M27. The Little Dumbbell Nebula
Planetary nebula in Perseo.

Discovered by Pierre Mechain in 1780, this nebula is one of the fainter Messier objects. It is also known as the Butterfly nebula or the Cork nebula. It resembles M27 and probably
its main body (the cork) is a bright elliptical ring situated edge on. The ring seems to be expanding at 42 Km/s. Along the axis perpendicular to this plane, the gas expand quicker to form the "wings" of the butterfly.

Distance to earth: 3,400 light years
Visual Magnitude: 10.1
More information: Messier index. M76
