Deep-Sea Telescope Detects Most Energetic Neutrino Ever Recorded

The KM3NeT detector in the Mediterranean Sea observed a 220 PeV neutrino, marking a breakthrough in neutrino astronomy and cosmic event research.

The KM3NeT ARCA detector recorded a 220 PeV neutrino on February 13, 2023, the highest energy neutrino ever detected.
This discovery, named KM3-230213A, was achieved using Cherenkov light detection in deep-sea water 3.5 kilometers below the Mediterranean Sea.
The observation provides critical insights into high-energy cosmic phenomena, with potential sources including black holes, supernovae, or pulsars.
The KM3NeT project, still under construction, demonstrates significant potential in studying neutrinos despite operating at only one-tenth of its planned capacity.
The detection highlights the importance of international collaboration, with Dutch scientists playing a pivotal role in the telescope's development and data analysis.
