Symmetry (Feb. 19) -- The Large Synoptic Survey Telescope, scheduled to come online in the early 2020s, will use a 3.2-gigapixel camera to photograph a giant swath of the heavens. It’ll keep it up for 10 years, every night with a clear sky, creating the world’s largest astronomical stop-motion movie. This type of data stream can be handled only with high-performance computing, the kind available at the National Center for Supercomputing Applications at the U. of I. – a long way from the remote Chilean mountaintop where the telescope will sit.
