Super neutrinos spotted
Two super-high-energy particles have been detected by IceCube, the massive neutrino telescope buried in Antarctic ice. IceCube is looking for neutrinos that point toward the still-unknown astrophysical objects responsible for slinging ultra-high-energy cosmic rays toward Earth. These two neutrinos, one seen in August 2011 and the other in January 2012, have enough energy to be from an ultra-high-energy cosmic ray source, such as a gamma-ray burst.
