As a result, as galaxies grew, so did their central black holes.

结果，随着星系的增长，它们的中心黑洞也在增长。

And usually, it has a doughnut or a half-moon shape with a large, central hole.

通常， 它呈甜甜圈或半月形，中间有一个大孔。

Today you learned that active galaxies pour out lots of energy, due to their central supermassive black holes gobbling down matter.

今天你学到了活跃的星系会释放出大量的能量，因为它们中心的超大质量黑洞会吞噬物质。

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生的，那它很可能同时拥有两个黑洞。

But a single ray of light from the westering sun coming through the central hole in the shelter fell right on the woman.

但是，西斜的太阳从遮蔽物中央的洞口射进来的一缕光线正好落在了女人身上。

Lu said that at the wavelength of 3.5 millimeters, researchers could see how the jet emerges from the ring of emission around the central supermassive black hole.

卢说，在 3.5 毫米的波长下，研究人员可以看到射流是如何从中央超大质量黑洞周围的发射环中出现的。

These donut-shaped proteins, of which there are many types in the cell, all seem to act to rip apart structures by basically pulling individual proteins through a central hole.

这些甜甜圈形状的蛋白种类繁多，分布在细胞各处，看上去全都能将单个蛋白拖进中央孔洞，从而把蛋白结构撕扯开来。

He said the image shows for the first time the connection between the material pulled inward near the central supermassive black hole and the point from which the jet starts.

他说，这张照片首次显示了在中心的超大质量黑洞附近的吸积流与喷流起源之间的联系。
