The Large Synoptic Survey Telescope, is a ground-based telescope slated for construction on Cerro Pachón, a mountain in northern Chile. Construction on the telescope will last for 10 years and will produce 2,000 images of every part of the sky - more than 20,000 square degrees. LSST will produce 30 terabytes of data per night, yielding a total database of 100 petabytes. This massive data set will be used to construct, for the first time, a color "movie" of the sky that will enable unique and powerful studies of objects that move or change in brightness.

Upon completion, the LSST will be equipped with the world's largest digital camera, which will be used to survey the entire visible sky. These images can then be used to study the light-bending gravity of dark matter in an effort to chart the history of the expansion of the universe and probe the mysterious nature of dark energy. The LSST data will be open to the public and scientists around the world - anyone with a Web browser will be able to access the images and other data produced by the LSST.

Tony Tyson, professor at University of California Davis, was interviewed at the SPIE Astronomical Instrumentation meeting.
