天体的

In addition to the sun, other stars may also have their own planets, broadly speaking, any movement around the star, the quality does not meet the thermonuclear reaction can produce the quality of the main sequence stars the approximate lower limit of spherical objects can be called planets .

除太阳外，其他恒星也可能有自己的行星，广义上说，凡是环绕恒星运动的，质量未达到能产生热核反应的主序星质量下限的近似球形的天体都可称为行星。

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。

Orion KL hot molecular core is known to be rich in organic molecules; the brightness ( 105L ) and proximity ( 450 pc) of Orion KL make it a primary target for molecular line search and astrochemistry study.

猎户座KL热分子云核是个已知富含有机分子的天体，它的亮度(~ 105 Lsun)以及相对於太阳如此近的距离(~ 450 pc)非常适合我们来寻找在太空中尚未被指认出来的重要分子以及做天文化学上的研究。

Once an object is located, full-color presentations will blow you away with stunning astrophotography, entertaining audio descriptions, color videos, astronomical mythology, folklore, scientific fun facts and much more!

一旦找到目标，真彩色的屏幕就能给您提供震撼的天体摄影技术带来的彩色资料，有趣的音频解说、彩色影片资料、天文神话、传说、有趣的科学知识等等！

But how do relatively rare titans such as Betelgeuse emerge from the same stuff that usually yields batches of sun-sized orbs and even more common red dwarfs?

但是象参宿四那样相对稀少的巨型恒星是如何出现的呢？同样多的物质材料通常可以产生一批象太阳大小的天体，甚至可以产生更多的普通红矮星。

Earth's collision with another large celestial body after much of the Earth's iron fell to its core.

其他的理论家提出，在地球的大部分铁沉入到地核之后，由于地球与另一个庞大的天体发生碰撞，月亮便从地球那石质的地幔中撕裂开来而形成的。

Singular perturbation theory and method for solving nonlinear problems is an important tool on the origin of celestial mechanics and nonlinear vibration problems,and its advantage is enough to give the right solution for structural analysis.

奇异摄动理论和方法是求解非线性问题的重要工具，它起源于对天体力学和非线性振动问题的研究，它的优点是能够给出足够正确的解的解析结构。

Ed Mitchell, on his way back from the Moon, realized that "the molecules of my body and of the spacecraft and of my partners were manufactured in some ancient generation of stars and that was an overwhelming sense of oneness and connectedness."

在从月球返回的途中，埃德·米歇尔意识到："组成我的身体、宇宙飞船以及我同伴身体的分子形成于一些年代久远的天体——这给人一种强烈感受，那就是我们是一体的和相关的。"

Accordingly, as the major targets weighing the quality of the telescope,its luminous energy concentration degree directly influence the quality of the image of the celestial body. So many kinds of technique about the optical quality testing of telescope have came forth. Hartmann screen test is one of the most classical among them and it has become one of the main testing method on several large-scale telescopes in the world because of some strongpoints suchas briefness, visuality and easy handlment.The image through the350mm telescope of the Yunnan observatory has aberration in general, subsequently,the relative position of the primary mirrior has err when blooming and reinstalling .

因此，天文望远镜光能集中度作为衡量天文望远镜质量的重要指标，直接影响到所成天体像的质量好坏，所以就出现了多种天文望远镜光学质量检测方法，其中最经典的是哈特曼光栏法，它因简单、直观、操作方便等优点而成为世界上多台大型天文望远镜的重要质量检测方法之一。

Thus it is important to investigate the unstable properties, much of which can be obtained by employing the MHD model.

这些不稳定性的诸多性质都可用磁流体力学模型进行研究，研究的结果为等离子体实验和天体物理观测中的许多现象提供了直观的认识。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.
