The findings, published in the 11 May 2007 issue of 'Science', were gathered using the Cassini spacecraft, cooperative mission of NASA, the European Space Agency and the Italian Space Agency.
The atmosphere of Titan is of great interest as it is the only one in the solar system remotely like that of Earth, containing a nitrogen-rich mix of gases.
