A few weeks ago I bought Brian Cox's Planet book for about 12 quid in Tesco. In it was this stunning photo taken from the Cassini mission to Saturn. It shows the moon Enceladus on the horizon of Saturn. To put it bluntly thats an alien moon over an alien planet. More astonishing was the text on Enceladus, To cut it short and not bore the non-science geeks, it is covered in glaciers, from these glaciers there are plumes of "something". To find out what they were Cassini took a detour and some samples, they contained Salt water with traces of organic compounds, which to a Biochemist/Biological means the precursor to life. Now comes the "thoughtful" part. Cassini was soon to run out of petrol (or whatever it ran on) to find out more the scientists could end its days on Encedadus, but they considered that this might present a danger to any life on the moon so crashed in into Saturn instead. Interesting how some people don't care much about the Earth's ecosystems whilst others will even care about those on another world. Well I was "gobsmacked" even if no one else is.
