彗星的

Sekanina, who has studied how Comet Shoemaker-Levy 9 and others have split apart, has concluded that the events that create these multiple nuclei often occur far from the Sun, even around aphelion.

Sekanina曾经研究过Shoemaker-Levy 9 彗星（1994年撞击木星的彗星——译者注）和其它彗星是如何分裂的。他得出结论，产生这些多重彗核的事件经常发生在远离太阳处，甚至可以是远日点。

The Astrochemistry Laboratory researches on extraterrestrial materials and especially the formation, distribution, and fate of organic compounds (comprised primarily of carbon, like those in living things), space environments including interstellar, cometary, and planetary ices, extraterrestrial organic molecules that made the Earth habitable and may have even been involved in the origins of life.

天体化学实验室主要研究地球外物质，尤其是有机化合物（主要组分是类似生命物质中的碳）的形成，分布以及结果，空间环境，包括星际的，彗星的，和行星的冰层，以及那些使地球可居住和可能参与生命起源的地球外有机分子。

The Centre will continue in the pioneering traditions of astrobiology on panspermia, interstellar and cometary dust, meteorites from Mars, the connection between comets and terrestrial life, and comet-Earth interactions so on.

中心将继续在太空生物学方面的研究，包括胚种学，星际和彗星尘埃，火星陨石，彗星和陆地生物间的联系，彗星与地球间的关系等。

During the time he searched for comets, especially in the early and middle periods, Zhou found 20 comets independently and observed many known comets, despite having little access to comet ephemerides (A'lashankou, Bole is a remote place where transportation and communication are difficult). On 1985 Oct. 17, he independently discovered the comet C/1985 R1, and this achievement was honored by the Purple Mountain Observatory as the first Chinese amateur finding since the founding of the People's Republic of China.

这期间，特别是在他的寻彗早、中期，在没有任何有关彗星信息的情况下（阿拉山口，博乐是个交通，通讯不畅的地方），周兴明先生独立找到20颗彗星和观测了许多已知的彗星。1985年10月17日他独立找到的彗星C/19851(C/1985R1， Comet Hartley-Good)被我国紫金山天文台的专家誉为&新中国成立后的第一个业余发现&。

Representation of panspermia - a theory that the seeds of life are found throughout the universe, and that life arose on Earth when such seeds landed here early in Earth's history.

&有生源说&是胚种论的一种学说，该理论认为地球上的生命是由搭顺风车，乘撞击地球的小行星或彗星的细菌或是生物化学物带来的。

Luckily, Phaethon is a rocky comet that has lost all of its ice because of the hot Sun.

很幸运，法厄同彗星是一颗岩石质彗星，它所携带的冰也因太阳而融化消失。

Now according to Newtonian theory, some of them moved in hyperbolas or parabolas never to return; others moved in ordinary ellipses.

现在，牛顿理论认为，有一些彗星沿双曲线或抛物线运行，永远不再返回；另外一些彗星沿普通的椭圆轨道运行。

The investigations into this remote area were difficult and the findings yielded many interesting theories, ranging from fairly plausible ideas about the arrival of a stony asteroid or comet, to more exotic hypotheses involving black holes, antimatter, mirror matter, volcanoes, ball lightning, and "geometeors," to really bizarre notions about crippled alien spaceships, laser beams from other planets and death rays secretly invented by Nikola Tesla.

这个偏远地区的困难和调查的结果产生了许多有趣的理论，从大约一个石质的小行星或彗星的到来比较可行的想法，更涉及黑洞，反物质，镜子的问题，火山，球状闪电，和异国情调的假设等&geometeors，&约削弱外来飞船真正奇怪的观念，激光束从其他行星和死亡射线秘密尼古拉特斯拉发明。

In 1769 he published An Essay towards a History of Comets. Amidst his various professional avocations, Burney never lost sight of his main project—his History of Music—and decided to travel abroad and collect materials that could not be found in Britain.

另外尚有分成八部份声乐赞美诗则未演出，1769年他出刊了一篇论文讨论「彗星的历史」，在他各种不同的专业嗜好，Burney从不失去他的主要计划，一本「音乐的历史」，也决定出国去收集在英国无法找到的材料。

Comet Lulin's orbit indicates that this is likely the comet's first trip into the inner Solar System.

彗星Lulin的轨道说明了这可能是这颗彗星第一次进入太阳系内部。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.

这是凯特，那个是爱朗。
