Url: http://stars.astro.illinois.edu/sow/spectra.html
Creator: Kaler, James B.
Publisher: University of Illinois at Urbana-Champaign
Description: Spectra is a website illustrating how astronomers use spectra to understand what stars are made of, their structures, and their evolution. The page begins with an introduction to the electromagnetic spectrum and then goes into detail about the properties of light. Then it discusses how matter both creates and destroys radiation. It goes on to interpret absorption and emission lines. The website ends with discussing how astronomers use spectra to understand stars, galaxies, and other objects in the universe.
