How Elements Are Identified in Stars

Ever wonder what's actually going on in our universe? Almost everyone knows that stars are really just huge balls of gas, but is that really it? With spectroscopes and the science of spectroscopy, we are able to identify different elements in stars by examining the spectra (colors) produced from the electromagnetic radiation the star is emitting. Each element has its own unique light spectrum that makes it possible for scientists to identify it with a spectroscope. This is important for Astronomers because you can understand a lot about an object or element just by the kinds of light it contains, So if an object is extremely far or unobtainable such a star you can still obtain a lot of information about it and the light it emits just by using a spectrometer. For example, Jupiter's absorption spectrum allows astronomers to identify hydrogen, helium, and other elements in its atmosphere.
