The 2026 Nobel Prize in Physics has been awarded to Francis Halzen of the University of Wisconsin-Madison 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, led the project that embedded thousands of basketball-sized light detectors into a cubic kilometre of clear Antarctic ice to catch faint flashes from neutrino collisions. IceCube made the first detection of high-energy extraterrestrial neutrinos in 2013 and later identified a first cosmic source about 3.7 billion years away. Halzen said he received the news while travelling in Italy and called the award strange, adding he hoped it would reflect on the people who joined the risky early project. The Nobel committee set the prize at 12 million Swedish kronor, about £900,000. The award recognizes IceCube’s role in creating a new kind of astronomy that complements observations with light and gravitational waves and it underscores continuing global efforts such as Dune and Hyper-Kamiokande to study neutrinos.
