What is the difference between a Black Hole and a Supernova?

Answer 1

Supernova is formed during death of a star ,during which enormous amount of energy is given out.

Whereas a black hole can be thought to be an object having large mass and very small radius , so that it's escape velocity is greater than that of light ,that is even light cannot escape from it's gravitational attraction force.

Answer 2

A black hole is what remains after the supernova is finished exploding.

When a supernova explodes, it generates such intense heat and pressure that atoms that cannot normally fuse together, like carbon and iron, ARE fused together, creating all of the heavy elements such as lead or gold or uranium. The explosion is so enormous that as it is creating these heavy elements, the supernova is also blasting the star apart and throwing a good percentage of itself back into space.

The core of the star is crushed beyond measurement into the "ultimate" density of a black hole, while the outer layers are thrown out into space - where they can help to form new solar systems like our own. Because our bodies contain elements like iron and magnesium, we KNOW that we contain star-stuff; that's the only way iron could ever form, in the explosion of a supernova.

Answer 3

A black hole is a region in space where gravity is so strong that nothing, not even light, can escape. It forms after a massive star collapses under its own gravity. A supernova, on the other hand, is a massive explosion that occurs when a star reaches the end of its life cycle and suddenly releases a tremendous amount of energy.

Answer 4

they are quite opposite, a vacuum is a lack of any matter and a black hole is so much matter with such a great gravitational pull that light can't escape
