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).
Download or read book David Levy s Guide to Observing Meteor Showers written by David H. Levy and published by Cambridge University Press. This book was released on 2008 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Asteroids and Dwarf Planets and How to Observe Them written by Roger Dymock and published by Springer Science & Business Media. This book was released on 2010-11-01 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dwarf planets (which were formerly called asteroids except for the planet Pluto), and the smaller Solar System bodies still called asteroids today, are making front page news, particularly those that are newly discovered and those that might present a hazard to life on Earth by impacting our planet. In this age of giant telescopes and space probes, these small Solar System bodies have advanced from being tiny points of light to bodies worthy of widespread study. This book describes the dwarf planets and asteroids themselves, their origins, orbits, and composition, and at how amateur astronomers can play a part in their detection, tracking, and imaging. The book is divided into two parts. Part I describes physical properties (including taxonomic types) of dwarf planets and asteroids, how they formed in the early life of the Solar System, and how they evolved to their present positions, groups, and families. It also covers the properties used to define these small Solar System bodies: magnitude, rotation rates (described by their light-curves), and orbital characteristics. Part II opens with a description of the hardware and software an amateur or practical astronomer needs to observe and also to image asteroids. Then numerous observing techniques are covered in depth. Finally, there are lists of relevant amateur and professional organizations and how to submit your own observations to them.
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.
Download or read book COMETS written by David J. Eicher and published by Cambridge University Press. This book was released on 2013-09-23 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Shoemaker by Levy written by David H. Levy and published by Princeton University Press. This book was released on 2021-02-09 with total page 319 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Cometography Volume 6 1983 1993 written by Gary W. Kronk and published by Cambridge University Press. This book was released on 2017-04-20 with total page 1116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cometography is a multi-volume catalog of every comet observed from ancient times up to the 1990s, when the internet took off as a medium of scientific record. It uses the most reliable orbits known to determine the distances from the Earth and Sun at the time of discovery and last observation, as well as the largest and smallest angular distance to the Sun, most northerly and southerly declination, closest distance to the Earth, and other details, to enable the reader to understand each comet's physical appearance. Volume 6, the final volume in the catalog, covers the observations and pertinent calculations for every comet seen between 1983 and 1993. The comets are listed in chronological order, with complete references to publications relating to each comet and physical descriptions of each comet's development throughout its apparition. Cometography is the definitive reference on comets through the ages, for astronomers and historians of science.

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.
