Semi-related...

SM, or any of you space jockey, uber outer-orbital knowledgable badasses. Recommend me a good moon globe. I got a nephew that is all of a sudden interested in the moon, and has a birthday comming up.

PM me if you'd like to keep the thread on track.

Don't know, sorry.

How old is he?  Depending on how old he is, I can't recommend a From The Earth To The Moon DVD box set highly enough.  If he's a bit younger, maybe get him a telescope?

He'll be 9. Way to smart for his age. He's always looking at my Earth Globe, and just started talking about the moon while he does it. It got to thinking about a Moon Globe. I looked up a couple on the interwebz, but I dunno how accurate they might be.

DVD's might be OK, but I worry he moght scratch them or what not, same with the telescope. When I was 9, I could break a crowbar damn near.

I found this one, yes it is a bit pricey, but mother and me will split it.

EDIT/MOD: Starting to find the same one for sevral bucks cheaper at other sites. Still the same globe though. Just at a better rate.

Very cool indeed. So does this mean that liquid water may be more abundant in the universe than we thought, or, is water in our solar system a unique anomaly?

Even in our own Solar System it's a big deal.

As are the monsters that no doubt live in this ocean (Clarke maybe have got the wrong moon).

Absolutely! But, if man has found it so, relatively, close-to-home does it make it that much less significant? For decades the thought of finding water somewhere else in the universe other than on Earth was akin to finding the pot of gold at the end of the rainbow... now we've found it in our own solar system... If it is in fact water on that moon does that not mean finding water elsewhere in the galaxy/universe is just about a given?

I'm not actually surprised water has been found, to be honest. I mean the laws of physics and chemistry don't just apply to Earth. Water must exist elsewhere in the universe. It must! I'm sure there are other planets with full ecosystems that exists elsewhere in the universe. It's just too vast for us to be an anomaly. As I've said before if Earth was the epitome of the developed universe why would it be so expansive? Overkill for nothing, no?

Yes the law of averages would suggest that since there's water in our system, it's elsewhere.  But there's a hell of a lot of things that have to fall into place go from having water to having lifeforms.  On the other hand, they've found lifeforms living around volcanic vents underwater.  That sort of thing would bode well for finding life in circumstances that are just as extreme.

Haven't they speculated that water exists on Europa (one of Jupiter's moons) as well? Before this discovery, I had read somewhere that Europe was the next likeliest place within our own solar system for water and maybe life.

Yep.  They've been speculating about a mission there to try and drill through the ice to the sea believed to be underneath.

Wow!  Very interesting, SM!

(And I'm pretty interested in the idea of the plumes kicking up possible life precursors - or even life - out into space.  Panspermia!)

Yes, extremophiles, I believe they are called.

The video in SM's link is gone now, but here are some articles I found on the same subject:

Yes, extremophiles, I believe they are called.

http://en.wikipedia.org/wiki/Extremophile Their existence really backs up theories of life existing elsewhere than earth. If these crazy guys can exist here, what kind of even more extreme organisms can live elsewhere?

Months ago, I think it was Deez posted about this guy:
