The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Physics 2026 to Francis Halzen “for decisive contributions to the IceCube Neutrino Observatory and the discovery of high-energy neutrinos of astrophysical origin.” 

Francis Halzen has laid the foundation for an entirely new type of astronomy. His idea was to use glacial ice at the South Pole to capture the secretive particles called neutrinos. The result was the IceCube Neutrino Observatory, which can track neutrinos that originate in the distant cosmos.
