Evidence that life exists on Titan, one of Saturn’s biggest moons, appears to have been uncovered by Nasa scientists.
<...>
Data from Nasa's Cassini probe has analysed the complex chemistry on the surface of Titan, which experts say is the only moon around the planet to have a dense atmosphere.
They have discovered that life forms have been breathing in the planet’s atmosphere and also feeding on its surface’s fuel.
Astronomers claim the moon is generally too cold to support even liquid water on its surface.
The research
has been detailed in two separate studies.
The first paper, in the journal Icarus, shows that hydrogen gas flowing throughout the planet’s atmosphere disappeared at the surface. This suggested that alien forms could in fact breathe.
The second paper, in the Journal of Geophysical Research, concluded that there was lack of the chemical on the surface.
Scientists were then led to believe it had been possibly consumed by life.
Researchers had expected sunlight interacting with chemicals in the atmosphere to produce acetylene gas. But the Cassini probe did not detect any such gas. <
