AI Summary

Francis Halzen, an 82‑year‑old physicist born in Belgium and now a professor at the University of Wisconsin–Madison, has been awarded the Nobel Prize in Physics. The prize recognizes his decades‑long effort to detect high‑energy neutrinos originating from outer space, a project he began in the 1980s. Halzen’s work centers on a massive detector embedded in the Antarctic ice at the South Pole, which captures fleeting neutrino interactions. The award highlights the long‑term commitment of his research program and its breakthrough in astrophysical particle detection.
