Francis Halzen awarded Nobel Prize in Physics for cosmic neutrino research

Recognition for a revolution in elementary particle physics

The committee announced the name of the 2026 Nobel Prize in Physics laureate. Francis Halzen received the award for his fundamental contribution to the development and implementation of the giant IceCube detector.

This installation is embedded in the thick Antarctic ice and has become a key instrument for detecting ultra-high-energy neutrinos. Such particles are produced during the most extreme cosmic events, including the absorption of matter by black holes.

How the IceCube telescope works

Neutrinos differ from other particles in that they interact with matter very little. This is why specialised systems, such as IceCube, buried in the ice layers of Antarctica, are required to detect them.

The detector has given scientists the ability to study regions of the Universe that were invisible to traditional optical telescopes. Observing high-energy neutrinos has opened a new “window” for studying the most powerful processes in space.
