Astronomy Picture of the Day-M83
This is a Photo of the Southern Pinwheel Galaxy (also called as Messier 83 or M83 or NGC 5236) . It comes under the category of a barred spiral galaxy and is found in the constellation of Hydra. It is one of the brightest and closest barred spiral galaxies in the sky. Just about 15 million light years away!!?? It should be visible even with a pair of good binoculars but we are in the northern hemisphere and so it is a little difficult to find it since it stays low in the southern sky while viewing from our location.We’ll still try identifying it this winter during our astro camps. What makes it more difficult is the light pollution in the southern sky in our city. I’ve been trying to observe this galaxy for the last two years with no success.
Six supernovae (SN 1923A, SN 1945B, SN 1950B, SN 1957D, SN 1968L and SN 1983N) have been observed in M83.
