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 high-energy particle detected in 2023 is not a neutrino after all, but something far ...

For some background, the neutrino was detected on February 13, 2023 by the European Union-funded KM3NeT, the Cubic Kilometre Neutrino Telescope. Neutrinos are ghostly particles because they have ...

How do you speed up something that only interacts regularly with itself? That's the question gripping astrophysicists at the Cubic Kilometer Neutrino Telescope (KM3NeT). In 2023, before the ...

KM3NeT is only at the beginning of its journey—this discovery popped up when the device was using only 21 of its planned 230 detection lines.

A huge detector in the Mediterranean Sea spotted the most energetic neutrino from space to date. The particle could shed light on the universe’s most extreme phenomena.

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?

The highest-energy cosmic neutrino detected to date was observed by KM3NeT, which sits at the bottom of the Mediterranean Sea near Sicily, Italy and Provence, France.

The KM3NeT telescopes, currently under construction, will catch high-energy neutrinos that could reveal secrets of the cosmos.

However, the muon that struck the KM3NeT detector in 2023 can’t have been one of these muons: unlike cosmic ray muons, which descend from above, it arrived on a nearly horizontal trajectory.
