On April, 7, 1998, the European Space Agency announced that its infrared space observatory had discovered water on Titan, a moon of the planet Saturn, as well as other places throughout the universe.  Titan is Saturn's largest moon and the discovery of water, according to Roger Bonnet, the agency's director of science, may indicate that conditions there duplicate those same conditions that gave birth to life on Earth.  "Now that water has been discovered...the only thing you need is a little heat, to heat up Titan, and maybe the birth of life may be seen," he said.  Previous to this discovery, scientists have also found evidence for a possible ocean beneath the surface of Europa, a moon of Jupiter.  The European Space Agency's Infrared Space Observatory, also known as the ISO, has been orbiting high above the earth for 2!/2 years, exploring the universe at wavelengths that can't be seen by the human eye.  In a statement to reporters, Richard Genzel, the chairman of the agency's astronomy working group, said that the observatory has permitted scientists to observe water throughout the universe.  "It has been a spectacular vista to see water everywhere," Genzel said.  According to Genzel, the observatory discovered water around newborn stars, dying stars, in interstellar space, in other galaxies and in the atmospheres around Mars and other planets.  The scientist noted that the water was likely brought to the icy outer planets by comets.  Genzel said, "And that is important, because maybe that's the way water came on Earth in the early part of the solar system - when there were many more comets around, and the earth was bombarded by these icy objects bringing in water."  Michael Wysmierski  Information for this article was acquired from the Associated Press.
