M27 Dumbbell Nebula
The M27 Dumbbell Nebula is a planetary nebula about 1360 light-years from us. It stetches about 1 1/2 light-years across. Like all planetary nebulas, it is formed by emissions from a white dwarf star in its center. Bright enough to be seen through binoculars, the fainter outer wings that from the dumbbell shape usually require a small to mid-sized telescope. North is at the bottom.
