Inside most galaxies a supermassive black hole lurks.

在数的银河系中都会隐藏黑洞。

But what about supermassive black holes?

但如果是超量黑洞呢？

And I study supermassive, hyperactive, black holes called " blazars" .

我研究的是量、极度活跃的黑洞，叫做“耀变体”。

It's believed the center is a supermassive black hole.

人们相信银河系中心有巨的黑洞。

Most galaxies are built around supermassive black holes.

数星系都是围绕超量黑洞建造的。

At the center of the galaxy is a supermassive black hole.

该星系的中心是量的黑洞。

Supermassive black holes are far bigger, millions or billions of kilometers across.

超量黑洞要得，直径达数百万或数十亿公里。

So make sure to choose a supermassive one.

所以定要选择量的恒星黑洞。

Seeing the whole area near a supermassive black hole can be helpful to scientists.

观测超量黑洞附近的整区域对科学家会有帮助。

Even supermassive black holes in galactic centers evaporate.

即使是星系中心的超量黑洞也会蒸发。

There are also supermassive black holes.

还有超量的黑洞。

We now think that these supermassive black holes form at the same time galaxies do.

我们现在认为这些超量黑洞是与星系同时形成的。

And finally there are the supermassive black holes that are at the center of most galaxies.

最后是位于数星系中心的超量黑洞。
