Francis Halzen has been awarded the 2026 Nobel Prize in Physics. The honour was announced on October 6.

Halzen was recognised for his work on the IceCube neutrino observatory. The facility sits deep in Antarctic ice.

IceCube detects neutrinos, ghostly particles from deep space. The observatory has opened a new window on the universe.

Halzen is widely seen as the driving force behind the project. He spent decades pushing the idea that became IceCube.

The prize carries the usual medal and cash award. It caps a career that changed how we observe the cosmos.

The Nobel Prizes are announced each October in Stockholm. The physics prize carries a medal and a cash award of 11 million Swedish kronor. Halzen’s win was welcomed by the physics community. IceCube is funded by multiple countries. The observatory has detected neutrinos from distant galaxies. The discovery opened the field of neutrino astronomy. The announcement was made at the Royal Swedish Academy of Sciences. Halzen thanked his collaborators. The award ceremony is in December.
