Astronomers have discovered a galaxy cluster burning five times hotter than theoretical models predicted, just 1.4 billion ...

Most astronomers agree that young galaxy clusters should be relatively cool compared to older ones. But researchers recently ...

A small group of young researchers at the Cosmic Dawn Center, Niels Bohr Institute, University of Copenhagen, have, through ...

Scientists have detected a surprisingly hot galaxy cluster dating back to the universe’s infancy. The cluster formed far ...

Only one billion years after the Big Bang, clusters of galaxies were already forming. This discovery pushes back the age of the youngest known galaxy cluster by a third, and shows that the largest ...

Why it's so special: Galaxy clusters act as a magnifying lens, shining light on the faintest and most distant objects — a phenomenon known as gravitational lensing. On the rarest of occasions, galaxy ...

Galaxy clusters are formed by a dense packing of many galaxies, making them the most massive structures in the universe.

The discovery of the most distant galaxy cluster with a specific important trait – as described in our press release – is providing insight into how these gigantic structures formed and why the ...

Astronomers have constructed one of the most detailed images yet of Abell 3667, a giant galaxy cluster about 700 million light-years away from Earth. Reading time 2 minutes When it comes to deep space ...

NASA’s flagship X-ray observatory is starting the calendar with a flourish, unveiling a richly detailed view of a distant system nicknamed the Champagne Cluster. The new composite image captures a ...
