Messier 82 has become a prototype for starburst galaxies, which as a class are now readily identifiable in the data from the far-infrared satellite IRAS. M82 is of particular interest because of its relative proximity, which permits the observation of individual star-related radio sources (Kronberg et al. 1985). It has, further, been recently possible to gather initial data on the temporal evolution of individual supernova remnants and other energetic objects (Kronberg and Sramek 1985). These have recently provided a first-order confirmation by direct statistics of the high rate of star formation which Rieke et al. (1980) have independently deduced by modelling to the overall radiation characteristics of M82.
