Scientists generate thousands of simulations to analyze flood of data from the Planck mission

(Phys.org) —To make the most precise measurement yet of the cosmic microwave background (CMB) – the remnant radiation from the big bang – the European Space Agency's (ESA's) Planck satellite mission has been collecting trillions of observations of the sky since the summer of 2009. On March 21, 2013, ESA and NASA, a major partner in Planck, will release preliminary cosmology results based on Planck's first 15 months of data. The results have required the intense creative efforts of a large international collaboration, with significant participation by the U.S. Planck Team based at NASA's Jet Propulsion Laboratory (JPL).
