Supernova 3C58, first observed in the year 1181 AD by Chinese and Japanese astronomers, was imaged by the Chandra telescope in X-ray emissions. Type Ia supernovae are the "standard candles" astrophysicists use to chart distance in the Universe. But are these dazzling exploding stars truly all the same. To answer this, scientists must first understand what causes stars to explode and become supernovae. Recently, a unique collaborative project between the California Institute of Technology (Caltech) and the Weizmann Institute of Science provided a rare glimpse of the process.
