Aliens exist on Saturnís moon?
LONDON: Scientists at US space agency Nasa have found vital clues to suggest that primitive aliens could be living on Titan, one of Saturnís biggest moons.
On the basis of chemical composition found on Titanís surface, the experts believe that life forms have been breathing in the planetís atmosphere and also feeding on its surfaceís fuel. The research based on the analysis of data sent from Cassini probe has been detailed in two separate studies.
The first paper, in the journal Icarus, shows that hydrogen gas flowing throughout the planetís atmosphere disappeared at the surface. This suggested that alien forms could breathe.
The second paper, in the Journal of Geophysical Research, concluded that there was lack of chemical on the surface as it had been possibly consumed by the living aliens, the Telegraph reported.
ďWe suggested hydrogen consumption because itís the obvious gas for life to consume on Titan, similar to the way we consume oxygen on Earth,Ē said Chris McKay, an astrobiologist working at Nasa. ďIf these signs do turn out to be a sign of life, it would be doubly exciting because it would represent a second form of life independent from water-based life on Earth.Ē
Professor John Zarnecki, of the Open University, said: ďWe believe the chemistry is there for life to form. It just needs heat and warmth to kick-start the process. ďIn four billion yearsí time, when the Sun swells into a red giant, it could be paradise on Titan.Ē
