China to set up gravitational wave telescopes in Tibet

China is working to set up the world's highest altitude gravitational wave telescopes in Tibet Autonomous Region to detect the faintest echoes resonating from the universe, which may reveal more about the Big Bang.

Construction has started for the first telescope, code-named Ngari No.1, 30 km south of Shiquanhe Town in Ngari Prefecture, said Yao Yongqiang, chief researcher with the National Astronomical Observatories of the Chinese Academy of Sciences.

The telescope, located 5,250 meters above sea level, will detect and gather precise data on primordial gravitational waves in the Northern Hemisphere. It is expected to be operational by 2021.

Yao said the second phase involves a series of telescopes, code-named Ngari No. 2, to be located about 6,000 meters above sea level. He did not give a time frame for construction of Ngari No. 2.

The budget for the two-phase Ngari gravitational wave observatory is an estimated 130 million yuan (US$18.8 million). The project was initiated by the Institute of High Energy Physics, National Astronomical Observatories, and Shanghai Institute of Microsystem and Information Technology, among others.

Ngari, with its high altitude, clear sky, and minimal human activity, is said to be one of the world's best spots to detect tiny twists in cosmic light.
