Jan. 27: An Enormous Picture of the Universe John Schaefer, UA President Emeritus and President of the LSST Corp., will talk about the Large Synoptic Survey Telescopes, or LSST. Now under construction, the LSST will be the world's largest, most powerful wide-angle survey telescope when it starts operating in 2015. It will provide time-lapse digital imaging across the entire available night sky every three days, enabling astronomers anywhere simultaneous access to study supernovae, planet-approaching asteroids or comets and other dynamic celestial chance events, and explore the nature of dark matter and dark energy.
