This rare galaxy cluster, which is located 10 billion light travel distance years from Earth, has a mass of almost 500 trillion Suns.

This object has important implications for understanding how these mega-structures formed and evolved early in the Universe.

The location of this “core” of gas suggests that the cluster had a collision or interaction with another massive system of galaxies, perhaps within about the last 500 million years.

This cooling rate can be slowed by outbursts from a supermassive black hole in the center of the cluster.

Despite the high mass and rapid evolution of this cluster, its existence does not pose a threat to the standard model of cosmology.
