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

我们的本靠近处女座，两者都室女座超的一部分。

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爆炸的室女座的 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.

银和我们本群的其他围绕室女座超的一个质心运行。

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时，每个小点都不， 而一个。

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，室女座超实际上只更大的拉尼亚凯亚超的一个附属物，拉尼亚凯亚超可能有10万个，横跨5亿光年。

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、银及其周围的、室女座和近 100 个其他归为一个横跨 1 亿光年的超。

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的光带，这条光带从地平线的一端延伸到另一端， 其中心焦点称为对日照，正好出现在太阳在室女座位置的正对面。
