IceCube finds 'ghost particles' carrying 10 billion times the energy of solar neutrinos
Nobel-winning physicist's work on Antarctic observatory gives humanity a new window on the universe, Fuller says
Scientists using the IceCube Neutrino Observatory, buried in a cubic kilometre of Antarctic ice, have detected neutrinos carrying roughly 10 billion times the energy of typical solar neutrinos, ultra-rare 'ghost particles' that pass through matter almost undisturbed and may come from the universe's most extreme environments. The find comes as physicist Francis Halzen, whose vision led to the observatory, receives this year's Nobel Prize in Physics for the discovery of high-energy neutrinos of astrophysical origin.
