M82 is the prototypical starburst galaxy and its close proximity make it an ideal target for study. The central kpc
region of this galaxy is heavily obscured containing large quantities of gas and dust. These large quantities of gas and dust are
the fuel for the ongoing star-formation in the region which can be seen to manifest itself in the numerous >50 compact radio
sources which have been detected. These sources are a mixture of radio supernovae, supernova remnants and HII regions all of
which can be spatially resolved by radio studies allowing both their structure, and by long term monitoring their structural
evolution to be studied. In this talk I will give an overview of our current understanding of the central M82 starburst as
derived from deepest and highest angular resolution radio studies of this galaxy to be so far made
