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

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

“Science is all about connectivity,” says Dr Sam Barrell (CBE), Deputy Chief Executive of Europe’s largest single-site biomedical research institute, the Francis Crick Institute. “It’s a highly ...

Astronomers using NASA’s Hubble Space Telescope took advantage of a giant cosmic magnifying glass to create one of the sharpest and most detailed maps of dark matter in the universe. Dark matter is an ...

NASA’s flagship X-ray observatory is starting the calendar with a flourish, unveiling a richly detailed view of a distant ...

Globular clusters maintain their structural integrity primarily due to the angular momentum of their constituent stars, preventing gravitational collapse towards the cluster's center of mass. While ...

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 ...

The distinct spatial distributions of open and globular star clusters in spiral galaxies are a consequence of the interplay between gravity and conserved angular momentum, which facilitates the ...
