Radio astronomers are now able to synthesize the response of a partially filled aperture of large diameter and thus to map variations in nebular brightness . 射电天文学家现在已经能够把部分充满的大直径孔径进行综合,从而描绘出星云亮度变化图。
Why can radio astronomers observe during the day , whereas optical astronomers are ( for the most part ) limited to nighttime observing 译文:为什么射电天文学家可以在白天观测,而光学天文学家的绝大多数观测只能在夜晚进行
