In brief

Francis Halzen has won the Nobel Prize in physics for his work on neutrinos, which are tiny cosmic particles often called ghost particles. Although trillions of them pass through our bodies every second, they are very difficult to detect. Halzen realized that the ice in Antarctica could help scientists visualize these particles, leading to the construction of the IceCube Neutrino Observatory. The eighty-two-year-old Belgian scientist was surprised by the news while traveling in Italy.

On Tuesday, the Royal Swedish Academy of Sciences awarded the Nobel Prize in physics to Francis Halzen. The eighty-two-year-old Belgian scientist has worked for many years at the University of Wisconsin-Madison. Ellen Moons, who is the first female secretary-general of the academy, announced the prize in Stockholm. The award includes prize money of twelve million Swedish kronor, which is about one point two million dollars.

Halzen won the prize for his research on rare neutrinos, which are tiny cosmic particles with a small mass. Although trillions of these ghost particles pass through our bodies every second, they are incredibly difficult to see. Scientists cannot observe them directly, so they must measure what happens when they collide with other matter. These collisions produce tiny flashes of light that scientists can detect.

Halzen realized that ice at the South Pole could help scientists these messengers from the cosmos. His ideas led to the construction of the IceCube Neutrino where many researchers joined his quest. Experts say that this Antarctic experiment has provided a way of understanding the universe.

The Nobel committee contacted Halzen by phone while he was traveling in Italy. During the broadcasted call, he admitted that the prize was a great surprise and made him feel quite strange. He hopes this award will help him get a new proposal approved.

Following the announcement, Belgian Prime Minister Bart De Wever congratulated Halzen on social media. He pointed out that Halzen is the eleventh Belgian to win a Nobel prize. He called the award an impressive of his lifetime of work.
