Visible light just passes over them.

可只会穿过它们。

Infrared has a longer wavelength than visible light.

红线波长比可更长。

That energy is emitted as photons of visible light.

能量以可子形式发射。

And these colors aren't limited to visible light.

而且这些颜色并不局限于可。

Thick dust is also very good at absorbing visible light.

厚厚尘埃也很善于吸收可。

The wavelengths we see through our eyes, we call visible light.

我们通过眼睛看到波长，我们称之为可。

Its neutrinos reached Earth about three hours ahead of the visible light.

这些微子比可提前三小时抵达地球。

The exoplanet Fomalhaut b was the first one photographed with visible light.

这个名为“北落师门b”行星是第一个用可视拍到行星。

Just like visible light, x-rays are less likely to penetrate denser materials.

类似于可，X线难以穿过密度高物体。

There, they absorb infrared radiation and convert it to visible green light.

在那里，它们吸收红辐射，并将其转化为可绿。

This is what we call “visible light, ” also known as the visible spectrum.

这就是我们所说“可”，又叫可谱。

At the lower end of the spectrum, there's radio, infrared, and visible light.

在谱低频端是无线电，红线，和可。

Together with visible light, all these types of radiation are called the electromagnetic spectrum.

同可一起，所有类型辐射都叫做电磁频谱。

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

所有颜色一起构成了可谱——我们所能看到。

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

此在它前面还有一层阻隔任何可线通过尘埃。

But in visible light the planet looks almost featureless.

但在可下裸眼观看，这颗行星看起来就几乎毫无特色。

A typical optical telescope has a diameter a few million times the wavelength of visible light.

传统学望远镜直径是可波长数百万倍。

The whole kaboodle lets visible light pass untrammelled, while absorbing infrared and converting it into heat.

整个结构能够让可自由通过，同时吸收红线并将其转化为热。

It's actually infrared light, and the only difference between infrared and visible light is the wavelength.

实际上这是一种红线，对于可和红线来说唯一区别就是波长。

On the left-hand side shows you what we see with visible light with the Hubble Space Telescope.

左边图像是我们用哈勃望远镜看到可。
