It was a shooting star that propelled me into astronomy in the first place

　　最初是一顆流星促使我從事天文學(xué)。

　　The discovery is being hailed as The Holy Grail of astronomy.

　　這一發(fā)現(xiàn)圓了天文學(xué)界的一個(gè)夢(mèng)想。

　　Do you know anything about astronomy?

　　你懂天文學(xué)嗎？

　　Mathematics and astronomy are cognate sciences.

　　數(shù)學(xué)和天文學(xué)是互相關(guān)聯(lián)的科學(xué)。

　　This is done in astronomy, with the help of the Julian day.

　　天文學(xué)上就是借助儒略日來(lái)算的。
