M82 is located in Ursa Major near M81. It is about 12 million light years away and is about fie times more luminous than the Milky Way. It is undergoing a very high rate of star formation, so high that it will consume most its star forming gas in less time than the age of the galaxy. Apparently, gravitational tidal forces from its larger neighbour M81 have deformed the galaxy and caused the massive star formation. The image was captured in Tucson in March 2015 - 22 10-minute subs.
