Summary:To learn anything about a star, astronomers must analyze its light. They accomplish this by pointing a telescope at the star to gather its light and then using a spectroscope to spread the light into a spectrum. By comparing and analyzing patterns in the spectra of many stars, astronomers have learned to infer stars' compositions and temperatures. The brightness of different colors and the location and width of dark absorption lines in a star's spectrum all provide information about the star. Examine the differences in the example spectra.
