中国天眼（FAST）——位于贵州省的500米口径球面射电望远镜，是目前世界上最大、最灵敏的单口径射电望远镜。近日，中国科学院宣布，FAST即将迎来一次重大技术升级，旨在进一步提升其观测能力与科研效率。此次升级将重点优化接收机系统、数据处理平台和观测调度算法，使望远镜在脉冲星探测、中性氢巡天以及搜寻地外文明（SETI）等前沿领域发挥更大作用。例如，新型多波束接收机将显著提高观测覆盖范围和灵敏度，而人工智能驱动的数据处理系统则能更高效地识别和分析宇宙信号。自2016年启用以来，FAST已发现超过900颗新脉冲星，为天文学研究提供了宝贵数据。此次升级预计将在未来几年内完成，有望推动中国在射电天文学领域的国际领先地位，并为人类探索宇宙奥秘提供更强有力的工具。
China’s ‘Sky Eye’—the Five-hundred-meter Aperture Spherical radio Telescope (FAST), located in Guizhou Province—is currently the world’s largest and most sensitive single-dish radio telescope. Recently, the Chinese Academy of Sciences announced that FAST is set to undergo a major technical upgrade aimed at significantly enhancing its observational capabilities and research efficiency. The upgrade will focus on optimizing the receiver systems, data processing platforms, and observation scheduling algorithms, enabling more powerful contributions in cutting-edge fields such as pulsar detection, neutral hydrogen sky surveys, and the search for extraterrestrial intelligence (SETI). For instance, new multi-beam receivers will greatly expand observational coverage and sensitivity, while AI-driven data processing systems will enable faster and more accurate identification of cosmic signals. Since its commissioning in 2016, FAST has discovered over 900 new pulsars, providing invaluable data for astronomical research. The upgrade is expected to be completed within the next few years, further solidifying China’s leading role in radio astronomy and offering humanity a more powerful tool to explore the mysteries of the universe.
