Radio telescopes have been able to probe space beyond the range of ordinary optical telescopes 射电望远镜已能探测普通光学望远镜达不到的宇宙空间
But even the best optical telescopes cannot make out what the universe was like at an age of less than one billion years 但即便是最先进的光学望远镜,也无法窥知宇宙在10亿岁之前的模样。
Regarding groundbased observation , the largest optical telescopes to date are the twin 10 - m keck telescopes on mauna kea of hawaii 位于夏威夷蒙那基亚山上的却克望远镜,口径达10米,是目前世上最大的光学望远镜。
Explanation : the center of our milky way galaxy is hidden from the prying eyes of optical telescopes by clouds of obscuring dust and gas 说明:在不透光尘埃与云气的遮掩下,我们银河系的中心在可见光望远镜中隐不可见。
Explanation : the center of our milky way galaxy is hidden from the prying eyes of optical telescopes by clouds of obscuring dust and gas 说明:在不透光尘埃与云气的遮掩下,我们银河系的中心在普通可见光望远镜中是难以看见的。
Through the optical telescope , ngc 6240 is shaped like a butterfly . it is so odd - looking because it is in fact the result of the collision of two spiral galaxies 以光学观测, ngc 6240的形状就像一只蝴蝶,它之所以这样古怪,是因为它其实是两个旋涡状星系撞的结果。
Nasa s chandra x - ray observatory has changed this picture ; it provides the sub - arcsecond resolution equivalent to the spatial resolution of ground - based optical telescopes 这个天文台具备低于一角秒的分辨率,精确程度足以和地面光学望远镜媲美,解决了一直以来对应天体证认困难的问题。
However , radio telescopes do have their own shortcoming . firstly , radio astronomical images are not as fascinating as optical images . moreover , they do not work like optical telescopes which can receive all visible wavelengths and then produce monochromatic signals by means of filters 可是,射电天文望远镜也有它的缺点,首先射电天文图像并没有光学照片那么具美感,而且它不像光学望远镜般,可以把可见光全部接收,然后加上滤色片分出单色光。
英文解释
an astronomical telescope designed to collect and record light from cosmic sources
