The Dumbbell Nebula
The Dumbbell Nebula (M27) is what’s called a planetary nebula – but it has nothing to do with a planet. This shell of gas was blown out by a dying star; once it started to run out of Hydrogen to burn, it expanded and blew out the gases you see here. The star then collapsed into a white dwarf, slowly burning what’s left of it at the nebula’s center. Our own sun is expected to do the same in a few billion years.
