NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) is unraveling the mystery of how stars go supernova by mapping the remnants of radioactive material left in the wake of a supernova. The findings go against previous theories to create a more chaotic view of the conditions prevailing directly before a star explodes.
