The Nobel winner searching for deep-space neutrinos in Antarctica

It’s Nobel Prize week, and this year’s prize in physics went to Francis Halzen “for decisive contributions to the IceCube Neutrino Observatory and the discovery of high-energy neutrinos of astrophysical origin.” The IceCube is a massive neutrino detector that covers a cubic kilometer of Antarctic ice, and looks for high-energy neutrinos coming from deep space. 

In 2013, Ira spoke with physicist Francis Halzen about the decision to build the IceCube at the South Pole and the challenges of constructing a map of the cosmos with neutrinos.
