Did this Supernova Explode Twice?
Type 1a supernovae occur when a white dwarf consumes material from a binary partner until it has accumulated so much nuclear fuel that it detonates in a single flash, completely vaporizing. These supernovae follow a predictable light curve, flashing brightly and fading over the coming days and weeks. A newly discovered supernova didn't follow the usual pattern, and astronomers think this might be a rare "double detonation" supernova, where the star has been feeding on a helium star and not a more common hydrogen fuel.
