Embark on an exciting and educational tour of the cosmos in this information-packed guide -- from the first few seconds after the Big Bang to the remote-controlled Pathfinder expedition to Mars and beyond. The journey begins with an introduction to space exploration and humanity's relationship with the stars, from the astronomers of the ancient world, to the day-to-day work of orbiting satellites. Next is a tour of our own solar system, the Milky Way, and Galaxy: atmospheric planetscapes reveal the frozen methane seas of Pluto, while the carefully timed trajectory of the Voyager Probe provide stunning pictures from Jupiter, Saturn, Uranus, and Neptune. Full color photographs and computer-generated illustrations are carefully balanced with a succinct, informative text to provide curious young astronomers with a far-ranging understanding of the Universe. This cutting-edge guide is a visual and educational treat for children ready to seek the outer limits of their imaginations. Also includes a highly accessible factfile and glossary.
