Book Description
An insider's look at the science of near-Earth comets and asteroids Of all the natural disasters that could befall us, only an Earth impact by a large comet or asteroid has the potential to end civilization in a single blow. Yet these near-Earth objects also offer tantalizing clues to our solar system's origins, and someday could even serve as stepping-stones for space exploration. In this book, Donald Yeomans introduces readers to the science of near-Earth objects—its history, applications, and ongoing quest to find near-Earth objects before they find us. In its course around the sun, the Earth passes through a veritable shooting gallery of millions of nearby comets and asteroids. One such asteroid is thought to have plunged into our planet sixty-five million years ago, triggering a global catastrophe that killed off the dinosaurs. Yeomans provides an up-to-date and accessible guide for understanding the threats posed by near-Earth objects, and also explains how early collisions with them delivered the ingredients that made life on Earth possible. He shows how later impacts spurred evolution, allowing only the most adaptable species to thrive—in fact, we humans may owe our very existence to objects that struck our planet. Yeomans takes readers behind the scenes of today’s efforts to find, track, and study near-Earth objects. He shows how the same comets and asteroids most likely to collide with us could also be mined for precious natural resources like water and oxygen, and used as watering holes and fueling stations for expeditions to Mars and the outermost reaches of our solar system.

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.

Book Description
Early Earth Systems provides a complete history of the Earth from its beginnings to the end of the Archaean. This journey through the Earth's early history begins with the Earth's origin, then examines the evolution of the mantle, the origin of the continental crust, the origin and evolution of the Earth's atmosphere and oceans, and ends with the origin of life. Looks at the evidence for the Earth's very early differentiation into core, mantle, crust, atmosphere and oceans and how this differentiation saw extreme interactions within the Earth system. Discusses Archaean Earth processes within the framework of the Earth System Science paradigm, providing a qualitative assessment of the principal reservoirs and fluxes in the early Earth. “The book would be perfect for a graduate-level or upper level undergraduate course on the early Earth. It will also serve as a great starting point for researchers in solid-Earth geochemistry who want to know more about the Earth’s early atmosphere and biosphere, and vice versa for low temperature geochemists who want to get a modern overview of the Earth’s interior.” Geological Magazine, 2008

Book Description
Earth is the latest science fiction novel from multiple Hugo Award winner Ben Bova, author of Apes and Angels and Survival A wave of lethal gamma radiation is expanding from the core of the Milky Way galaxy at the speed of light, killing everything in its path. The countdown to when the death wave will reach Earth and the rest of the solar system is at two thousand years. Humans were helped by the Predecessors, who provided shielding generators that can protect the solar system. In return, the Predecessors asked humankind's help to save other intelligent species that are in danger of being annihilated. But what of Earth? With the Death Wave no longer a threat to humanity, humans have spread out and colonized all the worlds of the solar system. The technology of the Predecessors has made Earth a paradise, at least on the surface. But a policy of exiling discontented young people to the outer planets and asteroid mines has led to a deep divide between the new worlds and the homeworld, and those tensions are about to explode into open war.

Book Description
Just how near is the end of the world? Behind the veil of safety of everyday life in the West lurks the sinister reality of a chaotic universe. Doomsday reveals the very real threats posed to modern civilisation as the 21st century progresses, and asks the question: Is humanity on the path to destruction? War, famine,plague, global warming, nuclear meltdown: all have the potential to extinguish life on Earth forever. While our technology can help us overcome these perils, that same technology may itself contain the seeds of catastrophe. In fifty compelling essays, including entries on mega-tsunamis, a new ice-age, a giant meteor strike, nuclear holocaust and nanotechnology running amok, Doomsday depicts the possible scenarios of annihilation to come and assesses our chances of survival, if any.
