This is a full frame presentation of M82 after the appearance of SN2014J. The jets of red hydrogen gas projecting out of the plane of the galaxy on each side are thought to be largely driven out by the frequent supernovae that occur within M82; they appear at a rate of about 1 per decade. SN2014J has a reddish-orange tint, due to scattering of light by M82's dust lanes interposed between us and the supernova.
