天文学家已经发明出一种叫做自适应光学的技术，可以以自己的模糊方式突破大气层。

Astronomers have devised a technique called adaptive optics that can beat Earth atmosphere at its own game of blurring.

尽管我从未造出一个我自己的望远镜，但是很多真正的天文学家却做到了，同时很多这个专业的成员为我们理解光学作出了重要的贡献。

I never built my own telescope, but a lot of real astronomers did, and many of the earliest members of the profession made considerable contributions to our understanding of optics.

天文学家借助哈勃太空望远镜的光学过滤器，可以准确查明该星云的化学组成、温度和密度，并追踪恒星的死亡过程。

Optical filters in the space telescope allowed astronomers to precisely determine the nebula's chemical makeup, temperature, and density, and to trace the stages of the star's demise.
