and SFO11 deep within the Soul Nebula" "Zooming in on the northeastern part of the Soul Nebula, this image shows a few groups of bright rimmed globules that are collectively catalogued as IC 1871 (right) and SFO 12 (left). Their gaseous forms are sculpted by the UV radiation and stellar winds from many hot young stars in the star cluster associated with the Soul Nebula. The term "bright rimmed" arises from the side of the globules that are facing the ionzing source exhibiting bright rims as a result of the gas and dust becoming more compressed and denser and therefore brighter than the surrounding material. In the case of IC 1871 and SFO 12, they point towards the cluster situated West of them (not visible in image).

The aptly named Pillars of Creation, featured in this stunning Hubble image, are part of an active star-forming region within the nebula and hide newborn stars in their wispy columns. Although this is not Hubble’s first image of this iconic feature of the Eagle Nebula, it is the most detailed. The blue colors in the image represent oxygen, red is sulfur, and green represents both nitrogen and hydrogen. The pillars are bathed in the scorching ultraviolet light from a cluster of young stars located just outside the frame. The winds from these stars are slowly eroding the towers of gas and dust. Stretching roughly 4 to 5 light-years, the Pillars of Creation are a fascinating but relatively small feature of the entire Eagle Nebula, which spans 70 by 55 light-years. The nebula, discovered in 1745 by the Swiss astronomer Jean-Philippe Loys de Chéseaux, is located 7,000 light-years from Earth in the constellation Serpens. With an apparent magnitude of 6, the Eagle Nebula can be spotted through a small telescope and is best viewed during July. A large telescope and optimal viewing conditions are necessary to resolve the Pillars of Creation. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1522852250081-B2IY3D3I7WH3G17VAT48/SH2-278APODsmall.jpg Nebula - SH2-278 From SWO SH2-278, Sharpless 278     "Billowing crimson waves of hydrogen gas cascade in an ocean of tranquility in this uncommon view of the rarely photographed emission nebula Sh2-278. Adding a ghostly presence to the proceedings are clouds of blue dust glowing by reflected starlight.   The most apparent component of this cosmic vista is the bright rimmed dark nebula LDN 1634 to the left of the image. Although small, but easily discernable, multiple red knots of nebulosity are visible near the center of LDN 1634. These constitute a flow of Herbig Haro objects, tiny jets launched by young protostars that glow by being collisionally excited.   The largest of these is known as RNO 40 and the RNO catalogue of 'red nebulous objects' was published by the astronomer Martin Cohen in 1980. The RNO 40 outflow is driven by a protostar called IRAS 05173-0555 and is also catalogued as HH 240.   Professional studies have concluded that Sh2-278 is either a remnant of the gas in the Orion Molecular Cloud that formed the Orion OB1 association or a cloud that was pushed to its current location by the winds and pressure of the OB association. In the sky, it is located north of Rigel."   https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1518643760441-I7EFB9YMLTFEUM0B7V1U/LBN670APODsmall.jpg Nebula - SFO 11 in the Soul Nebula (SWO) SFO 11,11NE,11E in LBN 670 You can see many of the bright rimmed globules clearly, these are the result of UV radiation and winds from hot young stars that have had an effect on the gas around them.

In particular, this beautiful grouping of reflection nebulae in Orion - NGC 1977, NGC 1975, and NGC 1973 - are usually overlooked in favor of the substantial glow from the nearby stellar nursery better known as the Orion Nebula. Found along Orion's sword just north of the bright Orion Nebula complex, these reflection nebulae are also associated with Orion's giant molecular cloud about 1,500 light-years away, but are dominated by the characteristic blue color of interstellar dust reflecting light from hot young stars. North is down in this sharp color telescopic image from New South Wales, Australia, so the more familiar Orion Nebula borders the top of the view. NGC 1977 stretches across the field just above center, separated from NGC 1973 (below left) and NGC 1975 (below right) by darker regions of obscuring dust. Many northern hemisphere observers claim to see the general shape of a running man in the cosmic dust cloud but, of course, they're looking at the view upside down. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1517606679362-BYF7DL9L9BI96M12JETK/NGC+1999+ApodSmall.jpg Nebula - NGC 1999 (SWO) Explanation: South of the large star-forming region known as the Orion Nebula, lies bright blue reflection nebula NGC 1999. At the edge of the Orion molecular cloud complex some 1,500 light-years distant, NGC 1999's illumination is provided by the embedded variable star V380 Orionis. That nebula is marked with a dark sideways T-shape near center in this cosmic vista that spans about 10 light-years. The dark shape was once assumed to be an obscuring dust cloud seen in silhouette against the bright reflection nebula. But recent infrared images indicate the shape is likely a hole blown through the nebula itself by energetic young stars. In fact, this region abounds with energetic young stars producing jets and outflows with luminous shock waves. Cataloged as Herbig-Haro (HH) objects, named for astronomers George Herbig and Guillermo Haro, the shocks look like red gashes in this scene that includes HH1 and HH2 just below NGC 1999. The stellar jets push through the surrounding material at speeds of hundreds of kilometers per second. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1513913741610-ZY59C1XBHDLNOGLMMSG5/NGC+1579Apod.jpg Nebula - NGC 1579 (SWO) Explanation: Colorful NGC 1579 resembles the better known Trifid Nebula, but lies much farther north in planet Earth's sky, in the heroic constellation Perseus. About 2,100 light-years away and 3 light-years across, NGC 1579 is, like the Trifid, a study in contrasting blue and red colors, with dark dust lanes prominent in the nebula's central regions. In both, dust reflects starlight to produce beautiful blue reflection nebulae. But unlike the Trifid, in NGC 1579 the reddish glow is not emission from clouds of glowing hydrogen gas excited by ultraviolet light from a nearby hot star. Instead, the dust in NGC 1579 drastically diminishes, reddens, and scatters the light from an embedded, extremely young, massive star, itself a strong emitter of the characteristic red hydrogen alpha light. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1512581104759-I9HCCLQWNZP49PTN4RAZ/M15webApod.jpg Nebula https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1512581051700-AKKWG6S4S6J4WU2NRI8D/IC1805PillarCrop.jpg Nebula - IC 1805, Pillar of Creation (SWO) "The Lost Pillar of Creation"   Most know of the "Pillars of Creation,” which is a famous image from the Hubble Space Telescope, but few know of this hidden pillar. What a gem! This “no name” pillar is all alone in the dark shadows of the Heart and Soul Nebula. In between open cluster NGC 1024 and IC 1805, the pillar itself looks like a finger pointing to the wonderful Melotte 15 Nebula at the center of IC 1805. A beautiful, but quite faint object. It needs long Ha exposures to really make it pop out.   https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1512436843313-D1J8ZBVUD0KW1PB4SF55/LBN762FinishedCropedapod.jpg Nebula - LBN 762 (SWO) Although very photogenic and well placed for northern observers these two objects are rarely imaged: LBN 762 / MBM13 dubbed the Drunken Dragon Nebula can be seen in this image. This field is located in Aries just south of MBM12.This relatively young association of gas and dust is home to an early stellar nursery and a few newborn stars . Once believed to be the nearest dust cloud from our solar system it is now suggested to be about 850 light-years away.The structure of LBN 762 is quite amazing, one must wonder what forces are at play to create such intricate features. Numerous background galaxies are visible, some even through relatively dense part of the translucent clouds. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1509646043305-N4TQS2SEMPYWTLRSGE4S/IrisNebulaFinishedApodSmall.jpg Nebula - Iris Nebula-NGC 7023 (SWO) These cosmic clouds have blossomed 1,300 light-years away, in the fertile starfields of the constellation Cepheus. Called the Iris Nebula, NGC 7023 is not the only nebula to evoke the imagery of flowers, though. Still, this deep telescopic image shows off the Iris Nebula's range of colors and symmetries, embedded in surrounding fields of interstellar dust. Within the Iris itself, dusty nebular material surrounds a hot, young star. The dominant color of the brighter reflection nebula is blue, characteristic of dust grains reflecting starlight. Central filaments of the reflection nebula glow with a faint reddish photoluminesence as some dust grains effectively convert the star's invisible ultraviolet radiation to visible red light. Infrared observations indicate that this nebula contains complex carbon molecules known as PAHs. The pretty blue petals of the Iris Nebula span about six light-years. The colorful field-of-view stretches almost five Full Moons across the sky. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491960945026-P2CNTY3OJTRQ5CIEEX8L/Gum20finished4-6-17.jpg Nebula - Gum 20 from SSRO https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491434726953-MJB5TJQE388Y906XBWAN/VDB-38Finished.jpg Nebula - VDB 38 from Stellar Winds Observatory-DSNM https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491434683173-SWVWIL3TQW04E18D341U/NGC+2023+Final.jpg Nebula - NGC 2023 from SSRO in Cito, Chile https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491434742421-OVXHXJB9IB17UXEGKMT3/NGC346+FinishedNew.jpg Nebula - NGC 346 (SSRO Cito, Chile) https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491434704134-I5KOXR7OSDRQTYUST783/NGC281+Astronomymag.jpg Nebula - NGC 281 LRGB (SRO-California) https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491433472885-II2DUAZPVDPWH8TV1XZZ/IC50707filterWeb.jpg Nebula - IC 5067 The Pelican (Narrowband) https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491434670611-SP1DJU7QUQYO6VC3IUC5/281Narrow.jpg Nebula - NGC 281 Narrowband (SRO-California) https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491433453332-VWDV18TWWEZYTYGI10RI/IC5070LRGB.jpg Nebula - IC 5067 The Pelican https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491434704671-CUE6VHXP6G2HQ3350B9Z/BokGlobsAPYMarkHanson.jpg Nebula - NGC 2237 Bok Globules in the Rosette Nebula https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491433415983-JENFIV5C03CADQ567BOT/IC410+All.jpg Nebula - IC 410 The Tadpoles https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491433440147-4MQEMNHL81Q1F08HO2YL/IC1805+DOneweb.jpg Nebula - Melotte 15 (Rancho Hidalgo-DGRO) https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491433370841-BNWBQX66NH4TKGOHIRPI/APODNGC6823.jpg Nebula - NGC 6823 https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491433479482-NMWXI235STHQP7PRK2QK/LBN777FinalFlat.jpg Nebula - LBN 777 The Baby Eagle https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491433501871-FVLKQ8UTEILGT7SMO0RG/M17Web.jpg Nebula - M 17, The Swan or Omega Nebula https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491433552110-J7GJ9UR5C9GOP3RPQRQ6/M20MarkfinalWeblarge.jpg Nebula - M20, Trifid Nebula https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491433574682-1BENTABNTQK1R8ZWM9A1/NGC1333Web.jpg Nebula - NGC 1333 https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491433565287-5QLROA54U9GGBDLDWUDK/NGC1555+Finished10.jpg Nebula - NGC 1555, 1554 Hind's Variable Nebula https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491433508871-IIGKNTOO2SUGH4XI9N0D/LDN1622Final3.jpg Nebula - LDN 1622 Dark Nebula https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491433396543-RJFM3WVCQYQ1XVG4QHJX/CaveJPG.jpg Nebula - Cave Nebula, Caldwell 9, SH2-155 https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491433601851-GTJASTUSBOWGPC0K4OG7/TheWallFinal3Web.jpg Nebula - NGC 7000, The Wall https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491433622149-70SOVIL2MDI4TTRS4U5E/VDB143Web.jpg Nebula - VDB 142, Elephants Trunk Nebula https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1491433383956-PRYKTFFQH6UKGJWTCPZN/Astronomyconefox.jpg Nebula - Cone and Fox Fur Nebula, NGC 2264 Cone and Fox Fur Nebula Mosaic Taken from DGRO Rancho Hidalgo Animas, New Mexico 14.5" RCOS F8, Apogee U16M High Cooling HA 390 min S2 330min O3 300min Red 135min Green 105min Blue 135min Calibrated,combined in CCD Stack all other processing done using PS5.

This image here includes the entire outer shell and is the only image of this I could find. The outer structures around this planetary nebula were discovered by the Galactic Planetary Nebula Halo Survey (GPNHS) team in May 2016. This planetary nebula represents a fleeting, poetic moment in the life cycle of a star similar to our own Sun. As the central star reached the end of its nuclear fuel, it gently shed its outer layers into the cold vacuum of space, creating a shimmering, translucent shell of ionized gas. Unlike the violent cataclysms of supernovae, this expansion is a graceful transition, where the exposed, scorching-hot core—a fledgling white dwarf—floods the surrounding nebula with ultraviolet light, causing it to glow with a soft, ethereal radiance. Visually, Longmore 8 is a testament to the intricate symmetry found in the cosmos. Often appearing as a faint, circular, or slightly elliptical smudge against the dense star fields of the Milky Way, its subtle structure reveals the complex interplay between stellar winds and magnetic fields. Because it is relatively low in surface brightness, it remains a hidden gem, typically reserved for the long-exposure eyes of large telescopes rather than a casual glance. To study this nebula is to look into the far-distant future of our own solar system, capturing a final, beautiful exhale of a star before it fades into the dark permanence of a stellar remnant.

Its vibrant display of colors—yellow for sulfur, red for hydrogen, and blue oxygen—maps out the last emissions of a star as it sheds its outer layers. These elements enrich the nearby interstellar space, providing material that may form new stars and planets in the future. Situated about 3,000 light-years away within the constellation Musca, NGC 5189 has earned the name Spiral Planetary Nebula due to its dramatic, complex swirls of luminous gas. Unlike the typical bubble-shaped envelopes seen around dying stars, this nebula presents a chaotic landscape filled with twisted strands and knots spanning distances similar to our solar system. The nebula’s distinctive shape results from the gravitational interplay between the two central stars: a hot Wolf-Rayet star—the exposed core of a faltering sun—and its companion, a compact white dwarf. With an orbital period of just a few days, their interaction produces shifting axes reminiscent of a spinning lawn sprinkler, ejecting material outward in various directions. This phenomenon, called precession, sculpts the unique, symmetrical lobes that give NGC 5189 its spiral, galaxy-like appearance. Imaged in RGBHa on a Planewave CDK 24 at Observatorio El Sauce, Chile.

Thousands of comet-Like filaments likely formed when hot stellar winds and radiation plowed into colder shells of gas and dust. Some stars die slowly, giving off puffs of gas and dust known as planetary nebulas to reveal small white dwarfs. Much larger stars die suddenly in powerful explosions known as supernovas, blasting gas, dust, and energy out in all directions as they collapse to form tiny neutron stars or black holes. The gas and dust expelled by dying stars eventually combines with the remains of others to form new stars, planets, and moons. As the dying star at the center of the Helix Nebula exhausted its fuel, it threw off its outer layers as a gaseous wind and transformed into a white dwarf. As the glowing shells of gas expand over 10,000 years, they eventually thin out and become part of the interstellar medium. Planetary nebulas provide a snapshot of a transitional phase in the life and death of a star.

NGC 2867 (also known as Caldwell 90) is an elliptical Type II planetary nebula in the southern constellation of Carina, just over a degree to the NNW of the star Iota Carinae. John Herschel discovered the discovery on April 1, 1834. Herschel initially thought he might have found a new planet, but on the following night he checked again and discovered it had not moved. The nebula is located 7,270 light-years from the Sun. Caldwell 90 was formed in the late stages of the development of a Sun-like star. Following the nuclear fusion of hydrogen into helium in its core, the star underwent a series of energy crises when its supply of hydrogen began to decline. Without the outward force previously created by the energy production, gravity shifted and caused the star's core to contract. The extra pressure allowed the star to produce a heavier substance in its core. The synthesis of carbon produced a lot more energy than the fusion of hydrogen into helium, which enabled the star to not only overcome gravity to expand once more but led the star to become a red giant. Eventually the red giant’s outer layers of gas were ejected. Meanwhile, the star transformed from a cool giant into a hot, dense star that radiates ultraviolet light and a fast wind of particles that move outward at around 6 million miles per hour. The stellar wind and ultraviolet light interact with the layers of gas that the red giant ejected to create the glowing, spherical shell we see today.

It was discovered by Heckathorn, Fesen and Gull in 1983. It is in the southern constellation of Puppis about 6,000 light years distant. This planetary nebula is oval with a unique shape, to me it looks like a sponge from the ocean. Notice the faint but very apparent extended OIII halo structure forming around the spheroid of this very interesting object. The Ha emissions look like they are interacting with HFG-2, but have found no information that supports this anywhere, not sure if they or not.

It is moving away from us at 49 kilometers per second. Despite their name, planetary nebulae have nothing to do with planets. The name of planetary nebulae arose because of the visual similarity between some round planetary nebulae and the planets Uranus and Neptune when viewed through early telescopes. When a star with a mass up to eight times that of the Sun approaches the end of its life, it blows off its outer shells and begins to lose mass. This allows the hot, inner core of the star to radiate strongly, causing this outward-moving cocoon of gas to glow brightly as a planetary nebula. Over the next several thousand years, the nebula will gradually disperse into space, and then the star will cool and fade away for billions of years as a white dwarf. Our own Sun is expected to undergo a similar fate, but fortunately this will not occur until some 5 billion years from now. There are two stars close together — a binary system — in the center of NGC 3132, one of 10th magnitude, the other 16th. It’s the dim star, not the bright one, near the center that caused multiple outbursts and originated the intricate, somewhat concentric structure of the nebula. This hot central star is a white dwarf of about 100,000 K that has now blown off its layers and is making the nebula fluoresce brightly from the emission of its intense ultraviolet radiation. This expanding cloud of gas is one of the nearest known planetary nebulae. The gases are expanding away from the central star at a speed of about 14.4 kilometers per second. Neither the unusual shape of the surrounding cooler shell nor the structure and placements of the cool filamentary dust lanes running across NGC 3132 are well understood. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1698192355676-OW61K5XRND3632F1FU3P/image-asset.jpeg Planetary Nebula - M46 & Planetary Nebula NGC 2438 M46 & Planetary Nebula NGC 2438 Messier 46 or M46, also known as NGC 2437, is an open cluster of stars in the slightly southern constellation of Puppis. It was discovered by Charles Messier in 1771. Dreyer described it as "very bright, very rich, very large." It is about 5,000 light-years away. There are an estimated 500 stars in the Cluster. NGC 2438 is a planetary nebula (Left Center) The central star is roughly 1,370 light years. So closer than M46 cluster. This is a multi-shell planetary nebula with a bright inner nebula consisting of two somewhat detached shells. The structure is surrounded by a fainter, mostly circular halo. The nebula consists of material ejected from the central star. The main nebula was formed at about half that age. The central star of this planetary nebula is one of the hottest stars known.

Type I (helium and nitrogen rich) planetary nebula by Peimbert classification [5], He 2-111 has a planar bipolar asymmetrical shape, which is found to be likely shaped by a triple stellar system in [3, 4]. With estimated distance to the nebula of about 6.8 kly [1-2] and long axis angular length of about 10’ the diameter if the “lobes” corresponds to about 20 ly and the long axis of the core of the nebular of about 30” corresponds to about 1 ly. Thus, the nebula lies much further away than HD 127470 star (830 ly away) - the brightest star in the frame above the core of He 2-111, but roughly at the same distance as a nearby NGC 5617 open cluster (6.5 kly). The central star (or rather central stars) of this nebula have never been observed, but its core reveals a complex structure featuring a toroid placed at about 45 deg inclination to the plane of the “lobes”, with the outer diameter along the major axis of 20” and inner diameter along the same axis of 14” or 0.7 ly and 0.5 ly of linear size correspondingly, based on the best available distance estimates from above. This toroidal structure in the core turned out to be best visible in the SII channel, and adding it to the exposure set allowed to boost visibility of fine details in the core compared to HO(L)RGB images of this object obtained earlier. Two sets of “spokes” are reaching out from the core of the nebula to the periphery which consists of fast moving radially extended “knots” of material for which the radial velocity is found to be reaching 650 km/s which put the age of the nebula in the range of 8-20 ky depending on the model of the expansion [1, 2]. A peculiar cusp-like structure is visible next to one of the “spokes” on the left from the core, revealed in a fully connected way in this image, likely for the first time. Extended diffuse structures visible on the outer side of the lobes of the nebula (best visible in the starless version of the image) - also likely for the first time.

At that time, Charles Messier was compiling a list of diffuse objects not to be confused with comets. The 27th object on Messier's list, now known as M27 or the Dumbbell Nebula, is a planetary nebula, the type of nebula our Sun will produce when nuclear fusion stops in its core. M27 is one of the brightest planetary nebulae in the sky, and can be seen toward the constellation of the Fox (Vulpecula) with binoculars. It takes light about 1000 years to reach us from M27. Understanding the physics and significance of M27 was well beyond 18th century science. Even today, many things remain mysterious about bipolar planetary nebula like M27, including the physical mechanism that expels a low-mass star's gaseous outer-envelope, leaving an X-ray hot white dwarf.

Surrounded by Milky Way stars and near the line-of-sight to distant background galaxies, its generally simple spherical shape, about 8 light-years in diameter, is outlined in this deep telescopic image. Within its confines are beautiful, more complex details enhanced using narrowband filters. Emission from hydrogen and nitrogen is shown in reddish hues with oxygen emission mapped to a bluish-green color, giving Abell 7 a more natural appearance that would otherwise be much too faint to be appreciated by eye. A planetary nebula represents a very brief final phase in stellar evolution that our own Sun will experience 5 billion years hence, as the nebula's central, once sun-like star shrugs off its outer layers. Abell 7 itself is estimated to be 20,000 years old. Its central star is seen here as a fading white dwarf some 10 billion years old. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1640463907923-77DT83MDASM7JDC1M1Z0/image-asset.jpeg Planetary Nebula - NGC 1360 The Robin's Egg Nebula This pretty cosmic cloud lies some 1,500 light-years away, it shape and color reminiscent of a blue robin's egg. It spans about 3 light-years, nested securely within the boundaries of the southern constellation Fornax. Recognized as a planetary nebula, NGC 1360 doesn't represent a beginning though. Instead, it corresponds to a brief and final phase in the evolution of an aging star. In fact, visible in the telescopic image the central star of NGC 1360 is known to be a binary star system likely consisting of two evolved white dwarf stars, less massive but much hotter than the Sun. Their intense and otherwise invisible ultraviolet radiation has stripped away electrons from the atoms in the surrounding gaseous shroud. The predominant blue-green hue of NGC 1360 seen here is the strong emission produced as electrons recombine with doubly ionized oxygen atoms. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1584101808943-ZWP2HP7429FUC6FOG4IC/SH2-200Thumb.jpg Planetary Nebula - HDW 2 (Sh2-200) HDW 2 (Sh2-200): This exquisitely detailed image is a portrait of the planetary nebula HDW 2, which is located towards the royal constellation of Cassiopeia. Consisting of iridescent shades of purple and blue, this ethereal bubble represents the ghostly remains of a dying star. The category of planetary nebulae was given its name due to telescopic observations by 18th century astronomers such as William Herschel and others being described as similar in appearance and brightness to planets. In astronomy, many things are named after their resemblance to something. HDW 2 is a very faint ancient planetary nebula of low surface brightness, therefore making telescopic observations very difficult. Faint planetary nebulae such as this one are best appreciated in detailed astrophotographs such as this one and even then, long exposures of many hours are still required. Whilst in the past planetary nebulae might have been discovered through direct visual observations, the many discoveries made in the 21st century have been through photographic means. Some discoveries have been made by professionals as part of large scale surveys such as the Ear Nebula and some discoveries have been due to amateur astrophotographers such as the Soap Bubble Nebula. This nebula was first discovered by the astronomer Stewart Sharpless in 1959 who included it in his catalogue of HII regions under the name of Sh2-200. His catalogue was compiled after analysing photographic plates taken at the Palomar Observatory. The misidentification of HDW 2 (or Sh2-200) arose from the criteria of assembling the catalogue, which compared the separate red and blue photographic plates of the same region. If a nebula was more prominently visible on the red plate, it was deduced that it was more likely to be an ionized nebula. The other criteria was the presence of bright stars in the vicinity, which might be the source of ionization. Despite increasing the number of catalogued and known deep sky objects, the method of analysing monochromatic photographic plates displayed its limitation with the incorrect classification of nebulae with a number of entries in the Sharpless catalogue of HII regions subsequently being found to belong to different categories of objects such as planetary nebulae, supernova remnants, Wolf Rayet nebulae, high latitude dust clouds and even galaxies. In 1983, Sh2-200 was included in the HDW catalogue of possible planetary nebulae by the astronomers Herbert Hartl, Johann Dengel and Ronald Weinberger. However it wasn't confirmed to be a true genuine planetary nebula until 2017 when spectra was taken as part of professional observations. In 1987, further narrowband observations by Herbert Hartl and Ronald Weinberger detected a large faint outer halo extending further than the central shell. A feature not fully appreciated or clearly defined in the scientific literature is something known as ISM-type haloes. These are a type of structure that represent ambient interstellar gas in the vicinity of the planetary nebula but not physically related to it. Despite being very old and highly evolved, low surface brightness planetary nebulae such as HDW 2 contain very hot and energetic central stars, which are the remnant cores of the progenitor star that died and ejected its outer gaseous layers. The energy output of some planetary nebula central stars is so prodigious that it is capable of ionizing unrelated gas in the surrounding vicinity causing it to glow. The most popular example of this phenomenon is the large halo around NGC 3242. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1581115562802-3V611NW0YYUUWM56ZB46/A8Crop.jpg Planetary Nebula - Abell 8 Abell 8 is a 1 arcminute planetary nebula consisting of a Ha bright rim and an OIII interior. Deep narrowband images such as this one show extended clouds of hydrogen in the vicinity. This isn't material ejected by the progenitor star but ambient material in the surrounding interstellar medium (ISM) that is being ionized by ultraviolet radiation of the central star leaking out of the thin gaseous shell of the planetary nebula. Abell 8 was discovered by the astronomer George Abell in 1955. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1572439424938-422ZBC97R73GV48O6TR0/Abell78-4Crop.jpg Planetary Nebula - Abell-78 Abell 78 This planetary nebula has the unusual property of having a faint outer halo composed of normal stellar material (mostly hydrogen) and a bright inner elliptical ring composed mostly of helium. The helium ring provides direct confirmation that hydrogen is being converted to helium in the centers of stars and can later be ejected back into the galaxy's pool of gas for building another generation of enriched stars.

Astronomers have modeled the three-dimensional structure of the nebula, finding it to be a cloud shaped as an irregular ellipsoid filled with bumpy and bubbly regions. It has a bright central star that can be seen easily in this image, shining brightly from within the nebula’s cloud. This bright pearl embedded within its glowing shell inspired the nebula’s popular nickname: the Oyster Nebula. While NGC 1501's central star blasted off its outer shell long ago, it still remains very hot and luminous, although it is quite tricky for observers to spot through modest telescopes. This star has actually been the subject of many studies by astronomers due to one very unusual feature: it seems to be pulsating, varying quite significantly in brightness over a typical timescale of just half an hour. While variable stars are not unusual, it is uncommon to find one at the heart of a planetary nebula. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1551406760774-FBMG64F2D3Y42G8XC7NI/M76100crop.jpg Planetary Nebula - M76 Explanation: "Nebula at the right foot of Andromeda ... " begins the description for the 76th object in Charles Messier's 18th century Catalog of Nebulae and Star Clusters. In fact, M76 is one of the fainter objects on the Messier list and is also known by the popular name of the "Little Dumbbell Nebula". Like its brighter namesake M27 (the Dumbbell Nebula), M76 is recognized as a planetary nebula - a gaseous shroud cast off by a dying sunlike star. The nebula itself is thought to be shaped more like a donut, while the box-like appearance of its brighter central region is due to our nearly edge-on view. Gas expanding more rapidly away from the donut hole produces the fainter loops of far flung material. The fainter material is emphasized in this composite image, highlighted by showing emission from hydrogen atoms in orange and oxygen atoms in complementary blue hues. The nebula's dying star can be picked out in the sharp false-color image as the blue-tinted star near the center of the box-like shape. Distance estimates place M76 about 3 to 5 thousand light-years away, making the nebula over a light-year in diameter. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1548344099920-UAFOROK15MVFS7SMYE7K/100%25CropBubble.jpg Planetary Nebula - Bubble Nebula - NGC 7635 From GBO NGC 7635, also known as the Bubble Nebula, Sharpless 162, or Caldwell 11, is a H II region[1] emission nebula in the constellation Cassiopeia. It lies close to the direction of the open cluster Messier 52. The "bubble" is created by the stellar wind from a massive hot, 8.7[1] magnitude young central star, SAO 20575 (BD+60°2522).[7] The nebula is near a giant molecular cloud which contains the expansion of the bubble nebula while itself being excited by the hot central star, causing it to glow.[7] It was discovered in 1787 by William Herschel.[5] The star BD+60°2522 is thought to have a mass of about 44 M☉. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1545934007483-3WTZHLD6LLU82AQW2PKJ/NGC40FullCrop.jpg Planetary Nebula - NGC 40-CTA1 "NGC 40 is a bright planetary nebula consisting of a detailed core with an outer halo. This halo consists of a double structure with a diffuse inner halo attached to the central shell and a more irregular filamentary structure, which extends to the north. In addition to these array of features is a structure to the south, which has been interpreted as a jet. Professional observations with the Spitzer infrared telescope have shown the inner halo to consist of multiple overlapping radial spoke ring structures. This halo was discovered in 1987. The central star of this planetary nebula has been well studied by professional astronomers and is also interesting in its own right. It belongs to the Wolf Rayet subclass of planetary nebula central stars that are hydrogen deficient and exhibit high mass loss rates and strong stellar winds. WR type central stars have been identified in a number of other planetary nebulae including IC 4663 and Abell 48. Extending along the contours of the full field of this image are multiple colourful filaments belonging to the large faint supernova remnant CTA 1, which covers an area of 1.5 degrees across the sky. Both NGC 40 and CTA 1 are physically unrelated with the supernova remnant lying more distant in the background. NGC 40 is 3500 light years away and CTA 1 is 4500 light years away." https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1528984744235-HODZRP8CX5TIPQJNYFMM/Cats+Eye+Nebula+Crop.jpg Planetary Nebula - Cats Eye Nebula (SWO) Explanation: The Cat's Eye Nebula (NGC 6543) is one of the best known planetary nebulae in the sky. Its more familiar outlines are seen in the brighter central region of the nebula in this impressive wide-angle view. But the composite image combines many short and long exposures to also reveal an extremely faint outer halo. At an estimated distance of 3,000 light-years, the faint outer halo is over 5 light-years across. Planetary nebulae have long been appreciated as a final phase in the life of a sun-like star. More recently, some planetary nebulae are found to have halos like this one, likely formed of material shrugged off during earlier episodes in the star's evolution. While the planetary nebula phase is thought to last for around 10,000 years, astronomers estimate the age of the outer filamentary portions of this halo to be 50,000 to 90,000 years. Visible on the left, some 50 million light-years beyond the watchful planetary nebula, lies spiral galaxy NGC 6552. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1521493735586-ND5TGFE9UAYXP0NYMUIP/Cava1Aopdsmall.jpg Planetary Nebula - CaVa 1 Planetary Nebula (SWO) "CaVa 1 is an obscure ancient planetary nebula that was discovered by the French amateur astronomers Jean-Paul Cales and Michael Vanhuysse in 2017. It has a size of 8x7 arcminutes and is located in a region of background nebulosity. There is sometimes a relation between the size of a planetary nebula, its age and its relative faintness. Older planetary nebulae over time eventually expand more and the ionizing energy is spread over a larger area as well as the density of the gas being thinner, so therefore exhibit lower surface brightness. This is easily overcome by amateur astronomers who are able to obtain very long exposures. Large low surface brightness planetary nebulae have been discovered in professional Ha surveys and also by amateurs analysing various astronomical survey data.   CaVa 1 consists of primarily Ha emission with some OIII in its interior. The southern part exhibits a tenuous bowshock structure produced by its interaction with the surrounding interstellar medium (ISM). Few examples of planetary nebulae with ISM interaction are known due to their extremely low intrinsic brightness. This stage in the evolution of a planetary nebula precedes the total dilution and fading of a planetary nebula. However, the phenomenon of ISM interaction has been observed in young planetary nebulae with high speed central stars and studies conclude that different stages of interaction are exhibited throughout the life of planetary nebulae. The idea of a planetary nebula interacting with the ISM as it moves through space was proposed in 1969 by the Armenian astronomer Grigor Gurzadyan." https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1515010604180-OXIGA74V95TX04YF31LY/PuWe1O3ACrop.jpg Planetary Nebula - PuWe1 (PNG 158.9 + 17.8), in Lynx (SWO) PuWe1 (PNG 158.9 + 17.8), in Lynx, is one of the largest PN, that has an apparent diameter of 20'. It has been discovered by Purgathofer & Weinberger in 1980 on a Palomar sky survey print. As almost all this kind of old diluted PN, it is very faint and requires long exposures to get details. The Halpha signal is the strongest and draws a ring with several details in the structure while the OIII signal is extremely faint with a disc shape and no visible structure. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1512137021193-MJ8QM9OTWMOD5G181HJT/PK164%2B31HALRGBO3centercrop.jpg Planetary Nebula - PK 164+31.1 Jones-Emberson 1 (SWO) PK 164+31.1 Jones-Emberson 1 Explanation APOD: Is this what will become of our Sun? Quite possibly. The bubble of expanding gas pictured above is the planetary nebula PK 164 +31.1, the remnants of the atmosphere of a Sun-like star expelled as its supply of fusion-able core hydrogen became depleted. Visible near the center of the nebula is what remains of the core itself -- a blue-hot white dwarf star. This particularly photogenic planetary nebula shows intricate shells of gas likely expelled at different times toward the end the star's demise, and whose structure is not fully understood. This deep image of PK 164 +31.1 shows many other stars from our own Milky Way Galaxy as well as several galaxies far in the distance. PK 164 +31, also known as Jones-Emberson 1, lies about 1,600 light years away toward the constellation of the Wildcat (Lynx). Due to its faintness (magnitude 17) and low surface brightness, the object is only visible with a good-sized telescope. Although the expanding nebula will fade away over the next few thousand years, the central white dwarf may well survive for billions of years -- to when our universe may be a very different place.

It was spectroscopically confirmed as a true planetary nebula by the professional astronomer Laurence Sabin in September 2011. It has also been independently discovered by the French amateur astronomer Laurent Ferrero in 2013 and is also known as Fe 6. Its structure consists of a low surface brightness bubble with a size of 3.5 arcminutes, which is accentuated by a thin "bright" rim on the outside. It is very likely to be an ancient evolved planetary nebula that is interacting with the interstellar medium (ISM) and its intensely blue central star is easily visible near the centre. Despite its faintness, it is possible to visually observe it in very large telescopes. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1506974085774-1HYXVZRA1TNWHZ169IIG/SoapBubbleAPODCrop.jpg Planetary Nebula - The Soap Bubble Nebula PN G75.5+1.7 (SWO) The Soap Bubble Nebula PN G75.5+1.7   Explanation From APOD: Adrift in the rich star fields of the constellation Cygnus, this lovely, symmetric nebula was only recognized a few years ago and does not yet appear in some astronomical catalogs. In fact, amateur astronomer Dave Jurasevich identified it as a nebula on 2008 July 6 in his images of the complex Cygnus region that included the Crescent Nebula (NGC 6888). He subsequently notified the International Astronomical Union. Only eleven days later the same object was independently identified by Mel Helm at Sierra Remote Observatories, imaged by Keith Quattrocchi and Helm, and also submitted to the IAU as a potentially unknown nebula. The nebula s now known as the Soap Bubble Nebula. Most probably it is a planetary nebula, a final phase in the life of a sun-like star. https://images.squarespace-cdn.com/content/v1/57e97e6ab8a79be1e7ae0ae6/1503853597434-EJFI8Z6LVEITH2O3ZWPL/M57LRGBHAThumb.jpg Planetary Nebula - M57 The Ring Nebula (SWO) The Ring Nebula (also catalogued as Messier 57, M57 or NGC 6720) is a planetary nebula in the northern constellation of Lyra.
