Scientists detect most energetic neutrino ever recorded in Mediterranean Sea

A team of scientists has detected the most energetic neutrino ever recorded, with an energy of 220 peta-electronvolts. This discovery was made using the KM3NeT telescope in the Mediterranean Sea, which monitors neutrino interactions through the Cherenkov effect. The neutrino was detected on February 13, 2023, after extensive verification and simulation. The event produced about 28,000 photons, indicating a significant interaction, despite being a small number compared to typical light sources. Researchers believe this neutrino originated from cosmic sources, possibly blazars or cosmic ray interactions. This finding enhances understanding of high-energy phenomena in the universe and supports theoretical models predicting high-energy neutrinos.
