M57 – Ring nebula
in Lyra
The Ring Nebula (also catalogued as Messier 57, M57 and NGC 6720) is a planetary nebula in the northern constellation of Lyra. Such a nebula is formed when a star, during the last stages of its evolution before becoming a white dwarf, expels a vast luminous envelope of ionized gas into the surrounding interstellar space. This nebula was discovered by the French astronomer Charles Messier while searching for comets in late January 1779. From Wikipedia.
