The Dumbbell nebula (M27) is a planetary nebula located in the constellation of Vulpecula and lies somewhere near to 1300 light years away. The central star is a star that has died and now exists as a white dwarf. A white dwarf is one of the final states a star can achieve after it has exhausted its hydrogen fusing power, essentially it is a dead star. Around 95% of all stars are thought to one day evolve into white dwarfs after leaving the main sequence of star evolution. The white dwarf is created after the star expands into a red giant, shedding its outer layers to form the nebula that surrounds the star, eventually the star collapses under its own gravity to form a small and incredibly dense white dwarf.
