When he examined their spectra, he saw that almost all of them were highly redshifted.

当他检查它们的光谱时，他发现几乎所有的原子都有高度的红移。

We now know it to be true for every distant galaxy we observe: they are all redshifted, all heading away from us.

我们现在知道，对于我们观察到的每一个遥远的星系来说，这都是真的：它们都是红移的，都在远离我们。

Once astronomers recognized and could measure redshift, they found that the spectra from nearly every distant galaxy was redshifted, meaning that every galaxy was moving away from us.

一旦天文学家认识到并能够测量红移， 他们发现几乎每个遥远星系的光谱都发生了红移，这意味着每个星系都在远离我们。

So you need a big telescope operating in the infrared like JWST in order to see those very first galaxies, the ones which are moving so fast away from us, that all of their light is redshifted into the infrared.

所以你需要像 JWST 这样的大型红外望远镜才能看到那些最早的星系，这些星系正在快速远离我们，以至于它们所有的光都被红移到红外线。

The light the Universe emitted at the time would've been like a star, in the visible part of the electromagnetic spectrum, but the light that reaches us billions of years later — now — should be redshifted into microwave wavelengths.

在电磁波谱的可见部分，宇宙当时发出的光就像一颗恒星，但数十亿年后到达我们这里的光——现在——应该被红移为微波波长。
