In February 2023, an underwater telescope called KM3NeT, anchored several miles beneath the Mediterranean Sea, recorded the brightest particle track ever seen in the universe. A single flash raced ...

Scientists have never directly detected dark matter, but some wonder if one high-energy detection in 2023 could be a rare ...

Of KM3NeT’s two detectors, one is dedicated to more mundane atmospheric neutrinos. The other, dubbed ARCA, is located under nearly 3.5 kilometers of water off the coast of Sicily and is designed ...

KM3NeT looks about as much like a traditional telescope as, say, a rhinoceros does. It consists of indented spheres of metal standing guard over smaller glass spheres hanging from strings.

Amazingly, KM3NeT detected this particle while under construction, using only 20 percent of its photodetectors. Neutrinos lie at the frontier of scientific unknowns about the universe.

Scientists have detected the highest energy ghost particle neutrino ever, but did it come from a supermassive black hole particle accelerator aiming its jet straight at Earth or from a cosmic fossil?

In February of 2023, the Cubic Kilometer Neutrino Telescope (KM3NeT) detected a neutrino some 35 times higher in energy than any previous detection. A new study posits that this muon might be the ...

Does KM3NeT's early detection with ARCA bode well for finally being able to detect such neutrinos more regularly? Advertisement. Advertisement "We certainly hope so!" said de Jong.
