Its thousands of stars had been part of the M87 galaxy, about 50 million light-years away.

团中是室女A一部分，离地球大约5千万光年远。

Our Local Group is near the Virgo Cluster, and both are part of the Virgo Supercluster.

我们本团靠处女团，两者都是室女超团一部分。

This I.D. was with the woman in Trauma 3.

这是创伤三室女患者工作证。

The nearest star that might explode in this way is Spica, in Virgo, and it's well over 100 light years away.

距我们最可能以这种方式爆炸恒是室女 Spica，它离我们有100光年远。

And the Milky Way and the rest of our local group of galaxies orbit a barycenter in the Virgo Supercluster.

银河和我们本群围绕室女超团一个质心运行。

If M87 is the product of a merger of two galaxies, it might host two central black holes in a binary system, researchers say.

如果室女A是由两个结合产生，那它很可能同时拥有两个黑洞。

Switching back to visible light, as we traverse the Virgo Supercluster, each tiny dot not a star, but a galaxy.

切换回可见光， 当我们穿过室女超团时，每个小点都不是恒， 而是一个。

Our Local Group belongs to an even bigger collection of galaxies called the Virgo supercluster, and this supercluster belongs to an even larger supercluster, known as Laniakea.

本群属于更大集合叫做室女超团，而它又属于另一个更大超团叫做兰天超团。

Until now, astronomers grouped us, the Milky Way and its surrounding galaxies, with Virgo and nearly 100 other clusters in a supercluster that stretches 100,000,000 lightyears across.

到目前为止，天文学家将我们、银河及周围、室女和 100 个团归为一个横跨 1 亿光年超团。

Recent observations indicate the Virgo Supercluster is actually only an appendage of the even larger Laniakea Supercluster, which may have 100,000 galaxies in it stretching across 500 million light years.

最观测表明，室女超团实际上只是更大拉尼亚凯亚超团一个附属物，拉尼亚凯亚超团可能有10万个，横跨5亿光年。

This dust is illuminated by  the sun and forms a band of light known as the Zodiacal light, which spans from horizon  to horizon featuring a central focus called the gegenschein, appearing directly  opposite the sun's position over Virgo.

这些尘埃被太阳照亮， 形成了一条被称为黄道光光带，这条光带从地平线一端延伸到另一端， 中心焦点称为对日照，正好出现在太阳在室女位置正对面。
