Spiral Galaxy M83
Fred Calvert / Cold Spring Observatory
Messier 83 is one of the most conspicuous spiral galaxies in the sky. Situated in the constellation Hydra, it is the southernmost galaxy in Messier's catalog and located approximately 15 million light years from Earth. Shining with the light of billions of stars and the ruby red glow of hydrogen gas, it is a beautiful example of a barred spiral galaxy
M83 stretches over 40 000 light-years across, making it roughly 2.5 times smaller than our own Milky Way. However, in some respects, Messier 83 is quite similar to our own galaxy. Both the Milky Way and Messier 83 possess a bar across their galactic nucleus, the dense spherical conglomeration of stars seen at the centre of the galaxies.
