Photo by Xinhua News Agency reporter Ou Dongqu Supporting the world's largest and most sensitive Single-aperture radio telescope No experience to follow Facing unprecedented challenges Scientists of the "China Sky Eye" rely on The tenacity of “holding on to the green mountains and not letting go” The fighting spirit of “never return until Loulan is conquered” The spirit of “flattening the bumps and making a road” Constantly challenge the limits of cognition and technology Continuously expanding the boundaries of human observation of the universe On August 25, 2022, Jiang Peng (back), executive deputy director and chief engineer of the FAST Operation and Development Center, talked with staff in the control room of the "China Sky Eye" (photographed during maintenance). Xinhua News Agency reporter Ou Dongqu Since October 2019 FAST's annual observation time is stable at around 5,300 hours Telescope performance is also constantly improving Sky survey efficiency increased by an order of magnitude More than 800 new pulsars discovered It is the first observation equipment of the same type abroad in the same period More than three times the total number of pulsars discovered Become the most efficient pulsar searcher in the world Radio telescope Scientific research papers based on FAST results in the past three years About 150 articles Panoramic view of the "China Sky Eye" (taken during maintenance).
