"Extragalactic nebula" is a former name for "galaxy".

&外星云&是&星系&的曾用名。

The detection of extragalactic PNe also allows them to be used as standard candles for extragalactic distance scales, probes of distribution of dark matter, as well as tools to study the dynamic history of galaxy clusters.

另外，银河系外的行星状星云既可以用作测量系外距离的标准烛光，又可以成为侦测暗物质分布的探针，及研究星系团动力学历史的工具。

In this image, taken by the Hubble Space Telescope, new stars can been seen inside fingerlike protrusions extending from the top of the nebula.

在这张图像上，运用的哈勃太空望远镜，新的恒星被认为是里面指状的突出延伸，从最高层的星云中。

The major bacterial phyla were α-proteobacteria,β-proteobacteria,γ-proteobacteria, Synechococcus, Actinobacteria, Bacteriodetes, Planctomycetes, etc. The specific species of free-living bacteria are unclassified of γ-proteobacteria and α-proteobacteria, Flavobacterium, Vibrio, Aeromonas, Legionellaceae.

通过与GenBank中已有序列的比对，发现太湖、巢湖、滇池、星云湖中细菌的主要类群为：变形菌的α-、β-和γ-亚纲（alpha-， beta-， and gamma- subdivision）、聚球蓝细菌，放线菌、拟杆菌、浮霉菌。

Bright spots in the Horsehead Nebula 's base are young stars just in the process of forming .

马头星云中的那些明亮的点都是一些正在形成的明亮恒星。

Explanation: The famous Horsehead Nebula in Orion is not alone.

解说：猎户座中著名的马头星云并不孤单。

The Horsehead Nebula lies 1,500 light years distant towards the constellation of Orion.

马头星云位在北天的猎户座里，距离我们约有一千五百光年。

Fittingly named the Horsehead Nebula, it is some 1,500 light-years distant, embedded in the vast Orion cloud complex.

这朵星云是庞大的猎户座云气团的一部份，距离我们约有1500光年。

Fittingly named the Horsehead Nebula, it is some 1,500 light-years distant, embedded in the vast Orion cloud complex.

这朵星云是庞大的猎户座云气团的一部份，距离我们约1500光年。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
