What is a supercluster of galaxies?
CosmologyLarge-Scale Structure
Quick Answer
A supercluster is a very large grouping of galaxy clusters and groups. It is one of the biggest structures recognized in the observable Universe.
The Full Story
Superclusters are enormous associations of galaxy groups and clusters, linked by filaments in the cosmic web. They are not always fully gravitationally bound as single objects, but they mark some of the densest regions of the Universe. The Local Group belongs to the larger Virgo Supercluster region, which itself is part of a more complex structure now often discussed in terms of the Laniakea region. Superclusters help astronomers study how matter is distributed on the largest scales.
