SHANGHAI, Feb.1 (Xinhua) -- East Asian astronomers are building the world's largest radio telescope array to see the deep into the galaxy and black holes and more accurately determine the orbits of lunar probes such as China's Chang'e-1.
The array, called the East Asia Very Long Baseline Interferometry (VLBI) consortium, consists of 19 radio telescopes from China, Japan and the Republic of Korea (ROK) that cover an area with a diameter of 6,000 kilometers from northern Japan's Hokkaido to western China's Kunming and Urumqi.
The VLBI technology is widely used in radio astronomy. It combines the observations simultaneously made by several telescopes to expand the diameter and increase magnification.
