The Large Synoptic Survey Telescope (LSST) project is a giant survey telescope that will be located in Chile and is designed to make a three
dimensional survey of the entire visible sky. The LSST Dark Energy Science Collaboration will examine billions of galaxies and try to determine the nature of the mysterious “Dark Energy” which is unaccountably causing the universe to be pushed apart at a faster and faster rate.

The LSST will open a whole new field of observational cosmology by collecting an unprecedented amount of data and addressing some of the most fundamental questions we have about space-time including the nature of gravity, dark energy, dark matter and inflation. In 2010 a panel convened by the National Research Council for the National Academy of Sciences ranked LSST as its top priority for the next large ground-based astronomical facility. LSST will survey the entire visible sky with a level detail and distance that has never been achieved before
