Download or read book Cosmic Impact written by Andrew May and published by Icon Books. This book was released on 2019-02-07 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: As end-of-the-world scenarios go, an apocalyptic collision with an asteroid or comet is the new kid on the block, gaining respectability only in the last decade of the 20th century with the realisation that the dinosaurs had been wiped out by just such an impact. Now the science community is making up for lost time, with worldwide efforts to track the thousands of potentially hazardous near-Earth objects, and plans for high-tech hardware that could deflect an incoming object from a collision course – a procedure depicted, with little regard for scientific accuracy, in several Hollywood movies. Astrophysicist and science writer Andrew May disentangles fact from fiction in this fast-moving and entertaining account, covering the nature and history of comets and asteroids, the reason why some orbits are more hazardous than others, the devastating local and global effects that an impact event would produce, and – more optimistically – the way future space missions could avert a catastrophe.
Book Synopsis Cosmic Implications of Ponderomotive Wave Forces by : Rickard Lundin
Download or read book Cosmic Implications of Ponderomotive Wave Forces written by Rickard Lundin and published by Cambridge Scholars Publishing. This book was released on 2022-09-27 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores the ponderomotive wave forces of space plasma, which have implications for a large number of cosmic plasma phenomena. Plasma is a state of matter comprising an equal amount of negative (electrons) and positive (ions) charged particles. The ionized state is the dominating state of matter in the cosmos for stars, galaxies and their corresponding intermediate regions. This book discusses the plasma state and its corresponding theoretical implications based on the analysis of space plasma data. The theory of ponderomotive forcing offers a most important tool for the analysis of “in situ” plasma data of acceleration processes in the terrestrial and Martian plasma environment. In addition, the solar wind interaction with objects in the solar system also provides a roadmap for the analysis and interpretations of other stellar and galactic objects, out of reach for direct “in-situ” measurements.
Book Synopsis Assessment and Mitigation of Asteroid Impact Hazards by : Josep M. Trigo-Rodríguez
Download or read book Assessment and Mitigation of Asteroid Impact Hazards written by Josep M. Trigo-Rodríguez and published by Springer. This book was released on 2016-12-19 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is a compilation of the research presented at the International Asteroid Day workshop which was celebrated at Barcelona on June 30th, 2015. The proceedings discuss the beginning of a new era in the study and exploration of the solar system’s minor bodies. International Asteroid Day commemorates the Tunguska event of June 30th, 1908. The workshop’s goal was to promote the importance of dealing proactively with impact hazards from space. Multidisciplinary experts contributed to this discussion by describing the nature of comets and asteroids along with their offspring, meteoroids. New missions to return material samples of asteroids back to Earth such as Osiris-REx and Hayabusa 2, as well as projects like AIM and DART which will test impact deflection techniques for Potentially Hazardous Asteroids encounters were also covered. The proceedings include both an outreach level to popularize impact hazards and a scientific character which covers the latest knowledge on these topics, as well as offering proposals of promising new techniques that will help gain new insights of the properties of these challenging bodies by studying meteoroids and meteorites. Asteroids, comets, meteoroids and meteorites are introduced with descriptions of their nature, origin, and solar system pathways.

Download or read book Cosmic Collisions written by Dana Desonie and published by Holt Paperbacks. This book was released on 2014-01-14 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cosmic collisions have forever shaped the planets in our solar system, sculpting Earth and our Moon. They are still happening right in our neighborhood, as we saw in July 1994 when comet fragments bombarded the surface of Jupiter. What if a collision of that magnitude were to occur on Earth? Would the effect be anywhere near that of the collision that wiped out the dinosaurs 65 million years ago? Scientists have just begun to track distant asteroids and comets that may pose a threat to Earth in years to come. In Scientific American Focus: Cosmic Collisions Dana Desonie traces the history of cosmic collisions and proposes various solutions to what many view as our impending doom, answering these questions and more: -How often does Earth experience a cosmic collision? -Did a massive collision kill off the dinosaurs? -How do scientists track and predict collisions? -What did we learn from the Jupiter collision of 1994? -How real is the threat of a collision in our future? -How can we defend our planet?
Book Synopsis Current Topics in Astrofundamental Physics: The Cosmic Microwave Background by : Norma G. Sànchez

Book Synopsis The Cosmic Connection by : Jeff Kanipe
Download or read book The Cosmic Connection written by Jeff Kanipe and published by Prometheus Books. This book was released on 2011-01-27 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this sweeping tour of the cosmos and our place within it, acclaimed science writer Jeff Kanipe shows the many ways we are connected to the vast universe we inhabit. Long before our apelike ancestors dropped from the trees and began playing with fire, even before the Sun emerged from its chrysalis of dust and irradiated its brood of planets, numberless and nameless astronomical events affected Earth and its emerging life-forms. Our chemical makeup--from the iron in our blood to the calcium in our bones--derives from stars that lived and died hundreds of millions of years ago. Comets have showered organic molecules into our oceans, and asteroid impacts have wiped out predominant species that lived before. Tracing the whole natural history of how events in the near and far universe have influenced life on Earth today, and how they might influence life in the future, Kanipe, with unparalleled eloquence, explores a host of intriguing questions: - How the Earth's orbit and inclination have triggered past ice ages - The role ancient supernovae may have played in mass extinctions and genetic changes - How a slight but persistent dip in solar output contributed to a multicentury cooling event called the "Little Ice Age" - How ancient asteroid impacts pressed Earth's evolutionary reset button and how astronomers are striving to make sure that it won't happen again - The widespread effects that our Sun's changing galactic environment has on life and climate Kanipe also reflects upon the possible societal effects of alien contact, a type of cosmic intervention that some astronomers believe could happen within the next few decades. His elegant, jargon-free descriptions of the truly "big-picture view" of life on Earth will fascinate and inform everyone who has an interest in astronomy, the evolution of our planet, and the future of humankind.
Book Synopsis Habitability and Cosmic Catastrophes by : Arnold Hanslmeier
Download or read book Habitability and Cosmic Catastrophes written by Arnold Hanslmeier and published by Springer Science & Business Media. This book was released on 2008-11-14 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: The search for life in the universe is one of the most challenging topics of science. It is not a modern topic at all, since more than 100 years ago, it was speculated that on the Moon, there are oceans and seas; on Venus, there are swamps and also Mars is inhabitated. However, now we have the scienti?c background and the scienti?c tools to answer this question and it is also certain that the answer would have deep imp- cations for our culture, philosophy, and religions. If we ?nd that life has developed on other planets or satellites of giant planets, then this would be the ?nal breakdown of our central position in the universe. But is life a widespread phenomenon? How vulnerable is it to changing conditions and even catastrophic events? These topics will be discussed in this book. If life is in the extreme case a unique phenomenon found only on planet Earth, which seems to be highly unrealistic, then also it is important to discuss how it is adaptable to changing external conditions. Can we survive a cosmic catastrophe? How do these catastrophes change habitability? Which forms of life are more v- nerable? It was mentioned that now science has made great progress to answer such qu- tions. Let us give some examples. In modern biology, in connection with organic chemistry, the origin of life is studied.
Book Synopsis Evaluating the Biological Potential in Samples Returned from Planetary Satellites and Small Solar System Bodies by : National Research Council
Download or read book Evaluating the Biological Potential in Samples Returned from Planetary Satellites and Small Solar System Bodies written by National Research Council and published by National Academies Press. This book was released on 1998-10-14 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the first time since the Apollo program, NASA and space agencies abroad have plans to bring samples to Earth from elsewhere in the solar system. There are missions in various stages of definition to gather material over the next decade from Mars, an asteroid, comets, the satellites of Jupiter, and the interplanetary dust. Some of these targets, most especially Jupiter's satellites Europa and Ganymede, now appear to have the potential for harboring living organisms. This book considers the possibility that life may have originated or existed on a body from which a sample might be taken and the possibility that life still exists on the body either in active form or in a form that could be reactivated. It also addresses the potential hazard to terrestrial ecosystems from extraterrestrial life if it exists in a returned sample. Released at the time of the Internationl Committee on Space Research General Assembly, the book has already established the basis for plans for small body sample retruns in the international space research community.

Download or read book Impact! written by Gerrit L. Verschuur and published by Oxford University Press. This book was released on 1997-12-18 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most scientists now agree that some sixty-five million years ago, an immense comet slammed into the Yucatan, detonating a blast twenty million times more powerful than the largest hydrogen bomb, punching a hole ten miles deep in the earth. Trillions of tons of rock were vaporized and launched into the atmosphere. For a thousand miles in all directions, vegetation burst into flames. There were tremendous blast waves, searing winds, showers of molten matter from the sky, earthquakes, and a terrible darkness that cut out sunlight for a year, enveloping the planet in freezing cold. Thousands of species of plants and animals were obliterated, including the dinosaurs, some of which may have become extinct in a matter of hours. In Impact, Gerrit L. Verschuur offers an eye-opening look at such catastrophic collisions with our planet. Perhaps more important, he paints an unsettling portrait of the possibility of new collisions with earth, exploring potential threats to our planet and describing what scientists are doing right now to prepare for this awful possibility. Every day something from space hits our planet, Verschuur reveals. In fact, about 10,000 tons of space debris fall to earth every year, mostly in meteoric form. The author recounts spectacular recent sightings, such as over Allende, Mexico, in 1969, when a fireball showered the region with four tons of fragments, and the twenty-six pound meteor that went through the trunk of a red Chevy Malibu in Peekskill, New York, in 1992 (the meteor was subsequently sold for $69,000 and the car itself fetched $10,000). But meteors are not the greatest threat to life on earth, the author points out. The major threats are asteroids and comets. The reader discovers that astronomers have located some 350 NEAs ("Near Earth Asteroids"), objects whose orbits cross the orbit of the earth, the largest of which are 1627 Ivar (6 kilometers wide) and 1580 Betula (8 kilometers). Indeed, we learn that in 1989, a bus-sized asteroid called Asclepius missed our planet by 650,000 kilometers (a mere six hours), and that in 1994 a sixty-foot object passed within 180,000 kilometers, half the distance to the moon. Comets, of course, are even more deadly. Verschuur provides a gripping description of the small comet that exploded in the atmosphere above the Tunguska River valley in Siberia, in 1908, in a blinding flash visible for several thousand miles (every tree within sixty miles of ground zero was flattened). He discusses Comet Swift-Tuttle--"the most dangerous object in the solar system"--a comet far larger than the one that killed off the dinosaurs, due to pass through earth's orbit in the year 2126. And he recounts the collision of Comet Shoemaker-Levy 9 with Jupiter in 1994, as some twenty cometary fragments struck the giant planet over the course of several days, casting titanic plumes out into space (when Fragment G hit, it outshone the planet on the infrared band, and left a dark area at the impact site larger than the Great Red Spot). In addition, the author describes the efforts of Spacewatch and other groups to locate NEAs, and evaluates the idea that comet and asteroid impacts have been an underrated factor in the evolution of life on earth. Astronomer Herbert Howe observed in 1897: "While there are not definite data to reason from, it is believed that an encounter with the nucleus of one of the largest comets is not to be desired." As Verschuur shows in Impact, we now have substantial data with which to support Howe's tongue-in-cheek remark. Whether discussing monumental tsunamis or the innumerable comets in the Solar System, this book will enthrall anyone curious about outer space, remarkable natural phenomenon, or the future of the planet earth.

Download or read book Cosmic Society written by Peter Dickens and published by Routledge. This book was released on 2007-11-08 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: Space weaponry, satellite surveillance and communications, and private space travel are all means in which outer space is being humanized: incorporated into society’s projects. But what are the political implications of society not only being globalized, but becoming ‘cosmic’? Our ideas about society have long affected, and been affected by, our understanding of the universe: large sections of our economy and society are now organized around humanity’s use of outer space. Our view of the universe, our increasingly ‘cosmic’ society, and even human consciousness are being transformed by new relations with the cosmos. As the first sociological book to tackle humanity’s relationship with the universe, this fascinating volume links social theory to classical and contemporary science, and proposes a new ‘cosmic’ social theory. Written in a punchy, student-friendly style, this timely book engages with a range of topical issues, including cyberspace, terrorism, tourism, surveillance and globalization.
Book Synopsis Vindication of Cosmic Biology by : Nalin Chandra Wickramasinghe
Download or read book Vindication of Cosmic Biology written by Nalin Chandra Wickramasinghe and published by World Scientific. This book was released on 2015-05-28 with total page 712 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the year 2015, 100 years after Fred Hoyle was born, the ideas relating to the cosmic origins of life are slowly gaining credence in scientific circles. Once regarded as outrageous heresy, evidence from a variety of disciplines — astronomy, geology, biology — is converging to support these once heretical ideas. This volume opens with recent review articles pointing incontrovertibly towards our cosmic heritage, followed by a collection of published articles tracing the development of the theory throughout the years. The discovery that microorganisms — bacteria and viruses — are incredibly resistant to the harshest conditions of space, along with the detection of an estimated 144 billion habitable planets around other star systems in our galaxy alone, makes it virtually impossible to maintain that life on one planet will not interact with life elsewhere. The emerging position is that life arose exceedingly rarely, possibly only once, in the history of the cosmos, but its subsequent spread was unstoppable. "Panspermiology" can no longer be described as an eccentric doctrine, but rather is the only doctrine supported by an overwhelming body of evidence. Fred Hoyle's work in this area may in the fullness of time come to be regarded as his most important scientific contribution.
