Black holes might be seen by their Hawking radiation, but that radiation is expected to be extremely weak. It is more likely that a black hole would be seen:
- By observing the movement of other objects around the black hole.
- By gravitational lensing. All of these depend on the gravity of the black hole.

Before reaching the event horizon, the tremendous acceleration will produce electromagnetic waves (X-rays, for example).

In what constellations are there black holes?
None. Black holes are completely black, making them invisible, so it would be pointless to put something you can't see in a constellation.
Are black holes invisable?
Yes and no. It is rather hard to explain, because black holes are so dark and black that no living creature can see them, which in a sense makes them invisible, but you can also see where a black hole is because it sucks in light, too, so that would also, in a sense make it visible, but the my main answer would be, no black holes are not invisible.
Why cant you see black holes?
Due to light being unable to escape the black hole, we cann't see it! It's like trying to see in a dark room with a flashlight, that has dead batteries. You cann't see the light because their is none to reflect.
How can we see black holes?
You can't see a black hole.
Can we see black holes?
You can't see a black hole.
Why cant you see black holes from earth?
Black holes emit so very little radiation they are hard to see. Many black holes lie at the center of galaxies and there they are hidden by stars and dust.
What comes after black holes?
After the black hole dies out, (see When do black holes die and/or How does a black hole get smaller) it will become just a vacuum.
What do black holes emit that could allow them to be detected from the earth?
Black holes does emit radiation, but they cannot be detected from earth. We use gravitational lensing to "see" the black holes.
Why black holes are black for kids?
Black holes are blavk because their gracity is so strong that light cannot escape for us to see.
Does black holes elongate matter that is sucked in?
That's what the mathematical theories suggest would happen. We have never observed this, and with any luck we never will be close enough to see this. Black holes are dangerous places.
If you can't see black holes would you be able to see white holes?
No, you wouldn't. If the white hole spoken of in the question is the one associated with the black hole, it is a term applied to the reversal of time within the black hole. How can you see time reverse itself? Certainly you would not be able to see it from outside the black hole, and there are few volunteers for a trip in. Also, no one who goes in ever comes back, or even sends messages out. We won't be seeing white holes any time soon, if at all.
What is a great model for black holes?
