The 2026 Physics Nobel recognized Francis Halzen, the IceCube scientist who led the transformation of clear Antarctic ice into a gigaton-scale neutrino detector at the geographic South Pole. IceCube measures flashes of Cherenkov light from charged particles produced by rare neutrino interactions. The instrumented volume is about 1 cubic kilometre; the established detector has 86 strings and 5,160 in-ice optical modules. Its 2013 detection of high-energy astrophysical neutrinos opened neutrino astronomy, while the 2017 neutrino–gamma-ray association pointed toward a blazar source. The laureate, instrument, location and signal mechanism are separate exam facts.
