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

星团中星星是室女A星系一部分，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.

本星系团靠近处女座星系团，两者都是室女座超星系团一部分。

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.

距最近可能以这种方式爆星是室女座 Spica，它离有100光年远。

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星系是由两个星系结合产，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， 当穿过室女座超星系团时，每个小点都不是星， 而是一个星系。

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.

本星系群属于更大星系集合叫做室女超星系团，而它又属于另一个更大超星系团叫做兰天超星系团。

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、银河系及其周围星系、室女座和近 100 个其他星团归为一个横跨 1 亿光年超星系团。

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.

最近观测表明，室女座超星系团实际上只是更大拉尼亚凯亚超星系团一个附属物，拉尼亚凯亚超星系团可能有10万个星系，横跨5亿光年。
