Belgian physicist Professor Francis Halzen has been awarded the Nobel Prize in Physics for pioneering the IceCube neutrino observatory at the South Pole.
The detector uses a cubic kilometre of ice fitted with light sensors to capture neutrinos, revealing violent cosmic processes such as supernovae and black‑hole collisions.
Halzen’s vision, first presented in 1988, turned a challenging idea into a functional observatory that now feeds global scientific community with data.
The Royal Swedish Academy of Sciences praised his vision and leadership, noting that his work made a complex concept a reality for physics research worldwide.
