From earliest times, humans have wondered about the sky above them. Simple telescopes in the 1600s made possible descriptions of the wonders of Earth's Moon and the closer planets. It took the development of powerful telescopes and modern space probes to learn more about the more distant planets—Jupiter, Saturn, Uranus, and Neptune. In this book, we'll explore seven wonders of these four enormous planets—called the gas giants—and their moons. On Saturn, we'll examine its amazing rings and their properties. On Jupiter, we’ll investigate the Great Red Spot—a gigantic storm about twice the size of Earth that has lasted for centuries. We’ll also explore a moon of Jupiter with erupting volcanoes, a moon of Uranus covered with one of the weirdest landscapes in the solar system, a huge crater on a tiny moon of Saturn, as well as planet auroras much more spectacular than Earth's northern lights. We'll also consider how the discovery of water on Jupiter's moon Europa may mean that life is possible in other worlds.

Describes the geographic phenomena of the inner planets of the solar system and their moons, including the largest mountain of the planets, the deepest canyon, and the highest recorded temperatures.

From earliest times, humans have looked to the sky in wonder, and their wonder and curiosity fueled science. Ancient peoples built enormous temples and monuments to observe the sun and track the movement of stars. And as scientific knowledge expanded, technologies grew more sophisticated. Each development changed the way we viewed our place in the universe. But no technology changed our understanding more than the ability to launch scientific equipment—and human explorers—into space. In this book, we'll explore seven wonders of space technology. Scientists and engineers have built vehicles and equipment to explore the farthest reaches of the solar system. Orbiting satellites and telescopes have given us everything from more accurate weather reports to glimpses back to the beginning of the universe. International teams have built an orbiting space laboratory and are working on plans for human lunar settlements and missions to other planets. Learn about the people and the science behind these amazing advances in space technology.

From earliest times, humans have wondered about the sky above them. People looked at distant stars and wondered what they were made of. They wondered whether any other places in the universe were like Earth. At first people used simple telescopes to study the solar system—the Sun and all the planets that circle around it. Later, more powerful telescopes and high-tech machines allowed people to investigate worlds outside the solar system. In this book, we'll explore seven wonders beyond the solar system. We'll look at giant clouds of gas and dust called nebulae. Some nebulae are places where stars are born. Other nebulae are all that remains of stars that have died. Other wonders beyond the solar system include pulsing stars, giant stars, and giant clusters of stars called galaxies. We'll visit them all. And we'll explore the age-old question: Does the universe have any other planets like Earth? We'll learn about scientists who hunt for Earthlike planets and the tools they use. Finally, we'll look at the big picture—the universe itself. This vast network of stars, planets, and other objects is the biggest wonder of them all.

Presents information about the asteroids, comets, and meteors found in the solar system, describing their physical components, orbits, and the effects of their possible collisions with the Earth and other planets.

Have you ever wondered how stars are born? Or what happens inside a black hole? Or how to safely view a solar eclipse? This book tells you the answers—and much more. See what astronomers and space scientists have discovered about the amazing wonders of the stars.

The universe is full of space phenomena, such as dark matter, dark energy, and the beginning of the universe. Read what astronomers and space scientists have discovered about these amazing wonders—and what they have yet to learn.
