The Large Synoptic Survey Telescope (LSST) is a 8 meter class telescope with a 3.2 Gigapixel camera covering 10 deg² . It will see its first light in 2020. LSST will perform a survey of the sky, allowing over 6 bands to screen ~ ½ of the sky surface continuously. After 10 years, the survey of 18,000 deg² of the southern sky to 27th mag will include > 800 visits for each portion of the visited sky. The history of astronomy has taught us repeatedly that there are surprises whenever we view the sky in a new way. With an unprecedented combination of sky coverage, cadence, and depth, the LSST makes it possible to attack high-priority scientific questions that are far beyond the reach of any existing or planned facility. Some of LSST's science will rely on the statistical precision obtainable with billions of objects. For the first time, the sky will be surveyed deep and fast, opening a new window on a universe of faint moving and distant exploding objects. LSST is specifically designed to explore the physics of dark energy and dark matter.
In this seminar we will present the LSST project, including a short overview of the IN2P3 contribution and underline a few key scientific topics going from transient to dark energy and dark matter.
