Event Overview
The KM3NeT (Cubic Kilometre Neutrino Telescope) collaboration has achieved a significant breakthrough with the detection of an ultra-high-energy neutrino in the Mediterranean Sea. This neutrino, carrying 220 peta-electronvolts (PeV) of energy, dwarfs previous records and presents a unique opportunity to study extreme astrophysical phenomena. The detection was made using the ARCA detector, part of the KM3NeT infrastructure, located off the coast of Sicily. The event highlights the potential of neutrino astronomy to reveal insights into the most energetic and distant processes in the universe, like exploding stars and supermassive black holes. This groundbreaking observation may unlock secrets of the cosmos by studying these 'ghost particles'.
