What is spectroscopy?
How is a spectroscope used in astronomy?
Astronomers can determine the physical properties of an object, like a star, by looking at its light through a spectroscope. The spectroscope can show the gasses that stars emit depending on what type of spectra is shown in the spectroscope. For example, astronomers have concluded that all stars are made up mostly of hydrogen with other elements. Since spectroscopy is used with light, it doesn’t matter if the light is 5 feet away or 5 light years away.
