A spherical cluster.
Global Cluster
Star cluster or Stellar cluster.
I think you are describing a "globular cluster", which are associated with older stars by most astronomers.
A tight group of stars that resembles a snowball and can contain up to 1 million stars is known as a globular cluster. These clusters are densely packed spherical collections of older stars, typically found in the halos of galaxies. Globular clusters can be quite ancient, often containing stars that are several billion years old. Their compact nature and high stellar density distinguish them from open clusters, which are looser and younger.
a group of the stars
A collective noun for a group of stars is a cluster of stars (small group) and a galaxy of stars (large group).
That is a globular cluster. These clusters are spherical collections of stars that orbit around the center of a galaxy in its halo. They are typically made up of thousands to millions of stars that are much older than the stars found in the disk of the galaxy.
