NASA said Tuesday images from the Cassini spacecraft have revealed additional evidence of methane or ethane seas on Saturn's Titan moon. "We've long hypothesized about oceans on Titan," the University of Arizona's Jonathan Lunine, a Cassini scientist, said "and now with multiple instruments we have a first indication of seas that dwarf the lakes seen previously."
The Cassini spacecraft has revealed complex organic material in the atmosphere of Saturn's Titan moon. Scientists think Titan's atmosphere could resemble that of primordial Earth. The finding could help them understand how life on Earth began.
Images beamed back to Earth by NASA's Cassini spacecraft show about a dozen lakes spread across the landscape of Saturn's Titan moon. One scientist called Titan, which also shows signs of volcanic eruptions, a "dynamic and active place."
The spacecraft Cassini, a joint effort of NASA, the European Space Agency and the Italian Space Agency, will slip into orbit around Saturn this week. In December, the Huygens probe, developed by the European Space Agency, will be dispatched from Cassini to land on Titan, Saturn's frozen moon.
