Galaxy cluster Abell 1489 is seen here in an image from the International Gemini Observatory. Galaxy cluster Abell 1489, as imaged by the International Gemini Observatory, contains more than 200 ...

Astronomers have discovered the most distant developing galaxy cluster known to date, shedding light on the formation of large-scale structure in the early universe, a new study reports.

The Perseus galaxy cluster taken by the Subaru Telescope at the Mauna Kea Observatory in Hawaii. The newly discovered subcluster is on the right. Overlaid in blue is the inferred distribution of ...

This Hubble image features a massive cluster of brightly glowing galaxies, first identified as Abell 3192. Like all galaxy clusters, this one is suffused with hot gas that emits powerful X-rays ...

Astronomers have made a groundbreaking discovery in the Perseus galaxy cluster, located 240 million light-years from Earth. For the first time, a dark matter bridge has been detected linking two ...

Astronomers have used the James Webb Space Telescope (JWST) to spot the most distant galaxy cluster ever found, located nearly 30 billion light years away. All seven galaxies in the clump had been ...

The shot features a special galaxy cluster – known as RX J2129 – and three different images of the same supernova-hosting galaxy. RX J2129 is located approximately 3.2 billion light-years from ...

The huge galaxy cluster actually warps the fabric of space and time surrounding it, allowing the cluster to act as a huge lens, magnifying and distorting a spiral galaxy behind it, NASA said in a ...

This particular galaxy cluster lies at a vast distance of 4.6 billion light-years from Earth. Provided by NASA's Goddard Space Flight Center ...

Galaxies and clusters are the ensembles of stars and other astronomical objects bound together by gravitational forces. Galaxies are ordered into galaxy groups, which are in turn organised into ...

A distant galaxy seems to be the only one left in its cluster. It has all the signatures of a galaxy cluster that should contain hundreds of galaxies, but it appears to be all alone, which may ...
