A black hole cannot be observed directly. It cannot be "seen" as we understand the term in its basic form. But we can use a telescope to "guess" that a black hole may be in a certain location by the effects of the black hole.

The presence of a black hole can be deduced from the way nearby stars move around it, or it may be "seen" by what is called gravitational lensing. The latter is a phenomenon whereby light from sources "behind" the black hole is "bent" around the black hole. If a black hole is close enough, the generation of X-rays at the event horizon would allow it to be detected, but don't count on anyone finding one in this manner. Use the link below to learn more and see a short motion graffic of gravitational lensing.

How can you say there is a black hole?

You can't see the black hole but you can see its inflence on its environment. (You can see matter that is sucked into the black hole)

Can we see black holes?

You can't see a black hole.


Can you see a black hole when you are on eath?

You cannot see a black hole when you are on Earth, unless a black hole were to absorb Earth, which even then, you would see it in a split-second before it would engulf you


What is black that you can't see in it?

A black hole


Is there anysites you couldd see the hole?

If you are talking about a black hole the answere is no. Not even light can ascape the force of gravity of a black hole, therefore you can't see the hole itself.


is a black hole a hole or not a hole?

It is a hole because it brings things inside of it, but it's all black so you can't see anything.


Can you see a video of the black hole in space?

While there are no direct videos of black holes in space, astronomers have used telescopes to capture images of the matter surrounding black holes, known as the black hole's accretion disk. These images help us study black holes and their properties, but we cannot directly see the black hole itself due to its nature of trapping light.


How do you see a black hole?

Technically, you can't "see" a black hole, since no light can escape from it, therefore the light cannot reach your eyes.


Where is the black hole that you get the space sharks in poptropica?

To get to the black hole you have to go to straight until the little square says "approaching black hole". Then when you see that you just go straight and you'll see it, but don't get sucked in!


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.


If nothing can escape a black hole in outer space how can you see photos of a black hole?

The answer is, you cannot see photos of a black hole. You are quite right; not even light can escape a black hole's incredible gravity, so all black holes are completely invisible. It is possible, however, to see long trails of matter that is being pulled into a black hole. The way we detect black holes from earth, however, is by picking up the gamma rays that they emit.
