The world’s largest radio telescope has begun searching for signals from stars and galaxies and, perhaps, extraterrestrial life in a project demonstrating China’s rising ambitions in space and its pursuit of scientific prestige.
Beijing has poured billions into these scientific projects as well as its military-backed space program, including the launch of its second space station earlier this month.
The radio telescope, measuring 1,640ft in diameter, is nestled within a stunning landscape of karst formations in southern Guizhou province.
It took 5 years and around £140 million to complete, and surpasses the capability of the 985ft Arecibo Observatory in Puerto Rico, a dish used in research on stars which led to a Nobel Prize.
China’s official Xinhua News Agency said hundreds of astronomers and enthusiasts watched the launch of the Five-hundred-metre Aperture Spherical Telescope, or FAST.
Researchers said FAST would search for gravitational waves, detect radio emissions from stars and galaxies and listen for signs of intelligent extraterrestrial life.
“The ultimate goal of FAST is to discover the laws of the development of the universe,’ said Qian Lei, an associate researcher with the National Astronomical Observatories of the Chinese Academy of Sciences. In theory, if there is civilization in outer space, the radio signal it sends will be similar to the signal we can receive when a pulsar (spinning neutron star) is approaching us.”
