How are elements identified in stars?

Elements are identified in stars using the technique of spectroscopy. This technique can be preformed using a spectroscope which analyizes the radiation of light coming from a star. The radiation will give off a light pattern that helps astronomers identify the elements in stars.

What are the different types of spectrums?

  • Continuous Spectrum- Unbroken bands of color

  • Emission Spectrum- Unevenly spaced lines of color on a dark background

  • Absorption Spectrum- Unevenly spaced dark lines on a colored background

How is identifying elements in stars helpful to astronomers?

This is helpful because astronomers can obtain a great amount of information about the sun and stars energy motions and temperatures.
