Five-hundred-meter Aperture Spherical radio Telescope


Being the world’s largest filled-aperture telescope located at an extremely radio quiet site, the FAST science impact on astronomy will be extraordinary, and has the potential to revolutionize other areas of the natural sciences. Compared with its precursor — Arecibo — FAST has an advantage of a factor of 2 in raw sensitivity and a factor of 5-10 in surveying speed. FAST will also cover two to three times more sky area thanks to its innovative design of an active primary surface. A science instrument with an order of magnitude improvement in any of its capacities which is also able to explore new dimensions in parameter space is likely to generate unexpected discoveries.
