supercluster
  • A cluster of clusters of galaxies. Superclusters are the largest objects so far described apart from the universe itself. An example is a supercluster centred on the Virgo cluster of galaxies, which is of special interest because our own galaxy, and the other members of its local group, are members of this supercluster. Superclusters typically have a sheet or filament shape when mapped in three dimensions.
