The Most Energetic Neutrino Ever Detected Could Be Primordial

This illustration shows a neutrion interacting with ordinary matter and releasing a muon. The muon moves very rapidly, leaving the telltale blue glow of Cherenkov radiation. The most energetic neutrino ever observed was detected by the muon it created. It's energy was so great that researchers think it may have been an elusive cosmogenic neutron. Image Credit: Nicolle R.

Neutrinos are very difficult to detect. And when they are detected, pinpointing their sources is likewise difficult. New research shows that the most energetic neutrino ever detected must have had an extraordinarly energetic source. It could even be primordial.
