Press conferences in Europe and the U.S. this morning announced the first cosmological results of the Planck mission to map the cosmic microwave background at the highest level of detail ever achieved. The new data reveal a universe that is accelerating but is older and expanding more slowly than previously thought. It also contains more matter and less dark energy. Berkeley Lab physicists and computer scientists have played a major role in Planck.
