M82 has an angular size of 9 x 4 arcminutes and has very high surface brightness. ... The high surface brightness is due to the very high star formation rate currently operative in M82. The interaction of this star formation pattern and the peculiar distribution of dust in M82 gives rise to its peculiar appearance and its misnomer label as an "exploding galaxy". The high star formation fuels vigorous hydrodynamic winds in the galaxy which can eject material to distances beyond the galaxy. ...
