black holes can be formed in a supernova explosion if the mass of the star is largeenoughusually they are created when a massive and dense star like a neutron star collapses
Black holes are round because they are formed from dead stars and white holes. As you can guess a star is a sphere and that is why black holes are round.
Black holes are the result of the gravitational collapse of a large star.

Supernova happens when a star that is at least 3 times larger than our sun dies, it will be crush by its own gravity. Then boom, supernova. Then the star acts like a sponge, it will get bigger. That star is not a star anymore, it is a black hole.
The most massive stars will die as black holes.
Black holes are the result of a large star that has collapsed.
Neutron stars and black holes.
Except for supemassive black holes, no. Most black holes have about the same mass as a star, but the event horizon is only a few miles across.
The Black Hole destroys the planet and/or star by producing a picture of Michael Jackson
Usually at the center of a galaxy or where a large star has exploded.
Theoretically they can be as large as a small star or as large as a galaxy
