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 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 Great Comets written by Robert Burnham and published by Cambridge University Press. This book was released on 2000-05-04 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spectacular and mysterious objects that come and go in the night sky, comets have dwelt in our popular culture for untold ages. As remnants from the formation of the Solar system, they are objects of key scientific research and space missions. As one of nature's most potent and dramatic dangers, they pose a threat to our safety--and yet they were the origin of our oceans and perhaps even life itself. This beautifully illustrated book tells the story of the biggest and most awe-inspiring of all comets: those that have earned the title "Great." Robert Burnham focuses on the Great comets Hyakutake in 1996 and Hale-Bopp in 1997, which gripped attention worldwide because, for many, they were the first comets ever seen. He places these two recent comets in the context of their predecessors from past ages, among them the famous Comet Halley. Great Comets explains the exciting new discoveries that have come from these magnificent objects and profiles the spaceprobes to comets due for launch in the next few years. The book even takes a peek behind Hollywood's science-fiction fantasies to assess the real risks humanity faces from potential impacts of both comets and asteroids. For everyone interested in astronomy, this exciting book reveals the secrets of the Great Comets and provides essential tools for keeping up to date with comet discoveries in the future. Robert Burnham has been an amateur astronomer since the mid-1950s. He has been a senior editor of Astronomy magazine (1986-88) and is the author of many books and CD-ROMS, including Comet Hale-Bopp: Find and Enjoy the Great Comet and Comet Explorer.
Download or read book Journey Around the Sun written by James Gladstone and published by Owlkids. This book was released on 2021-03-15 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Halley's Comet tells its own history in this unique STEM book Halley's Comet, visible from Earth only once every 75 years, tells its own story in this unique informational picture book. With each return of the comet, the book highlights human life at that time, and how science has advanced toward a greater understanding of our universe. Told in minimal, poetic text paired with detailed captions for context, the book begins with sightings in ancient civilizations, where for centuries, the comet was a mystery recorded in art and writing. From Edmond Halley's successful prediction of the comet's return in 1758, through the advent of technologies like cameras and eventually a spacecraft that photographed its ice core, Halley's Comet tells an inspiring and wide-reaching story of scientific advancement and cultural history. The book closes by inviting readers to wonder what our world might look like the next time Halley's Comet is visible from earth, expected in 2061. What will the comet "see," next time it passes by on its journey?

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 The Comet Seekers written by Helen Sedgwick and published by HarperCollins. This book was released on 2016-10-11 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: A magical, intoxicating debut novel, both intimate and epic, that intertwines the past, present, and future of two lovers bound by the passing of great comets overhead and a coterie of remarkable ancestors. Róisín and François are immediately drawn to each other when they meet at a remote research base on the frozen ice sheets of Antarctica. At first glance, the pair could not be more different. Older by a few years, Róisín, a daughter of Ireland and a peripatetic astronomer, joins the science team to observe the fracturing of a comet overhead. François, the base’s chef, has just left his birthplace in Bayeux, France, for only the second time in his life. Yet devastating tragedy and the longing for a fresh start, which they share, as well as an indelible but unknown bond that stretches back centuries, connect them to each other. Helen Sedgwick carefully unfolds their surprisingly intertwined paths, moving forward and back through time to reveal how these lovers’ destinies have long been tied to each other by the skies—the arrival of comets great and small. In telling Róisín and François’s story, Sedgwick illuminates the lives of their ancestors, showing how strangers can be connected and ghosts can be real, and how the way we choose to see the world can be as desolate or as beautiful as the comets themselves. A mesmerizing, skillfully crafted, and emotionally perceptive novel that explores the choices we make, the connections we miss, and the ties that inextricably join our fates, The Comet Seekers reflects how the shifting cosmos unite us all through life, beyond death, and across the whole of time.

Download or read book Comets II written by M. Festou and published by University of Arizona Press. This book was released on 2004-11 with total page 780 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of comets is a field that has seen tremendous advances in recent years, far surpassing the knowledge reflected in the original Comets volume published as part of the Space Science Series in 1982. This new volume, with more than seventy contributing authors, represents the first complete overview of comet science in more than a decade and contains the most extensive collection of knowledge yet assembled in the field. Comets II situates comet science in the global context of astrophysics for the first time by beginning with a series of chapters that describe the connection between stars and planets. It continues with a presentation of the formation and evolution of planetary systems, enabling the reader to clearly see the key role played in our own solar system by the icy planetesimals that were the seeds of the giant planets and transneptunian objects. The book presents the key results obtained during the 1990s, in particular those collected during the apparition of the exceptional comets C/Hyakutake and C/Hale-Bopp in 1996-1997. The latest results obtained from the in situ exploration of comets P/Borrelly and P/Wild 2 are also discussed in detail. Each topic of is designed to be accessible to students or young researchers looking for basic, yet detailed, complete and accurate, information on comet science. With its emphasis on the origin of theories and the future of research, Comets II will enable scientists to make connections across disciplinary boundaries and will set the stage for discovery and new understanding in the coming years.
