I have worked on sprucing up some global views of Europa from Galileo. There are a few more global views I hope to get to eventually. But the best two at nearly full phase benefited a lot.
[Moderator note: There are several more threads containing Galileo Europa images but they all contain several inactive image links.

If you try the CICLOPS site and use their new search feature for "Europa" a couple of nice (if small) color images will pop up.

This could bode well for life on Europa (and Enceladus?):
Scientific American, 30 September 2005 http://www.sciam.com/article.cfm?chanID=sa...A8E83414B7F4945 Geologists have produced evidence of abundant marine life on the earth from a period when others say a thick layer of ice gripped the entire planet. The find lends considerable support to one side of a scientific controversy that has been widely debated for decades. The hullabaloo is over a glacial period dating to about 750 million to 600 million years ago. Experts agree about the presence of ice on the planet then--even at the equator--but how much and to what extent is still up in the air. Theories range from a "snowball Earth" hard packed in kilometer-thick ice to a "slush ball Earth" characterized by thin ice and areas of open water. The range of conditions would have impacted the microorganisms present. Thick ice would have made life difficult for plants and animals, one line of reasoning goes, choking oxygen out of the sea and blocking sunlight needed for photosynthesis. Mass extinction would ensue and after the thaw, give rise to an explosion of multicellular life. -------------------- "After having some business dealings with men, I am occasionally chagrined,
and feel as if I had done some wrong, and it is hard to forget the ugly circumstance. I see that such intercourse long continued would make one thoroughly prosaic, hard, and coarse. But the longest intercourse with Nature, though in her rudest moods, does not thus harden and make coarse. A hard, sensible man whom we liken to a rock is indeed much harder than a rock. From hard, coarse, insensible men with whom I have no sympathy, I go to commune with the rocks, whose hearts are comparatively soft." - Henry David Thoreau, November 15, 1853 |
