The Ring Nebula (also catalogued as Messier 57, M57 or NGC 6720) is a planetary nebula in the northern constellation of Lyra.
One of the nearest of these is the Orion Molecular Cloud, whose dark cloak of dust and gas sprawls across 100 light-years of celestial real estate in southern Orion. The nebula we call M42 is a luminous âblisterâ about 25 light-years wide on the side of the Orion Molecular Cloud facing us.
