Supernova 1993J. Computer illustration of supernova 1993J,an exploding star in the galaxy M81. This supernova originated in a double-star system where one member was a massive star that exploded after siphoning most of its hydrogen envelope to its companion star. After two decades,astronomers have at last identified the blue helium-burning companion star at the centre of the expanding nebula of debris from the supernova.
