Evidence of Hydrothermic Vents on Enceladus

So apparently there was an announcement that 1% hydrogen gas was detected in the water geysers on Enceladus. Since water doesn't spontaneously break up into hydrogen and oxigen, something must be constantly adding more hydrogen gas to the water under the ice. And the prime candidate for that would be hydrothermic vents on the bottom of the ocean, like we have on Earth.

Not only are hydrothermic vents on Earth populated by lots of mycrobes that use the hydrogen and warm water as an energy source to live, it also seems to be a quite popular hypothesis these days that life on Earth didn't start in puddles on the coast lines but at these vents at the bottom of the ocean.

This would make Enceladus "habitable", in a certain sense of the word.

There was also evidence of methane, which confirms a source of carbon as well. There's a lot of great chemistry you can do with hydrogen, oxygen, carbon, and heat.

Here's the actual study, if anyone wants the science behind that Wired article. (Or doesn't feel like reading an article that starts by calling us "space nerds.")
