A Canadian-American cosmologist and the two swiss scientists won Nobel Prizes in Physics for their work in understanding how the universe has advanced from the Big Bang and the blockbuster discovery of the first identified planet outside our solar system.
Canadian-born James Peebles, of Princeton College, was credited for “theoretical discoveries in physical cosmology” and Switzerland’s Michel Mayor, and Didier Queloz, each from the University of Geneva, were honored for discovering “an exoplanet orbiting a solar-type star,” stated Prof. Goran Hansson, secretary-general of the Swedish Academy of Sciences. The Nobel committee mentioned Peebles’ theoretical framework about the cosmos and its billions of galaxies and galaxy clusters amounted to “the muse of our fashionable understanding of the universe’s historical past, and from the Big Bang to now.”
The work set the stage for a transformation of the cosmology over the last half-century using theoretical tools and calculations that helped to interpret traces from the infancy of the universe, the committee stated. Peebles is the Professor of Science at Princeton.Mayor and Queloz have been credited having “began a revolution in astronomy,” notably with the discovery of exoplanet Pegasi B, a gaseous ball comparable with Jupiter, in 1995 a time when, as Mayor recalled — that “nobody knew whether exoplanets existed or not.”
An exoplanet is a planet outdoors in the solar system.”Prestigious astronomers had been looking for them for years, in useless!”More than 4,000 planets have since been discovered in the Milky Way since then, and “Unusual new worlds are still being found, with an incredible wealth of sizes, forms, and orbits,” the committee said.
The University of Geneva quoted to the Mayor and Queloz as saying it was “simply extraordinary” that they gained the prize for “the most exciting” discovery of their careers.
