COMMENTS: M82 is a starburst galaxy resulting from a near-miss encounter with the nearby galaxy, M81 a few hundred million years or so ago. The gravitational encounter set off an explosive burst of new star formation sending wisps and tendrils of hot gas and relativistic particles spewing from its poles for tens of thousands of light-years. A large black hole in its center surrounded by huge numbers of stars going supernova are thought to produce the relativistic hot out gassing. Eventually, this burst of intense activity will settle down when much of the compressed gas and dust has thinned.
