Record-Breaking Cosmic Neutrino Detected Deep Under the Mediterranean
2025-08-15
The KM3NeT detector, located deep beneath the Mediterranean Sea, has detected a cosmic neutrino with an unprecedented energy of 220 PeV, shattering the previous record. After rigorous analysis, the detection was confirmed, but its origin remains a mystery. Possible sources include extreme environments like galactic centers, gamma-ray bursts, or interactions with the cosmic microwave background. This discovery opens a new window into ultra-high-energy neutrino astronomy.
