Black holes are invisible but the matter falling in makes friction and heats up which glows and gives of heat,x rays,etc.
Most black holes look like galaxies, you know, the usual swirl with the strange black dot in the middle. Some black holes look like a simple black dot, floating in space.
A Black Hole model is considered more or less like that for stellar mass, with the exception that its mass density is such that its force of gravitational acceleration toward its mass is faster than the speed of light. This immense gravitational attraction not only pulls in other mass objects, but condenses and converts the attracted mass in energy. To describe this condition, I would refer to the state of the universe immediately after the Big Bang event; i.e. this condition provided for a hot dense state of plasma. Consequently, there is no real mass within a black hole; rather all attracted mass is converted to energy. If fact our best evidence ever was provided with the observations of the three-telescope interferometry. The astrophysicists described their findings as a ring of hot dust that marks the transition from a more-distant mixture of gas and dust in a toroidal (doughnut-shaped) structure, to a gaseous disk closer to the black hole. The dusty part, he said, is interesting because it dominates the infrared emission of active galactic nuclei and can be easily observed. Once pulled in beyond a Black Hole's event horizon, the only escape is in the form of relativistic jets emitted along the poles, which carry away much of the energy. Among Stephen William Hawking's significant scientific works have been a collaboration with Roger Penrose on gravitational singularities theorems in the framework of general relativity, and the theoretical prediction that black holes emit radiation, often called Hawking radiation.
Depends on what's near it - they give off no light themselves, so it has to come from the environment around it.
A bit red. And it looks like mario.
The two parts of a black hole are the event horizon and the singularity. The event horizon is the "surface" of the black hole, and is imaginary. The event horizon's appearance is caused by the bending of light. The singularity is a point of space where everything that gets sucked in is crushed to about the size of an atom.
The material sucked in to a black hole becomes part of the black hole - that is, a black hole crushes matter to an nearly no size, at all.
No. A black hole will remain a black hole. A neutron star is a remnant of a star not massive enough to become a black hole.
A black hole is a type of star with excessive gravity. Here are some sentences.The star was sucked into the black hole close by.A black hole will even absorb light.The scientist is studying a black hole.
Neptune does not have a black hole

The collapses star gets squeezed by collapses gas and turns into a black hole.
A Schwarzschild black hole is a non-rotating black hole. The Kerr black hole is a rotating black hole. Since the latter is more complicated to describe, it was developed much later.A Schwarzschild black hole is a non-rotating black hole. The Kerr black hole is a rotating black hole.

A black hole originated as a star, that is, the star converted to a black hole.

If you fall into a black hole, you'll go into the black hole and nowhere else.
probs black hole
Black hole is a location in space that possesses so much gravity, nothing can escape from its pull. Yes, Super massive black hole is the largest black hole.
No. A black hole will remain a black hole. A neutron star is a remnant of a star not massive enough to become a black hole.
We know nothing about the conditions within a black hole, but it seems unlikely that a black hole could exist within a black hole, or even if this concept would have any meaning at all.
Yes. Intermediate-mass blackhole is a medium size black hole. Scientists have found stellar black holes and supermassive black holes but there is no prove that Intermediate-mass black type of black holes exist. My opinion is that they do exist because when a black hole is becoming a black hole supermassiveblack hole it will need to go though this stage of intermediate-mass black hole.
