Messier 95 (also known as M95 or NGC 3351) is a barred spiral galaxy about 38 million light-years away in the constellation Leo. In the Catalogue of Named Galaxies, it is called Calopis Leonis, or the beautiful-eyed galaxy. It was discovered by Pierre Méchain in 1781, and catalogued by Charles Messier four days later. At an apparent magnitude of 11.4, it is the faintest of the Messier objects. On 16 March 2012, a supernova was discovered in M95.
Nucleus
The center of the galaxy contains a ring-shaped circumnuclear star-forming region with a diameter of approximately 2000 ly (600 pc).
Galaxy group information
M95 is one of several galaxies within the M96 Group, a group of galaxies in the constellation Leo. The group also includes the Messier objects M96 and M105.
Supernova
A Type II supernova, designated as SN 2012aw, was discovered in M95 on 16 March 2012.
