Abstract

We present the discovery of a red supergiant star that exploded as supernova 2003gd in the nearby spiral galaxy M74. The Hubble Space Telescope (HST) and the Gemini Telescope imaged this galaxy 6 to 9 months before the supernova explosion, and subsequent HST images confirm the positional coincidence of the supernova with a single resolved star that is a red supergiant of 8/sub -2//sup +4/ solar masses. This confirms both Stellar evolution models and supernova theories predicting that cool red supergiants are the immediate progenitor stars of Type II-plateau supernovae.
