    Stockholm (dpa) - The Nobel Prize for Physics this year goes to James Peebles (Canada / USA) as well as to Michel Mayor (Switzerland) and Didier Queloz (Switzerland) for their contributions to the understanding of the universe and the Earth's place in the world Cosmos. This was announced by the Royal Swedish Academy of Sciences in Stockholm on Tuesday.

    Stockholm (dpa) - Der Nobelpreis für Physik geht in diesem Jahr jeweils zur Hälfte an James Peebles (Kanada/USA) sowie an Michel Mayor (Schweiz) und Didier Queloz (Schweiz) für ihre Beiträge zum Verständnis des Universums und des Platzes der Erde im Kosmos. Das teilte die Königlich-Schwedische Akademie der Wissenschaften am Dienstag in Stockholm mit.

    Just going to piggyback and paste an excerpt from an article explaining what they won the award for.

    "Peebles helped predict the cosmic microwave background radiation—the first light in the universe, which allows scientists to trace the earliest epochs in the cosmos. Over a half-century career he has shaped our view of how the big bang created matter, how galaxies formed and what makes up the missing bulk of the universe—the unknown entities of dark matter and dark energy. “Isn’t it fascinating,” Peebles said this morning during a Nobel announcement interview, “that we have very clear evidence that our universe did expand from a hot, dense state, but although the theory is very thoroughly tested, we still must admit that the dark matter and dark energy are mysterious?”


    The other side of the prize this year honors one of the pioneering discoveries in exoplanet science: the 1995 revelation of 51 Pegasi b. Mayor and Queloz carefully measured a star’s velocity, finding that it wobbles back and forth in a telltale pattern produced by the gravitational pull of an orbiting planet.


    Before this finding, the only confirmed exoplanet known orbited a pulsar—a dense remnant from a supernova explosion. The world 51 Pegasi b, on the other hand, orbits a “main sequence” star, the same category as our sun, about 50 light-years from Earth. It was the prototype “hot Jupiter”—a massive gas giant around the size of the solar system’s largest planet (in this case about half the mass of our own Jupiter) in a bizarrely short orbit extremely close to its star. The planet has a year only four days long. “Few had expected that such planets could exist,” Danielsson said. “We had thought that other solar systems would be similar to our own. We were wrong!” The discovery launched a race that has now racked up more than 4,000 known planets orbiting other stars."
