Originally posted by scottishinnzProbably helps but what about planets or moons like Titan or Europa, where there are oceans maybe way way under ice, no possible atmosphere, if a hundred years from now probes there find life, it would be hard to see how an isolated ecology could arise from panspermia, if you have 20 miles of ice on top of your ocean it would seem to severly limit access to the outer universe where microbes could rain down. I guess some kind of asteroid could penatrate all that ice though.
Well, ON ANY-BODY, might be closer. Although a body with an atmosphere probably helps.
I am kinda buying in to the panspermia idea but right now we only have a sample of one so the jury is for sure, out.
