Which structure is the Virgo Cluster considered the dense, central hub of?
Answer
The Virgo Supercluster
The organizational hierarchy of the universe involves multiple layers of gravitational binding. The Virgo Cluster, despite its massive size, is itself a component of a larger structure known as the Virgo Supercluster. The Cluster functions as the dense, central hub of this Supercluster. It is important to differentiate this relationship from the Supercluster itself, which is the much larger extended structure encompassing the Cluster, the Local Group (where the Milky Way resides), and numerous other smaller groups and clusters.
