GoKawiilFrancis Halzen Wins 2026 Nobel Physics Prize for IceCube Neutrino Work
University of Wisconsin-Madison physicist Francis Halzen has received the 2026 Nobel Prize in Physics for his work on astrophysical neutrinos, built around the IceCube Neutrino Observatory he helped develop beneath Antarctic ice. IceCube uses thousands of light sensors in a cubic kilometer of ice to detect neutrinos and has traced them back to cosmic sources such as supermassive black holes.
