The LSST is a new kind of telescope. Currently under construction in Chile, it is being built to rapidly survey the night-time sky.
Compact and nimble, the LSST will move quickly between images, yet its large mirror and large field of view—almost 10 square degrees of sky, or 40 times the size of the full moon—work together to deliver more light from faint astronomical objects than any optical telescope in the world.
