The Nancy Grace Roman Space Telescope’s primary mirror, which will collect and focus light from cosmic objects near and far, has been completed. Using this mirror, Roman will capture stunning space vistas with a field of view 100 times greater than Hubble images.

Roman will peer through dust and across vast stretches of space and time to study the universe using infrared light, which human eyes can’t see. The amount of detail these observations will reveal is directly related to the size of the telescope’s mirror, since a larger surface gathers more light and measures finer features.

南茜·格蕾丝·罗曼太空望远镜的主镜已经完成,它将收集和聚焦远近宇宙物体的光线。利用这面镜子,罗曼太空望远镜将以比哈勃望远镜大100倍的视野捕捉令人惊叹的太空景象。

罗曼太空望远镜将透过尘埃和广阔的空间和时间,利用人眼看不到的红外光研究宇宙。这些观察结果所揭示的细节数量与望远镜镜面的大小直接相关,因为较大的镜面能收集更多的光线,并能测量出更精细的特征。
