February 1, 2012breaking: Calculating the universeSince 2000, the three Sloan Digital Sky Surveys (SDSS I, II, and III) have surveyed well over a quarter of the night sky, producing the biggest 3-D color map of the universe ever made. Now, scientists have used this visual information for the most accurate computation yet of how matter clumped together – from a time when the universe was only half its present age until now.

October 4, 2011breaking: Astronomers win Nobel Prize in Physics for discovering the accelerating expansion of the universeThe 2011 Nobel Prize in Physics has been awarded to three scientists: Saul Perlmutter, Brian Schmidt and Adam Riess. Their observations of distant exploding stars led them to the startling discovery that the expansion of the universe is accelerating. This discovery laid the groundwork for the idea that a mysterious force called dark energy, which makes up 75 percent of the universe – yet has never been detected – is fueling the acceleration
