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.

Four people are born every second of every day. Conservative estimates suggest that there will be 10 billion people on Earth by 2050. That is billions more than the natural resources of our planet can sustain without big changes in how we use and manage them. So what happens when vast population growth endangers the world’s food supplies? Or our water? Our energy needs, climate, or environment? Or the planet’s biodiversity? What happens if some or all of these become critical at once? Just what is our future? In Tipping Point for Planet Earth, world-renowned scientists Anthony Barnosky and Elizabeth Hadly explain the growing threats to humanity as the planet edges toward resource wars for remaining space, food, oil, and water. And as they show, these wars are not the nightmares of a dystopian future, but are already happening today. Finally, they ask: at what point will inaction lead to the break-up of the intricate workings of the global society? The planet is in danger now, but the solutions, as Barnosky and Hadly show, are still available. We still have the chance to avoid the tipping point and to make the future better. But this window of opportunity will shut within ten to twenty years. Tipping Point for Planet Earth is the wake-up call we need.

" ... Concise explanations and descriptions - easily read and readily understood - of what we know of the chain of events and processes that connect the Sun to the Earth, with special emphasis on space weather and Sun-Climate."--Dear Reader.

A global pandemic has brought humanity close to extinction. All has been lost--philosophy, religion, art, science, technology--and the culture that took millennia to build has been forgotten. Coupled with an environmental calamity that has eradicated most species and destabilized Earth's atmosphere, humanity struggles to survive.Tens of thousands of years pass. The earth slowly recovers its balance, and humanity begins to prosper. Evolution reoccupies niches with new creatures, and starting with a clean slate, the People must rediscover their place within the inconceivably vast cosmos they perceive around them.

This illustrated book for young readers explores our fascination with the moon from ancient lunar theories to the Apollo 11 landing and beyond. Since the dawn of human existence, people have gazed up at the night sky and wondered about the moon. In Our Moon, Elaine Scott presents a concise history of what the moon has meant to humanity over the centuries, from ancient lunar legends and theories to the revolutionary discoveries of Galileo. She then shares a wealth of captivating, kid-friendly overview of what we know about the moon today. Scott covers everything from the newest theories on how the moon formed, to the recent, startling discovery of water on its surface and the very real possibility of future moon colonies. Illustrated with stunning, full-color photographs and packed with fun facts, this is the most complete and up-to-date book available on the moon. A glossary, bibliography, and index are included.

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.
