On Tuesday, the Royal Swedish Academy of Sciences awarded the Nobel Prize in physics to Francis Halzen, citing his work on high-energy neutrinos from space. His recognition comes from leading the IceCube Neutrino Observatory at the South Pole and discovering neutrinos of astrophysical origin.
“It was a great surprise and I obviously didn’t expect it,” Halzen said by phone from Italy, where he spoke to the Nobel Committee for Physics.
The person who received the prize was born in Belgium and holds a position at the University of Wisconsin–Madison. Halzen, 82, learned he had won while speaking to the committee over the telephone from Italy.
The Neutrino Telescope at the South Pole
The University of Wisconsin–Madison serves as the lead institution for IceCube, which is a research facility situated at the South Pole in Antarctica, according to its website.
Neutrinos surround us at all times. The sun and similar stars release them, and trillions of these tiny particles travel through our bodies each second. Researchers can’t observe them directly. What they do is measure the effects produced when neutrinos strike other matter, creating flashes of light or charged particles.
From Prediction to Surprise
The study focused on a particular set of neutrinos that researchers treat as messengers from the cosmos, supplying clues about how the universe developed. Halzen’s work on catching these particles at the South Pole goes back to the 1980s.
The prospect of winning the Nobel Prize had been anticipated ahead of time, yet when the announcement arrived, he felt “strange.”.
What the Prize Recognizes
About $1.2 million euros is roughly what the purse amounts to, which works out to some 12 million Swedish kronor.
Mark Pearce, chair of the Nobel Committee for Physics, praised Halzen’s work in a news release. “Francis Halzen has led an international team of researchers and engineers who have provided us with a fantastic instrument. His tenacity and scientific vision has paved the way for a new kind of astronomy,” Pearce said.
Comparing This Year’s Prizes
| Prize | Winner(s) | Field |
|---|---|---|
| Nobel Medicine | Three scientists | Brain imaging with light |
| Nobel Physics | Francis Halzen | Neutrinos from space |
| Nobel Chemistry | To be announced | Chemistry prize |
| Nobel Literature | To be announced | Literature prize |
| Nobel Peace | To be announced | Peace prize |
| Nobel Economics | To be announced | Economic sciences |
This week started with the Nobel Prize for medicine being announced, and the rest of the awards will come out over the next few days. The chemistry prize follows next, then the literature prize. After that, the peace prize is set for Friday, with the economics prize closing things out on Monday.
The Instrument Behind the Discovery
An international group of scientists and builders constructed the IceCube observatory, which has created a fresh means of viewing the cosmos.
