Messier 27 (NGC6853, PK60-3.1), nebula sometimes also called the Dumbbell Nebula, belongs to a group of objects called planetary nebulae. These objects has nothing to do with planets and the designation refers to their spherical shape as seen in in small telescopes. This kind of objects results from the collapse of stellar objects with size of our Sun. Such collapse occurs after consumption of hydrogen "fuel" which is used for thermonuclear reaction of star.
