We can determine the temperature, composition, and line-of-sight velocity of extremely distant astronomical sources just by studying the relative amount of light we receive from them at different wavelengths. In this video, Robert Quimby describes how spectroscopy is used as an important tool in astronomy and the basics of how the data are collected and analyzed. Then a practical example is given of how raw spectroscopic data can be processed (reduced) to determine the redshift of a galaxy.
