on Monday, October 10, 2016

M57 (NGC 6720) is probably one of the most recognizable Messier objects. It is a planetary nebula found in the constellation Lyra, referred to as the Ring Nebula, and lies about 2,300 light-years from Earth.
From Wikipedia, “Such objects are formed when a shell of ionized gas is expelled into the surrounding interstellar medium by a red giant star, which was passing through the last stage in its evolution before becoming a white dwarf.”
