Hypernova

This is a hypernova (much bigger than a well-known supernova). As a result, a colapsed hypergiant also turn into a black hole, just like a supergiant star.

Black Hole

Watch out for me! Once you're in my gravitational field, there is no turning back. Even electromagnetic radiant cannot escape from me.

Blue supergiant

What a beautiful blue and white star. It is very bright.
