Spectroscopy and Stars!

Collecting the radiation the star gives off, astronomers can determine the brightness of each object. The difference of brightness tells the astronomers the distance of each star, the spectrum also contains the temperature, the mass, the chemical make-up, and the diameter of a star.

By identifying the colors emitted by a star, we can determine which elements make up the gas and what the temperature of the gas.
