Book excerpt: 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.

Book excerpt: How did a company best known for its glass jars hit a comet 83 million miles away? The answer involves technical expertise, heroic dedication, an industrial giant’s push to modernize, Hitler’s V-2 rocket, speakers destined for a Hall & Oates summer concert tour, and the search for life’s origins. In “From Jars to the Stars: How Ball Came to Build a Comet-Hunting Machine,” award-winning science journalist Todd Neff presents an inside look at the backgrounds and motivations of the men and women who actually create the spacecraft on which the American space program rides. A timeless story of science, engineering, politics and business strategy intertwining to bring success in the brutal business of space, “From Jars to the Stars” is a lively account of one of mankind’s great modern achievements. It is a story about people, foremost those on the Deep Impact mission, which smashed a spacecraft into the comet Tempel 1. “From Jars to the Stars” explores the improbable beginnings of Ball Aerospace & Technologies Corp., which built the comet hunter, and the evolution of the American space agency that funded it. The book begins with the story of a group of University of Colorado students who built a “sun seeker” for the noses of sounding rockets studying the home star. The pathbreaking device sparked the creation and development of both Ball Aerospace and the University of Colorado’s formidable Laboratory for Atmospheric and Space Physics. “From Jars to the Stars” describes how Ed Ball, president of the Ball Brothers Company of Muncie, Indiana, ended up owning a space business in Boulder, Colorado, through a combination of strategic intent and serendipity. Neff explores the personalities and the technologies behind Ball’s pioneering spacecraft, the Orbiting Solar Observatory launched in 1962. The Ball orbiter prepares the ground for Deep Impact, showing readers how much—and how little—changed across four decades of American space exploration. Neff goes on to show how Ball Aerospace evolved into an organization capable of building seven Hubble Space Telescope instruments as well as the comet hunter at the center of the story. The author describes the development of the American space enterprise as it went from emphasizing big-budget “gigabuck” missions to “faster, better, cheaper” spacecraft of the sort Ball specialized in. Neff pays special mind to NASA’s Jet Propulsion Laboratory, the world leader in interplanetary space exploration and Ball’s partner on Deep Impact. It was often a rocky marriage. Throughout, Neff makes clear that robotic space missions are indeed manned: the people just happen to stay on the ground.

Download or read book The Heart Of A Comet written by Pages Matam and published by SCB Distributors. This book was released on 2014-09-15 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Heart of a Comet is a collection of poems and short stories offering the tale of Comet, who fell from the sky unto an unfamiliar plane of existence. On his quest to return home, he has many life-altering encounters with people and places that completely change his perspective of what it means to love and to live. Through this series of truths, the lines between dreams and reality so often blur, this creates a new mosaic to an ultimate revelation: the internal lesson of the true meaning of purpose. What are we here for? Why do we experience the things that we do, and why do we react to them in the ways that we do? All questions posed with seemingly infinite answers. In this conceptual miscellany, author Pages Matam touches on topics of immigrant experience to fatherhood and love in all of its beautiful but also often tragic and traumatic faces. As the tale unfolds, we become swallowed by a self reflective journey with a destination that could only be sought from one's own soul searching heart...the Heart of a Comet.

Book excerpt: This book is for the reader who takes interest in an age-old issue that remains contemporary with every succeeding generation. When, how, and why we are here are questions that have caused countless generations of thinkers and laymen alike to intuitively seek at the very least the semblance of an answer to questions that have become more of an outlook than a science, and in turn spring up among the problems of modern life as opposed to allowing for a resolution to that which was intended to clarify instead of further complicate. Free from the shackles and bias imposed by the various schools of religious, scientific and philosophical thought, the examinations offered herein are rooted in systematic analyses of the scientific, philosophical, ethical, social and finally the religious; which in turn allows for the explanation and justification of concepts that enable the reader to adopt a perspective relevant to the distinctions of absolute truth and relativistic assumptions. Our age is accurately referred to as the age of advancement and technology and for good reason. The rapid pace of progression over the last century in the life sciences has contributed to a broadened understanding of knowledge itself and its relation to the psychological and sociological aspects of our existence. As a result of the significant expansion of the sciences, the desire for an understanding of “self” and simply of “why” has in many ways been diluted, thus negating the never ending questions that once tugged at man's conscious in the middle of the night for thousands of years. Today's amazing achievements have laid the foundation for a whole series of newer problems and questions that threaten mankind as never before. The medical and biological sciences have enabled us to have a life expectancy beyond that of prior generations, however coupled with that are the problems of population explosion, which in the not too distant future will give rise to serious concerns. We have the ability to harness the power of the atom, yet along with it comes the ability to destroy all that we hold sacred. Taking into consideration the advanced age we live in, how does one account for the remarkable complexity extant throughout the known universe? Is one to assume that our consciousness coupled with our overwhelming sense of purpose can be attributed solely to “random chance” alone? The law of causation deals with the need for a preceding event leading to the outcome, and despite the fact that this scientific age has left its handprint on every facet of life today, it has failed to satisfy the innate question of simply,.............................................. why?
Download or read book The Greatest Comets in History written by David A.J. Seargent and published by Springer Science & Business Media. This book was released on 2008-12-16 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

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 Children of the Comet written by Donald Moffitt and published by Open Road Media. This book was released on 2015-10-13 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

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 Comets written by Julio A. Fernandez and published by Springer Science & Business Media. This book was released on 2005-11-13 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: Comets are small bodies, but of great cosmic relevance. Given its pristine nature, they may preserve valuable and unique information on thechemical and physical processes that took place in theearly solar system, and that may be occurring in the formation of other planetary systems. They might have even played a very important role in the origin of life on Earth. Beyond that, since ancient times comets have inspired awe, superstition, and also curiosity anddebate. Their sudden apparitions challenged the long-held view of the immutability of the heavens, which triggered a long debate on whether comets had a heavenly or terrestrial nature. Therefore, comets have a prominent role in the history of scienti?cthought, that goes back to the most ancient civilizations. The last apparition of comet Halley in 1986 was a landmark since it arouse a great expectation in the scienti?c community and in the public at large. For the ?rst time, a ?otilla of spacecrafts visited a comet. Agreat number of popular and technical books were written on Halley, and comets in general, around the mid-eighties. The interest in comets never subsided after Halley’s passage which is re?ected in the large volume of printed material on these bodies. I have taken the challenge to write a new book on comets that summarizes most of the recent advances on thesubject, including my own workdeveloped during the last 25 years.

Download or read book Ultraviolet Astronomy and the Quest for the Origin of Life written by Ana I. Gomez de Castro and published by Elsevier. This book was released on 2021-03-27 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultraviolet Astronomy and the Quest for the Origin of Life addresses the use of astronomical observations in the ultraviolet range to better understand the generation of complex, life-precursor molecules. The origin of RNA is still under debate but seems to be related to the generation of pools of complex organic molecules submitted to heavy cycles of solution in water and drying. This book investigates whether these cycles require a planetary surface or may occur in space by examining both the theoretical and observational aspects of the role of UV radiation in the origin of life. This book offers the latest advances in these studies for astronomers, astrobiologists and planetary scientists. Addresses both the theoretical and observational aspects of the role of Ultraviolet (UV) radiation in the origin of life Builds on the requirements to produce prebiotic molecules in space and the implications for the origin of RNA Investigates the use of ultraviolet observations related to planetary system formation, the evolution of young planetary disks, and the interaction of stars with planetary atmospheres
Download or read book Chronicling the Golden Age of Astronomy written by Neil English and published by Springer. This book was released on 2018-10-31 with total page 665 pages. Available in PDF, EPUB and Kindle. Book excerpt: The invention of the telescope at the dawning of the 17th century has revolutionized humanity's understanding of the Universe and our place within it. This book traces the development of the telescope over four centuries, as well as the many personalities who used it to uncover brand-new revelations about the Sun, Moon, planets, stars and distant galaxies. Starting with early observers such as Thomas Harriot, Galileo, Johannes Hevelius, Giovanni Domenico Cassini, Robert Hooke and Christian Huygens, the book explores how these early observers arrived at essentially correct ideas concerning the objects they studied. Moving into the 18th and 19th centuries, the author describes the increasing sophistication of telescopes both large and small, and the celebrated figures who used them so productively, including the Herschels, Charles Messier, William Lassell and the Earls of Rosse. Many great discoveries were also made with smaller instruments when placed in the capable hands of the Struve dynasty, F.W. Bessel, Angelo Secchi and S.W Burnham, to name but a few. Nor were all great observers of professional ilk. The book explores the contributions made by the 'clerical astronomers,' William Rutter Dawes, Thomas William Webb, T.E.R Philips and T.H.E.C Espin, as well as the lonely vigils of E.E. Barnard, William F. Denning and Charles Grover. And in the 20th century, the work of Percival Lowell, Leslie Peltier, Eugene M. Antoniadi, Clyde Tombaugh, Walter Scott Houston, David H. Levy and Sir Patrick Moore is fully explored. Generously illustrated throughout, this treasure trove of astronomical history shows how each observer's work led to seminal developments in science, and providing key insights into how we go about exploring the heavens today.
