We talk with Travis Metcalfe, of Boulder’s Space Science Institute, where he is searching for Sister Earth and also part of the Blue Dot Project. As for why, the past two decades have witnessed accelerating progress on one of the most fundamental questions in astronomy: Are we alone in the Universe? Astronomers have already discovered hundreds of planets around distant stars. Some of them are nearly as small as the Earth, and orbit in the “Goldilocks zone” of their parent star where liquid water can exist.
We congratulate Boulder’s David J. Wineland for winning the 2012 Nobel Prize in physics. Wineland, a physicist at the National Institute of Standards and Technology and CU-Boulder, shares the prize with and Serge Haroche of France. They are credited with making breakthroughs in quantum physics by showing how to observe individual quantum particles without destroying them. These, in turn, are the first steps toward building superfast computers based on quantum physics.
