Astronomers studying a distant galaxy cluster stumbled upon ancient radio signals that might hold clues to the formation of ...

A distant cluster of galaxies is wrapped in a vast halo of high-energy particles that could be the work of supermassive black ...

LOFAR is a massive radio telescope that comprises 100,000 antennas spread across eight European countries. The researchers ...

NASA's James Webb Space Telescope (JWST) has produced a new image of the Bullet Cluster, which is a titanic collision between ...

Astronomers have smashed the record for the largest-known cloud of energetic particles discovered surrounding a galactic cluster—and the find could shake up established physics.. The cluster in ...

The galaxy clusters, which scientists expect will combine at point to form an even larger cluster, is located about 4.3 billion light years from Earth, according to NASA.

A rare discovery of a "relaxed" galaxy cluster that may have formed close to 8 billion years ago could unveil new clues about the big bang.

The galaxy cluster PSZ2 G181.06+48.47 (PSZ2 G181 for short) is about 2.8 billion light-years from Earth. Previously, radio observations from the LOw Frequency ARray (LOFAR), an antenna network in ...

Roughly 2.8 billion light-years from Earth, two galaxy clusters are engaged in a cosmic tussle. These enormous structures last collided about a billion years ago, but now, it appears they’re ...

Around 2.8 billion light-years from Earth lies the galaxy cluster PSZ2 G181.06+48.47, or PSZ2 G181 for short. This galaxy cluster is believed to be made up of two smaller clusters that underwent a ...

Observations show that galaxy clusters generally form as a result of mergers and grow by accreting sub-clusters. CIZA J2242.8+5301 is a well-studied merging galaxy cluster at a redshift of 0.192.
