A supernova is an enormous explosion that marks the death of a massive star. A black hole is a super-dense remnant of a supernova; an object around which gravity is so intense that even light cannot escape. -Science In Action 9 Textbook
the gravitational field of a black hole is so vast that even light can't escape form it and in the case of a ghost, I think ghosts are kind of negative energy , so when a ghost goes near to the black hole then deadman will die again
Supernova explosions are believed to generally result in a black hole, as the core of the star is collapsed into an unimaginably dense point mass. One can't really say that a black hole is any kind of star. Less powerful nova explosions probably result in pulsars or neutron stars.
Black holes emit a form of energy called Hawking radiation, which consists of particles being emitted from the black hole's event horizon. This radiation causes the black hole to slowly lose mass over time.

There are two types of stars: a small kind, like our Sun, and larger stars. Smaller stars live out long lives, then expand into Red Giants, then puff out their edges, creating a nebula and a white dwarf star. For larger stars, their life is much smaller and more violent ending. When a larger star dies, it expands into a Red Supergiant, then explodes in what's known as a Supernova. For a Supergiant whose core mass isn't too large, it turns into a neutron star. If the core's mass if greater, the gravity is so great, that it collapses in on itself, creating a black hole that will collapse itself by its own gravity and will go on collapsing till it becomes a black hole.
Only stars that are much more massive than our sun can become a black hole. When the star dies, it explodes (called a supernova) and then gravitational collapse helps it to form a black hole.
The black hole....and not Oprah kind, the space kind.

technically, we do not know whether black holes are real. theoretically, they are completely possible. scientist believe that they have seen on but are not sure. if real, the largest one originate from larger stars
very hot
A degenerate star or stellar remnant.
Since light cannot escape a black hole it is essentially invisible. Just a literal black hole in space. Fortunately, due to the extreme gravity of the singularity, light is bent (Gravitational lensing) around the outskirts of a black hole which causes a visual distortion of light.Think of a piece of metal with a bullet hole. Around the hole the metal is warped, distorted and pressed inward. That is how you would see a black hole except it would be much more difficult to see. If a black hole eclipsed a star close enough, you would see a round black emptiness surrounded by light. The hole itself is absorbing every bit of light from the star but some light is orbiting *around* the black hole as it's being sucked in causing a kind of halo. This is essentially how we look for black holes.

Not at all. The Milky Way is simply a galaxy: a collection of stuff (mostly stars, with some planets and even some black holes) orbiting around each other. A black hole is a star that collapsed upon itself at the end of its life, and has a very high gravitational pull close to its "surface" (the event horizon).
when Dwarf Stars run out of hydrogen they form Red Giant stars, then from that they become White dwarf stars when the outer layers shed, forming a planetary nebula.when giant stars or supergiant stars run out of hydrogen they form red supergiant stars
