First Ultra-High Energy Neutrino Detected in Deep-Sea Telescope (phys.org)
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.
