I have been fascinated with the prospect for life on Jupiter’s moon Europa since I first heard about it as a child. But I have just one question: what kind of life? When I was a child, I thought they might have meant human-like life. Of course, I now realize that ever primitive bacteria would qualify for life by the people who claim there might be life there (NASA, I believe).
I guess what I am trying to ask is exactly how big could the animals be on Jupiter’s moon (as I’ve said, I now realize human-like life is probably out of the question)? Are we talking about a dinosaur-type life? Or in fact is bacteria basically what is meant by “life” here. If anyone has a link, that would be very helpful.
