No, Betelgeuse still hasn’t exploded, but other things have gone boom in the past and today we look at the results of one of the brightest supernovae, SN2006gy, and the oldest supernovae that went into forming the metal poor ancient star J0815+4729. Understanding these objects takes powerful computers, and we also discuss how new materials science points at how a new alloy, when super-cooled, may be a needed breakthrough for quantum computing.
