NEW SUPER CLUSTER OF GALAXIES

Using data from the eROSiTA x-ray telescope astronomers have detected a previously unknown supercluster of galaxies. Cosmic structures evolve hierarchically from high density peaks in the primordial density field and form galaxies, galaxy groups, and cluster of galaxies under the action of gravity. In the complex large-scale structure formation scenario, these galaxies, groups, and clusters are connected to each other via filamentary structures called the cosmic web and form large superclusters. The newly-discovered supercluster resides approximately 4 billion light-years away from Earth. It consists of a chain of eight galaxy clusters.This supercluster stretches for about 1.5 degrees from the north to the south on the plane of the sky, or 88 million light-years considering the physical distance between the furthest clusters in the chain.
