WATER VAPOR DISCOVERED
ON TITAN, OTHER STARS

In an April 9 report, European astronomers using the Infared Space Observitory have found water in the atmosphere of Saturnís largest moon Titan, and in the vicinity of other nearby stars. The discovery is significant because temperatures in space would normally freeze water vapor. In the case of Saturnís moon Titan, the existance of water vapor in the moonís upper atmosphere could mean that life could develop on Titan if the moon were heated to Earth-like temperatures. NASAís Cassini mission, now on its way to the Saturn system, will likely investigate the discovery in detail.
