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

我们的本系团靠近处女座系团，两者都是室女座超系团的部分。

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

距我们最近的可能以这种方式炸的恒是室女座的 Spica，它离我们有100光年远。

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， 当我们穿过室女座超系团时，每小点都不是恒， 而是系。

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，天学家将我们、银河系及其周围的系、室女座和近 100 其他团归为横跨 1 亿光年的超系团。

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.

最近的观测表明，室女座超系团实际上只是更大的拉尼亚凯亚超系团的附属物，拉尼亚凯亚超系团可能有10万系，横跨5亿光年。
