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 ...

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 ...

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 ...

Two new studies have measured the expansion of the Universe in our immediate cosmic neighborhood using a novel method that analyzes the motion of two nearby galaxy groups within their surrounding ...

The Centaurus Cluster is a collection of hundreds of galaxies located about 145 million light years from Earth. At the center of the cluster is a large elliptical galaxy called NGC 4696. Buried within ...

Using a novel technique that examines the motion of two nearby galaxy groups within their surrounding cosmic flow, an ...
