Francis Halzen received the 2026 Nobel Prize in Physics for his decisive contributions to the IceCube Neutrino Observatory and the discovery of high-energy neutrinos of astrophysical origin. [^1]

The Royal Swedish Academy of Sciences recognized the Belgian scientist for a central role in building the giant detector located in Antarctica, which captures neutrinos from deep space. [^3]

Researchers using the IceCube telescope found neutrinos with properties indicating they originated from distant regions of space. [^2]

The Nobel Committee praised Halzen for leading an international team of researchers and engineers, describing the observatory as a fantastic tool for a new form of astronomy. [^4]

Ellen Moons, secretary general of the Royal Swedish Academy of Sciences, stated that this year's prize is about ghostly messengers from space. [^5]
