Download or read book David Levy s Guide to Observing and Discovering Comets written by David H. Levy and published by Cambridge University Press. This book was released on 2003-05-15 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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).

Book excerpt: What are these graceful visitors to our skies? We now know that they bring both life and death and teach us about our origins. Comet begins with a breathtaking journey through space astride a comet. Pulitzer Prize-winning astronomer Carl Sagan, author of Cosmos and Contact, and writer Ann Druyan explore the origin, nature, and future of comets, and the exotic myths and portents attached to them. The authors show how comets have spurred some of the great discoveries in the history of science and raise intriguing questions about these brilliant visitors from the interstellar dark. Were the fates of the dinosaurs and the origins of humans tied to the wanderings of a comet? Are comets the building blocks from which worlds are formed? Lavishly illustrated with photographs and specially commissioned full-color paintings, Comet is an enthralling adventure, indispensable for anyone who has ever gazed up at the heavens and wondered why. Praise for Comet "Simply the best." —The Times of London "Fascinating, evocative, inspiring." —The Washington Post "Comet humanizes science. A beautiful, interesting book." —United Press International "Masterful . . . science, poetry, and imagination." —The Atlanta Journal & Constitution
Download or read book Hunting and Imaging Comets written by Martin Mobberley and published by Springer Science & Business Media. This book was released on 2010-10-08 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: For many astronomers, the holy grail of observation is to discover a comet, not least because comets always bear the name of their discoverer! Hunting and Imaging Comets was written for comet hunters and digital imagers who want to discover, rediscover, monitor, and make pictures of comets using astronomical CCD cameras and DSLRs. The old days of the purely visual comet hunter are pretty much over, but this is not to say that amateurs have lost interest in finding comets. The books also covers the discovery of comet fragments in the SOHO image data, CCD monitoring of older comets prone to violent outbursts, the imaging of new NEOs (Near Earth Objects) that have quite often been revealed as comets - not asteroids - by amateur astronomers, and the finding of recent comets impacting Jupiter.

Download or read book Visually Observing Comets written by David A. J. Seargent and published by Springer. This book was released on 2017-03-15 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: In these days of computers and CCD cameras, visual comet observers can still contribute scientifically useful data with the help of this handy reference for use in the field. Comets are one of the principal areas for productive pro-amateur collaboration in astronomy, but finding comets requires a different approach than the observing of more predictable targets. Principally directed toward amateur astronomers who prefer visual observing or who are interested in discovering a new comet or visually monitoring the behavior of known comets, it includes all the advice needed to thrive as a comet observer. After presenting a brief overview of the nature of comets and how we came to the modern understanding of comets, this book details the various types of observations that can usefully be carried out at the eyepiece of a telescope. Subjects range from how to search for new comets to visually estimating the brightness of comets and the length and orientation of tails, in addition to what to look for in comet heads and tails. Details are also given of 20 periodic comets, predicted to return between the years 2017 and 2027, that are expected to become suitable targets for visual observing, in addition to information on a famous comet potentially visible each year and subject to great outbursts of brightness.

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.
Download or read book An Introduction to Comets written by Nicolas Thomas and published by Springer Nature. This book was released on 2020-12-15 with total page 537 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written by a leading expert on comets, this textbook is divided into seven main elements with a view to allowing advanced students to appreciate the interconnections between the different elements. The author opens with a brief introductory segment on the motivation for studying comets and the overall scope of the book. The first chapter describes fundamental aspects most usually addressed by ground-based observation. The author then looks at the basic physical phenomena in four separate chapters addressing the nucleus, the emitted gas, the emitted dust, and the solar wind interaction. Each chapter introduces the basic physics and chemistry but then new specific measurements by Rosetta instruments at comet Churyumov-Gerasimenko are brought in. A concerted effort has been made to distinguish between established fact and conjecture. Deviations and inconsistencies are brought out and their significance explained. Links to previous observations of comets Tempel 1, Wild 2, Hartley 2, Halley and others are made. The author then closes with three smaller chapters on related objects, the loss of comets, and prospects for future exploration. This textbook includes over 275 graphics and figures – most of which are original. Thorough explanations and derivations are included throughout the chapters. The text is therefore designed to support MSc. students and new PhD students in the field wanting to gain a solid overview of the state-of-the-art.

Download or read book Seven Wonders of Asteroids Comets and Meteors written by Ron Miller and published by Twenty-First Century Books. This book was released on 2011-01-01 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: From earliest times, humans have wondered about the sky above them and have studied all visible objects. People began to identify differences between stars and planets, and as technology advanced with telescopes and space probes, they sought deeper understanding of the millions of bits of debris rocketing through the solar system. Scientists determined that most of these objects are left over from the creation of the planets and their moons. They classified these leftovers into categories such as asteroids, comets, and meteors. In this book, we'll explore seven wonders of asteroids, comets, and meteors. Ceres is a huge mountain-sized asteroid that orbits with other asteroids between Mars and Jupiter. Other marvels include Ganymede, the largest asteroid in the group called Earthgrazers or Near-Earth Objects, and Halley's comet, a ball of ice, that passes Earth every seventy-five or so years. We'll also explore the amazing impact that space debris can have on planets and moons. The Borealis Basin, a wondrous crater more than 5,000 miles across, formed when an asteroid collided with Mars in the ancient past. Then we will travel to the far-off Kuiper belt, where as many as 200 million icy bodies orbit, and wonder at the mystery of planetlike objects, such as Pluto and Charon. Finally, we’ll can experience a space wonder firsthand by standing outside on a night in August to watch the spectacular Perseid meteor shower fill the sky.

Download or read book Hazards Due to Comets and Asteroids written by Tom Gehrels and published by University of Arizona Press. This book was released on 1994 with total page 1340 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1993, the U.S. Department of Defense declassified information dealing with frequent explosions in the upper atmosphere caused by meteoric impact. It is estimated that impacts have occurred of a magnitude equivalent to the atomic bomb detonated at Hiroshima. Not all such space voyagers meet their end in the atmosphere, however; huge craters attest to the bombardment of earth over millions of years, and a major impact may have resulted in the extinction of dinosaurs. An impact in Siberia near the beginning of this century proves that such events are not confined to geologic time. Hazards Due to Comets and Asteroids marks a significant step in the attempt to come to grips with the threats posed by such phenomena. It brings together more than one hundred scientists from around the world, who draw on observational and theoretical research to focus on the technical problems related to all aspects of dealing with these hazards: searching for and identifying hazardous comets and asteroids; describing their statistics and characteristics; intercepting and altering the orbits of dangerous objects; and applying existent technologies—rocket boosters, rendezvous and soft-landing techniques, instrumentation—to such missions. The book considers defensive options for diverting or disrupting an approaching body, including solar sails, kinetic-energy impacts, nuclear explosives, robotic mass drivers, and various propulsion systems. A cataclysmic impact posing a threat to life on Earth is a possibility that tomorrow's technology is capable of averting. This book examines in depth the reality of the threat and proposes practical measures that can be initiated now should we ever need to deal with it.

Download or read book Observing Comets written by Nick James and published by Springer. This book was released on 2002-07-31 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since comet Shoemaker-Levy collided with the planet Jupiter with stupendous force in 1994 there has been an upsurge of amateur interest in comets. Most comets are first discovered by amateur astronomers because there are so many amateurs looking for them, and techniques and instruments have improved dramatically in the past few years. After a short but detailed introduction to the comets themselves Nick James and Gerald North describe comet hunting, photographing and imaging comets, and digital image processing. The use of computers for orbital calculations and even helping to discover new comets is given a full chapter, as are advanced techniques including comet photometry and spectroscopy. This comprehensive book has an accompanying CD-ROM and is at once a "primer" for comet hunters and a reference text for more advanced amateur astronomers.
