China has completed the installation of its 500-meter Aperture Spherical Telescope, known as FAST. It's the largest such radio telescope in the world. FAST lies at a karst valley in Pingtang County of southwest China's Guizhou Province. Scientists and reporters are gathering at the completion ceremony. The telescope was independently designed and built by China.
FAST's concept was initiated in 1994 and the construction took more than five years. Adjustment will take 2 to 3 years. Experts say FAST has the potential to search for remote objects to better understand the origin of the universe, and boost the global hunt for extraterrestrial life.
