The NASA/ESA Hubble Space Telescope has unveiled a stunning image of the Abell 209 galaxy cluster, located 2.8 billion ...

The gas is so hot, between 10 million and 100 million degrees Celsius, that it radiates in powerful X-rays. By combining a new image of a giant galaxy cluster with older X-ray data, scientists at ...

The Chandra X-ray Observatory view of galaxy group NGC 4839 has revealed that it is "plunging into the Coma galaxy cluster ...

This unprecedented view of the Bullet Cluster provided by the James Webb Space Telescope and the Chandra X-ray Observatory ...

The intracluster gas of a galaxy cluster typically cools over time, first emitting X-rays, then cooling to emit ultraviolet light, and finally, emitting electromagnetic wavelengths down to the ...

Hot gas bridges galaxy cluster pair Date: November 20, 2012 Source: European Space Agency (ESA) Summary: Space telescope has made the first conclusive detection of a bridge of hot gas connecting a ...

Galaxy clusters are comprised of three main components: individual galaxies, multimillion-degree gas that fills the space between the galaxies, and dark matter, a mysterious form of matter that is ...

The hot gas in the galaxy cluster Abell 2052 is being sloshed back and forth. The sloshing was set in motion when a small cluster smashed into the larger central one.

Once a galaxy is absorbed by a massive cluster, its star formation soon comes to a halt. For years, researchers have tried to figure out why this phenomenon, known as “quenching,” occurs.

NASA's Chandra X-ray telescope detected two new streams of gas trailing behind a galaxy within a cluster called Zwicky 8338, or Z8338, located about 670 million light-years from Earth.Together ...

Astronomers have discovered a previously hidden "cosmic fuel tank" in an infant cluster of forming galaxies. This vast reservoir of cool molecular gas is found in the protocluster known as SPT2349 ...

Astronomers have discovered a new kind of star system: Elongated and clumpy clusters of young, hot, blue stars, formed out of gas blown out of a galaxy as it rams its way through a galaxy cluster.
