Detonating Supernova (IMAGE) University of Chicago Caption A snapshot of a Type Ia supernova simulation taken very shortly after the moment of detonation. The energy released during the detonation is equivalent to 1,027 hydrogen bombs, each equivalent to 100 megatons of TNT. This tremendous energy release makes Type Ia supernovae some of the most intrinsically luminous explosions in the universe, and therefore useful as distance indicators for cosmology.
