“for decisive contributions to the IceCube Neutrino Observatory and the discovery of high-energy neutrinos of astrophysical origin” Did you know? IceCube is a telescope buried in the ice at the South Pole. It uses thousands of light sensors spread through a cubic kilometre of Antarctic ice to catch the faint blue flashes made when neutrinos from deep space hit an atom. Belgian-born Francis Halzen of the University of Wisconsin–Madison spent decades pushing to build it. He was this year's only physics laureate.
