It's certainly possible, and one way to find out would be to look for stars that have a very similar elemental composition as the Sun.

这当然是可能的，找到答案的其中一种方法，就是寻找与太阳有非常相似元素组成的恒星。

While we’re observing these stars, we can use a spectrometer, the device that separates wavelengths, to reveal the star’s absorption spectrum and its elemental composition.

在观察这些恒星时，我们可以使用分光计（一种分离波长的设备）来揭示恒星的吸收光谱及其元素组成。

The gas will emit a line spectrum, a distinct pattern of lines at certain wavelengths that correspond to the elemental composition of the cloud – in this case, hydrogen.

这种气体会发出线谱，一种在特定波长上的独特线条图案，对应于云的元素组成——在这种情况下是氢。
