Deep-Sea Telescope Detects Highest-Energy Neutrino Ever Recorded
2025-02-13

The KM3NeT detector, located deep in the Mediterranean Sea, has detected a neutrino with an unprecedented energy of approximately 220 PeV, the highest ever recorded. This event, designated KM3-230213A, provides the first evidence of such high-energy neutrinos originating from cosmic sources. The discovery marks a new chapter in neutrino astronomy and offers a novel observational window into the universe. KM3NeT uses seawater as the interaction medium and detects neutrinos by observing Cherenkov radiation. The detector's final configuration will encompass over one cubic kilometer.
