Book Description
The incomprehensible notion of a very large chunk of ice or rock from outer space smashing into the Earth has only become mainstream within the past two centuries. Though early writers imagined the utterly fantastic consequences of comet collisions and speculated on the devastation they might wreak, it was not until the 1980s when scientists finally resolved that dinosaurs were extinguished by an asteroid 66 million years ago. This startling announcement captivated the media and tilted the science fiction world but in reality, history may have been punctuated repeatedly by such events. This book collects and analyzes ideas of asteroid, comet, and planetary impacts with Earth spanning two centuries, from the first realization of extinctions in fossil records to the new millennium, reflected in scores of sci-fi stories, films, and televised science documentaries. The author examines social and geopolitical fears tied to the prospect of a cosmic-borne catastrophe. Science, fiction, and speculation are artfully melded.

Book Description
Leading specialists in various disciplines were first invited to a multidisciplinary workshop funded by ICSU on the topic to gain a better appreciation and perspective on the subject of comet/asteroid impacts as viewed by different disciplines. This volume provides a necessary link between various disciplines and comet/asteroid impacts.

Book Description
This book tells the story of the catastrophic impact of the giant 10 Km asteroid Chicxulub into the ancient Gulf of Mexico 65.5 million years ago. The book begins with a discussion of the nature of asteroids and the likelihood of future Earth-impacts. The story then turns to the discovery of a global sediment layer attributed to the fallout from the impact and a piecing together of the evidence that revealed a monster crater, buried under the Gulf. Reviewed is the myriad of geological and fossil evidence that suggested the disastrous sequence of events occurring when a "nuclear-like" explosion ripped through the sea, Earth, and atmosphere, thus forming the mega-crater and tsunami. The aftermath of the Chicxulub's event initiated decades and more of major global climate changes including a "Nuclear Winter" of freezing darkness and blistering greenhouse warming. A chapter is dedicated to the science of tsunamis and their model generation, including a portrayal of the globally rampaging Chicxulub waves. The asteroid's global devastation killed off some 70% of animal and plant life including the dinosaurs. The study of an ancient Cambrian fossil bed suggests how "roll of the dice" events can affect the future evolution of life on Earth. We see how Chicxulub's apparent destruction of the dinosaurs, followed by the their replacement with small mammals, altered forever the progress of human evolution. This book presents a fascinating glimpse through the lens of the natural sciences - the geology, climatology, and oceanography, of the effects of an enormous astronomical event.

Book Description
Presents a realistic, workable plan for defusing a potentially lethal threat from a rogue asteroid or comet. The explosion of a large meteor over Chelyabinsk, Siberia, in February 2013 is just the latest reminder that planet Earth is vulnerable to damaging and potentially catastrophic collisions with space debris of various kinds. In this informative and forward-looking book, veteran aerospace writer William E. Burrows explains what we can do in the future to avoid far more serious impacts from "Near-Earth Objects" (NEOs), as they are called in the planetary defense community. The good news is that humanity is now equipped with the advanced technology necessary to devise a long-term strategy to protect the planet. Burrows outlines the following key features of an effective planetary defense strategy- * A powerful space surveillance system capable of spotting a serious threat from space at least a year in advance * A space craft "nudge" that would throw a collision-course asteroid off target long before it poses the threat of imminent impact * A weapons system to be used as a last-ditch method to blast an NEO should all else fail. The author notes the many benefits for world stability and increasing international cooperation resulting from a united worldwide effort to protect the planet. Combining realism with an optimistic can-do attitude, Burrows shows that humanity is capable of overcoming a potentially calamitous situation.

Book Description
"Is the star from Revelation 8 already headed toward Earth? What's more, do government officials already know the answer to that question? Traditional scholarly interpretation claims that the Wormwood star will be an asteroid. Others postulate that it will poison one-third of all of Earth's waters--and we may not even notice it! Others believe the star could hit without returning, like an angel of God appearing in the sky with fire and light, bringing judgement in an instant. Do prophecies from ancient cultures and religions across the globe point to this catastrophe? Have scientists and politicians taken extreme measures to keep this under the public radar? Is this why President Donald Trump sanctioned a colossal increase to planetary defense? Follow Thomas Horn as he blazes through these questions and many others, posing answers that few in the church today are willing to provide"--Back cover.

Book Description
The United States spends approximately $4 million each year searching for near-Earth objects (NEOs). The objective is to detect those that may collide with Earth. The majority of this funding supports the operation of several observatories that scan the sky searching for NEOs. This, however, is insufficient in detecting the majority of NEOs that may present a tangible threat to humanity. A significantly smaller amount of funding supports ways to protect the Earth from such a potential collision or "mitigation." In 2005, a Congressional mandate called for NASA to detect 90 percent of NEOs with diameters of 140 meters of greater by 2020. Defending Planet Earth: Near-Earth Object Surveys and Hazard Mitigation Strategies identifies the need for detection of objects as small as 30 to 50 meters as these can be highly destructive. The book explores four main types of mitigation including civil defense, "slow push" or "pull" methods, kinetic impactors and nuclear explosions. It also asserts that responding effectively to hazards posed by NEOs requires national and international cooperation. Defending Planet Earth: Near-Earth Object Surveys and Hazard Mitigation Strategies is a useful guide for scientists, astronomers, policy makers and engineers.
