STOCKHOLM – The 2020 Nobel Prize for physics is being announced Tuesday, an award that has in the past honored discoveries about the tiniest of particles and the vast mysteries of outer space. A panel at the Karolinska Institute in Stockholm will announce the recipient some time after 11:45 a.m. (0945 GMT; 5:45 a.m. EDT). It is common for several scientists who worked in related fields to share the prize. On Monday, the Nobel Committee awarded the prize for physiology and medicine to Americans Harvey J. ___Read more stories about Nobel Prizes past and present by The Associated Press at https://www.apnews.com/NobelPrizes

Nobel Physics Laureate James Peebles attends a press conference at the Royal Swedish Academy of Sciences in Stockholm, Sweden Saturday, Dec. 7, 2019. Didier Queloz was one of several Nobel laureates who spoke about climate change at a news conference Saturday in Stockholm. “We'd better spend our time and energy trying to fix it.”Several other Nobel winners also urged that climate change be taken seriously. The remarks came as a two-week global summit on climate change is taking place in Madrid. Esther Duflo, one of the Nobel economics laureates, cautioned that dealing with climate change “will require a change in behavior, particularly in the rich countries” that are heavy consumers of goods and energy.

But there's one thing at least four of this year's US Nobel Prize laureates share. Immigrants have won 38% of the Nobel Prizes awarded to Americans in chemistry, medicine and physics since 2000, and 35% of the Nobel Prizes awarded to Americans in those fields since 1901, the foundation says. UK-born M. Stanley Whittingham, a professor at Binghamton University in New York, was one of three awarded the Nobel Prize in chemistry. And Canadian-born James Peebles, a professor at Princeton University, was one of three recipients of the Nobel Prize in physics. "The findings do not mean America should welcome only Nobel Prize winners.

The 2019 Nobel Prize in Literature has been awarded to Austrian author Peter Handke, while the 2018 award, postponed from last year, was given to Polish author Olga Tokarczuk. Handke won the award "for an influential work that with linguistic ingenuity has explored the periphery and the specificity of human experience." Tokarczuk won the 2018 award "for a narrative imagination that with encyclopedic passion represents the crossing of boundaries as a form of life." Hide Caption

STOCKHOLM, Sweden - The Nobel Prize in Physics has been jointly awarded to James Peebles, Michel Mayor and Didier Queloz for their work in furthering our understanding of the universe. "This year's Nobel Prize in Physics rewards new understanding of the universe's structure and history, and the first discovery of a planet orbiting a solar-type star outside our solar system," tweeted the Nobel committee. Half of the 9 million Swedish krona ($910,000) prize will be given to Peebles, while Mayor and Queloz will split the rest. Peebles, who is Albert Einstein Professor of Science at Princeton University, had a message for budding scientists. In 2018 the Nobel Prize in Physics was awarded to a woman for the first time in 55 years, and for only the third time in its history.
