Comets, Meteors & Asteroids in The Books Store

Miner and Wessen have teamed together again, along with noted planetary ring scientist, Dr Jeffrey Cuzzi, to produce the most comprehensive and up-to date book on the topic of planetary rings systems yet written. The book is written in a style and at a language level easily accessible to the interested non-expert. The authors cover the scientific significance of ring studies, the history of their discovery and characterization, the observations of Pioneer 10 at Jupiter, Pioneer 11 and Voyager 1 at Jupiter and Saturn, Voyager 2 at all four giant planets of the solar system, and Galileo at Jupiter. The discussion also includes subsequent scientific analyses of the observations, along with the accompanying theoretical studies, including various theories for the origins of planetary ring systems. Finally, the four ring systems are both compared and contrasted in a chapter on comparative planetology.

Early additional findings from the Cassini spacecraft in orbit around Saturn (due to arrive in July 2004) will also be included. The first series of ring orbits by Cassini occur between May and October 2005 and this book will provide the first summary of these detailed observations, the first since the flyby of Voyager 2 in 1981. Images of Saturn, as the Cassini spacecraft approached the planet in spring 2004, revealed a wealth of detail in the ring system, a foretaste of the excitement to come.

Each chapter includes extensive notes, references, figures and tables. A bibliography is also included at the end of each chapter, for those who want to peruse the existing literature. Both a glossary and a topical index will make the book a useful reference tool for planetary scientists as well as for the targeted audience of non-experts.

Is mankind a central product of the universe? Or merely an accident fit to survive? The exploding discoveries of biology in the past half century could radically change the scientific answer to this debate.

In Nature's Destiny, Michael Denton marshals a stunning range of biological, chemical, and physical evidence to answer systematically a simple question: Could life elsewhere in the universe be significantly different from life on Earth? Must it rely on carbon, water, DNA, amino acids, and proteins? Could there be an alternative to DNA, or could DNA be constructed out of different components? Could cells be designed differently? From these building blocks he dares to ask the boldest of questions: Is it possible there are life forms radically different from those realized during the course of evolution on Earth? And even: Is a Homo sapiens -- like creature the only possible highly intelligent species, given the laws of biology that exist throughout the universe?

The stunning answer to his last question is yes. Life is highly constrained by the laws of nature. If, for example, the ratio between strong and weak chemical bonds had not been precisely what it is, if the thermal properties of water were not precisely what they are, if the atmosphere of the Earth had not had just the right properties to filter out harmful radiation, then a flourishing biosphere such as exists on Earth would be impossible. For life to develop beyond the most primitive stage hinted at by the famous Mars fossils requires an earthlike planet, with earthlike atmosphere and oceans.

The Greatest Comets of History is unique. There are a few books on comets that make passing reference to some of the famous and spectacular objects of earlier years, and a few descriptive catalogues are available, but little detailed descriptive information is contained in either of these sources. This book fills the vacant niche that exists between general books, academic (and often cryptic) catalogues, and huge detailed catalogues such as Kronk’s Cometography. The Greatest Comets of History is a detailed descriptive account – in non-technical language – of what are deemed to have been the most spectacular and notable comets ever recorded, beginning with ‘Aristotle’s Comet’ of 372 BC and ending with McNaught’s Comet of 2007. Halley’s Comet is given a separate chapter and there is an introductory chapter on comets in general, explaining in lay terms what they are and correcting a few popular misconceptions. This is not only a fascinating read for astronomers at every level, but in pulling together a vast amount of information previously available only in disparate academic sources it is a major contribution to the literature.

In this engaging volume, Curtis Peebles surveys the science of asteroids, offering a highly readable account of the many ways in which they form out of the flotsam and jetsam of larger celestial bodies, the dust and debris of space. He adds to this scientific overview an anecdotal history of asteroid discovery and detection, which, he writes, was often the work of gifted astronomers working with less than ideal equipment, and all too often dismissed by their professional counterparts. Peebles discusses in detail the rules by which asteroids are catalogued and named--some, for instance, bear the monikers of eminent scientists, others of their patrons, and still others of more unlikely honorees, such as the group of asteroids named for the various Beatles. He also touches on efforts to protect Earth from asteroid impacts--the father of that planetary defense being none other than the poet Lord Byron--which he calls "the only natural disaster that human society can prevent."
