An extraordinary event consistent with a neutrino with an estimated energy of about 220 PeV (220 x 1015 electron volts or 220 million billion electron volts), was detected on February 13, 2023, by the ARCA detector of the kilometer cubic neutrino telescope (KM3NeT) in the deep sea.

Neutrinos are very mysterious particles,” says Damien Dornic, one of the co-authors of a new paper published February 12 in Nature that describes the detection of the decay products of an extremely high energy neutrino by the Kilometer Cubed Neutrino Telescope (KM3NeT),

Using an observatory under construction deep beneath the Mediterranean Sea near Sicily, scientists have detected a ghostly subatomic particle called a neutrino boasting record-breaking energy in another important step toward understanding some of the universe's most cataclysmic events.

Although still under construction, the sea-floor KM3NeT detector spotted a neutrino 20 times more powerful than any previously detected.

In an unprecedented milestone for astrophysics, the cubic-kilometer neutrino telescope (KM3NeT), located in the depths of the sea, has detected a neutrino with an estimated energy of approximately 220 petaelectronvolts (PeV),

An international collaboration of 68 institutes, including the French National Center for Scientific Research (CNRS), has found evidence of the passage of one of these particles off the coast of Sicily,

What we have discovered is, we think, the most energetic neutrino ever recorded on Earth,” said Paul de Jong, a physicist at the University of Amsterdam and current spokesperson for the global collaboration of roughly 350 scientists who were involved in the discovery.

Physicists have detected the highest-energy 'ghost particle' ever felt on Earth, with nearly 100 times more energy than any neutrino previously detected.
