Description

The Pinwheel Galaxy (also known as Messier 101 or NGC 5457) is a face-on spiral galaxy 21 million light-years from Earth in the constellation Ursa Major. It was discovered by Pierre Méchain in 1781 and was communicated that year to Charles Messier, who verified its position for inclusion in the Messier Catalogue as one of its final entries.
