The brilliant trailing beauty of fiery comets has inspired fear, wonder, and awe since the dawn of human history. Brighter than stars, moving and disappearing in their own singular orbits, comets have been among the most mysterious elements in the sky, eluding our understanding until very recently. With the aid of space probes, scientists have discovered that these swiftly moving chunks of ice and carbon are more plentiful and far more dangerous than suspected. Scientists are also beginning to realize the monumental role played by comets in the development of the Earth and solar system. David Levy describes in dramatic detail the thrilling yet often devastating effects of comet collisions. In the dawn of our solar system, the Earth was barraged with comets that may have carried the materials necessary to lay the foundations for life on this planet. Levy also presents compelling evidence for later comet collisions, including those of the age of dinosaurs. Great impacts, Levy asserts, not only caused the extinction of the dinesaurs, but ushered in new species of life. As Levy so clearly explains, scientists are realizing that comet collisions are virtually inevitable. Levy reveals possible future collisions with the Earth and describes the terrible risks to life they would pose. He even shows how we might prepare to withstand the impact of large comets in the future.

Veteran comet hunter and eloquent popular astronomy writer David H. Levy takes amateur sky-watchers on a fascinating journey into deep space in this enthusiastic and informative survey of the many far distant yet observable objects in the night sky. Light years beyond our solar system, deep sky objects include such intriguing phenomena as double and triple stars, nebulae, galaxies, and quasars. Designed to be accessible for even beginners, Levy''s clear, elegant descriptions will guide astronomy buffs in any hemisphere and locale (light-polluted cities as well as dark countryside) to the wonders of our enormous universe. As the discoverer or codiscoverer of twenty-one comets, including the famous Shoemaker-Levy 9 that crashed into Jupiter in 1994, Levy has devoted many decades of experience to observing the night sky. Over the years he has located over 300 deep sky objects, of which more than 100 "best and brightest" are featured in this book. Levy offers a physical description and a discussion of each object''s history and beauty, as well as a star atlas to aid in finding the objects. Proceeding from objects closest to our solar system to those farthest away, Levy gives readers an awe-inspiring glimpse into the structure of the cosmos. Complete with both color and black-and-white photos, plus many helpful illustrations, Deep Sky Objects is the ideal guide to the wonders of the universe for both experienced and novice star gazers.

In the 1950s, Immanuel Velikovsky propounded catastrophism in several popular books including the bestselling Worlds in Collision. He speculated that the ‘planet’ Venus was in fact a former comet which had been ejected from Jupiter. Subsequently, 3,500 years ago, it made two catastrophically close passes by Earth 52 years apart. It later interacted with Mars, which had a series of near collisions with Earth ending in 687 BCE, before finally settling into its current orbit.Was Velikovsky correct, did Venus appear as a gigantic comet in ancient times? Comet Venus is the second book in the God King Scenario Series. The first book, An Ancient World in Chaos, presented a fascinating model whereby Mars, Venus, Mercury and the Moon played havoc with Earth for an incredible 3,000 years, coming so close they loomed larger than the Sun. In support of such incredible claims, Gilligan calls upon the most fascinating civilisation of ancient times – the Ancient Egyptians. He proposes that the divine god-kings of Pharaonic Egypt were first and foremost guises of planetary bodies as they appeared to move back and forth to Earth. He further proposes that these heavenly monarchs were represented by human ‘doubles’ – mortal Pharaohs who were believed to be earthly manifestations of god-king planets.The primary objective of Comet Venus is to vindicate Velikovsky and conclusively demonstrate that the comet images on the front and back covers of this book have nothing whatsoever to do with the Sun! They are exact physical representations of the planet Venus as it took on the attributes of a comet in the skies above Earth only a few thousand years ago.

From the visionary author of The Genesis Quest, a “wildly imaginative” (Greg Bear) science fiction novel about a young man’s struggle for survival on a comet made of ice. In Donald Moffitt’s brilliant cosmic adventure, Torris, son of the Facemaker, knows only his small community at the base of the great Tree on a comet with almost no gravity or atmosphere. Torris’s daily struggle for survival includes harvesting frozen air to keep breathing, dodging flutterbeasts, and hunting meatbeasts for food. When the time comes to make his vision quest to the top of the Tree, Torris is completely unprepared for what he finds: a thieving and hostile fellow quester; Ning, a female hunter in search of food to save her family on a neighboring comet; and humans from a massive starship that has spent billions of years crossing the galaxy from Earth’s solar system. Perfect for fans of Arthur C. Clarke, Larry Niven, and Peter F. Hamilton, Children of the Comet is an enthralling space odyssey about a young man grappling with unexpected cultural differences and learning to adapt in the face of an uncertain and rapidly changing fantastical future.

Naked-eye comets are far from uncommon. As a rough average, one appears every 18 months or thereabouts, and it is not very unusual to see more than two in a single year. The record so far seems to have been 2004, with a total of five comets visible without optical aid. But 2006, 1970, and 1911 were not far behind with a total of four apiece. Yet, the majority of these pass unnoticed by the general public. Most simply look like fuzzy stars with tails that are either faint or below the naked-eye threshold. The ‘classical’ comet – a bright star-like object with a long flowing tail – is a sight that graces our skies about once per decade, on average. These ‘great comets’ are surely among the most beautiful objects that we can see in the heavens, and it is no wonder that they created such fear in earlier times. Just what makes a comet ‘‘great’’ is not easy to define. It is neither just about brightness nor only a matter of size. Some comets can sport prodigiously long tails and yet not be regarded as great. Others can become very bright, but hardly anyone other than a handful of enthusiastic astronomers will ever see them. Much depends on their separation from the Sun, the intensity of the tail, and so forth.

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).
