What was our planet like in years past? How has our civilization affected Earth and its ecology? Harvesting Space for a Greener Planet, the Second Edition of Paradise Regained: The Regreening of the Earth, begins by discussing these questions, and then generates a scenario for the restoration of Earth. It introduces new and innovative ideas on how we could use the Solar System and its resources for terrestrial benefit. The environmental challenges that face us today cannot be resolved by conservation and current technologies alone. Harvesting Space highlights the risk of humankind's future extinction from environmental degradation. Population growth, global climate change, and maintaining sustainability of habitats for wildlife are all considered, among other issues. Rather than losing heart, we need to realize that the solutions to these problems lie in being good stewards of the planet and in the development of space. Not only will the solutions offered here avert a crisis, they will also provide the basis for continued technological and societal progress. Tapping the resources of near-Earth asteroids will lead to methods of diverting those asteroids that threaten Earth. Space-based terrestrial power generation systems will work synergistically with Earth-based conservation. This book needs to be read urgently and widely, if we are to save ourselves from environmental disaster, reduce the risk of catastrophic cosmic impacts, and build a prosperous and sustainable future for all the creatures of Earth.

Albert Einstein's General Theory of Relativity is possibly the most perfect intellectual achievement in modern physics. Anything that involves gravity, the force that powers everything on the largest, hottest or densest of scales, can be explained by it. From the moment Einstein first proposed the theory in 1915, it was received with enthusiasm yet also with tremendous resistance, and for the following ninety years was the source of a series of feuds, vendettas, ideological battles and international collaborations featuring a colourful cast of characters. A gripping, colourfully told story, A Perfect Theory entangles itself with the flashpoints of modern history. In this first complete popular history of the theory, Pedro G. Ferreira shows how the theory has informed our understanding of exactly what the universe is made of and how much is still undiscovered: from the work of the giant telescopes in the deserts of Chile to the way in which the latest work on black holes is providing a fresh, new perspective on what space and time are truly made of. As we near the first centenary of Einstein's iconic theory, scientists the world over are wondering once again if we have reached the limits of the theory and just how much of the universe's future it can explain.

"And it was then that all these kinds of things thus established received their shapes from the Ordering One, through the action of Ideas of Numbers" (Plato: in Timaeus). Indeed, the Hamilton's 'Principle of Least Action' is a mathematical discrimination between inorganic and organic systems. The geometrical progression of organic life has the property of producing by simple addition, a succession of numbers or similar shapes making the homothetic (gnomonic) growth-work by 'imbibition' (from inside outwards). Whereas, inorganic matters (crystals, snowflakes, rocks) grow by 'agglutination' (from outside inwards) and final distribution of energy to cause no further motion. While in inorganic growth (hexagonal), the Principle of Least Actions tends to save energy, in organic or gnomonic growth (pentagonal) there is a tendency to save the substance. Involving the avid travelers "father jaguar and the cub," this tourbook of the "snow gallery" mathematically and geometrically analyzes the deposition, aggregation, capacitance, and velocity of the snowflake formation, vis a vis the hexagonal (honeycomb) tendency. When the tour is over, the cub classifies his most favorite snowflakes, giving them names.

A passion for star-gazing often starts in a modest way, with a small telescope. For some, that modest beginning becomes a theme that resonates through a lifetime. Mr. Olcott's Skies is the story of one such beginning, and of how a small telescope and an old book set the author on a long and often indirect road to the stars. It's the tale of a journey that has only just begun, and of the discovery that you really do need to look back the way you've come, to understand where you are.

Bang! Space, time, matter...the Universe was born 13.7 billion years ago. Infinitely small at first, it expanded more rapidly than anyone can contemplate. Brian May, Patrick Moore and Chris Lintott explain how all this came about, from the moment when time and space came into existence, to the formation of the first stars, galaxies and planets, and to the evolution of human beings able to contemplate our own origins and ultimate destiny. Then on towards that destiny in the infinite future, long after the Earth has been consumed by the Red Giant Sun. The story is told in clear, straight forward terms, in the strict order in which the events happened, and uses no mathematics. "Bang!" is an amazing story and this newly revised text brings it "Bang!" up to date. Is it fiction? The authors hope not, since it is based upon lifetimes work by great scientists such as Albert Einstein, Stephen Hawking and hundreds of other brilliant minds. Enjoy, and let your imagination run riot.

What if Earth had several moons or massive rings like Saturn? What if the Sun were but one star in a double-star or triple-star system? What if Earth were the only planet circling the Sun? These and other imaginative scenarios are the subject of Arthur Upgren's inventive book Many Skies: Alternative Histories of the Sun, Moon, Planets, and Stars. Although the night sky as we know it seems eternal and inevitable, Upgren reminds us that, just as easily, it could have been very different. Had the solar system happened to be in the midst of a star cluster, we might have many more bright stars in the sky. Yet had it been located beyond the edge of the Milky Way galaxy, we might have no stars at all. If Venus or Mars had a moon as large as ours, we would be able to view it easily with the unaided eye. Given these or other alternative skies, what might Ptolemy or Copernicus have concluded about the center of the solar system and the Sun? This book not only examines the changes in science that these alternative solar, stellar, and galactic arrangements would have brought, it also explores the different theologies, astrologies, and methods of tracking time that would have developed to reflect them. Our perception of our surroundings, the number of gods we worship, the symbols we use in art and literature, even the way we form nations and empires are all closely tied to our particular (and accidental) placement in the universe. Many Skies, however, is not merely a fanciful play on what might have been. Upgren also explores the actual ways that human interference's such as light pollution are changing the night sky. Our atmosphere, he warns, will appear very different if we have a belt of debris circling the globe and blotting out the stars, as will happen if advertisers one day pollute space with brilliant satellites displaying their products. From fanciful to foreboding, the scenarios in Many Skies will both delight and inspire reflection, reminding us that ours is but one of many world views based on our experience of a universe that is as much a product of accident as it is of intention.

Our nearest celestial neighbour, the Moon, has always been the most conspicuous feature in our night sky. It has compelled observers since the dawn of humankind, and all have tried to make sense in their own ways of the puzzles it poses and the questions it raises. It provided our ancient ancestors with one of the earliest means of keeping and measuring time, and many early religions had cults that worshipped the Moon. It regulates the tides and has been held accountable for numerous human conditions, most notably madness and psychological disorders. Drawing on many years of practical observation, Bill Leatherbarrow provides an illuminating insight into the history and evolution of this enthralling astronomical body. He describes how and why the study of the Moon has evolved, particularly in the age of the telescope, and offers an overview of developments in lunar science since the advent of the space age. Leatherbarrow also provides practical advice on how to make your own observations of the Moon. Extensively illustrated with images of the lunar surface, The Moon is an accessible introduction that will appeal to both amateur and professional astronomers and all those fascinated by Earth's natural satellite.

"What if?" questions have always stimulated people to think in new ways. "What if the Earth Had Two Moons "leads us on a fascinating 10 world journey exploring what the Earth would be like if conditions in the universe were slightly different. The answer: Earth would be different, often in ways that would surprise us. The title chapter, for example, gives us a second moon orbiting closer to Earth than the one we have now. The night sky is a lot brighter, but not forever. Eventually the moons collide, with one more-massive moon emerging after a period during which Earth has a Saturn-like ring. The scenarios also shed new light on the burgeoning search for life on planets orbiting other stars.

Appealing to adult and young adult alike, this book is a fascinating journey through physics and astronomy, and follows on the author's previous bestseller, "What if the Moon Didn't Exist?, "with completely new scenarios backed by the latest astronomical research.

Ever since the serendipitous discovery of planet Uranus in 1871, astronomers have been hunting for new worlds in the outer regions of our solar system. This exciting and ongoing quest culminated recently in the discovery of hundreds of ice dwarfs in the Kuiper belt, robbed Pluto from its 'planet' status, and led to a better understanding of the origin of the solar system.

This timely book reads like a scientific 'who done it', going from the heights of discovery to the depths of disappointment in the hunt for 'Planet X'. Based on many personal interviews with astronomers, the well-known science writer Govert Schilling introduces the heroes in the race to be the first in finding another world, bigger than Pluto.

According to a recent survey, the most popular question about science from the general public was: what came before the Big Bang? We all know on some level what the Big Bang is, but we don't know how it became the accepted theory, or how we might know what came before. In "Before the Big Bang", Brian Clegg (the critically acclaimed author of "Upgrade Me" and "The God Effect") explores the history of this remarkable concept. From the earliest creation myths, through Hershel's realization that the Milky Way was one of many galaxies, to ongoing debates about Black Holes, this is an incredible look at the origins of the universe and the many theories that led to the acceptance of the Big Bang. But the idea of Big Bang doesn't so much answer questions as raise new ones. Clegg challenges the notion of the 'Big Bang' itself, and raises the deep philosophical question of why we might want to rethink the origin of the universe. This is popular science at its best, exploratory, controversial, and utterly engrossing.

When I became the producer of the Sky at Night in 2002, I was given some friendly advice: "It's a quiet little programme, not much happens in astronomy." How wrong they were! It's been a hectic and enthralling time ever since:, with missions arriving at distant planets; new discoveries in our Universe; and leaps in technology, which mean amateurs can take pictures as good as the Hubble Space Telescope. What a privilege it is to work on a programme with such a huge heritage! I am constantly amazed looking back at the flotilla of excellent programmes which have gone out over the past five decades. The Sky at Night has always been at the sharp end of science broadcasting, whether it's showing the first view from the far side of the Moon or pictures of a new comet which has swept into our sky. Viewers can depend on Sir Patrick to tell them the latest news and explain what it means. It's an outstanding achievement and Sir Patrick still holds the world record for being the same presenter on the longest running TV programme. Our guests love coming down to Farthings, Sir Patrick's home. For them, me- ing him is like meeting their astronomical hero. Over the past five decades, the Sky at Night has managed to talk to the space scientists and astronomers making the landmark discoveries. No matter how busy they are, they make room for Sir Patrick.

As the new industry of space tourism begins its rapid expansion phase with the introduction of Sir Richard Branson's Virgin Galactic spaceflights around end 2010/early 2011, the reader of this book will gain an understanding of how it reached this point. The story, told through a well-selected collection of photographs, is of a succession of developments and risk-taking that goes back a century to the almost simultaneous start of both aviation and rocketry. The key people in this story are highlighted - and are given The Wright Stuff Awards - for their contribution. Many of them are surprising, in that they would not previously been associated with space tourism, but the author makes their contributions clear. Readers will learn that their tickets to space have been made possible not just by the efforts of entrepreneurs and engineers, but also just as importantly by artists, regulators, politicians and some of the earliest aviators - all of whom had The Wright Stuff.

Was the Apollo 11 Moon landing faked? Many people argue that in the 1960s the United States lacked both the ability and technology required to put a man on the Moon. At the height of the Cold War and with Kennedy's promise to put a man on the Moon before the end of the decade many have questioned the official story. Was the Moon landing one of the greatest ever hoaxes or did NASA really put two men down on the moon in 1969? This detailed book examines the evidence, the photographs and the people to find out the truth. What really happened and did the Eagle ever really land?
