Astronomers peering billions of light-years into space have detected the largest, most extensive collection of galaxies ever registered in the early days of the universe, a "proto-supercluster" they nicknamed Hyperion after a Titan from Greek mythology.
Hyperion has a mass 1 million billion times greater than the sun. From Earth, we see how it looked billions of years ago.
"Hyperion is like 5,000 galaxies of the Milky Way," said astronomer Steffen Miefke, the chief of operations for the European Southern Observatory. The ESO operates the Very Large Telescope (VLT) in Chile, which detected Hyperion.
