3 scientists win Nobel for discoveries about universe
Three scientists have been awarded the 2019 Nobel Prize in Physics for "ground-breaking" discoveries about the Universe.
James Peebles, Michel Mayor and Didier Queloz were announced as this year's winners at a ceremony in Stockholm.
Peebles was honoured for work on the evolution of the Universe, while Mayor and Queloz won for their discovery of a planet around a Sun-like star.
The winners will share the prize money of nine million kronor (£738,000).
Winnipeg, Canada-born James Peebles was honoured for his contributions to the understanding of the evolution of the Universe and Earth's place in the cosmos.
With others, he predicted the existence of cosmic microwave background (CMB) radiation, the so-called afterglow of the Big Bang.
Michel Mayor and Didier Queloz were awarded the prize for finding 51 Pegasi b, a gas giant orbiting a star 50 light-years away.
