Summary

  • On 23 February 2023, a particle detector recorded the arrival of the highest-energy neutrino ever detected, with an estimated energy of 220 petaelectronvolts (PeV).
  • While it doesn’t provide any clues as to the nature of its source, the detection of this single particle is exciting as it suggests there could be Cosmic processes – and possibly even new phenomena – taking place across the universe.
  • At present, the possibilities for the neutrino’s origin include its being a manifestation of a new ultra-high-energy cosmic process, or a marker for previously unmapped astrophysical sources.
  • Therefore, the detection of further particles like this would help scientists to understand more about the cosmos.
