The KM3NeT telescope comprises two detectors, ARCA and ORCA, utilizing seawater to capture Cherenkov light—a bluish glow produced when neutrinos interact with water molecules.

High-energy particles rain down on Earth constantly, but scientists have now detected a doozy: a neutrino blasting in from deep space with an energy far greater than anything we've seen before.
