Francis Halzen wins 2026 Physics Nobel Prize
The gist
Belgian physicist Francis Halzen won the 2026 Nobel Prize in Physics for his work on the IceCube neutrino observatory at the South Pole.
The prize recognizes the detection of high-energy neutrinos from space, a window into the cosmos.
How it unfolded
- 2013IceCube discovered astrophysical neutrinos, though the sources were not known at the time.
- 2023IceCube announced the observation of neutrinos from our own galaxy, the Milky Way.
- 2025 –2026The IceCube Upgrade was installed to lower the energy threshold and better calibrate the ice.
