M82 (also known as NGC 3034 and the Cigar Galaxy) is a spiral galaxy located about 12.7 million light years away. It is a so-called starburst galaxy, as it has an exceptional rate of star formation, due to the gravitational interaction with M 81, and the rate of star formation is ten times greater than in an isolated galaxy.

M 82 is five times brighter than the Milky Way and its central region several hundred times brighter than the core of our Galaxy.

We can see on this picture the jets of ionised Hydrogen, perpendicular to the disc of the galaxy.
