18.Together, all the colors make up the spectrum of visible light—the light we can see.

所有的颜色一起构成了可的谱——我们所能看到的。

19.Furthermore, it lies behind a shroud of dust that blocks any visible light from passing through.

此外在它前面还有一层阻隔任何可线通过的尘埃。

20.Radio waves pass right around “normal” telescopes, ones that we use to observe visible light.
