Cassiopeia A-Supernova remnant
Explanation Via APOD: 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.
Celestial Mechanics of the Heart by “Sakib Rasool”
Oh dazzling star of brilliance
Your lustre has faded with the ravages of time
Gaseous interior release me into the infinite void
Let my droplets of iridescent joy cascade outwards
Into a sense of wonder and magic weaving a celestial path
Woven of light infused with the elements of creation
A joyous celestial tapestry has been constructed
By those that have the courage to look skywards
Gaze upon the infinite wonder of the cosmos
For one second is a blink in the eye of the unknowing
We shall all return to the imperishable stars

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.
