The Southern Pinwheel Galaxy, also known as Messier 83 (M83), is a barred spiral galaxy located in Hydra constellation. M83 lies at a distance of 15 million light years from Earth. It is one of the nearest and brightest spiral galaxies, and can even be seen in binoculars. The galaxy appears face-on when viewed from Earth.
Messier 83 was nicknamed the Southern Pinwheel Galaxy because of its prominent, very well defined spiral arms, which give the galaxy an appearance similar to the famous Pinwheel Galaxy (Messier 101), located in Ursa Major. Messier 83 has the designation NGC 5236 in the New General Catalogue.
