Features: Engaging sidebars highlight important space discoveries Timelines illustrate the ways our knowledge of space has changed over time Glossaries explain difficult scientific terms in a way that makes them easy to understand Eye-catching images give readers an up-close look at the far reaches of space www.factsfornow.scholastic.com

"Discusses the planet Neptune, including observations by ancient cultures, current knowledge of Neptune, and plans for future scientific research and space exploration"--

Hugo Award winner Ben Bova continues his grand tour of the human settled solar system with a fan-pleasing look at life in the Outer Planets, among the moons of Neptune. In the future, humanity has spread throughout the solar system, on planets and moons once visited only by robots or explored at a distance by far-voyaging spacecraft. No matter how hostile or welcoming the environment, mankind has forged a path and found a home. In the far reaches of the solar system, the outer planets—billions of miles from Earth, unknown for millennia—are being settled. Neptune, the ice giant, is swathed in clouds of hydrogen, helium, and methane and circled by rings of rock and dust. Three years ago, Ilona Magyr’s father, Miklos, disappeared while exploring the seas of Neptune. Everyone believes he is dead—crushed, frozen, or boiled alive in Neptune’s turbulent seas. With legendary space explorer Derek Humbolt piloting her ship and planetary scientist Jan Meitner guiding the search, Ilona Magyr knows she will find her father—alive—on Neptune. Her plans are irrevocably altered when she and her team discover the wreckage of an alien ship deep in Neptune’s ocean, a discovery which changes humanity’s understanding of its future...and its past.

The Neptune File tells the story of the gifted mathematician John Couch Adams and the discovery of the planet Neptune in 1846. Combining scientific triumph with international controversy, this is an intriguing tale of the search for an unseen planet, and the uproar it caused. More than just an intriguing historical yarn, Adam's work signified the beginning of a new era of planet hunting by providing astronomers with a powerful tool with which to search for new worlds. It marked the genesis of the idea that astronomers could find new planets by looking for their telltale gravitational influence on other bodies, rather than observing them directly with telescopes. In recent years this approach has led to an extraordinary series of discoveries - today's planet detectives are relying on a technique whose theoretical foundations were laid by their nineteenth-century predecessors.

Describes the characteristics of the three most distant planets in the solar system--Uranus, Neptune, and Pluto.
