What is a Globular Cluster?

To achieve the spatial distribution of stars in a Globular Cluster, as has been observed, a black hole fraction of 22% is necessary.

Globular clusters are fascinating astronomical objects composed of densely packed groups of stars. They are distinct from open clusters, which typically contain a few hundred stars, as globular clusters can host hundreds of thousands to millions of stars.
