Caltech astronomers observe a supernova colliding with its companion star

This is a still from a simulation of a Type Ia supernova. In the simulation, a Type Ia supernova 
explodes (dark brown color). The supernova material is ejected outwards at a velocity of
about 10,000 km/s. The ejected material slams into its companion star (light blue). Such a
violent collision produces an ultraviolet pulse which is emitted from the conical hole carved out by the companion star.Type Ia supernovae, one of the most dazzling phenomena in the universe, are produced when small dense stars called white dwarfs explode with ferocious intensity. At their peak, these supernovae...
