M95 - Barred Spiral Galaxy in Leo


M95 is one of the main galaxies that comprise the Leo I group, which includes M96 and M105 (as well as several other fainter galaxies). It was discovered by Pierre Mechain in 1781. Charles Messier added this to the last version of his catalog that same year.

A supernova was discovered in M95 on 3/16/12.
