David Levy has held a lifelong passion for comets, and is one of the most successful comet discoverers in history. In this book he describes the observing techniques that have been developed over the years--from visual observations and searching, to photography, through to electronic charge-coupled devices (CCDs). He combines the history of comet hunting with the latest techniques, showing how our understanding of comets has evolved over time. This practical handbook is suitable for amateur astronomers, from those who are casually interested in comets and how to observe them, to those who want to begin and expand an observing program of their own. Drawing widely from his own extensive experience, Levy describes how enthusiastic amateurs can observe comets and try to make new discoveries themselves. David H. Levy is one of the word's foremost amateur astronomers. He has discovered seventeen comets, seven using a telescope in his own backyard, and had a minor planet, Asteroid 3673 Levy named in his honor. He is best known as the co-discoverer of the famous 1994 Shoemaker-Levy 9 comet. Levy is frequently interviewed in the media and succeeded Carl Sagan as science columnist for Parade magazine. He has written and contributed to a number of books, most recently David Levy's Guide to the Night Sky (Cambridge, 2001).

Meteors occur when a meteoroid, a speck of dust in space, enters the Earth's atmosphere. The heat generated when this happens causes the surrounding air to glow, resulting in 'shooting stars'. During the most spectacular meteor storms larger particles give rise to fireballs and firework-like displays! Meteors are a delightful observing field - they do not require a telescope, and they can be seen on any clear night of the year, even in bright twilight. It was the sight of a single meteor that inspired David Levy to go into astronomy, and in this book he encourages readers to go outside and witness these wonderful events for themselves. This book is a step-by-step guide to observing meteors and meteor showers. Any necessary science is explained simply and in clearly understandable terms. This is a perfect introduction to observing meteors, and is ideal for both seasoned and budding astronomers.

When can you see fireballs and who should you contact if you spot one? When is it best to hunt for comets and meteors and whereabouts? How do you gauge the size of the coma in the head of a comet and estimate its degree of condensation? Clear and easy to use, this guide shows you how to make successful and valuable observations and records of comets, asteroids, meteors and the zodiacal light. For each topic the historical background and current scientific understanding support a wealth of observational techniques. Comet observers are shown techniques for search and discovery. They can learn how to make visual estimates of brightness and size, and how to make photographic studies of cometary heads and tails. Asteroid hunters will find a 'life list' of quarry and guidelines on how to search for these objects and then how to photograph or electronically image them. Fruitful photographic and electronic methods for studying meteors and meteor showers are provided. Visual and photographic techniques show you how to examine the often elusive zodiacal light. The more adventurous are provided with advanced techniques on how to make successful astrometric, spectroscopic and electronic observations. This is rounded off with an invaluable list of centres world-wide to contact with your details of unusual sightings.

It was a lucky twist of fate when in the early1980s David Levy, a writer and amateur astronomer, joined up with the famous scientist Eugene Shoemaker and his wife, Carolyn, to search for comets from an observation post on Palomar Mountain in Southern California. Their collaboration would lead to the 1993 discovery of the most remarkable comet ever recorded, Shoemaker-Levy 9, with its several nuclei, five tails, and two sheets of debris spread out in its orbit plane. A year later, Levy would be by the Shoemakers' side again when their comet ended its four-billion-year-long journey through the solar system and collided with Jupiter in the most stunning astronomical display of the century. Not only did this collision revolutionize our understanding of the history of the solar system, but it also offered a spectacular confirmation of one scientist's life work. As a close friend and colleague of Shoemaker (who died in 1997 at the age of 69), Levy offers a uniquely insightful account of his life and the way it has shaped our thinking about the universe. Early in his training as a geologist, Shoemaker suspected that it wasn't volcanic activity but rather collisions with comets and asteroids that created most of the craters on the moon and most other bodies in the solar system. Convincing the scientific community of the plausibility of "impact theory," and revealing its power for penetrating mysteries such as the extinction of the dinosaurs and the timing of the Earth's eventual demise, became Shoemaker's mission. Through conversations with Shoemaker and his family, Levy reconstructs the journey that began with a young geologist's serious desire to go to the moon in the late1940s. Sent by the government to find a way to harvest plutonium, Shoemaker instead found evidence in desert craters for what became his impact theory. While he never became an astronaut, he did become the first geologist hired by NASA and subsequently set the research agenda for the first manned lunar landing. After a series of victories and setbacks for Shoemaker, the collision of Shoemaker-Levy 9 with Jupiter provided the most convincing proof to date of the role of impacts in our solar system. Levy's explanation of the scientific reasoning that guided Shoemaker in his career up to this dramatic point--as well as his personal portrait of a man who found white-water rafting to be an easy way to relax--sets these fascinating events in a human scale. This biography shows what Shoemaker's legacy will be for our understanding of the story of the Earth well into the twenty-first century.

In this simple guide, David Levy inspires readers to experience the wonder of eclipses and other transient astronomical events for themselves. Covering both solar and lunar eclipses, he gives step-by-step instructions on how to observe and photograph eclipses. As well as explaining the science behind eclipses, the book also gives their historical background, discussing how they were observed in the past and what we have learned from them. This personal account contains examples from the 77 eclipses the author has witnessed himself. The guide also includes chapters on occultations of stars and planets by the Moon and of asteroids by stars, and the transits of Mercury and Venus. Tables of future eclipses make this invaluable for anyone, from beginners to practised observers, wanting to learn more about these fascinating events.

David Levy brings these "ghostly apparitions" to life. With fascinating scenarios both real and imagined, he shows how comets have wreaked their special havoc on Earth and other planets. Beginning with ground zero as comets take form, we track the paths their icy, rocky masses take around our universe and investigate the enormous potential that future comets have to directly affect the way we live on this planet and what we might find as we travel to other planets. In this extraordinary volume, David Levy shines his expert light on a subject that has long captivated our imaginations and fears, and demonstrates the need for our continued and rapt attention.

Join David J. Eicher in this fast-paced and entertaining journey through the history, present, and future of these important yet mysterious cosmic bodies. From ancient times, humans have been fascinated by 'broom stars' and 'blazing scimitars' lighting up the sky and moving against the fixed background of stars. The Great Comets of our time still receive in-depth attention - ISON, Hale-Bopp, Hyakutake, West, and others - while recent spacecraft encounters offer amazing insight into the earliest days of the solar system. In this guide you will discover the cutting-edge science of what comets are, how they behave, where they reside, how groups of comets are related, and much more. The author carefully explores the ideas relating comets and life on Earth - and the danger posed by impacts. He finishes with practical, how-to techniques, tips, and tricks on how to successfully observe comets and even to capture your own images of them.
