The cluster is very bright at X-ray wavelengths and is one of the most extensively studied galaxy clusters at X-ray and radio ...

Researchers working with data from the South Pole Telescope have released a major catalog of galaxy clusters, giving ...

NASA's Hubble Space Telescope captured a stunning image of galaxy cluster CL0016+1609, aiding scientists in studying dark ...

Roughly 2.8 billion light-years from Earth, two galaxy clusters are engaged in a cosmic tussle. These enormous structures last collided about a billion years ago, but now, it appears they’re going ...

Scale in the universe is hard to understand from a purely human perspective. Many times, the math just doesn't sit well with ...

A bizarre "bow-and-arrow" radio galaxy nearly 1.8 million light-years across could reveal how galaxy clusters sculpt some of ...

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 ...

Using the James Webb Space Telescope, astronomers have spotted a massive and densely packed galaxy cluster before such structures were thought to be possible.

X-ray observations of the cluster revealed that it is made up of two galaxy clusters merging along our line of sight.

Astronomers have explained how a galaxy cluster maintains its heat, despite emitting X-rays that cool the hot gas at its center. The group discovered the existence of a fast-moving, high-temperature ...

A UC Davis graduate student who is leading a study of the collision of galaxy clusters 5 billion light years away will discuss the team’s findings today, Jan. 10, in a press briefing at the annual ...

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 ...
