The 2026 Nobel Prize in Physics was awarded to Francis Halzen “for decisive contributions to the IceCube neutrino observatory and the discovery of high-energy neutrinos of astrophysical origin,” the Royal Swedish Academy of Sciences said. Halzen, a Belgian particle physicist at the University of Wisconsin, Madison, led the effort to convert a cubic kilometre of Antarctic ice into the IceCube detector by embedding thousands of basketball-sized light sensors to catch rare flashes from neutrino collisions. IceCube made the first detection of high-energy extraterrestrial neutrinos in 2013 and later identified a cosmic neutrino source 3.7 billion light-years away. The Nobel committee’s citation and Halzen’s remark that “it feels strange” highlighted his emphasis on the early collaborators who joined a risky project; Halzen said he hopes the prize will help secure approval for a new proposal he is working on. The committee awarded 12 million Swedish kronor as the prize sum. Dr Patrick Dunne of Imperial College London said detecting astrophysical neutrinos opens a new lens on the universe, likening the advance to Galileo’s telescope and underscoring IceCube’s role in establishing neutrino astronomy.
