IceCube Captures Extragalactic Neutrinos

Could've come from a galaxy far far away


Two ultra-high-energy neutrinos captured by the IceCube experiment probably came from outside the Galaxy, according to an analysis posted by the collaboration today.

"We're pretty excited about it. They're the highest energy neutrinos that have ever been seen," says Thomas Gaisser, an IceCube member at the University of Delaware in Newark. IceCube consists of 86 strings of detectors sunk in a cubic kilometre of ice near the South Pole.
