An astonishing exploration of planet formation and the origins of life by one of the world’s most innovative planetary geologists. In 1959, the Soviet probe Luna 3 took the first photos of the far side of the moon. Even in their poor resolution, the images stunned scientists: the far side is an enormous mountainous expanse, not the vast lava-plains seen from Earth. Subsequent missions have confirmed this in much greater detail. How could this be, and what might it tell us about our own place in the universe? As it turns out, quite a lot. Fourteen billion years ago, the universe exploded into being, creating galaxies and stars. Planets formed out of the leftover dust and gas that coalesced into larger and larger bodies orbiting around each star. In a sort of heavenly survival of the fittest, planetary bodies smashed into each other until solar systems emerged. Curiously, instead of being relatively similar in terms of composition, the planets in our solar system, and the comets, asteroids, satellites and rings, are bewitchingly distinct. So, too, the halves of our moon. In When the Earth Had Two Moons, esteemed planetary geologist Erik Asphaug takes us on an exhilarating tour through the farthest reaches of time and our galaxy to find out why. Beautifully written and provocatively argued, When the Earth Had Two Moons is not only a mind-blowing astronomical tour but a profound inquiry into the nature of life here—and billions of miles from home.

For centuries, astronomers have placed a special interest on the other planets of the solar system. But with the advent of spacecraft and the tremendous missions undertaken by the Voyager and Cassini probes, astronomers have discovered that the natural satellites of the planets—the solar system's moons—are some of the most extraordinary places imaginable. There are moons with towering geysers, erupting volcanoes, and subterranean oceans of warm, mineral-rich water. Some of the highest mountains and deepest canyons can be found on the moons. There are moons that have shattered into pieces and then reassembled. There is even a moon where it rains rocket fuel. Recently, scientists have turned to the moons for answers in their investigations of the origins of the solar system and the evolution of life on our own planet. Featuring full-color, scientifically accurate illustrations by NASA artist Ron Miller, Natural Satellites: The Book of Moons chronicles these investigations and the questions we have yet to answer in our exploration of the solar system's moons.

The increase in our knowledge of the solar system during the five years since the author last revised this book (1963) greatly exceeds that in the previous two decades. The program of the U.S. National Aeronautics and Space Administration and the space program of the U.S.S.R. have been prime contributors to this rapid progress, but the impetus has carried over to groundbased studies of the Moon and planets as well. The advances in radio and radar astronomy alone are striking, and are continuing at an accelerating pace. This third edition of Mr. Whipple's popular and authoritative book is thoroughly revised in light of this new knowledge. The most extensive revisions are in the chapters on the Moon, Mars, and Venus--the members of the solar system on which the various space programs have concentrated. The author has included many new and dramatic illustrations in this third edition, among them photographs taken from U.S. and Russian space craft. There are striking photographs of the Moon, with close-up views of its surface texture, pictures of Mars taken from Mariner IV, and radar pictures of Venus that "see through" that planet's obscuring cloud layer. The book is written in nontechnical language and with a lucid, witty style that is readily understandable to the interested layman. Mathematics has been avoided, and scientific methods and processes are described in simple terms. In presenting the latest information about the planets and their moons, Mr. Whipple discusses their origin and evolution, motions, atmospheres, temperatures, surface conditions, the environment essential for life as we know it, and the possibilities of life outside the Earth. He concludes with a discussion of current theories about the origin of the solar system.

Can we detect the moons of extrasolar planets? For two decades, astronomers have made enormous progress in the detection and characterisation of exoplanetary systems but the identification of an "exomoon" is notably absent. In this thesis, David Kipping shows how transiting planets may be used to infer the presence of exomoons through deviations in the time and duration of the planetary eclipses. A detailed account of the transit model, potential distortions, and timing techniques is covered before the analytic forms for the timing variations are derived. It is shown that habitable-zone exomoons above 0.2 Earth-masses are detectable with the Kepler space telescope using these new timing techniques.

This book captures the complex world of planetary moons, which are more diverse than Earth's sole satellite might lead you to believe. New missions continue to find more of these planetary satellites, making an up to date guide more necessary than ever. Why do Mercury and Venus have no moons at all? Earth's Moon, of course, is covered in the book with highly detailed maps. Then we move outward to the moons of Mars, then on to many of the more notable asteroid moons, and finally to a list of less-notable ones. All the major moons of the gas giant planets are covered in great detail, while the lesser-known satellites of these worlds are also touched on. Readers will learn of the remarkable trans-Neptunian Objects – Pluto, Eris, Sedna, Quaoar –including many of those that have been given scant attention in the literature. More than just objects to read about, the planets' satellites provide us with important information about the history of the solar system. Projects to help us learn more about the moons are included throughout the book. Most amateur astronomers can name some of the more prominent moons in the solar system, but few are intimately familiar with the full variety that exists in our backyard: 146 and counting. As our understanding of the many bodies in our solar system broadens, this is an invaluable tour of our expanding knowledge of the moons both near and far.
