Accra, Oct. 8, (UPI/GNA) - The Nobel Prize in Physics for 2019 on Tuesday was awarded to three
scientists for their focus on the cosmos and the discovery of a new planet
outside the solar system.
The prize was
given to James Peebles for his "theoretical discoveries in physical
cosmology" and Michael Mayor and Didier Queloz "for the discovery of
an exoplanet orbiting a solar-type star."
laureates represent "ground-breaking discoveries" in the field of
science and astronomy, said Mats Larsson, professor of molecular physics and
chair of the Nobel Committee for Physics.

understanding of the dark components of the universe, which have been around
since the Big Bang.

into a science of precision," Larsson said.
years after his discovery, Peebles said there are still many questions
remaining about dark matter and the role it plays in expanding the universe.

In 1995, Mayor
and Queloz discovered the first exoplanet, 51 Pegasi b, and while at the
Haute-Provence Observatory in southern France.
