Giant Telescopes of Tomorrow
Large Synoptic Survey Telescope
The LSST differs from the other ground-based optical telescopes in that it will have a wide field of view and will be able to move quickly between different areas of sky. Using the world's largest digital camera (3,200 megapixels), the LSST will do brief exposures of 10 to 20 seconds each. This will be ideal for investigating events too short-lived to be readily studied today, such as the trajectories of asteroids that might pose a threat to Earth. And by imaging the entire night sky every few nights, the LSST will offer, after about a decade of operation, the first "movie" of the universe.
