In a core-collapse supernova, where is the vast majority of the total energy released?

Answer

A burst of neutrinos

Over 99% of the energy from a core-collapse supernova is radiated away rapidly in a burst of neutrinos, equating to about $10^{46}$ joules, which is roughly 10% of the star’s total rest mass energy.
