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

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.

The KM3NeT made the record-breaking detection on February 13, 2023, when the particle lit up one of its two detectors. ARCA, or the Astroparticle Research with Cosmics in the Abyss, ...

A massive particle detected deep under the sea may be the first direct evidence of dark matter, sparking excitement and ...

The international KM3NeT collaboration, in which CNRS plays a leading role, has just detected a neutrino that is thirty times more energetic than any previously detected anywhere in the world.

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 ...

The KM3NeT neutrino telescope, currently under construction, is a gigantic infrastructure on the seabed consisting of two detectors, ARCA and ORCA. KM3NeT uses seawater as the interaction medium ...
