Object Type: Planetary
nebula (Type 3+2)
M27 is one of the two most famous planetary nebulae in the northern sky, along with M57, the Ring Nebula. It was the first planetary nebula discovered, on July 12, 1764, by Charles Messier. The central star is magnitude 13.5, and can be glimpsed in a large aperture telescope at high power. The distance to M27 is not precisely known; estimates range from 490 to 3500 light-years. In a moderate-sized instrument it is a beautiful object, with a distinct bi-lobed shape, resembling that of an apple core.
