Orbiting high above earth, Europe's Infrared Space Observatory has discovered water around stars and planets and in many other unexpected places, raising expectations of life elsewhere in the universe, according to the European Space Agency.The diecovery of water vapour in the atmosphere of Saturn's largest moon, Titan, has generated the most excitement, because that moon may duplicate the conditions that led to the creation of life on earth, said Mr Roger Bonnet, the agency's director of science.
