| | A planetary nebula in the constellation Perseus that resembles, but is smaller and fainter than, the Dumbbell Nebula; it also known as the Cork Nebula, Butterfly Nebula, and Barbell Nebula and was discovered by Pierre Méchain in 1780. | | | The bright bar-shaped main body (measuring 42" x 87"), is probably a slightly elliptical ring seen edge-on from only a few degrees off its equatorial plane. | | | Finally, there is a faint halo covering a region about 290" in diameter, consisting of material that was probably ejected in the form of stellar winds from the central star when it was still in its red giant phase. |

| | The Dumbbell Nebula is one of the brightest and best known examples of planetary nebulae in the sky. | | | "Planetary nebulae" got their name because in the early days of astronomy they looked like planets through the small and crude telescopes of the times. | | | This type of nebula is a star in the process of dying, but instead of collapsing on itself and exploding as a supernova, its mass and evolution dictates that it "break apart" more gently and slowly eject it's material in to space. |
