US EditionRecord-Energy Neutrino May Have Begun Its Journey in Blazars
KM3NeT study models blazar population as source of record 220 PeV neutrino, consistent with gamma-ray limits and rare ultra-high-energy neutrino observations.

Black hole-powered blazars may explain the highest-energy neutrino ever detected
A single particle cut through the Mediterranean in February 2023 carrying an almost absurd amount of energy. Detected deep off the coast of Sicily by the KM3NeT/ARCA neutrino telescope, the neutrino clocked in at about 220 petaelectronvolts, making it the most energetic neutrino ever recorded. That one event, known as KM3-230213A, stood out immediately. Its energy was more than an order of magnitude above previously observed high-energy neutrino…
Blazar population may power record energy neutrino
Paris, France (SPX) Mar 09, 2026 Three years ago, the KM3NeT/ARCA neutrino detector in the Mediterranean Sea recorded the passage of an ultra-energetic cosmic neutrino, the most energetic neutrino ever detected, with an energy of about 220 PeV, more than an order of magnitude above previously observed high-energy neutrinos. The event drew wide attention because its origin was unknown and challenged existing models for the produ
The most energetic neutrino ever observed – an almost phantom particle capable of crossing entire planets without interacting with matter – could come from distant galaxies with giant black holes. This has now been proposed by scientists who investigate the event detected in 2023 at the bottom of the Mediterranean Sea, after analyzing for years the origin of that extraordinary particle. The neutrino was recorded by the submarine telescope KM3NeT…
