Like a surveillance camera photographing the scene of a crime before it happened, the Hubble Space Telescope has an archival photo of a galaxy with a star as it appeared eight years before it exploded as a supernova. Astronomers have detailed theories about what type of stars self-destruct in supernova explosions. But this discovery has only further confounded supernova mysteries. The progenitor star belongs to a class of Luminous Blue Variables (LBVs) that are not expected to explode at such an early stage of their existence.
