M83 is a Spiral galaxy 12 million lightyears away, in the Hydra constilation. This compound image was formed by combining images previously found on the Hubble Legacy Archive. The unique combination of dust and young stars in its spirals has led to this galaxy receiving the nickname 'The southern Pinwheel' for its resemblance to a pinwheel. The blue areas are regions of young stars, and the red regions are areas of star formation. Not only is the center full of old stars, but when viewed in the x-ray spectrum it is very bright, which means it is also full of neutron stars and black holes.
