a galaxies does not move that is why there are many stars
Not all galaxies have black holes in their centers, but many large galaxies, including our own Milky Way, are believed to have supermassive black holes at their centers.
Probably, but impossible to tell as we are only just seeing planets within our own galaxy.
Galaxies vary a lot in size, from dwarf galaxies that have a few hundred million stars, to huge galaxies with a hundred trillion stars. (That's a ratio of about 1 to a million.)Our own galaxy has somewhere between 200 and 400 billion stars. Actually, most galaxies are quite a bit smaller than our own galaxy, since dwarf galaxies occur in larger numbers.
Yes its called the Local Cluster or Local Group, we have many minor Globular or Cluster Galaxies orbiting our own.
Say about 100 billion in our own galaxy, then about 100 billion galaxies.
Our galaxy, the Milky Way, is itself a galaxy, made up of approx. 200 billion stars. There are no other galaxies within our own.
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.
Galaxies are made partly of stars, which produce light. So, in that sense, yes.
Our own galaxy, the Milky Way, and our closest neighboring galaxy, Andromeda, are both spiral galaxies.
Galaxy clusters typically have anywhere from 50 to 1,000 galaxies.
