The Virgo Supercluster (aka Virgo SC,
Local Supercluster, LSC, or LS)
is a supercluster
including the Virgo Cluster and the Local Group,
and other galaxy clusters (and groups) such as the Fornax Cluster.
It has now been declared to be a portion of a larger
supercluster, which has been named Laniakea Supercluster.
(With this new nomenclature, the term Local Supercluster logically
applies to Laniakea, but the term is still often used for the Virgo
supercluster, thus is ambiguous.)
