Two potential signatures of life on Saturn's moon Titan have been found by the Cassini spacecraft. But scientists are quick to point out that non-biological chemical reactions could also be behind the observations.

Titan is much too cold to support liquid water on its surface, but some scientists have suggested that exotic life-forms could live in the lakes of liquid methane or ethane that dot the moon's surface.

In 2005, Chris McKay of NASA's Ames Research Center in Moffett Field and Heather R Smith of the International Space University in Strasbourg, France, calculated that such microbes could eke out an existence by breathing in hydrogen gas and eating the organic molecule acetylene, creating methane in the process.

This would result in a lack of acetylene on Titan and a depletion of hydrogen close to the moon's surface, where the microbes would live, they said.

Now, measurements from the Cassini spacecraft have borne out these predictions, hinting that life may be present.

They are going to invade and steal all our welding gas cylinders for their orgies!

If they create methane as a by product of consuming other chemicals, it must smell really nice up there.

I wonder if they light their farts?

You post an out of this world thread , you will get out of this world answers.

but to be truly happy one must fart in the presence of a lady. And then after the toot look at her with distain.

Plus, if they grow acethylene for food, and breathe hydrogen - I think they know better then light a fart!!  

Girls don't fart.       They fluff.

Hey why fart and waste it when you can belch and taste it . We can find a gutter even in outer space
