By the way, it's already a month old, there's nothing new since Cassini's last trip.

Also, can't believe Newsweek did a mistake like that if not for clicks...

"Update: An earlier headline read that signs of life were found on Enceladus. We regret any misunderstanding this headline may have caused. NASA has discovered that Enceladus is habitable, not inhabited."

So there's this big hydrogen vent in a moon of Saturn. Where's the energy coming from to drive that? Too far from the sun. Enceladus is tidally locked to Saturn, so there are no tidal forces. Enceladus has very low orbital eccentricity, a near-circular orbit, so there are very low tidal forces from that. Some phenomenon must provide energy for the hydrogen jet.

Wow. Maybe basic transport is not the first area where intelligent machines will make their human counterpart superfluous. I'm sure machines can do better than this.

Couldn't it just be pressurised hydrogen?

This article seems written to sound as spectacular as possible while hiding anything that might lead to real understanding.

"Habitable" makes it sound like we could move there and live there without too much trouble. That's not true. What has been discovered is that microorganisms might be able to live there, near hydrothermic vents that seem to create free hydrogen, which could support primitive life. That life could be similar to life living around hydrothermic vents on the bottom of the Atlantic Ocean. No sign of life itself, though, just a process that could theoretically sustain life without requiring sunlight.
