Three win 2011 physics Nobel for universe expansion work

STOCKHOLM - Three scientists shared the 2011 Nobel Prize for physics for the discovery of the accelerating expansion of the universe through observations of exploding stars, the prize committee said on Tuesday.
One half of the 10 million Swedish crowns ($1.45 million) went to US citizen Saul Perlmutter and the other half to US-Australian citizen Brian Schmidt and US scientist Adam Riess.
"They have studied several dozen exploding stars, called supernovae, and discovered that the universe is expanding at an ever-accelerating rate," prize said the Nobel Committee for Physics at the Royal Swedish Academy of Sciences, which awards the prize.
"The discovery came as a complete surprise, even to the laureates themselves," the committee added in a statement.
