Galileo Finds Veritable Chemical Factory On Europa
News story originally written on March 29, 1999

Scientists have found another chemical on Jupiter's moon Europa. The chemical is hydrogen peroxide. You might have used hydrogen peroxide in toothpaste to whiten your teeth. Or you might have used it to clean germs out of a cut.

There are other chemicals on Europa. The Galileo spacecraft has found water, carbon dioxide, and maybe even salt.
