Galaxy clusters are the most massive objects in the universe held together by gravity, containing up to several thousand individual galaxies and huge reservoirs of superheated, X-ray-emitting gas. The ...

A newly discovered galaxy cluster, blazing with unexpectedly hot gas just 1.4 billion years after the Big Bang, is forcing scientists to rethink the early universe. The research, published in Nature, ...

Scientists have detected a surprisingly hot galaxy cluster dating back to the universe’s infancy. The cluster formed far earlier and burned far hotter than current models predict. Researchers believe ...

While peering into some of the oldest regions of the known universe — dating back to just 1.4 billion years after the Big Bang — an international team of astronomers made a puzzling discovery. As ...

The Champagne Cluster is a rare and beautiful example of two galaxy clusters smashing together. Its festive name comes from both its New Year’s Eve discovery and its bubbly appearance in space. Images ...

Current theories say young galaxy clusters should be relatively cool compared to older ones. But researchers recently found a very young cluster that was shockingly hot. Study author Dazhi Zhou says ...

A small group of young researchers at the Cosmic Dawn Center, Niels Bohr Institute, University of Copenhagen, have, through observations of the early stages of an extremely large galaxy cluster's ...

Artist’s impression of a forming galaxy cluster in the early Universe: radio jets from active galaxies are embedded in a hot intracluster atmosphere (red), illustrating a large thermal reservoir of ...
