The Dumbbell Nebula (also known as a Messier 27, M 27, or NGC 6853) is a planetary nebula in the constellation Vulpecula, at a distance of about 1360 light years. It has a large angular diameter as a planetary nebula, about 8 x 5,6 arc minutes. (Rarely imaged outer halo is not included, it can be seen in my image. With an outer shell, the diameter is over 15'' (more than a size of the half a Moon))
Planetary nebulae are shells of gas shed by stars late in their life cycles after using up all of their nuclear fuel. The star then ejects a gaseous shell, which is illuminated by its extremely hot central star, a core left from the original star. n this image, the central star is clearly visible at very center of the nebula. M27's central star has a magnitude of 13.5 and is an extremely hot blueish dwarf with a temperature of about 85,000 K.
Our own star, the Sun, is expected to undergo the same process in a couple of billion years.
