The galaxy Messier 83 (M 83) is located in the constellation Hydra. It is also known as the NGC 5236 galaxy or the Austral del Molinillo galaxy. It was discovered in 1752 by the French astronomer Pierre Mechain at the Cape of New Hope.
Messier 83 is 15 million light-years away from Earth, and is a barred spiral galaxy. It has an extension of more than 40 thousand light years, which represents only 40 percent of the size of the Milky Way. Despite this, it closely resembles our galaxy, both because of its spiral shape and the presence of a strip of stars that crosses its center.
In the Messier 83 galaxy, six supernovae have been detected so far between 1945 and 1983. For a long time it was considered that M83 was the galaxy that had the most supernovae, but the discovery of the NGC 6946 galaxy exceeded this number, with a total of Eight supernovae
The Messier 83 galaxy is an excellent example of a galaxy with a stellar outbreak, which is concentrated in its central zone containing several super star clusters. M83 is also rich in metals, and Wolf-Rayet-type stars abound there, in an estimated number of about 3,000.
