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

The discovery, made with the LOFAR (LOw Frequency ARray) radio instrument in Europe, indicates that galaxy clusters, which ...

LOFAR is a massive radio telescope that comprises 100,000 antennas spread across eight European countries. The researchers used it to study SpARCS1049, a galaxy cluster so far away that the light we ...

LOFAR detects a faint radio 'mini-halo' from 3.8 billion years ago, revealing how galaxy clusters evolved in the early universe.

An early universe radio jet spanning an astonishing 200,000 light years has been discovered by the International Gemini ...

A faint radio glow reveals a million-light-year halo enveloping one of the earliest galaxy clusters, hinting that energetic ...

Astronomers have discovered the most distant mini-halo ever seen—10 billion light-years away—revealing that galaxy clusters ...

Abell 2255 is a cluster containing between 300 and 500 constituent galaxies, many of which are merging. It's located around 800 million light-years from Earth and spans around 16.3 million light-years ...

Views of a massive galaxy cluster Abell 2256 have been captured by NASA’s Chandra X-ray Observatory, ESA’s XMM-Newton and ...

The jet is known as Quasar J1601+3102, and it was first spotted by astronomers using the Low Frequency Array (LOFAR). Researchers estimate that the jet spans nearly 200,000 light-years, more than ...

Our LOFAR survey only covered 15 percent of the sky. And most of these giant jets are likely difficult to spot, so we believe there are many more of these behemoths out there.” ...
