RADIO ASTRONOMY:
China Hopes to Move FAST on Largest Telescope
Li Hui
BEIJING--China has embarked on a project to build the world's largest radio telescope, a spherical dish 500 meters in diameter, in southwest Guizhou Province--a terrain of hundreds of round depressions, each surrounded by hills a few hundred meters high. The facility could make China a major player in the field. But Chinese scientists are hoping for even more: They see the telescope as the forerunner of a billion-dollar, internationally funded radio array that would probe the very earliest stages of the universe.
