May 1, 2023. Early-Universe Protocluster.
NASA's James Webb Space Telescope has confirmed the existence of a protocluster of seven galaxies forming only 650 million years after the big bang.
Webb was able to detect the protocluster galaxies thanks to a magnification boost from Pandora's Cluster, which lies in between.
The mass of Pandora's Cluster is so great that it warps the fabric of space itself, producing a magnifying effect.
Using data, astronomers estimated the protocluster's future development, finding that it could grow in size and mass to become a giant cluster, with thousands of member galaxies.
