Build Your Own Space Scrapbook
This new astronomy Web resource provides easy access to the rich repository of black-and-white images and spectra of stars and galaxies stored in the MAST digital archives. While a picture shows astronomers what a celestial object looks like, a spectrum provides information about its physical nature and its motion toward or away from Earth. Astronomers analyze spectra and images of a celestial body to get a complete picture.
