Space Artist Brings 'Alien Worlds' To Life

David Aguilar's office at the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts, is a lot like any office in the building — except it's full of aliens.

Aguilar is director of public affairs and science information there and in his latest book for young scientists, "Alien Worlds: Your Guide to Extraterrestrial Life," he takes information about real exo-planets that are in an orbit around stars that might be able sustain life, throws in a little imagination to fill in the spaces and dreams up what kind of plants, animals and other things might live there.

Here & Now's Robin Young pays him a visit to talk about the worlds he's created.
