Here's an idea. Build a few (rather thick) Plexiglas domes (or something similar) to house cities or small towns--otherwise just hold the cities within close vicinity of the geothermal vents?

It's Europa. Check this out:
I think that the bold points make it habitable for human life-I mean, Europa has oxygen and water-just what humans and other organisms need to live on Earth!
But then again, it has a temperature of 102 K, which is approximately -171 degrees Celsius, or -275 degrees Fahrenheit(correct me if I'm wrong).
There's also the distanse factor to consider as well.
Someday...

But it also orbits within a major radiation belt of Jupiter, that would kill unshielded human life instantly.

Eegh..I didn't know that...
But if civilization was protected by something (say a dome), could life there be feasible?

[Siguy]

Perhaps a lead dome...

Perhaps a lead dome...

But no scenery?
Seriously, is life sustainable somewhere else in the solar system?

Isn't there another material that can reflect radiation?

[Siguy]

Pretty much any material will shield radiation in someway, if it is thick enough. Lead is extremely dense and heavy, so it blocks all types of radiation easily. But with Jupiter, we're talking massive amounts of radiation in its radiation belts.

If you're worried about radiation, buy some lead blocks from your friendly neighborhood United Nuclear.

In my opinion, Saturn's moon, Titan, is the most Earth-like in the Solar System. Sure, it has a thick atmosphere, low gravity, cold climate, and it is a moon, but methane on Titan is very much like water on Earth. There are seas of liquid methane, clouds of methane vapor which rain down liquid methane, and methane ice in cold spots.

If only there were oxygen, that thing would go boom in a heartbeat

Kind of a revival, but here:

Why did we let this thread go?
Unblemished Sun
Could this be a cause of weird weather?

[Russ]

What do you want to bet it will be held responsible for global warming?

[Rocksfan13]

Somehow I doubt that. Sunspots are a colder area on the Sun, so it should have the reverse effect.

[Siguy]

Interestingly, looking at a chart, right after 1954 there was a surge in sunspot activity, so that means that perhaps we could have a large amount of activity in a couple years.

It might have something to do with global warming, there was less activity during the little ice age and there has been an increase since (I think there must be a wider cycle), but it certainly isn't the cause.

[Siguy]

I forgot to post about it, I'm sure some of you have heard about the small asteroid 2008 TC3 which exploded over Sudan two days ago? Very interesting, it was actually the first object predicted to impact before it actually did. Sure it was small, and only discovered 20 hours before impact, but perhaps in the near future we will have a working Spaceguard system.

Now if only it had hit President Omar Hassan Ahmad al-Bashir.

[Rocksfan13]

Yes, I did happen to read about that.

20 hours is certainly not long enough. Although it was only the smallest thing, kinda makes you wonder what if it would have been much larger.
20 hours would not have given us enough time for anything except tucking our heads between our legs and kissing our butts goodbye.
