**STOCKHOLM, Sweden, Oct. 12, 2026 —** The Royal Swedish Academy of Sciences has awarded the 2026 Nobel Prize in Physics to Francis Halzen for decisive contributions to the IceCube Neutrino Observatory and the discovery of high-energy neutrinos of astrophysical origin.[^1]

Halzen is an 82-year-old physicist born in Belgium. He has worked at the University of Wisconsin-Madison since 1972, and first conceived the idea for the IceCube observatory in the late 1980s.[^2]

The IceCube Neutrino Observatory operates nearly 100 instrumented ice holes near the South Pole.[^3]

In 2013, the observatory presented the first solid evidence of high-energy neutrinos of cosmic origin.[^4]

The Nobel committee noted Halzen's work was instrumental to the construction of the observatory, which glimpsed the first high-energy neutrinos from faraway galaxies.[^5]

**Impact Insight.** Neutrinos are nearly massless particles that pass through almost anything, so catching even a few needs an enormous detector, which is why IceCube uses a block of deep Antarctic ice. There is no direct planetary-defense link: this is particle astrophysics, included as major news from the wider world of space science.
