# Francis Halzen wins Nobel Prize in Physics for work on 'ghost particles'

Physicist Francis Halzen has been awarded the Nobel Prize in Physics for his research on neutrinos, near-massless "ghost particles" that pass through matter almost undetected. Halzen is a leading figure behind the IceCube Neutrino Observatory, which uses Antarctic ice to capture these particles. The recognition highlights how neutrino astronomy has opened a new window on the universe's most violent events.

**Importance:** 4/5
