b. Puerto Rico
c. USA
d. China

ANSWER: China
 
  • It is in Guizhou, China
  • Five-hundred-meter Aperture Spherical Telescope's (FAST) is by far the largest single-aperture telescope in the world (though arrays that link up multiple radio dishes cover more ground). The previous record holder in the field is the 1,000-foot-wide (300 meters) Arecibo Observatory in Puerto Rico.
  • FAST is the world's largest and most sensitive radio telescope and three times more sensitive than the Arecibo Observatory. Operates at 300 MHz to 5.1 GHz.
  • The facility should help scientists learn more about the universe's early days, detect low-frequency gravitational waves and hunt for signals that may have been produced by distant alien civilizations.
