Where do you go for the real low-down on astrobiology, astronomy and the physics of spaceflight? I’m not averse to using Wikipedia, but only until I discover a better specialist resource – and one has cropped up, in the form of David Darling’s online encyclopaedias. Over 10,000 entries, updated daily to keep up with the latest research and discoveries, plus articles on sustainable living and alternative energy – that’ll keep me busy for a few weeks.
