Identifying Elements Found in Stars

How elements are identified in stars

Every element has an unique spectrum that can be seen when looked at through a spectroscope. The study of this is called spectroscopy. The elements unique spectrum is used to identify which elements this star contains, almost like a finger print. Neon has one of the brightest "finger prints" of all the elements.

How is this helpful?


We cannot visit far away stars, so to know what elements that they are made of we need to use a spectroscope. By using a spectroscope we can see what tags make up a certain star. When a scientist wants to know what makes up a star in a far away galaxy they can use a spectroscope to view the star's spectrums. These spectrums are unique to an element which allows us to see what elements make up a star.
