2005年，仅仅靠着两台计算机，Jalowiczor夜以继日地分析成千上万的由圣克鲁兹基础大学天文学家们发布的空间测量数据。
Using just two home computers, he spent night after night analysing thousands of space measurements released by astronomers at the Santa Cruz-based university in 2005.

Astronomers studied the supernova using the Chandra X-ray space telescope launched by the American space agency Nasa in 1999.
有趣的是，现代天文学家们认为，空间是有限的，这是让人感到很舒服的一种想法——尤其是对那些从来记不住把东西放在哪的人。
Interestingly, according to modern astronomers, space is finite. This is a very comforting thought — particularly for people who can never remember where they have left things.
天文学专业主要研究星星和星系以及外层空间中恒星的现象。
Astronomy focuses on the planetary. galactic. and stellar phenomena occurring in outer space.
伽玛暴是来自宇宙学空间的一种短时标的伽玛射线突然增强的现象，它的研究已经成为当今天文学和物理学的热点之一。
Gamma-ray bursts (GRBs) are short, sudden and intense flashes of gamma rays from the cosmos distance, the study of which is a hot topic in astronomy and astrophysics.
挨着英国大使馆的是美国海军天文台。天文学家用这个天文台研究地球，太阳，月亮和其他空间物体的位置和运动。
