Belgian physicist Francis Halzen won the Nobel Prize in Physics for his work on subatomic particles at the South Pole. The prize recognized his contributions to the IceCube Neutrino Observatory and the discovery of high-energy neutrinos from space. Halzen, a professor at the University of Wisconsin-Madison, was praised for his vision and leadership in developing an observatory that uses a cubic kilometre of ice equipped with light sensors to detect rare subatomic particles called neutrinos.

Story summary
On Tuesday, the Nobel Prize in Physics was awarded to Francis Halzen, a Belgian physicist affiliated with the University of Wisconsin–Madison, for his pioneering work on detecting high-energy neutrinos from space using the IceCube Neutrino Observatory at the South Pole. The observatory uses one cubic kilometer of Antarctic ice as its detection medium to spot flashes of light caused by rare collisions between neutrinos and atomic nuclei. This discovery allows researchers to study extremely energetic processes in distant parts of the universe. Halzen first proposed his vision for detecting these particles in 1988, and the IceCube Observatory was completed in 2011. The prize, worth 12 million Swedish kronor (approximately $1.2 million), recognizes Halzen's "decisive contributions to the IceCube Neutrino Observatory" and his discovery of neutrinos with astrophysical origins.

The Royal Swedish Academy of Sciences noted that Halzen’s “vision and scientific leadership” had been fundamental for the observatory, which it described as “a cubic kilometre of ice that is equipped with light sensors”.
asserted
that → note → sensors
Using the observatory, researchers can capture neutrinos — rare subatomic particles — “from extremely energy-rich processes in the distant universe”.
“This Nobel Prize is about a giant ice cube positioned at the South Pole of our globe.

The award is the second Nobel of the season, after the Medicine Prize was awarded on Monday to US psychiatrist and neurologist Karl Deisseroth and German scientists Peter Hegemann and Georg Nagel.

The perhaps most keenly anticipated award — the peace prize — is due on Friday.
