Author Topic:   Life in this Solar System?

Famous Eccles posted 06-10-99 05:09 PM ET
Any ideas. It seems that life first started on Earth around 3.9 billion years ago. (while it was still a bit molten, if you believe the stellar accretion theory) that means that life must be able to survive in a wide range of conditions.
Europa, seems quite likely, if enough light can get thru, or there are geothermal vents, and if it was hot enough for the original 'bag' of chemicals to form.
What about that metor from Mars? The one with spore shells on it, at least thats what they thought it was.
There is a theory for silicon and sulphur based life forms, as they would somehow work as a synthesis for carbon and water. (I will look it up).
Any ideas
no smartarses with 'there is life; on Earth!'

I think it's quite likely that Mars had life at one point. And I agree with Europa too. Read either 2061 or 3001 for a good look at it. Sulfur-based lifeforms, mostly.
There were also those floaters in Jupiter's atmosphere, and some possibilities of life on Titan. Guess we'll find oot in four years.

I think you got the title right this time. Similar to the other thread. but I'll to with yes.

Some of the microorganisms that live around the earth are tougth enougth to survive on Mars or in Jupitor. Anything is possible.

I misread the post. I thought it was a question. I read some stuff about the conditions on Europa. Seems like a good possibility. Mars probably had some life a long time ago.

I think you will find Jupiter is far drier and has more toxic ammonia than was thought when the 'Life on Jupiter' theories were espoused.
Titan, I think prehaps too cold.
I doubt any known existing life would survive Mars now. The nearest comparison (dry antarctic plains) is warmer, more water rich, has a denser atmosphere, much less UV, and the rocks are not toxic.

Nope, not here in Oxford, anyway.
