Scientist Who Hunted Ghost Particles in Antarctic Ice Wins Nobel Prize in Physics

Belgian-born physicist Francis Halzen has been awarded the 2026 Nobel Prize in Physics for his pioneering work at the IceCube Neutrino Observatory, which enabled the detection of high-energy cosmic neutrinos using light sensors embedded in the Antarctic ice sheet.

The Announcement of the Prize

Causing a major ripple in the scientific community, Francis Halzen, known for his groundbreaking work in Antarctica, has won the 2026 Nobel Prize in Physics. The prize announcement was made in Stockholm.

In the announcement made by the Royal Swedish Academy of Sciences, it was emphasized that Halzen's vision opened a brand-new window in the field of astronomy.

The Ice Detector in Antarctica

Eighty-two-year-old physicist Francis Halzen, who works at the University of Wisconsin-Madison, developed the idea of transforming the massive Antarctic ice sheet into a unique detector.

This special system, in which thousands of light sensors are embedded, successfully captures high-energy neutrinos originating from distant galaxies and violent cosmic processes.

The Value Enabled by the Prize

Halzen, who reached the prize through his efforts to solve the mystery of rare neutrinos, is known for his decades of scientific leadership and determination.

As part of the Nobel Prize in Physics won, a financial award amounting to 12 million Swedish kronor is presented to the recipient.
