  What it is

M82 is an irregular Galaxy which is believed to have been stirred up by a recent pass of the large spiral galxy M81 which is some 0.5 degrees to the south. This doesn't fully explain the source of the gigantic streams of red-glowing outwardly expanding gas, However. recent evidence indicates that this gas is being driven out by the combined emerging particle winds of many stars, together creating a galactic "superwind" of ionized hydrogen gas. These show up as delicate filaments of red gas. The filaments extend for over 10,000 lights. M82 is approx 12 million light-years away and it is the brightest galaxy in the sky in infrared light.
