Its existence had been postulated since the late 19th century, and astronomers working under Percival Lowell, the observatory's founder, had been chasing it photographically since 1906. Now theory had become fact.

从19世纪后期它的存在就被假定了，天文学家们在Percival Lowell的领导下从1906年已经用拍照方法来记录它，现在理论已经变成事实。

At the time astronomers weren't sure whether the body was a planet or a planetlike object, and it remains to be seen if it is truly orbiting the star.

当时，天文学家不能确定这个天体到底是行星还是类行星，是否是真的在轨道上运行的星体还有待观察。

但是这神秘的无线电波已经使全世界的天文学家无比兴奋。

"The ring itself is a fascinating object worthy of study because it is forming stars at a very high rate," said Kartik Sheth, an astronomer at NASA's Spitzer Science Center.

&环中正在高速形成恒星，是一个很值得研究的迷人对象，&美国宇航局斯皮策科研中心的天文学家卡提克·谢斯说。

Around 1150, the Indian mathematician and astronomer Bhaskara described in his Siddhanta Siromani a wheel with containers of mercury around its circumference.

大约1150 ，印度天文学家和数学家的巴斯卡拉中描述他的瓦希丹塔Siromani一个车轮与汞的容器周围围。

Mostly, these are inherited from a system first enunciated in Jyotish Vedanga (one of the six adjuncts to the Vedas, 12th to 14th century BC), standardized in the Surya Siddhanta (3rd century) and subsequently reformed by astronomers such as Aryabhata (499), Varahamihira (6th century), and Bhaskara (12th century).

主要地，它们最初是由《周谛士吠陀》（出于公元前12至14世纪，是吠陀六分支的其中之一）体系继承而来，在《苏雅西德汉塔》里得以标准化，后来陆续被阿里亚巴塔（499），伐罗诃密希罗，毗迦罗等的天文学家革新。

How this wonderful system started and what kept it working with such wonderful accuracy is largely a mystery but astronomers tell us that it is only one of millions of similar systems in spece ,and one of the smallest.

这个奇妙的星系是怎样开始的，什么使它保持精确地运行，这是一个很大的迷。但是天文学家告诉我们太阳系只是太空里几百万个相似的星系中的一个而且是最小的一个。

Astronomers discovered a pair of neutron stars locked in orbit of each other and spewing out beams of radiation.

天文学家发现一对中子星锁定在轨道上，相互借鉴，喷涌出光束的辐射。

Now a professional astronomer. Pollard was recently high on the South African veldt, still stargazing.

现在，作为职业天文学家，波拉德近来在遥远的南非大草原上，仍然在观察星系。

Not that we'll be visiting any time soon, but stargazing astronomers at the Harvard-Smithsonian Center for Astrophysics have discovered a distant Earth-like planet that shares similar qualities with our own world, such as an abundance of water.

美国这不表示我们很快会前往探访，但哈佛─史密森天体物理中心负责观测天体的天文学家已经发现一个遥远的类地球行星，它跟地球具有若干类似特点，例如有大量的水。

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.
