ESA’s XMM-Newton X-ray observatory has spied hot gas sloshing around within a galaxy cluster – a never-before-seen behaviour that may be driven by turbulent merger events. Galaxy clusters are the ...

Almost all galaxy clusters experience mergers. While a merger takes place, a specific pattern of “spiral” often can be observed in X-ray images. Such a spiral feature is due to the motion of the gas ...

A Naval Research Laboratory (NRL) scientist is part of a team that has recently discovered that vast clouds of hot gas are "sloshing" in Abell 2052, a galaxy cluster located about 480 million light ...

Artist’s impression of the center of the Centaurus Cluster. Blue shows a vast flow of hot gas, white shows galaxies, and reddish brown shows cool gas. Tokyo, Japan – The XRISM collaboration have ...

Like wine in a glass, vast clouds of hot gas are sloshing back and forth in Abell 2052, a galaxy cluster located about 480 million light-years from Earth. X-ray data (blue) from NASA’s Chandra X-ray ...

What can heat distribution within galaxy clusters, which often consist of hundreds to thousands of galaxies, teach astronomers about their formation and evolution? This is what a recent study ...

When the titans of space — galaxy clusters — collide, extraordinary things can happen. A new study using NASA’s Chandra X-ray Observatory examines the repercussions after two galaxy clusters clashed.

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 ...
