NGC 3521 “Marquise in the Sky”

Like a big solitaire marquise diamond, this wonderful nighttime galactic gem is 35 million light years away in the constellation Leo.

 A flocculent intermediate spiral galaxy, NGC 3521 lacks the clearly defined arm structure that we see in some other spirals. Surrounded by dust, the galaxy has numerous star-forming areas and a luminous center. The dust bubbles are likely from encounters and mergers long ago with satellite galaxies.

 Also, notice the rarely seen Hydrogen Alpha jets emanation from this galaxy.
