Just days after space shuttle astronauts repaired the Hubble space Telescope in mid December, the giant lens focused on a star cluster at the edge of the universe - and photographed heaven.

仅在航天飞机的宇航员于12月中旬修复哈勃太空望远镜几天之后，特大镜头聚焦于宇宙边缘的一个星团——拍摄到了天国。

In the experiment we used convex-plane unstable resonator, and analysis the convex mirrors and gain medium thermal lens as a telescope system.

实验采用凸平直线非稳腔，将凸面镜和增益介质热透镜效应等效为望远镜系统进行分析。

Perhaps its greatest moment came in 1979 when it was the first telescope to observe a gravitational lens, an effect where a "massive" object bends electromagnetic radiation such as light around it.
