a black hole is formed when a star dies (it explodes). sometimes it can also form a nebulae
A dead star. The dead star's smashed atoms come together, and are crushed again. This births a black hole
No, there are many black holes in space. They reside throughout the universe and come in different sizes, ranging from stellar-mass black holes to supermassive black holes found at the centers of galaxies.
No. A black hole may be the remnant of the core of what was once a blue star, but the black hole itself is as black as anything can possibly be.
No, based on our current understanding of physics, a spacecraft would not survive traveling through a black hole. The intense gravitational forces would stretch and compress the spacecraft to the point of destruction.
A black hole contains a large amount of matter, compressed in an incredibly small space.
No. Once something enters a black hole it can never come out.
No, a black hole is not actually a hole in space. It is a region in space where gravity is so strong that nothing, not even light, can escape from it.
the black hole is a matter in outer space that is made by the force of gravity

Yes, a black hole could travel through space.
Obvisouly it is not a black hole! :)
Within the so-called event horizon, space and time around the black hole are distored in such a way that the only way a ray of light (for example) can move is closer towards the black hole's center.
Yes
Black holes actually come in different masses, and therefore sizes.
no because it would destroy the space if it went in to a black hole
The black hole itself cannot be seen, however, its pulling effects of the surrounding area can be seen.
No non-fictional astronomical body know as black circle. If the question is meant to employ the term 'black hole' in space, what a black hole does is to exist.
