Supernova explosions are the most energetic events observed in our Galaxy. The 1051ergs of thermal energy they release is one of the primary energy sources for the interstellar medium. They are responsible for dispersion of all atomic species heavier than He. They also leave behind the exotica of the stellar menagerie, neutron stars and black holes. The explosive release of such a large amount of thermal energy leads to the heating via shock waves of both the supernova ejecta and the surrounding interstellar medium to X-ray emitting temperatures for tens of thousand of years after the explosion. X-ray imaging and spectroscopic studies of supernovae and their remnants provide insight into the nature of the progenitor, the symmetry of the explosion, the degree of mixing of ejecta, the structure of the ambient interstellar medium, and the presence of particle acceleration by a pulsar or via shock acceleration. The author presents an up to date discussion of X-ray observations.
