We can figure out the chemical makeup of another star by comparing the spectrumpattern it has to the pattern of elements in the laboratory.
我们可以通过比较恒星的光谱和实验室元素的光谱来确定某颗恒星是由某种元素构成的。

So we can figure out the chemical make up of the other stars by comparing this spectrumpattern it has to the pattern of the element in the libraries.
所以我们可以我们可以通过以库中的光谱样式和它们有的光谱样式来进行对比从而估算出别的行星的化学成分。

This light is passed through a prism, which breaks it up into a spectrum, and a unique pattern, kind of like a chemical fingerprint of spectral lines for that element appears.
