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.
For the most part, we can't see individual stars in other galaxies (with one notable exception), so obviously detecting planets is out of the question. (The exception is supernovae, stars that are in the process of exploding.)
The center is crowded with stars, and the number of stars decreases farther out.

The concentration of stars is typically more centrally located in elliptical galaxies compared to spiral galaxies. Elliptical galaxies have a more concentrated spheroidal shape with stars distributed densely in the center, while spiral galaxies have a more spread-out disk structure with stars distributed along spiral arms.
The brightness of normal galaxies is mainly due to stars; quasars are believed to get most of their energy output from the black hole at their center.
they all contain billions of stars that orbit the center of the galaxy. all galaxies are also moving very slow.
Stars travel in various ways. On the largest scale, the universe expands, and stars move away from each other. On smaller scales, stars are most often part of galaxies and they orbit the center of the galaxy, while the galaxies themselves often are in orbit around a center of gravity of a galactic cluster.
Yes, it does, unless the light is obscured by other things like dust clouds, galaxies or bigger stars.
All galaxies are massive clusters of stars scattered across the universe. Many galaxies take the same form, for instance, spiral and elliptical galaxies. Some galaxies also have a black hole in their center.
No stars are actually a galaxy. All stars are stars and all galaxies are galaxies. Stars are found in galaxies. Some galaxies look like tiny dots in our night sky, so might look like a star, but they are not stars; they are galaxies.
