Stockholm, October 8: The 2019 Nobel Prize in Physics has been awarded on Tuesday to James Peebles, Michel Mayor and Didier Queloz. One half of the Nobel Prize is awarded to James Peebles “for theoretical discoveries in physical cosmology” and the other half will be jointly shared by Michel Mayor and Didier Queloz “for the discovery of an exoplanet orbiting a solar-type star.” The award ceremony was held at Stockholm in Sweden. Nobel Prize 2018 For Physics Winner: Arthur Ashkin, Gerard Mourou & Donna Strickland Awarded Honour For Laser Inventions.

The Nobel Prize academy tweeted, “The 2019 #NobelPrize in Physics has been awarded with one half 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.”

All You Need to Know About the Winners of 2019 Nobel Prize in Physics:

James Peebles:

James Pebbles is a Canadian-American physicist and theoretical cosmologist who is currently the Albert Einstein Professor Emeritus of Science at Princeton University. Peebles has made many important contributions to the Big Bang model. Apart from Nobel Prize, he also received Harvey Prize in 2001, Dirac Medal in 2013 and Member of the Order of Manitoba in 2017.

Michel Mayor:

Michel G.E. Mayor is a Swiss astrophysicist and professor emeritus at the University of Geneva's Department of Astronomy. Mayor formally retired in 2007, but remains active as a researcher at the Observatory of Geneva. He is also co-winner of the 2010 Viktor Ambartsumian International Prize, and the winner of the 2015 Kyoto Prize.

Didier Queloz

Didier Queloz  is a Swiss astronomer with a prolific record in finding extrasolar planets in the Astrophysics Group of the Cavendish Laboratory, Cambridge, and also at the University of Geneva. Queloz performed an analysis on 51 Pegasi using radial velocity measurements (Doppler spectroscopy), and was astonished to find a planet with an orbital period of 4.2 days.

On Monday, the 2019 Nobel Prize for Medicine has been jointly awarded to William G. Kaelin Jr, Sir Peter J. Ratcliffe and Gregg L. Semenza for their discoveries of how cells sense and adapt to oxygen availability. The jury stated that the three researchers established the basis for the understanding of humans of how oxygen levels affect cellular metabolism and physiological function.

Alfred Nobel — a Swedish industrialist and the inventor of dynamite —founded the Nobel Prize. Nobel Prize for physics, chemistry, medicine and literature prizes are awarded in Stockholm, while the peace prizes are given in Oslo.
