China Builds World's Largest Radio Telescope

FAST was built in China's Guizhou
Province, more than 1,240 miles (2,000 kilometers) southwest of Beijing. The
1.2-billion-yuan ($180 million) 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,
project officials said.
