Supernova is a related term of hypernova.

In astronomy terms the difference between hypernova and supernova

is that hypernova is the gravitational collapse of a massive star to form a black hole while supernova is a star which explodes, increasing its brightness to typically a billion times that of our sun, though attenuated by the great distance from our sun. Some leave only debris (Type I); others fade to invisibility as neutron stars (Type II).
