Supernovae and Blackholes

What are they?

Supernovas are very huge explosions caused by a star dying. Black holes are what appear after a supernova of reasonable size. They have an extremely intense amount of gravitational force that is so powerful, absolutely nothing can get through it. Not even light.

How do they happen?

The star's core runs out of hydrogen, and nuclear fusion can't balance the pull of gravity, so the outward pressure goes away and gravity becomes the strongest force. The star's core collapses, the temperature sky rockets, and helium produces energy and increases the size of the planet, making it red. The explosion burns up everything and giant shockwaves blast the star's outer layer.

More Information About Supernovae

At its peak brightness, it can be brighter than an entire galaxy! The explosion shoots up huge clouds of gas and dust at up to ten percent the speed of light.

Different Types of Supernovae

Thermonuclear Supernovae - A white dwarf explosion is the biggest of all. When it increases to 1.4 times the size of the sun, the supernova process begins. It usually happens when the white dwarf gets too close to its nearby neighbor and starts pulling things from it. The size of it increases and the supernova happens.
