I don't think there is a galaxy called "Satan A"; at least, not as a standard name, generally accepted by astronomers. On the other hand, most larger galaxies have a supermassive black hole at its center, and it can be expected that any galaxy has several stellar black holes.
That is very likely. 1) Every larger galaxy, or most of them, have a supermassive black hole in their center. 2) Since a certain percentage of star eventually become a stellar black hole, any galaxy should have several stellar black holes,in addition to the supermassive black hole.
Let me clarify one thing... Basically, ALL galaxies, or almost all of them, have a giant black hole at their center. (If any galaxy does NOT have such a supermasive black hole, then it is likely that it had one in the past, and that it was ejected out of the galaxy.)
Not really, but in a Galaxy next to the milky way there is alot of activity and possibly a black hole.
Yes, probably many of them. We believe that there is a supermassive black hole at the center of the Milky Way galaxy; that there are probably similar suoermassive black holes at the centers of many large galaxies.
Yes. There is a supermassive black hole at the center of the galaxy and a number of stellar mass black holes through the rest of it.
Black hole has very strong gravitional force thats why if any things near from this black hole swalled this
Any star that gets too close to a black hole can be drawn into it. But most stars can orbit the center of the galaxy almost indefinitely, without such a thing happening.
No, we have not seen any evidence of a black hole in our solar system.
Black holes can technically be any where. Some scientists believe that there is a black hole in the center of our galaxy along with many other galaxies. Because black holes are so difficult to detect, they can be very dangerous.
That's really hard to say. The black hole will continue growing; in the very long term, stars in the galaxy will either fall into the black hole, or they will be catapulted out of the galaxy. Please note that all this will happen long, long after most stars stopped shining - in other words, some trillion years from now. In any case, you can't foresee for an individual star which star will be catapulted out of the galaxy, and which will fall into the black hole.
Almost every galaxy has a super massive black hole in its centre and this fact is widely accepted now days . Milky way galaxy also have a super massive black hole of its own, weighing more than 4 million times more than our sun's mass. Andromeda galaxy is our nearest neighbour having a super massive black hole in its centre weighing 114 million solar masses .
Nothing is known about any owner. You might imagine some powerful alien civilization laying claim to the black hole, but this is just wild speculation.
