China’s Giant Radio Telescope Begins Searching For Signals From Space

Years of work and millions of dollars later, China finished its alien-hunting telescope in May this year. Now the country says its telescope has begun its operation. The company flipped the switch over the weekend, hoping to find signals from stars and galaxies — and more importantly from extraterrestrial life. The telescope also illustrates China’s growing ambition to stay among the frontrunners in space efforts. AP reports: Beijing has poured billions into such ambitious scientific projects as well as its military-backed space program, which saw the launch of China’s second space station earlier this month. Measuring 500 metres in diameter, the radio telescope is nestled in a natural basin within a stunning landscape of lush green karst formations in southern Guizhou province. It took five years and $180 million to complete and surpasses that of the 300-meter Arecibo Observatory in Puerto Rico, a dish used in research on stars that led to a Nobel Prize. The official Xinhua News Agency said hundreds of astronomers and enthusiasts watched the launch of the Five-hundred-meter Aperture Spherical Telescope, or FAST, in the county of Pingtang. Researchers quoted by state media 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,” Qian Lei, an associate researcher with the National Astronomical Observatories of the Chinese Academy of Sciences, told state broadcaster CCTV. “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,” Qian said.
