Qitai Station
The Qitai Station is located in the Eastern Tianshan Mountains, 46 kilometers in a straight line from Qitai County in the Changji Hui Autonomous Prefecture of Xinjiang, at an elevation of approximately 1800 meters.
The site's environment features a dry climate and minimal rainfall, resulting in low annual integrated atmospheric water vapor content. These geographical advantages make Qitai Station one of the best radio astronomy observation sites in the world.
The QiTai radio Telescope (QTT) is under construction at the Qitai Station. The QTT is a fully steerable Gregorian-type telescope with a standard parabolic main reflector of hundred-meter-level diameter. The telescope will form a world-class observational platform for the detection of nanohertz gravitational waves through pulsar timing array (PTA), pulsar surveys, the discovery of binary black-hole systems, and exploring dark matter and the origin of life in the universe. The QTT will also play an important role in improving the Chinese and international VLBI networks, allowing high-sensitivity and high-resolution observations of the nuclei of distant galaxies and gravitational lensing systems. The telescope will also contribute to deep space exploration by enhancing the precision of the celestial reference frame. Potentially, it will be able to support future space activities such as planetary exploration in the solar system and to contribute to the search for extraterrestrial intelligence.
The Qitai Station will serve as a comprehensive station that integrates experimental facilities, scientific research, observational activities, and residential spaces. It will also become the largest astronomical science popularization education base in northwest China. This station will provide students from primary school to university with a venue that combines scientific practice, science outreach, and outdoor activities, offering a wide spectrum of diverse and enriching learning opportunities.
