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

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

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

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

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 ...

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 ...

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

LOFAR is the largest radio telescope on Earth and headquartered in the Netherlands. Since it opened in 2010, it has had additional antennas installed throughout Europe to boost its resolution, ...

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.” ...

But in the five years since Musk’s private company, SpaceX, began launching its Starlink satellites, an escalation in radio wave emissions has made it much harder for LOFAR to make observations.

A new study reveals that Generation 2 Starlink satellites are leaking up to 30 times more radio waves than their predecessors. If SpaceX continues to deploy the newer versions as planned, we could ...
