So we call this effect “gravitational lensing.”

所以我们称这种效应为“引力透镜效应”。

The researchers said an observation method called gravitational lensing also helped them.

研究人员表示，一种名为引力透镜效应的观测方法也对他们有所帮助。

In gravitational lensing, there are three essential components -- the source, the lens, and the telescope.

在引力透镜中，有三个基本组成部分-光源，透镜和观测点。

Gravitational lensing tends to magnify distant sources and increase their apparent brightness, as rays of light become concentrated.

引力透镜往往会聚焦光束，放大远处的光源并且增加其视亮度。

This  phenomenon is known as gravitational lensing.

这种现象被称为引力透镜。

In both cases, astronomers were able to see the light from the star because of an effect known as gravitational lensing.

在这两种情况下，天文学家都能看到恒星发出的光，因为一种叫做引力透镜的效应。

I ve talked about how the strong gravitational field around a black hole causes a lensing effect.

我已经讨论过黑洞周围的强引力场如何引起透镜效应。

Similarly, light that passes close enough to an event horizon will be deflected in a phenomenon known as gravitational lensing.

类似地，通过足够靠近事件视界的光将在称为引力透镜的现象中发生偏转。

We've tested this phone through its lensing, light levels, the dynamic range, really figuring out how far we could push this phone.

我们通过镜头、光线水平、动态范围测试了这款手机，真正弄清楚我们可以将这款手机推向多远。

Finally, the incredible gravity around a  black hole leads to interesting gravitational lensing effects on the accretion disk  resulting in this familiar image.

最后，黑洞周围令人难以置信的引力导致了吸积盘上有趣的引力透镜效应，从而产生了这张熟悉的图像。
