Dean Regas has been the astronomer for the Cincinnati Observatory since 2000. He's a renowned educator, author, and national popularizer of astronomy.  The science of space and space travel is something we're hearing much more of nowadays and in various forms. While that is still the area of a select few, Dean's new book in collaboration with National Geographic "1000 Facts About Space" is a way we all can experience the thrill vicariously.
