天体的

Astronomy the alignment of the Earth and a planet on the same side of the sun.

较小天体或伴星比它所绕转的主星更近观测者的一次合。

Annular Eclipse 环食 An eclipse in which the shadow cone of the obscuring object is not large enough to fully cover the object being obscured.

当掩盖物的影锥比较细小而不足以把被掩盖的天体完全遮盖时，环食便会发生。

A novel method for redshift determination and spectral line identification of celestial spectra is presented, which is based on the knowledge of feature spectral lines.

摘要该文给出了一种基于知识的天体光谱的红移测量和谱线证认方法。

The degree of "redshift" or "blueshift" is directly related to the object's speed in the direction we are looking.

红移或蓝移的程度直接取决于天体在我们视向的移动速度。

Kuiper belt objects are the outermost members of the solar system.

柯伊伯带的天体是太阳系最外围的成员。

The goal of TAOS project is measuring the number and size distribution of Kuiper Belt Objects down to a few kilometer size of cometary nuclei.

中文摘要中美掩星观测计画的目标为测量彗星核大小至几公里的古柏带天体之数量与大小分布。

Currently about 97 times further from the sun than the Earth, the planet is the farthest-known object in the solar system, and the third brightest of the Kuiper belt objects.

目前它到太阳的距离约为98个天文单位，是太阳系内已知最遥远的天体，其亮度在科伊伯带中居于第三位。

Researchers are already on the lookout for such "occultations" of stars by Kuiper Belt Objects that are too small and dim to detect by other methods.

研究人员已经开始留意这些被凯伯带的天体遮掩的恒星，由于它们太昏暗，而且体积非常小，因此用其他方法很难发现。

To see infrared light from the cosmos, WISE must be chilled to out-of-this-world cold temperatures.

中新网11月19日电美国宇航局计划，在下月把一台太空望远镜送上环球轨道，以扫描此前未知的遥远天体发出的红外线。

Astrophysicists think dying stars about three to 20 times the mass of the sun can form these strange objects.

天体物理学家认为比太阳大3到20倍的垂直恒星才会形成这些奇怪的物体。

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.
