I almost missed it, but today, May the Fourth, is Star Wars day (get it?). There isn't much real science in the movies, but what I find pretty cool is that the novels, games and official magazines and guides have worked out the a biology of the aliens, ecology of the planets and other official minutiae of the Star Wars universe in detail.
Wookieepedia has the best collection of all this information. There you can follow in the footsteps of Iyra sentientologist Tem Eliss, and explore the rich biology of the galaxy's sentient species, semi-sentients, and other creatures. I find browsing through the wiki at least as entertaining as Episodes I-III!
