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

们的本系团靠近处座系团，两者都是座超系团的一部分。

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

团中的是A系的一部分，离地球大约5千万光年远。

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

距们最近的可能这种方式爆炸的恒是座的 Spica，它离们有100光年远。

He discovered this discrepancy in the Coma  cluster.

他在系团中发现了这一偏差。

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

这是创三患者的工作证。

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

而银河系们本地系群中的其他系围绕座超团的一个质心运行。

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， 当们穿越超系团时，每个微小的点都不是恒， 而是一个系。

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A系是由两个系结合产生的，那它很可能同时拥有两个黑洞。

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.

本系群属于更大的系集合叫做超系团，而它又属于另一个更大的超系团叫做兰天超系团。

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.

直到现在，天文学家都将们所在的银河系其周围的系与座近100个其他系群归类在一个跨度达1亿光年的超级系团中。

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，座超系团实际上只是更大的拉尼亚凯亚超系团的一个附属物，拉尼亚凯亚超系团可能有10万个系，横跨5亿光年。

For example, if you see a chart with, say, Sagittarius rising, you kind of expect that the Midheaven will be in Vervo, because that's the sign 90 degrees before Sagittarius.

例如，如果你看到一张盘显示射手座升起，你可能会预期中天位于座，因为那是射手座前90度的座。

Einstein's theory of general relativity predicted this phenomenon over 100 years ago, but it wasn't directly verified until 2017, when gravitational wave observatories LIGO and VIRGO observed a neutron star collision.

爱因斯坦的广义相对论在一百多年前就预言了这一现象，但直到2017年，激光干涉仪引力波天文台（LIGO）和座探测器（VIRGO）观测到中子碰撞时， 这一现象才得到直接验证。

Between the Great Attractor and us, the Milky Way, there's a relatively empty area, a blue void, and next to us is Virgo, a large and dense cluster whose large galaxies have been observed from Earth for centuries.

在巨引源和们所在的银河系之间， 有一个相对空旷的区域，一个蓝空洞， 而紧邻们的是座， 这是一个庞大且密集的系团， 其中的大系几个世纪来一直被地球上的观测者所观察。

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，正好出现在太阳在座位置的正对面。
