Renowned science writers John and Mary Gribbin team up with one of the most historic scientific sites in the world--the Royal Observatory, Greenwich--to take readers on a stunning visual tour of the universe. This riveting journey moves from our home planet outwards to the Moon, Sun, Inner and Outer Solar Systems, Milky Way, and other galaxies. Not only do the Gribbins discuss the always-intriguing topic of alien life, but they divulge little-known facts (Venus is the only planet in our solar system to rotate backwards), as well as all the basics beginning armchair astronomers need to know. Dramatic four-color photographs complement the informative text, giving readers a sense of what it might be like to be an astronaut...and go where no one has gone before.
