With the end of fossil fuels looming over the horizon and a glumness about the states of economy our attention has returned star ward. This time it's being looked at in a more serious manner, as both a destination and a place to discover. With things like the X-Prize, privet wealth and imagination are driving a push to space. It is now no longer only the hands of governments to choose when and how we go.
Since the 90's life has been discovered on earth in the most inhospitable environments; like in caves 2miles beneath the earths surface where microbes live in and produce sulfuric acid, in fact there is so much organic energy in some of these caves strange fish swim in Ph 0 fluid. Or 10 foot tube worms living around hydrothermal vents 8 miles under the Atlantic ocean, where also small bacteria use a process (in absolute darkness) called kemosynthesis to make energy in a Ph of 11. Or the bacteria living in the lakes under the frozen antarctic. However these most extreme environments represent a pleasant average of other worlds.
I personally feel life is a natural progression of the complexification of matter (ie. hydrogen> helium) and intelligence follows on from that. But then i am a tooth fairy agnostic. What i wonder then is how will theological dogma on creationism hold up to the seeming inevitably of finding life everywhere we look hard enough.
