Have astronomers found evidence of any other black holes in other galaxys?

Yes. In fact, it looks as if all, or most, larger galaxies have huge ("supermassive") black holes in their center. The largest black holes found so far have an estimated 20 billion solar masses.

Which theory about the universes size best matches the experimental evidence found by astronomers and physicists?
The universe is consistantly expanding
Is there evidence of volcanoes on Pluto?
At this time, astronomers have found no evidence of the presence of volcanoes on Pluto. However, they do believe the planet is going through some kind of global warming on its surface.
What do astronomers think there could be life on euopa?
Astronomers have found evidence that leads them to think that there is a saline ocean under the H2O ice that dominates the surface of Europa. A saline environment would be amenable to life.
What evidence do astronomers have that water flows on Mars?
Evidence from satellites in orbit and rovers on Mars show features like dried up riverbeds. Surveys on the surface have also found minerals that can only form in water.
What evidence do astronomers have that water once flowed on Mars?
Evidence from satellites in orbit and rovers on Mars show features like dried up riverbeds. Surveys on the surface have also found minerals that can only form in water.
How can a black hole be found?
A black hole can be found by finding a patch of space which is completely dark although there should be light there, lie a star or planet. I leave black hole tracking to astronomers and other professionals because I can't keep track of stars. :)
Does a wormhole bring you to different galaxys?
In the law of physics, wormhole can possibly exists, but no one ever found a wormhole or seen. there is no evidence that wormhole can exist. And if wormhole exists,it wont bring you to other galaxy, but you go to other universes through it and also travel in time.
Do black holes orbit the universe?
Most likely not. The best evidence of the existence of black holes has been found deep within galaxies.
Do astronomers have found all solar system objects?
no
Do the gravitational constant change with time or place?
That's a really hot question among cosmologists and astronomers. No positive evidence of a change through time has been found, but then, how would you look for it or measure it out in the universe ? ! ?
Some astronomers have found evidence for the formation of planets around other stars make a list of three characteristics these planets might need to support life?
an atmosphere, air or what the creature breathes and water
Are there really black holes in space?
Since black holes do not put out any light, we cannot see them. However, we can see the effect that they have on the area of space around them. Since black holes have extremely high gravity, they pull in surrounding material at very high speeds, causing this material to become very hot and emit X-rays. By finding this very hot material which is spiraling into black holes, astronomers can locate where some of them are. Also, astronomers study the motions of objects in space to see where there is material that might be moving as if a black hole were affecting it. So far, evidence had been found for the existence of black holes in the centers of several large galaxies, and in binary star systems (where two stars orbit each other).
