The Known Universe
The Virgo Supercluster or the Local Supercluster is a mass concentration of galaxies containing the Virgo Cluster and Local Group
, which in turn contains the Milky Way
and Andromeda galaxies. At least 100 galaxy groups and clusters are located within its diameter of 33 megaparsecs, 110 million light-years. The Virgo SC is one of about 10 million superclusters in the observable universe and is in the Pisces–Cetus Supercluster Complex, a galaxy filament.
The Virgo Supercluster is only a lobe of an even greater supercluster, Laniakea, a larger, competing referent of the term Local Supercluster centered on the Great Attractor.
The Virgo Supercluster is home to the Guardians of the Universe
whom patrol the supercluster. Though their rule is contested by many, the Guardians
patrol much of the universe
and their hands-off reign
in known by many.
