On which moon, or planet, do you think we will find alien life?

reply to post by game over man


There is much Titan has in common with earth, isn't there?

Try planet Earth!!

But the question is, there is life on Earth but is it intelligent life? Given our war mongering ways and the renewed threat of Cold War 2 and possibly nuclear war on the horizon, any visiting ET would despair and say no intelligent life exists. Just a bunch of overrated apes playing with dangerous toys.

If we had governments that weren't working against us we would already know the ETs are coming to this planet.

I think Mars.

Then they will find it in outer space in general.

After that they will say that life could be anywhere....

And then we will find out we are a dust particle.

I've had a free-floating, semi-informed intuition for quite a while that Callisto may have life within our solar system.

Callisto has the lowest density (1.86 gm/cm3) of the Galilean satellites. From recent observations made by the Galileo spacecraft, Callisto appears to be composed of a crust about 200 kilometers (124 miles) thick. Beneath the crust is a possible salty ocean more than 10 kilometers (6 miles) thick.

Callisto is about the size of Mercury.

I agree that I believe we will discover alien life, of proof there of, on earth before discovering it in the cosmos.

Oops ! My Bad . I Stand Corrected. Arthur C. Clarke must be Ashamed of me Right Now .......LOL

I think the clear frontrunner is Europa due to the potential of temperate oceanic conditions made possible by tidal flux. The possibilities now seem even greater with the potential discovery of debris originating from the impact of a comet or asteroid of the type that carries organic material. This would basically be the same manner in which scientists believe the earth was seeded with building block amino acids way back when.

put me in the Mars column.

even with the conditions that are there now.

life could have evolved to deal with the loss of atmosphere and mag field.

what looks like rocks could be protection for whatever life is still around.

underground?

lol, probably nothing bigger than a chicken!

Well I personally think that we have already found them, or they found us, but as far as just which moons exclusively I don't know, there was a movie out not too long ago about Europa where they found alien life but I'm not sure if it was backed by any scientific facts.

All of them, and the ones we don't know about, there are far more planets than we know of in the solar system and cities in space, the whole spectrum. Find them, probably black ops do, people don't get to, its all hidden except for little peaks under the curtain.

Most likely Europa, and then Enceladus too.

This is what I have thought also.. I have a feeling that every planet and moon will have signs of activity of intelligent activity having happened there.. Mars to me especially looks to be in ruins from some old civilization, maybe even humans.. I have seen so many things that aren't just rocks on mars and image manipulation too many times to think anything else..

The current psychological manipulation and how sociology works to create visible effects, just shouts out that there is tons we are not being told.

Our solar system probably has a history of activity that would read like an insane sci-fi-fantasy novel.... Just a gut instinct though..

There is a lot in common. With the thick atmosphere, we may discover much more once we have a clear view of the surface. I feel with the commonalities with Earth, especially the rain and atmosphere, there may be a type of rock/plant life. If something like that exist, well then creatures would have something to eat.

I'm kind of torn on this topic. I definitely don't think we are alone in the universe, but I think it's quite likely that Earth is the only planet harbouring life in out solar system.

My totally unscientific gut feeling is that life developing is by no means unique, but a sufficiently rare event that life arising independently on two bodies in one star system is pretty unlikely. It's like winning the lottery - there are thousands of lottery winners out there, but the chances of two of them having bought their winning tickets in the same store are fairly remote (not to say it never happens, of course!) There is still the possibility of "cross-pollination" between planets in the solar system, though.

Having said that, I am intrigued by the possibility of life on Europa and I would love to see some exploration of that moon in my lifetime. Although we would have to be very careful not to contaminate that environment.

i got sick from life on enchilada.

but seriously. you people are way out there.


do we know that anything can live, "way down by the methane sea" ? jimi hendrix.

europa with no sunlight?

bunch of shellfish. cool stuff.

reply to post by tsingtao

Well there is life on Earth that doesn't rely on sunlight, which draws its energy from geothermal vents deep under the sea where no light penetrates. Sure, it's not the kind of life you'd invite round for dinner, but if life is rare, you'd have to imagine intelligent life is going to be super-rare.

Despite all the movie-worthy "first contact" scenarios, I'm fairly sure the first verified sighting of extraterrestrial life in our solar system, if it does happen, will be by some scientist peering down a microscope or sifting through a bucket of ooze.

Titan or Enceladus (tied for 1st place). Europa third.

The ocean that is thought to be under the surface of Enceladus has the same salinity of Earth's oceans, plus organic compounds have been detected in that water (detected by Cassini as it flew through that water as it shoots from geysers into space).

Is it Snowing Microbes on Enceladus?



I would also put Titan at the top of that list, but it is more difficult to imagine life as we DON'T know it -- which would be what Titan would have (uses methane like water and breathes hydrogen). However, just because it is difficult to imagine, that does mean I don't think it could exist. It's just that it would be so different that the type of life that would exist there would be hard to imagine -- but it could still very well exist whether I can understand it or not.

The type of life on Enceladus is easier to imagine, because we already know that Earth-style life could possibly live there.

you are correct about the salinity and possible Enceladus water. Do they not think the same thing about Europas' water too? I think so. I totally agree with your thoughts about methane based life on Titan. It WOULD be life as we do NOT know it. I think there is lots of this type of life out there.

Possibly, but I was just going by direct hard evidence. The Cassini spacecraft was able to dip low enough into the geysers of Enceladus to directly "taste" (i.e., analyze) the water coming from under the surface of Enceladus with a mass spectrometer and found salty grains and organic compounds.

I don't know about any direct analysis of water from Europa. If Europa has the right mix of water-soluble minerals surrounding its oceans, then I suppose it could have similarly saltwater oceans, too.
