Animation of Supernova Producing a Black Hole

How a black hole may have been formed? The video from NASA which shows the collapse of a massive star after it has exhausted its fuel, is amazing and very impressive.
A flash of light from a shock breaking through the surface of the star is then shown, followed by a powerful supernova explosion. The view then zooms into the center of the explosion.

This is one of the major step towards unfolding deep and dark secrets in a black hole!!!
