“中国天眼”正稳步推进升级规划 构建全球唯一巨型综合孔径阵列

Core Insights - The "China Sky Eye" (FAST) is advancing its upgrade plan to establish a unique giant integrated aperture array centered around the telescope, enhancing its observational capabilities and solidifying China's leadership in the field of radio astronomy [1][3]. Group 1: Upgrade and Innovation - The upgrade will involve the construction of dozens of medium-sized antennas around the 500-meter diameter FAST, addressing the limitations of single-dish telescopes in spatial resolution and significantly improving observational sensitivity [1][3]. - This innovative design aims to achieve a qualitative leap in comprehensive observational performance, reinforcing China's core position in the mid-low frequency radio astronomy sector amidst intense international competition [3]. Group 2: Scientific Contributions - Upon completion of the upgrades, FAST will serve as a more powerful "cosmic super probe," aiding scientists in understanding the origins of fast radio bursts and addressing long-standing astrophysical challenges such as the Hubble constant crisis and the missing baryonic matter problem [3][4]. - The telescope has already produced groundbreaking results in various fields, including gravitational wave detection, pulsar searches, and neutral hydrogen observations, significantly enhancing China's academic influence and international standing in radio astronomy [4]. Group 3: Strategic Importance - The achievements of the "China Sky Eye" reflect China's core capabilities in major scientific infrastructure, showcasing the country's ability to independently control key technologies and continuously lead in scientific output [4].
