They are simply called "galaxies which are part of a cluster".
They are still called galaxies.
Nebulae or star clusters within the Milky Way Galaxy.
Yes. Galaxy clusters are clusters of galaxies and therefore larger than individual galaxies. Superclusters are clusters of galaxy clusters and so are larger then galaxy clusters. Filaments are collections of superclusters and are the largest known structures in the universe.
An irregular galaxy is a galaxy that doesn't have a specific shape like a pinwheel or an elliptical galaxy.
The basic idea of Hubble's Law is that galaxies (or galaxy clusters) that are farther away move away from us faster than those that are closer to us.The most distant galaxy yet found is a protogalaxy with the designation UDFj-39546284, with a redshift z = 11.9, about 13.42 billion light-years distant from the Milky Way.In case you are asking for the most distant CLUSTER of galaxies, and not the most distant astronomical galaxy, the answer would be the cluster (or protocluster, science is not yet sure about the nature of this structure) which denomination is BoRG-58 , with a redshift z≅8, and about 12 billion light-years distant from us.
No. It is a disk-shaped galaxy, like a pinwheel, with several curved radial arms and a large mass at the center. The closest thing to a "clump" of stars are the so-called "globular clusters" which are more spherical in organization than other common galaxies.
Most galaxies, even our own, are found in groups or clusters. For example, the Local Group contains several galaxies including the Milky Way, Andromeda, and the Magellanic clouds.
In spiral arms of spiral galaxies
near giant elliptical galaxies.
Galaxies
Galaxies.
They are located only in the ARMS of galaxies, not outside.
Clusters
Quasars are related to supermassive black holes in the center of galaxies.
A supercluster.
galaxies are in every direction in space there in clusters and super clusters
galaxies
Because they have the most mass
