Physics Nobel goes to Francis Halzen for the IceCube telescope buried in Antarctic ice
The Royal Swedish Academy of Sciences awarded the 2026 Nobel Prize in Physics to Francis Halzen, a Belgian-American particle physicist, as sole laureate, for decisive contributions to the IceCube Neutrino Observatory and the discovery of high-energy neutrinos of astrophysical origin. IceCube uses a cubic kilometre of Antarctic ice instrumented with light sensors to catch the rare flashes made when neutrinos hit atoms. The prize is 12 million Swedish kronor. Chemistry follows on Wednesday.
Neutrinos pass through matter almost untouched, so they carry information from the most violent places in the universe. IceCube made neutrino astronomy a working field.
No everyday effect. It is a prize for a decades-long instrument project.
The detail worth knowing is the scale: a telescope the size of a small city's volume, frozen under the South Pole.
