"History shows us that whenever you do open a new 'energy window,' you never really know what you're going to find. It's completely unexplored." ...

KM3NeT comprises two large neutrino detectors at the bottom of the Mediterranean. One called ARCA - 3,450 meters (2.1 miles) ...

A deep-sea detector glimpsed a particle with 220 million billion electron volts of energy — around 20 times as energetic as any neutrino seen before.

An extraordinary event consistent with a neutrino with an estimated energy of about 220 PeV (220 x 1015 electron volts or 220 ...

A “ghost particle” discovered by a detector in the Mediterranean carried 30 times more energy than any neutrino observed to ...

The researchers state that the discovery of this extremely high-energy neutrino is the first concrete proof that the universe produces neutrinos at these incredible energy levels.

The team announced its “ultrahigh energy” neutrino on Wednesday, in a paper published in the journal Nature. The finding brings physicists and astronomers one step closer to understanding just what, ...

An international research network has observed a cosmic neutrino with a record-breaking energy in the depths of the Mediterranean. Würzburg ...

A pair of astrophysicists with Aix- Marseille Université, CNRS, and Institut Universitaire de France have developed a new ...

The most powerful neutrino on record, with help from a deep-sea sensor, has provided the first evidence for high-energy ...
