NOBEL PRIZE 2011- Physics Prize honours ‘Expanding Universe’ find

Brian P. Schmidt,  Adam G. Riess,   Saul Perlmutter
Saul Perlmutter, Brian P. Schmidt and Adam G. Riess won the Nobel Prize in physics on Tuesday for their studies of exploding stars that revealed that the expansion of the universe is accelerating. The Royal Swedish Academy of Sciences said American Perlmutter would share the 10 million kronor ($1.5 million) award with American-Australian Brian Schmidt and American scientist Adam Riess. Working in two separate research teams during the 1990s - Perlmutter in one and Schmidt and Riess in the other - the scientists raced to map the universe's expansion by analysing a particular type of supernovas, or exploding stars. They found that the light emitted by more than 50 distant supernovas was weaker than expected, a sign that the universe was expanding at an accelerating rate, the academy said.

and Space Telescope Science Institute, 
Baltimore, MD, USA.

"For almost a century the universe has been known to be expanding as a consequence of the Big Bang about 14 billion years ago," the citation said. 
"However the discovery that this expansion is accelerating is astounding. If the expansion will continue to speed up the universe will end in ice." 
Prof Perlmutter led the Supernova Cosmology Project, which began in 1988, and Prof Schmidt and Prof Riess began work in 1994 on a similar project known as the High-z Supernova Search Team. Read more
