Black holes do not emit light, so black holes can not be seen this way. But black holes emit X-rays, but stars are not hot enough to emit X-rays. When black holes suck up stars, energy goes to the black hole, and come out as X-rays.
no. there are no black holes in our solar system.
Probably stellar mass black holes
The most massive stars will die as black holes.
Most black holes form when massive stars exhaust their fuel and their cores collapse. There are also supermassive black holes at the centers of most galaxies. Scientists are not sure how supermassive black holes form.
Dead stars are not necessarily black holes. Dead stars can become white dwarfs, neutron stars, or black holes depending on their mass. Only the most massive dead stars can collapse further to become black holes if they exceed the Chandrasekhar limit, around 1.4 times the mass of the Sun.
actually black holes are the masters of gravity has the most gravity ever
The most massive stars become black holes.
Most black holes were once the cores of very large stars that collapsed.
Unknown - As they can't easily be detected, and most of them are expected to have been formed upon the onset of the Big Bang. Astronomers estimate that in our region of the Universe, there are some 100 billion supermassive black holes. But this does not account for the lesser size black holes, of which there is estimate to be a much larger number.
Most black holes are believed to form when very massive stars die.
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.
Most or all galaxies appear to have supermassive black holes at their centers and probably have stellar mass black holes scattered throughout.
