Tropical Lakes On Saturn Moon Could Expand Options For Life

Absolutely positively evidence that the universe was crawling with life!

It would mean life is not only not based on DNA (and thus couldn't be a result of cross-contamination with earth as has been suggested might be the case for any Maryian life we might come across), but wouldn't even be based on WATER! It would mean that perhaps anywhere there was a liquid at perhaps almost any temperature we should be on the lookout for life! (Liquid helium on Pluto? Molton magma in the earth's mantle?)

I read in the book "Life as we do not know it" that Titan could be the home to up to three(!) completely separate "Domains" (the authors term) of life. Water based (around some heated cryo-volcanoes perhaps), ammonia-water, and methane based.

Someday we'll send a manned mission to orbit Titan. Then using remote balloons(!) and boats(!) they'll be able to really investigate these possibilities. Until then, the time lag will make things difficult (but not impossible I hope).
