An international team of astronomers has employed the Australian Square Kilometer Array Pathfinder (ASKAP) radio telescope to perform radio observations of a galaxy cluster known as Abell S1136.

In 1958 the great extragalactic astronomer George Abell of UCLA compiled a catalog of galaxy clusters. It was extended by Abell and collaborators in 1987 and eventually contained 4,076 clusters.

On Thursday, the European Space Agency drew on the allegory to describe a Hubble Space Telescope image, and why the galaxy cluster Abell 611 confuses astronomers. There’s something unseen in thi ...

A team of scientists pieced together the violent history of the galaxy cluster Abell 2744, also known as Pandora's Cluster, using several different telescopes in space and on the ground.

The cosmic community of Abell 1489 comes into focus in this image of the galaxy cluster taken by the Gemini Multi-Object Spectrograph on Gemini North, one half of the International Gemini Observatory.
