“中国天眼”要升级了！这座位于贵州省平塘县的500米口径球面射电望远镜（FAST），是目前世界上最大、最灵敏的单口径射电望远镜。自2016年建成以来，FAST已在脉冲星发现、快速射电暴研究、中性氢观测等多个前沿领域取得突破性成果。近日，中国科学院宣布将对FAST进行新一轮技术升级，重点提升其接收机系统、数据处理能力和观测效率。升级后，FAST将具备更宽的观测频段、更高的时间与频率分辨率，有望捕捉到更多宇宙深处的微弱信号，包括可能来自地外文明的线索。此外，升级还将增强其多目标同时观测能力，使其在探索宇宙起源、暗物质分布和引力波等方面发挥更大作用。此次升级不仅标志着中国在天文观测领域的持续投入，也彰显了FAST作为全球科研基础设施的重要地位。未来，FAST将继续向国际科学界开放合作，为人类探索宇宙奥秘贡献中国力量。
China’s ‘Sky Eye’ is getting an upgrade! The Five-hundred-meter Aperture Spherical radio Telescope (FAST), located in Pingtang County, Guizhou Province, is currently the world’s largest and most sensitive single-dish radio telescope. Since its completion in 2016, FAST has made groundbreaking discoveries in areas such as pulsar detection, fast radio bursts, and neutral hydrogen mapping. Recently, the Chinese Academy of Sciences announced a new round of technical upgrades focused on enhancing its receiver systems, data processing capabilities, and observational efficiency. After the upgrade, FAST will operate across a broader frequency range with higher time and frequency resolution, enabling it to detect even fainter signals from deep space—including potential signs of extraterrestrial intelligence. The improvements will also allow simultaneous observation of multiple targets, significantly boosting its role in studying cosmic origins, dark matter distribution, and gravitational waves. This upgrade underscores China’s ongoing commitment to astronomical research and reinforces FAST’s status as a vital global scientific infrastructure. Moving forward, FAST will continue to welcome international collaboration, contributing Chinese expertise to humanity’s quest to unravel the mysteries of the universe.
