Messier 27: The Dumbbell Nebula

Cykon submitted this image of Messier 27, the Dumbbell Nebula, to the ISSC Discord: a planetary nebula formed from a dying star's outer layers, glowing in ionized hydrogen and oxygen roughly 1,360 light-years from Earth. It's one of the brightest planetary nebulae in the sky, and one of the easiest for astrophotographers to find.
