NASA's Great Observatories Weigh Massive Young Galaxy Cluster

Astronomers have used data from three of NASA's Great Observatories to make the most detailed study yet of an extremely massive young galaxy cluster. This rare cluster, which is located 10 billion light years from Earth, weighs as much as 500 trillion Suns. This object has important implications for understanding how these megastructures formed and evolved early in the Universe.

The galaxy cluster called IDCS J1426.5+3508 (IDCS 1426 for short), is so far away that the light detected is from when the universe was roughly a quarter of its current age. It is the most massive galaxy cluster detected at such an early age.
