LSST stands for the Large Synoptic Survey Telescope, which is a telescope currently under construction in Chile. LSST is designed to conduct a wide and deep survey of the night sky, with the goal of mapping the entire visible universe every few nights. The telescope will be equipped with a 3.2-gigapixel camera, making it one of the largest digital cameras ever built. LSST will be used to study a variety of astrophysical phenomena, including dark matter, dark energy, supernovae, and potentially hazardous asteroids. Overall, LSST aims to revolutionize our understanding of the universe by providing unprecedented insights into its structure and evolution.
