One half of thePrize was awarded to James Peebles for “theoretical discoveriesin physical cosmology” and the other half jointly to MichelMayor and Didier Queloz for “the discovery of an exoplanetorbiting a solar-type star”. These are related to some of themost fundamental questions, namely the structure, constitutionand evolution of the Universe and the formation of planetsand the origin of life itself.
