For most purposes, no, black holes themselves are not visible. Black holes absorb everything near them, including light. Light needs to originate from an object or strike an object and reflect from it and to your eyes in order for you to see it. Light that enters a black hole can never leave. Since black holes do not emit light or any form of electromagnetic radiation, it is impossible for astronomers to observe them directly. However, matter falling into a black hole can become superheated and emit light and x-rays before falling past the point from which nothing can return. We can detect this radiation.
Theoretically, you could also see the event horizon of a black hole if you got close enough; it would appear as a completely black sphere against a background of stars. The light from stars behind the black hole would be highly distorted, as can be seen in the image above.
What else can I help you with?
What is a good black hole candidate?
A good black hole candidate is typically a region in space where high-energy astrophysical phenomena are observed, such as X-ray emissions or gravitational lensing effects, without a visible source of light. This can indicate the presence of a compact and extremely massive object that is likely a black hole.
What does it look like to go near a black hole?
You might think it would look amazing and scary! But... no. Black holes suck in light so it is not visible.
Which is the biggest known black hole in the universe?
The supermassive black hole that hosts the galaxy NGC 1277, in the constellation Perseus, is currently the largest black hole in our visible universe with a mass equivalent to 17 billion suns. In 2012, astronomers have discovered this small galaxy about 250 million light-years from Earth.
What would a black hole look like from earth?
This depends on so many factors, including the distance of the black hole, the size of the black hole, and whether or not it is actively "consuming" nearby mass. Generally speaking, if a black hole is taking in mass, as the matter falls into the black hole it can form an accretion disk. When this occurs, the matter becomes heated by friction, resulting in the release of visible light, causing the accretion disk to become quite bright. If, however, a black hole isn't taking in matter, it will not be visible.Black holes cannot be directly observed, regardless of whether or not they are actively taking in matter. Instead, they are determined indirectly by observing their gravitational interactions with their surroundings.
What exerts such a gravitational pull that no electromagnetic radiation can escape?
A black hole exerts such a strong gravitational pull that not even electromagnetic radiation, including visible light, can escape its grasp. The intense gravitational force of a black hole warps spacetime to create a region from which nothing, not even light, can escape.
Could you see a black hole if you were on the moon?
No. The gravitational field of a black hole is so great that electromagnetic radiation in the visible spectrum does not escape from them. Therefore, you couldn't directly see a black hole regardless of where you were in the universe.

What is the difference between a Scchwarzschild and a Kerr 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.

How can you see a black hole?
You cannot see a black hole directly. Which is probably just as well, since if you were close enough to see it, you would already be dead and fried by the radiation surrounding it. We can DETECT a black hole by that very radiation - the radiation generated as matter is accelerated to nearly the speed of light as it falls into the black hole. In fact, the first black hole ever identified, Cygus X-1, was detected by being a bright X-ray source with no visible star to account for it.
What does the black hole do to the star?
A black hole originated as a star, that is, the star converted to a black hole.
How do scientists know black holes exist if these objects don't emit visible light?
They don't directly emit light, but anything falling into them will emit strong electromagnetic radiation - due to the acceleration of the matter falling into the black hole. Also, the black hole attracts all matter near it.
13 Stars often occur in pairs revolving around their common center of mass If one of the stars is a black hole it is visible Explain how the existence of such a black hole might be inferred from?
Einstein's theory of the fabric of space that each planet has its own gravity that makes an indention the fabric of space depending on the amount of gravity, well a black hole is an infinite indention.
Where will you go in a black hole it?
If you fall into a black hole, you'll go into the black hole and nowhere else.
