The Southern Pinwheel Galaxy, catalogued as Messier 83 and also designated NGC 5236, is a barred spiral galaxy about 15 million light-years away on the border of the constellations Hydra and Centaurus. It was discovered by the French astronomer Nicolas-Louis de Lacaille on 17 February 1752 from the Cape of Good Hope, and Charles Messier later added it to his catalogue of nebulous objects in March 1781.
