Francis Halzen wins 2026 Nobel Prize in Physics for IceCube neutrino observatory

Physicist Francis Halzen has been awarded the 2026 Nobel Prize in Physics for founding the IceCube Neutrino Observatory and for discovering high-energy neutrinos originating from deep space. IceCube, built below the Antarctic ice, detects rare interactions between neutrinos and atoms, capturing particles emitted by cosmic events like supernovae and gamma-ray bursts. Halzen noted the project succeeded within two years of operation, despite initial skepticism from the physics community.
