Help build the "New Sky" .

The Large Synoptic Survey Telescope (LSST) is a proposed large aperture, ground-based, wide field survey telescope designed to provide digital images of faint astronomical objects across the entire sky, night after night. It will have an 8.4-meter primary mirror with effective collecting area equivalent to a 6.7-m diameter unobstructed primary and a field of view of 10 square-degrees. In a relentless campaign of 15 second exposures with its 3.2 Giga pixel camera, the LSST will cover the available sky every three nights, opening a movie-like window on objects that change or move on rapid timescales: exploding supernovae, potentially hazardous near-Earth asteroids, and distant Kuiper Belt Objects. The superb images from the LSST will also be used to trace billions of remote galaxies and measure the distortions in their shapes produced by lumps of Dark Matter, providing multiple tests of the mysterious Dark Energy.
