摘要

The National Astronomical Observatories (NAOC) has started building the largest antenna in the world. Known as FAST, the Five-hundred-meter Aperture Spherical radio Telescope is a Chinese mega-science project funded by the National Development and Reform Commission (NDRC). FAST also represents part of Chinese contribution to the international efforts to build the square kilometer array (SKA). Upon its finishing around September of 2016, FAST will be the most sensitive telescope in the low frequency radio bands between 70 MHz and 3 GHz. FAST has the potential to make significant discoveries in the fields of astrophysics and astrochemistry, such as gaseous universe, star formation, compact objects, gravitational waves, and cosmology. I will give a brief overview of the project and its key science goals. The rest of the talk will be devoted to the "early science" opportunities of FAST.
