Scientists detect record-breaking high-energy neutrino in Mediterranean Sea

Scientists have detected a record-breaking high-energy neutrino using the KM3NeT observatory under construction in the Mediterranean Sea. This neutrino, measured at about 120 quadrillion electronvolts, is 30 times more energetic than any previously detected neutrino. The neutrino likely originated from beyond the Milky Way, with researchers identifying 12 supermassive black holes as potential sources. The KM3NeT project includes two detectors, ARCA and ORCA, designed to capture high-energy and low-energy neutrinos, respectively. Neutrinos are unique cosmic messengers that can travel through matter without interference. This detection marks a significant advancement in understanding cosmic events, although the KM3NeT detectors are still being completed.
