Three scientists won the 2019 Nobel Prize in Physics on Tuesday for their work in understanding how the universe has evolved, and the Earth's place in it.
The prize was given 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," said 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."
