What is the one reason astronomers make long time exposures?
选项
A、To spend less time at their telescopes.
B、To overcome the problem of weak light.
C、To take more photographs.
D、To photograph astronomical objects without using a telescope.
答案
B
解析
细节题。文章后面讲到由于大部分天体距离很远,所以我们能捕捉到的它们所发出的光线也很微弱,但如果用望远镜充当照相机就可以进行长时间曝光,以此将物体拍下来。故B项正确。
