The Nobel organization announced October 6 that Francis Halzen receives the 2026 physics prize for decisive contributions to IceCube and high-energy astrophysical neutrinos. Followed source ChineseWSJ reported the award.

IceCube uses roughly one cubic kilometre of Antarctic ice. Sensors register light produced when neutrinos rarely interact with matter. Their weak interactions demand a huge detector, but also allow them to carry information about energetic cosmic processes, complementing observations made with light.

Halzen proposed the concept in 1988 and the observatory was completed in 2011. The October 6 development is the award for that long effort. It does not mean the instrument has just opened or every detected neutrino has an identified source.
