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

We may already have had our first-ever encounter with dark matter, according to researchers who say a mysteriously ...

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 ...

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?

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.

KM3NeT consists of two detectors. The first, called ORCA, is 8,038 feet (2,450 meters) deep off the coast of France and is designed to study how neutrinos oscillate between different types of ...
