The world's largest fully steerable radio telescope is being built in China's Xinjiang Uyghur Autonomous Region. Located in Xinjiang's Qitai county, the Qitai radio telescope (QTT) will have a steerable dish antenna with a diameter of 110 meters.
The diameter of the QTT will be 10 percent larger than the Green Bank Telescope in the US state of West Virginia, the world's largest steerable radio telescope. Expected to take 6 years to build, QTT will cover 75 percent of the sky with high precision, providing a world-class observing platform for studies in areas such as black holes, quasars, fast radio bursts, dark matter, gravitational waves and the origins of life in the universe.
The world's largest radio telescope, the 500-meter Aperture Spherical Radio Telescope (FAST), is also located in the Guizhou province of China.
