Two years ago, a neutrino collided with matter and produced a tiny particle called a muon that pinged through the underwater detector, producing flashes of blue light. The researc

What we have discovered is, we think, the most energetic neutrino ever recorded on Earth,” said Paul de Jong, a physicist at the University of Amsterdam and current spokesperson for the global collaboration of roughly 350 scientists who were involved in the discovery.

High-energy particles rain down on Earth constantly, but scientists have now detected a doozy: a neutrino blasting in from deep space with an energy far greater than anything we've seen before.
