The team announced its “ultrahigh energy” neutrino on Wednesday, in a paper published in the journal Nature. The finding brings physicists and astronomers one step closer to understanding just what, exactly, is out there thrusting particles to such unfathomable speeds.

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

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.
