WASHINGTON (AP) - Astronomers looking at the spectacular supersonic plumes of gas and dust shooting off one of Saturn's moons say there are strong hints of liquid water, a key building block of life.
Their research, appearing in Thursday's issue of the journal Nature, adds to the growing push to explore further the moon Enceladus, as one of the solar system's most compelling places for potential life.
Using images from NASA's Cassini probe, astronomers had already figured that the mysterious plumes shooting from Enceladus' icy terrain contain water vapor. New calculations suggesting the gas and dustspew at speeds faster-than-sound make the case for liquid, said study lead author Candice Hansen of NASA's Jet Propulsion Lab in California. Her team calculated the plumes travel more than 1,360 mph.
