≤0.3. Second, applying a set of absorption-line indices to the Merit Function for Galactic and M31 globular clusters and the circumnuclear region of M32, we obtain their age and metallicity.

其次，将简单单星族的Lick/IDS系统谱指数应用于品质函数，给出了一些银河系和M31的球状星团，M32中心区域的年龄和金属丰度。

The VLA has been used to discover water on planet Mercury, radio-bright coronae around ordinary stars, micro-quasars in our Galaxy, gravitationally-induced Einstein rings around distant galaxies, and radio counterparts to cosmologically distant gamma-ray bursts.

科学家已藉由VLA发现水星上的水、正常恒星周围会辐射出明亮电波的日冕、银河系中的微类星体、遥远星系周围经重力作用产生的爱因斯坦环、以及遥远伽玛线爆发的电波同位对照影像。

Cosmogenic nuclides are primarily generated by reaction of target nuclei exposed near earth surface and galactic cosmic radiation. The reactions producing Cosmogenic nuclides mainly involve spallation, capture of neutrons and muon reaction.

宇宙成因核素主要是由来源于银河系的宇宙射线与暴露于地表的物质作用形成的，作用机制主要包括裂变、中子捕获和介子反应。

When Aneesa's father was stabbed in the back by an angry customer, Aneesa became the sole crewer for her late father's gigantic jalopy and scoured the galaxy for the scum that left her an orphan.

有一次，一个恼羞成怒的客户从背后捅死了安妮莎的父亲，于是，安妮莎成了她先父的巨型老爷船里唯一的船员。她在全银河系搜捕那个把她变成孤儿的社会渣滓。

If so, understanding the dynamical relationship between the smaller terrestrial planets and the more massive gas and ice giants may help us to understand how common Earthlike planets might be in our galaxy.

& &如果是这样，了解小之间的类地行星和更大规模的天然气和冰巨人动力的关系可以帮助我们理解如何共同Earthlike行星可能会在我们的银河系。

"If so, understanding the dynamical relationship between the smaller terrestrial planets and the more massive gas and ice giants may help us to understand how common Earthlike planets might be in our galaxy."

&如果是这样的话，通过理解小型陆地行星与更大型的气体和冰构成的行星的动力学关系，可以帮助我们理解类地行星普遍存在于银河系之中的可能性有多大。&

We know that the Flood's biology is alien enough that it must be extragalactic in origin.

我们已经知晓虫族的生理结构来自银河系外的某处

"For extragalactic astronomy, the southern hemisphere is the place to be," said Koen.

&南半球是研究银河系外天文的地方，&Koen 说。

Some of its brighter stars have been used as standard candles to establish important estimates of extragalactic distances and the scale of the Universe.

一些它的较明亮的恒星发出的光已经被用作标准光谱分析去建立银河系外星系距离的重要估算和宇宙的度量。

The heretofore unexpected extent of dust beyond the starry limits of the arms, shows new areas for extragalactic astronomical study.

这个在充满恒星的旋臂之外出现的巨大的尘埃云团完全出乎科学家的预料，为银河系外的天文学研究提供的新的课题。

In the United States, chronic alcoholism and hepatitis C are the most common ones.
