We know that our Local Group, which contains Milky Way, Andromeda, the Triangulum Galaxy, and several dwarf galaxies.
This Local group is part of a much larger colony containing over a hundred galaxy groups like ours, called the Virgo Supercluster, and it extends over an area of more than 110 million light years.
But the cluster network doesn't end here.
Scientists at the University of Hawaii revealed that the Virgo Supercluster is just one component of an even greater network of a galactic supercluster, Laniakea. The Hawaiian word for "immense heaven."
The Laniakea Supercluster extends over half a billion lightyears across space.
Laniakea consists of four main galaxy superclusters;
Virgo Supercluster, the Hydra Centaurus Supercluster, the Pavo-Indus Supercluster, and the Southern Supercluster.
Despite their enormous cosmic distances from each other, they interlink to create a plethora of flows across space.
Because the Laniakea Supercluster is so large, it is not dense enough to be gravitationally bound
Instead of coming together, gets caught up in the Hubble Flow, (the motion of galaxies due to the expansion of the Universe,) and disperses the supercluster.
