Francis Halzen awarded 2026 Nobel Prize in Physics

On October 6, 2026, the Royal Swedish Academy of Sciences announced that the Nobel Prize in Physics has been awarded to Francis Halzen for his decisive contributions to the IceCube Neutrino Observatory in Antarctica and the discovery of high-energy cosmic neutrinos. The prize carries a monetary reward of 12 million Swedish kronor, approximately 1.2 million dollars.

Halzen, a physicist whose nationality is identified as Belgian in some reports and American in others, first conceptualized the idea in 1988 of using the vast Antarctic ice sheets as a massive detector for neutrinos. His vision led to the creation of the IceCube facility, a giant observatory occupying a cubic kilometer of ice equipped with thousands of light sensors. This technology allows researchers to detect elusive high-energy particles that travel through the universe without changing direction, providing insights into previously unknown cosmic phenomena.

Following this announcement, the Nobel committee continues its schedule with the Chemistry prize on Wednesday, Literature on Thursday, and Peace on Friday. The prize for Economic Sciences is expected to be announced the following Monday.
