This is Messier 83, located in the southern constellation Hydra (the Water Snake). It’s also known as NGC 5236 and as the Southern Pinwheel galaxy. It’s well-defined arms are typical of a spiral galaxy, much like our Milky Way. They have abundant young stars and are known to be a site of vigorous star formation. The newest generations of stars in M83 are forming largely in clusters, the pinkish clumps, on the edges of the dark, spiraling dust lanes. These brilliant, young stellar groupings are only a few million years old and produce huge amounts of ultraviolet light. That light is absorbed by the surrounding diffuse gas clouds, causing them to glow in pinkish hydrogen light. M83 has another distinction as having more supernovae explosions than any other Messier galaxy.
