# Why is there so much methane in space?

In school I learned that methane is organic matter and that it is a possible product of crude oil refinement. However, recently I read that Uranus has huge methane storms and the Saturn moon Titan even has lakes consisting only of methane or ethane.

Now, I'm wondering, how does all that methane get out there?

Is it the result of organic processes or is it created in the cores of suns like other elements? Do we even know?

Methane is also a pretty complex material. Do we know sources of more complex molecules other than methane in such quantities? Except life on earth?

• I'm unclear of what specifically you're asking, because methane is one of the simplest molecules around. Since carbon is one of the most common elements in the universe (either by mass or by number), while hydrogen is number one, it's not too surprising that a lot of $\mathrm{CH}_4$ is around. Just like there's a lot of oxygen around, so $\mathrm{H}_2\mathrm{O}$ is common, too... – Stan Liou Mar 11 '15 at 2:21
• "Now, I'm wondering, how does all that methane get out there?" This is a fun question, how does it get out there?: Drill baby drill, I suppose! Hydrogen is the most common element in the world. Carbon is the third most common. It is not very unusual that they join to form methane, lying around having nothing better to do. – LocalFluff Mar 11 '15 at 5:37
