Saul Perlmutter, winner of the Nobel Prize for physics, poses with his daughter's telescope at his home in Berkeley, Calif., Tuesday, Oct. 4, 2011 after hearing he had won. The Royal Swedish Academy of Sciences said American Perlmutter would share the 10 million kronor ($1.5 million) award with U.S.-Australian Brian Schmidt and U.S. 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 analyzing a particular type of supernovas, or exploding stars.
