From a Galaxy Far, Far Away?

Friday, May 10th, 2013

The IceCube neutrino telescope detected two high power neutrinos that researchers believe are from further out in our galaxy, or are from another galaxy.  Most neutrinos IceCube detects come from our Sun, however these two events had higher energy than the more local neutrinos.  The two events had an energy of 1.04 ± 0.16 (August 2011) and 1.14 ± 0.17 (January 2012) PeV.  This is hundreds of times more than the energy of a proton at the Large Hadron Collider.
