The 2019 Nobel Prize in Physics was awarded Tuesday to three scientists for their contribution to the understanding of the evolution of the universe. The award was shared between the three with one half going to James Peebles “for theoretical discoveries in physical cosmology” and the other half jointly to Michel Mayor and Didier Queloz “for the discovery of an exoplanet orbiting a solar-type star.”

The award was announced by Prof. Goran Hansson, secretary-general of the Royal Swedish Academy of Sciences that chooses the laureates.

An exoplanet is a planet outside the solar system. Hansson credited the three for their "contributions to our understanding of the evolution of the universe, and Earth's place in the cosmos," news agency AP reported.

The prize comes with a 9-million kronor (USD 918,000) cash award to be shared a gold medal and a diploma. The laureates receive them at an elegant ceremony in Stockholm on December 10, the anniversary of the death of prize founder Alfred Nobel in 1896, together with five other Nobel winners. The sixth one, the peace prize, is handed out in Oslo, Norway on the same day.

This was the 113th Nobel Prize in Physics awarded since 1901, of which 47 awards have been given to a single laureate. Only three women have been awarded it so far: Marie Curie in 1903, Maria Goeppert-Mayer in 1963 and Donna Strickland in 2018, according to the Nobel website.

This year, the Nobel Prizes are being announced between October 7 and 14, in the following order: October 7 (Medicine), October 8 (Physics), October 9 (Chemistry), October 10 (Literature), October 11 (Peace), October 14 (Economics).

On Monday, Americans William G Kaelin Jr and Gregg L Semenza and Britain's Peter J Ratcliffe won the Nobel prize for Physiology or Medicine, for discovering details of how the body's cells sense and react to low oxygen levels, providing a foothold for developing new treatments for anemia, cancer and other diseases.

Events began Monday with the award announcement for Physiology or Medicine. The Chemistry prize will be announced on Wednesday. This year’s double-header Literature Prizes will be awarded Thursday and the Peace Prize will be announced on Friday. The economics prize will be awarded in the last — on October 14.

The 2018 literature prize was suspended after a scandal rocked the Swedish Academy. The body plans to award it this year, along with announcing the 2019 laureate.
