Also known as the starburst galaxy, M82 lies about 12 million light years away. M82's unique bipolar outflow (or 'superwind') appears to be fueled by the energy injected by supernovae that occur about once every ten years. In April 2010, radio astronomers working at the Jodrell Bank Observatory of the University of Manchester reported an unknown object in M82. The object has started sending out radio waves, and the emission does not look like anything seen anywhere in the universe before.
