Aguilar, space artist extraordinaire, shows readers what creatures living on extrasolar planets might be like, in his National Geographic children's book "Alien Worlds: Your Guide to Extraterrestrial Life." Here he describes the process of applying real-world astronomy, biology and chemistry to imagine what life we might find on distant planets.
