Aliens that ‘drink petrol’ could be on Saturn’s moon Titan, scientists claim
Alien’s that “drink petrol” could be living on one of Saturn’s moons, scientists have claimed.
Organisms that feed on chemicals – mainly methane and ethane – could be living on Titan in beyond freezing minus-179C temperatures.
It comes after Nasa and China set off on missions to establish whether there has, or is, life on Mars.
Scientists have debated what the definition of alien “life” should be as they examine which eco-systems would be capable of sustaining a living thing.
Astro biologist Lynn Rothschild from Nasa’s Ames research centre told The News Alerts: “You can’t hunt for something if you have no idea what it is.”
Only a handful of boffins think that extraterrestrial life – if it exists at all – would rely on the same chemicals as we have on earth.
“Nasa needs a definition of life so it knows how to build detectors and what kinds of instruments to use on its missions,” says zoologist Arik Kershenbaum of the University of Cambridge told The News Alerts.
“It would be wrong to assume that our familiar biochemistry is what we’re going to find on other planets.”

One school of thought that has emerged is that aliens may be feasting on petrol on a moon near Saturn.
Titan’s surface is too cold for water but a mission in 2005 revealed that there are lakes of another kind, made of hydrocarbons similar to petrol.
And one scientist has suggested that there could a extraterrestrial life feeding in the petrol lakes.
Planetary scientist Stuart Bartlett of the California Institute of Technology in Pasadena told the outlet: “There could be organisms floating in Titan’s atmosphere that essentially drink petrol to sustain themselves.”
Titan has long been considered a promising hunting ground for life in our solar system.
Europa, a moon of Jupiter, is also considered to be a potential breeding ground for alien life.
Nasa's latest rover will collect rocks that will be hurled back to earth for scientists to examine for signs of historic life.
