Nobel prize in physics awarded for research on cosmology and exoplanets

"We can be very sure that as we discover new aspects of the expanding and evolving universe, we will be startled and amazed once again". Since then the universe has been expanding, becoming larger and colder and it was barely 400,000 years after the Big Bang that it became transparent and light rays were able to travel through space.

Among the Nobels, physics has often taken centre stage with winners featuring some of the greatest names in the history of science such as Albert Einstein, Marie Curie and Niels Bohr, as well as inventors such as radio pioneer Guglielmo Marconi. "Some of it will go to our children".

Peebles was awarded half the prize while Mayor and Queloz shared the other half.

An exoplanet is a planet outside the solar system.

"Recently, earth-like planets with the possibility to host life have been discovered".

"One of my earliest memories is throwing a tantrum because I was not allowed to get into the coffee percolator", he said.

The Swiss astronomer, jointly with his colleague Michael Mayor, discovered the first-ever extra-solar planet, 51 Pegasi b, unofficially dubbed Bellerophon and later formally named Dimidium, on 6 October 1995.

Hansson said he hoped fans of the show liked how this year's Nobel Prizes are handled. In the decades since, scientists have detected thousands more of these exoplanets, and astronomers now think our universe contains more planets than stars. He thought it was joke at first.

'I might barely breathe, ' Queloz mentioned. "It's enormous. It's beyond usual emotions". My hand used to be shaking for a truly very long time. I'm attempting to digest it'.

Their work centres on the hypoxic response - the way the body reacts to oxygen flux - and "revealed the elegant mechanisms by which our cells sense oxygen levels and respond", said Dr Andrew Murray, an expert at Britain's University of Cambridge, who congratulated the three.

"No", he said, "that's never come to my mind".

"My advice is not to aim for prizes and awards", he said.

That can't quite be said for Peebles' theoretical work. That search could one day answer the question of whether life exists elsewhere in the universe. His theoretical tools assisted science in understanding the dark components of our Universe better.

A clearly delighted Peebles giggled repeatedly during a phone interview with The Associated Press, recalling how he answered a 5.30 am local time phone call from Stockholm thinking that "it's either something very wonderful or it's something awful". "Since the discovery 25 years ago, everyone kept telling me: "It's a Nobel Prize discovery". "I can't forgive him for not showing up to the scene of (his) Nobel prize".

The academy says Peebles' theories form the basis of our contemporary ideas about the universe. Referencing its theme song therefore seemed fitting, he said.

The prize amount is 9 million Swedish kroner, or about $908,280, with Peebles receiving half of the award.
