🏆Belgian Physicist Francis Halzen Wins the 2026 Nobel Prize in Physics 🌌Francis Halzen, born in the Belgian town of Tienen, has been awarded the Nobel Prize for his contribution to the creation of the IceCube Neutrino Observatory and the study of cosmic neutrinos. 🔭How can we see the invisible? Neutrinos are tiny particles that interact only very weakly with matter and can travel enormous distances across the Universe. By studying them, scientists can learn about distant cosmic objects and powerful processes taking place in space. Under Halzen’s leadership, the unique IceCube Observatory was built in Antarctica. Thousands of sensors embedded deep in the ice detect faint flashes of light produced when neutrinos interact with matter. In this way, the ice itself has become a giant telescope, opening up a new way to explore the Universe. 🤩An idea anticipated by Soviet scientist Moisey Markov Back in 1960, Soviet physicist Moisey Markov proposed building a neutrino telescope underwater. He understood that detecting these elusive particles required a detector on a vast scale — and that the natural environment itself could become part of the instrument. The IceCube project built on the same scientific approach, opening up new possibilities for exploring the cosmos. ✨The history of neutrino astronomy shows how ideas developed by scientists across generations can lay the foundations for discoveries that transform our understanding of the Universe.
