Francis Halzen Wins 2026 Nobel Prize for Neutrino Research
Francis Halzen is a physicist who studies neutrinos, tiny particles that are very hard to detect.
Trillions of them pass through people every second, usually without interacting with anything.
In the 1980s, Halzen began thinking about using ice at the South Pole to find them.
That idea helped lead to the IceCube observatory in Antarctica.
It looks for flashes of light or other signs created when a neutrino rarely hits another particle.
These detections can give scientists clues about events far away in space.
Halzen led an international team that helped build and run the observatory.
He won the 2026 Nobel Prize in Physics for his work.
He said he was surprised when he received the news by phone in Italy.
Belgian-born physicist Francis Halzen won the 2026 Nobel Prize in Physics for work on high-energy neutrinos and the IceCube Neutrino Observatory.
Halzen began exploring ways to detect neutrinos at the South Pole in the 1980s.
IceCube uses Antarctic ice to detect light and charged particles produced by rare neutrino interactions.
The University of Wisconsin-Madison is the observatory’s lead institution, and Halzen led its international research and engineering team.
Halzen said the Nobel Committee’s call, which came while he was in Italy, was a surprise.
