I figure that there are far more habitable moons than planets. Just having a gas giant and its children in the habitable zone... (which I always feel is a creation of our earth centric POV btw) opens dozens of possibilities.

But it is good to see science continues to catch up to sci-fi...

It's important to keep in mind that being in the so-called Goldilocks zone does not guarantee a habitable planet.  Three astronomers discussed this very fact on NPR earlier this week.

On the other hand, being outside of the zone does not necessarily rule out the possibility of life of some sort.

The moon is in the 'goldilocks zone'.  Selenites are conspicuous by their absence.

I think any world is worth exploring - even the moon.
