STOCKHOLM — A Canadian American cosmologist and two Swiss scientists won this year’s Nobel Prize in Physics on Tuesday for exploring the evolution of the universe and discovering a new kind of planet, with implications for that nagging question: Does life exist only on Earth?
Canadian-born James Peebles, 84, an emeritus professor at Princeton University, won for his theoretical discoveries in cosmology. Swiss star-gazers Michel Mayor, 77, and Didier Queloz, 53, both of the University of Geneva, were honored for finding an exoplanet — a planet outside our solar system — that orbits a sun-like star, the Nobel committee said.
“This year’s Nobel laureates in physics have painted a picture of the universe far stranger and more wonderful than we ever could have imagined,” said Ulf Danielsson of the Royal Swedish Academy of Sciences, which selected the laureates. “Our view of our place in the universe will never be the same again.”
Peebles, hailed as one of the most influential cosmologists of his time who realized the importance of the cosmic radiation background born of the Big Bang, will collect one half of the 9-million kronor ($918,000) cash award. Mayor, who is an astrophysicist, and Queloz, an astronomer who is also at the University of Cambridge in Britain, will share the other half.
