Description

The Dumbbell Nebula, M27, is a planetary nebula that lies some 1400 light years away in the constellation Vulpecula. It was the first planetary nebula discovered. Planetary nebulae consist of expanding ionized gas ejected from red giant stars. What's left is a very hot star, a white dwarf, and the UV radiation from the star ionizes the gas, providing the light we see.
