1·But astronomers laboured hard to analyse the results of these expeditions to observe Venus transits.

但是天文学家辛苦分析这些观测金星凌日的探险活动的结果。

2·Transits have helped shape our view of the whole Universe, as Heather Cooper and Nigel Henbest explain.

正如希瑟·库珀和奈杰尔·亨贝斯特解释的那样，凌日帮助我们形成了对整个宇宙的看法。

3·For centuries, transits of Venus have drawn explorers and astronomers alike to the four corners of the globe.

几个世纪以来，金星凌日吸引了探险家和天文学家们汇聚到地球的四个角落。

4·But there was a problem: transits of Venus, unlike those of Mercury, are rare, occurring in pairs roughly eight years apart every hundred or so years.

但有一个问题：和水星凌日不同的是，金星凌日是罕见的，大约每隔一百年会成对出现八年的时间。

5·But such transits have paved the way for what might prove to be one of the most vital breakthroughs in the cosmos—detecting Earth-sized planets orbiting other stars.

但是这样的凌日现象已经为被证明可能是宇宙中最重要的突破之一的说法铺平了道路，这个说法即找到那些围绕其他恒星轨道公转的和地球大小相似的行星。

6·Reasonably accurate for the time, that is quite close to today's value of 149,597,870 km, determined by radar, which has now superseded transits and all other methods in accuracy.

那个数值与今天雷达测定的149,597,870公里相当接近，就当时来说准确度很合理，雷达在精度上已经取代了凌日和其他所有方法。

7·But there was a problem. Transits of Venus are rare.

但有个问题，金星凌日很难得。

8·That's because these transits of Venus don't happen often.

这是因为这次的金星凌日不会经常发生。

9·No problem, I've a flight that transits in Bangkok, is that ok?

没问题，我这里有一班在曼谷转机的，可以吗？

10·Transits over a natal planet bring it into focus, make it more personal.

经行出生行星时会使其成为焦点，更个人化。
