A supernova is the explosion of a red super giant which happens when it has run out of Helium to fuse.

About Supernovae

When a massive star runs out of Helium to fuse the core collapses rapidly. Eventually the elements collide with one another and rebound outwards into an explosion known as a supernova which can be brighter than all the other stars in a galaxy put together.
The supernova will leave behind a core which is either a neutron star or a black hole depending on its mass. The greater mass becomes a black hole.
