If its dark enough, yes. Colors take concentration to discern but they're there. Best night skies are clear moonless nights. Best I have seen personally is in the YucatanCromat said:So I take it you can't really see these huge colored stars just hanging in the sky right? It seems unreal.

The sad unplugging of the Allen Telescope Array due to lack of funding brings a screeching halt, at least temporarily, to the most ambitious search for "hello" radio transmissions from E.T.
But perhaps it's time to simply think far outside of the box regarding our preconceptions of how to find extraterrestrial civilizations, says Clement Vidal of the Evolution, Complexity and Cognition group at the Vrije Universiteit Brussel. And, the most advanced aliens may be the easiest to find.
ANALYSIS: Cosmic Rebirth Encoded in Background Radiation?
Vidal's reasoning: The universe is so old there have to be far-advanced civilizations out there, billions of years more evolved than us. They have to be doing super-human engineering feats that are recognizable across intergalactic space. "Super-human" might also mean that the most advanced life-forms could very likely be post-biological. They have evolved far beyond being creatures of flesh and blood, as described in Arthur C. Clarke's "2001:A Space Odyssey."

I've not the time to check, but what do you mean "making shit up"?wolfmat said:He's just making shit up in that graph, so yeah. If you would've projected like that in the 1940s (or in 1969, for that matter), there would be other ridiculous outcomes. Let's see how this all goes down and then make some smart remarks about it, shall we?

I got that part.Mario said:I believe the data is likely to reflect actual numbers based on people landing on the moon, those people dying, and when those people might be likely to die (the latter, sure, probably made up).
This is what I'm not happy with. Anything might happen in the next 30 years. I wouldn't expect much happening in the next 10 in terms of landing on another body, so I won't contest the graph up to like 2020. But the next 30 are anybody's guess. It's not like spacefaring is an isolated endeavor, removed from society and its ups and downs.Mario said:The point (with the assumption we won't place a human on another world any time soon due to funding and projects being pulled) is that he is making a statement that without a vision and sustained investment, we aren't getting off this rock despite a brief flirtation with the concept.
That is why I was referring to those.Many projections from 1969 or even 1940 predicted many more "living humans that have walked on another world" by now. Heck, we were supposed to have colonised the moon by now.
I think you may have missed that that was exactly his point. Without a change, that is what will happen. If the current trend continues, that is where we will be. That is all he is saying, not that it is impossible that there will be another manned landing programme.wolfmat said:I got that part.

I don't think "anything's possible" is to be read out of the graph, but it's not really interesting what I think about it if he got his message with the "we need another vision" thing across to everyone else.Dead Man said:I think you may have missed that that was exactly his point.

making a guess here, but i believe the air bubbles would just float around in the ball of water, gently moving around inside. bubbles that bump into each other would merge to make a bigger bubble. if the bubble of air came to the surface it would escape into the surrounding atmosphere and the water ball would reform to account for the loss of volume.awesomeapproved said:Anyway, say you were in orbit, weightless, and have opened a container that contained water. You opened it so carefully that it bonded and stayed still.
If you managed to stick a tiny straw into it, and blew air into it, what would the bubble do? Would it stay right there as another blob? Would it somehow try to exit the water?
even with a heat source, i don't think liquid water can exist in space. the vacuum of space would make it disperse wouldn't it?awesomeapproved said:And then this - a REAL stretch of the imagination...
Are there ANY situations where you could imagine liquid water existing in space? I know it would need a heat source and something to regulate some of the pressures to prevent boiling too soon... I just can't get that concept out of my head. Imagine it. Anyone care to think about that with me - liquid water in a zone close to a star or other heat source?

need a real scientist to confirm, but i think that's what would happen.

Having never seen another habitable planet, I hope they are all as beautiful as ours.

A thin shell of ice formed by a continuous cycle of heating and freezing gives Haumea, a distant dwarf planet discovered in 2004, its distinctive glimmer in deep space.
Astronomers knew Haumea had a frosty coating, but they didnt know it was made of fresh, highly organized crystals instead of old, amorphous glass-like ice.
Since solar radiation constantly destroys the crystalline structure of ice on the surface, energy sources are required to keep it organized, said planetary scientist Benoit Carry of the European Space Agency in a press release May 12. The findings have been accepted for publication in Astronomy and Astrophysics.
Named after the Hawaiian goddess of childbirth, the rocky, football-shaped Haumea is one-tenth the size of Earth and about 43 times farther from the sun, located beyond Pluto in the Kuiper belt.
By analyzing sunlight bouncing off Haumeas surface with the Very Large Telescope in Chile, Carry and other astronomers calculated that its surface ice is constantly replenished. They think heat from radioactive elements, combined with gravitational kneading from its two tiny satellite bodies Hiiaka and Namaka, melts ice on Haumeas surface. It soon refreezes, resulting in a perpetual cycle of icy renewal.
Another area of fascination for astronomers is a dark, reddish spot on Haumeas surface. Irradiated minerals or organic matter may cause the discoloration.
Astronomer Pedro Lacerda of Queens University in Belfast said in the press release that it may be an especially rich source of crystalline water ice, a fountain for Haumea.
