Galaxy cluster Abell 1489, as imaged by the International Gemini Observatory, contains more than 200 of the gravitationally-bound systems of stars, stellar remnants, interstellar gas and dust. Galaxy ...

Three enormous and peculiar radio light rings were discovered far, far outside our own galaxy, shedding more light on one of ...

Lang (Perimeter Institute) A vast river of neutral hydrogen bridges two galaxies that are beginning to enter the monstrous Virgo Cluster, and this structure is helping astronomers better understand ...

Galaxy clusters are often described by superlatives. After all, they are huge conglomerations of galaxies, hot gas, and dark matter and represent the largest structures in the Universe held together ...

The galaxy cluster is filled with bubbles blown into X-ray emitting gas, producing some of the deepest sounds ever heard. When you purchase through links on our site, we may earn an affiliate ...

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 ...

New findings explain the Phoenix cluster's mysterious starburst. Data confirm the cluster is actively cooling and able to generate a huge amount of stellar fuel on its own. The core of a massive ...

Cosmology scientists at the Lawrence Berkeley National Laboratory have made a rare discovery: a cluster of galaxies that span most of the observable universe. This cluster — the Carousel Lens — is ...

The galaxy cluster PLCKG 287.0+32.9, located 5 billion light-years away, exhibits an exceptionally violent collision of three subclusters, characterized by extensive turbulence and shock waves.

A massive, spacetime-warping cluster of galaxies is the setting of today’s NASA/ESA Hubble Space Telescope image. The galaxy cluster in question is Abell 209, located 2.8 billion light-years away in ...
