Researchers detect record-breaking neutrino during Mediterranean seafloor detector construction

Researchers announced the detection of the most energetic neutrino ever recorded while building a new detector on the Mediterranean seafloor. The detector, only 10% complete, identified a neutrino with energy levels over 10,000 times greater than those produced by the Large Hadron Collider. The detected neutrino had an energy of at least 60 Peta-electronVolts, surpassing previous records of around 10 PeV. Its origin has been traced to outside our galaxy, with several potential sources identified in the distant Universe. Neutrinos rarely interact with matter, making detection challenging. The new detector aims to capture these elusive particles by maximizing interactions with seawater, similar to the IceCube detector in Antarctica, which uses ice to detect neutrinos from space.
