China's FAST

精彩導讀

“中國天眼”位于貴州省黔南市，具有我國自主知識產(chǎn)權(quán)。專家稱“中國天眼”足足領(lǐng)先世界10到20年。通過500米口徑球面射電望遠鏡，我國對暗物質(zhì)以及暗物質(zhì)的變化規(guī)律、脈沖星以及來自其他星體的生命信號進行勘探，甚至能夠研討生命的來源和宇宙的演變，這對我國航空航天的技術(shù)發(fā)展有著重要意義。

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

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（銀河系） and other galaxies and study the origin and evolution of the universe.

Over 2，700 pulsars（脈沖星）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，F(xiàn)AST 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.__________.
