The IceCube Neutrino Observatory at the South Pole is a large array of photodetectors buried in ice. In 2013, the instrument reported signals from the highest energy neutrinos ever observed. Now, two teams of researchers have independently estimated the type, or flavor, of these neutrinos. As opposed to an earlier analysis, these new results are consistent with the neutrinos coming from cosmically large distances. Further work may begin to probe the physics going on at the neutrino sources.
