China opens gigantic telescope to hunt life beyond earth


China on Saturday officially opened operations of the world’s largest radio telescope, which it will use for space research and in the hunt for extraterrestrial life. The 500m Aperture Spherical Telescope, or Fast, is the size of 30 football fields and has been hew out of a mountain in the south-western province of Guizhou. It is also known by the name “Sky Eye” in China.
Xinhua reported that the telescope had received national approval to start operations. It finished construction in 2016 and has been undergoing debugging and tests in the years since. Chief Engineer Jiang Peng told Xinhua that the telescope’s trial operations had been reliable and stable, and that its sensitivity was more than 2.5 times that of the world’s second-largest telescope.
The project has also obtained some valuable scientific data over that time and is expected to help lead to some breakthroughs in areas such as low-frequency gravitational wave detection and interstellar molecules in the next three to five years. Advancing China’s space programme is a priority for Beijing, and the country has set a target to catch up with Russia and the United States and become a major space power by 2030.
