古往今来多少年,科学家只能从光学波段这一狭窄的“窗口”,仰视星象。地面天文观测的历史已经绵延了几千年,只是在空间技术迅速发展起来以后,才把地球大气外层的天文观测推向新的阶段。过去的十多年,天文学家已经依靠着各种空间探测器,将观测波段扩展到 X射线区和紫外区,完成了一些有意义的发现。但是,这些空间望远镜的孔径都没有超过一米级的,分辨率和观测距离受到孔径大小的 How many years have passed since ancient times, scientists can only look at the stars from the narrow “window” of the optical band. The history of terrestrial astronomical observations has lasted for thousands of years. Only after the rapid development of space technology has the astrometry of the outer layers of the Earth’s atmosphere been pushed to a new stage. For more than a decade, astronomers have relied on space probes to extend the observation band into the X-ray and ultraviolet regions, completing some meaningful discoveries. However, the aperture of these space telescopes is no more than one meter, the resolution and observation distance by the aperture size
