The Five-hundred-meter Aperture Spherical（口径球面）radio Telescope（FAST），nicknamed Tianyan，“Heavenly Eye” or “The Eye of Heaven”， is a radio telescope located in the Dawodang Depression （大窝凼洼地）.

1.______Itconsistsof a fixed 500m diameter dish constructed in a natural depression in the landscape.It is the world's largest filled-aperture radio telescope.

Construction on the FAST project began in 2011 and was completed in September 2016.2.________Astronomersare able to useFAST to survey hydrogen in the Milky Way（银河系） and other galaxies and study the origin and evolution of the universe.

Over 2，700 pulsars（脉冲星）have been identified since the first one was discovered by British astronomers Jocelyn Bell Burnell and Antony Hewish on Nov.28，1967.3_______._Many scientists expect FAST to be the first telescope to capture a pulsar outside the galaxy.Technical preparations have been made for FAST tosearch forpulsars outside the Milky Way.

4._______Engineers have said it issosensitivethatit could capture the signal of a cell phone being used on the moon.After one year of trial operation，FAST has discovered 11 new pulsars so far.

FAST is expected to discover twice the number of pulsars currently known and itishighlylikely to makebreakthroughs in the study of gravitational waves and general relativity theory.5.__________.
