Messier 95 (also known as M95 or NGC 3351) is a barred spiral galaxy about 38 million light years[citation needed] in the constellation Leo. It was discovered by Pierre Méchain in 1781 and cataloged by Charles Messier 4 days later.
It is a starburst galaxy, with a high rate of star formation in its core concentrated in a ring around it that houses a certain number of young, high-mass star clusters. In March 2012, a new Type II supernova was confirmed in M95, cataloged as SN 2012aw.
New observations of this object have shown stellar regeneration in action. Stellar feedback is the process of redistributing energy in the interstellar medium (the space between stars) within star-forming galaxies.
In this particular galaxy, star formation, which is taking place in the ring surrounding the galaxy’s core, is at such a violent pace that huge bubbles of hot gas can be seen being ejected. This ejected gas then contributes (both positively and negatively) to the star formation process in the galaxy.
