Although the ground feels solid and immovable, in reality, all life on Earth is on the outside of an 8,000-mile-diameter ""spaceship"" that is twirling on its axis, speeding around the Sun, and sweeping around the galaxy. ""Earth's Journey Through Space"" explains how astronomers can tell that Earth is going through such gyrations and what dramatic effects those motions have on the planet. Highly visual and informative, this fresh new book also recounts how astronomers - beginning with the ancient Greeks - first discovered Earth's movements, and how new high-tech telescopes are now revealing much more about our place in the universe.
