Korean, Chinese and Japanese astronomers will join hands to make a 6,000 km-diameter radio telescope, the world's largest, China's official Xinhua news agency reported on Jan. 31.
Quoting Shen Zhiqiang, a researcher at the Shanghai Astronomical Observatory of the Chinese Academy of Science, Xinhua said the radio telescope network of the three countries will reach the Ogasawara Islands of Japan to the east, China's Xinjiang Uygur Autonomous Region to the west, and Kunming, China to the south.
The network will consist of 19 astronomical observatories in the three countries. Korea and Japan are building a special computer to operate the network, which will be installed in Seoul and begin operations late next year. The network will be set up to observe black holes and the structure of the galaxy.
Xinhua said the three countries can build a radio telescope measuring up to 24,000 km if their radio telescope network is combined with a satellite radio telescope that China and Japan have recently launched. Japan will use its galaxy observation technology, and China 20 to 50 m-tall antennas in Beijing, Shanghai and Kunming.
For the network, Korea has completed three radio telescopes, each 21 m in diameter, and Japan has built 12 new radio telescopes.
