Saturn is really far away, but knowledge of its composition is within reach. Future astronomers learn how scientists use spectra to remotely determine the chemical composition of a planet or moon. They try out this concept by analyzing the spectra of Saturn's ring and Saturn's moon, Titan, to identify the elements that are present.
