恒星

That is, movement adds only a fraction of the medium's velocity to the light (predicted by Fresnel in order to make Snell's law work in all frames of reference, consistent with stellar aberration).

即运动增添仅为介质的速度轻(预言菲涅尔为了使斯涅耳定律在各项工作的参照系，符合恒星像差)。

Growing from the forming of flame combustion process and plant of the snow flake, one can all realize the existence of chemical meaning. Moreover, one can find the world to be profound to reach, observe fixed star and evolve theory examine, and even as small as plastic bag, wash bowl precise, catalyst converter, nanotech material in detail.

从雪花的形成、火焰燃烧过程以及植物生长等，都可体会到化学意涵的存在，甚至大到发现世界奥妙，观测恒星和演化论推究，小到塑胶袋、洗碗精、触媒转换器、奈米材料中都可一窥其境。

The sun is one of the biggest stars in the solar system.

太阳是太阳系中最大的恒星之一。

Astronomers think that about 2 solar masses of gas per year are transformed into stars in this galaxy.

天文学家认为，这个星系中的气体以每年2个太阳质量的速率形成恒星。

That same rim of dust appears bright in Spitzer's infrared image, which also reveals that Sombrero's central bulge of stars.

这条尘埃带在斯必泽的红外图象中呈明亮的条带。红外图象中亦可见草帽星系由恒星组成的核球。

In the universe,are we alone,or is there life out there in space?

宇宙中有这么多的恒星，我们是孤独的吗？

Most of the stars speckled across this image belong to the nearby spiral galaxy NGC 253, which is out of view to the right.

本图中的大部分恒星点都是邻近的涡旋星系NGC 253的，它在图外的右方。

A convenient classification of stars is based upon the observed sequence of spectral types.

一种实用的恒星分类法是基于测得的光谱类型序列。

Molecules around stars leave imprints in their light, which the spectrograph can detect.

恒星中的分子会在光谱中留下特殊标识，通过摄谱仪就能识别。

For every large time intervals and for stars near to the pole, it is necessary, however, to use the exact formulae of spherical trigonometry.

对于很长的时间间隔和靠近极星的恒星，必须使用精确的球面三角公式。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
