天体的

In addition, there are thousands of small bodies such as asteroids and comets.

此外，被发现的还有成千上万的小型天体像是小行星和彗星。

We observed many winter showcase DSOs and some less well traveled DSOs, and then finished with Jupiter near zenith.

我观测了一些冬季的深空天体以及天顶的木星。

Conversely, astrometry works best when a planetary system is "face-on" when seen from Earth, because then the star's movements in the orbital plane are most pronounced.

与之相反，从地球看去行星系统是&面向&的时候天体测量最有效，因为此时恒星在轨道面上的运动最显著。

We are in irreversible decline, says Sandra Faber, a professor of astrophysics at UC Santa Cruz who has inadvertently become a mouthpiece for a fed-up faculty.

我们正处于不可逆转的下降中，加州大学圣克鲁兹分校的天体物理学教授桑德拉法伯说。

We are in irreversible decline, says Sandra Faber, a professor of astrophysics at UC Santa Cruz who has inadvertently become a mouthpiece for a fed-up faculty.

我们正面临着无可逆转的下滑趋势，加州大学圣克鲁兹分校的天体物理学教授桑德拉。

We are in irreversible decline," says Sandra Faber, a professor of astrophysics at UC Santa Cruz who has inadvertently become a mouthpiece for a fed-up faculty. University excellence, she says,"took decades to build. It takes a year to destroy it.

我们的衰落无可挽回，&天体物理学教授桑德拉·法贝尔说，法贝尔教授任教于加州大学圣克鲁兹分校，偶然成为了愤怒教工的喉舌，她说，大学成就&耗费几十年心血铸就，不料毁于一年。

A bright sparkling glow in the sky last Wednesday night puzzled some sky gazers in Wisconsin, the US. As it turned out, the mysterious celestial event was urine and waste dumped by astronauts aboard the space shuttle Discovery as they were ending their mission to the International Space Station, America Online reported.

据《美国在线》报道，9日晚，美国数名天文爱好者在威斯康辛州观测到夜空中出现一条明亮的发光带，以为是神秘天体，后被证实是&发现号&航天飞机宇航员在结束国际空间站维修任务后，倾倒在太空中的尿液和废物液体。

Remarkably, the LBAS includes 10 high-energy-peaked BL Lacs, sources which were previously difficult to detect in the GeV range.

特别值得一提的是LBAS包括了10个高频BL Lac天体，这些源以前通常认为是很难在GeV波段观测到的。

"Studying Epsilon Eridani is like having a time machine to look at our solar system when it was young," said researcher Massimo Marengo, an astronomer at the Harvard-Smithsonian Center for Astrophysics in Massachusetts.

&研究恒星' E 波江'就象有了一台时间机器，可以用来观察我们太阳系年轻时的情形，&研究人员马西莫·马伦果说。马伦果是马萨诸塞州哈佛-史密森天体物理中心的一位天文学家。

Asteroids are bigger versions of the meteoroids that race across the night sky.

小行星是比那些穿过夜空的流星更大的天体。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
