After watching Prometheus (an excellent visual experience!) I was drawn yet again to ideas of the origins of life on Earth. The film purports the idea of panspermia whereby another humanoid race brought life to our planet. This got my brain thinking about an article I’d read previously related to astrobiology, specifically the search for habitable life outside our planet: http://www.bryanappleyard.com/planet-hunting/
This is not a new idea but are we getting closer to finding life outside out planet? Perhaps we may never know:
