M-27 (NGC-6583) is a large, bright planetary nebula located in the constellation of Vulpecula (The Fox). It is commonly called "The Dumbbell Nebula" due to the two opposing rounded lobes and the narrow waist of the brightest portion of the nebula. It was discovered by Charles Messier in 1764 and added to his catalog as number 27. It lies at a distance of 900 light years from Earth and is 2 light years in diameter. It is formed by an immense shell of gas that is being expelled by a dying star, which is now a white dwarf. It is just visible at the center of the object.
