Using a Fancy Spectrograph
Put the spectrograph to good use. Using a spectrograph individuals built themselves, young scientists examine and record the emission spectra of different light sources. They use the spectra to compare and contrast the compositions of...

Using Spectral Data to Explore Saturn and Titan
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...
