Primeval Structure Telescope, Radio telescope in Ulastai, China
The Primeval Structure Telescope is a radio telescope in Xinjiang equipped with ten thousand log-periodic antennas positioned at 2500 meters elevation on the Ulastai plateau. The antenna array spans several kilometers and was specifically designed to observe hydrogen emissions from the early universe.
Construction began in 2004 under the National Astronomical Observatory of China to detect signals from the earliest luminous objects in the universe. This marked a major step forward in Chinese radio astronomy and research into the cosmic early universe.
Chinese scientists and international researchers collaborate at this facility to study neutral hydrogen emissions and understand fundamental cosmic processes through radio astronomy.
The remote plateau location minimizes interference from television and radio signals, allowing clear observations of distant celestial objects. Visitors should be prepared for the high altitude and rugged terrain when planning their visit.
The facility observes at the precise hydrogen line frequency, which is ideal for studying structures from the early universe. This specific wavelength was chosen because hydrogen is the most abundant element in the cosmos and carries light from that distant era.
