Neutrino telescope in Mediterranean detects most energetic ghost particle ever

A neutrino detector in the Mediterranean Sea has identified the most energetic neutrino ever recorded, approximately 30 times more active than the previous record. Scientists believe it originated outside the Milky Way, but its source is still unknown. Neutrinos are difficult to detect due to their small mass. Researchers measure their interactions with matter, such as when a neutrino collides and produces a muon, which creates flashes of light in the detector. This discovery comes from a deep-sea neutrino observatory still under construction. Scientists suggest that more high-energy neutrinos may exist, but further observations are needed to understand their origins.
