Sounds ethereal, right?
听起来是虚无缥缈的，对吧？
This is the sound of hydrogen, the most common element in the universe.
这是宇宙中最常见的元素，氢的声音。
It's the simplest atom, the building block of stars,
它是最简单的原子，是恒星的组成部分，
and the stuff that turns unsaturated fat into saturated fat.
不饱和脂肪酸利用氢化过程转换为饱和脂肪酸。
It also blew up the Hindenburg.
兴登堡号飞船也因氢气发生爆炸空难。
But how are we listening to hydrogen?
但我们怎么才能听到氢的声音呢？
It doesn't normally make noise, does it?
它通常不会发出噪音，对吧？
Well, atomic hydrogen absorbs and emits radiation at certain frequencies: its atomic spectrum.
氢原子吸收并放射出特定频率的辐射，也就构成了它的原子光谱。
And, if hydrogen emitted sound waves instead of light waves, this is what it would sound like
而且，如果氢发射的是声波而不是光波，那么听起来就是这个样子
(though I did pitch-shift it down so it would be audible to the human ear)
（尽管我确实把它调低了音，这样人耳才能听得见）。
So, just like you might have seen false-color pictures of galaxies
所以就像你看到的星系和行星的假色图像一样，
and planets made by shifting infrared or radio-wave images into the visible spectrum,
通过将红外或无线电波图像转换成可见光谱，
this is a false-pitch sound, shifted into the audible spectrum.
这就是氢被转换到声谱中的假调声音。
And it's what our eyes hear when they see this: Enjoy
就是我们在看到这个图片时所听到的声音。好好享受氢的声音吧。
