Not really "a" black hole - many black holes. It is currently believed that all, or most, galaxies have a huge black hole at its center. Any galaxy should also have lots of smaller black holes - so-called "stellar" black holes, because they have approximately the mass of a star (larger stars can become black holes).

Which objects contain super massive black holes?

What might the center of a rotating spiral galaxy contain?

Are there black holes in our galaxy?
Yes. Our galaxy has a supermassive black hole at its center and likely millions of stellar mass black holes scattered throughout.
How many black holes were in this galixy?
Black holes are a bit hard to detect, so I am pretty sure that not all black holes in this galaxy are known - and I suspect there is not even a decent estimate. But you can expect there to be several.
Are there any black holes in your galaxy?
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.
Are black holes very common?
Yes, Black Holes are very common in our galaxy and general.
Does every galaxy have a black hole at its center?
Not every galaxy has a black hole at its center. While many galaxies do have supermassive black holes at their centers, there are also galaxies that do not have black holes.
Do we believe there are black holes in our galaxy?

What are young galaxy stars that have giant black holes at the center?
It's not "galaxy stars", but galaxies, that have the black holes at their center.All, or most, galaxies have a giant black hole at their center.
Where have black holes been found?
Scientists predict that there are over one million black holes in our galaxy
Do all galaxies have black holes?
Not all galaxies have black holes. While many galaxies, including our own Milky Way, have supermassive black holes at their centers, there are also galaxies that do not have black holes. The presence of a black hole in a galaxy depends on various factors such as the size and age of the galaxy.
What if a supernova was caused by the black hole at the center of the galaxy?
Black holes do not create supernovae. Black holes are created from a supernovae.
