"The first part discusses the origins of everything, from the Big Bang to humankind. It follows the long course of evolution - from original matter to the formation of more complex structures, from the furthest galaxies to the nearest stars, from planets to organic molecules, from the first and most elementary forms of life through to the reptiles, the dinosaurs and the advent of man. The second part traces the history of the Earth and evaluates the risks of extinction in the future as predicted by scientists. Is the Earth the only habitable planet in the Universe? This question initiates the discussion on the importance of the Earth's position in the solar system and the significance of our geologically alive planet. The final part is dedicated to the search for extraterrestrial beings with identifiable life forms. It also describes attempts for searching, from the past to the near future." --Publisher's website.

“A definitive guide to astronomy’s hottest field.” —The Economist Since its formation nearly five billion years ago, our planet has been the sole living world in a vast and silent universe. But over the past two decades, astronomers have discovered thousands of “exoplanets,” including some that could be similar to our own world, and the pace of discovery is accelerating. In a fascinating account of this unfolding revolution, Lee Billings draws on interviews with the world’s top experts in the search for life beyond earth. He reveals how the search for exoplanets is not only a scientific challenge, but also a reflection of our culture’s timeless hopes, dreams, and fears.

This is a book on planets: Solar system planets and dwarf planets. And planets outside our solar system – exoplanets. How did they form? What types of planets are there and what do they have in common? How do they differ? What do we know about their atmospheres – if they have one? What are the conditions for life and on which planets may they be met? And what’s the origin of life on Earth and how did it form? You will understand how rare the solar system, the Earth and hence life is. This is also a book on stars. The first and second generation of stars in the Universe. But in particular also on the link between planets and stars – brown dwarfs. Their atmospheric properties and similarities with giant exoplanets. All these fascinating questions will be answered in a non-technical manner. But those of you who want to know a bit more may look up the relevant mathematical relationships in appendices.

This work presents astronomy from the standpoint of estimating the likelihood of extraterrestrial life and the possibilities of finding it. Thus the text covers the fundamentals of astronomy, the origins and evolution of life on Earth, the formation and present state of the sun's family of planets and moons, and the opportunities and limitations on interstellar travel and communication. The book's final chapters deal with the issue of UFO reports and with Enrico Fermi's famous question, where is everybody? The book is suitable for college freshmen with no background in mathematics.

'An expert romp through the science of extraterrestrial life.' Adam Rutherford Today we know of only a single planet that hosts life: the Earth. But across a Universe of at least 100 billion possibly habitable worlds, surely our planet isn't the only one that is just right for life? As Goldilocks was searching for the perfect bowl of porridge, astrobiologists are searching for conditions throughout the Universe that are just right for life as we currently know it to exist. With the Earth as our guide, the search has begun for similar worlds sitting at the perfect distance from their Sun Â? within the aptly named 'Goldilocks Zone' Â? that would enable them to keep water as a liquid on their surface and therefore perhaps support a thriving biosphere. What might life look like on other worlds? It is possible to make best-guesses using facts rooted in biology, physics and chemistry, and by studying 'extremophiles' on Earth, organisms such as the near-indestructible water bears that can survive in the harshest conditions that Earth, and even space, can offer. Goldilocks and the Water Bears is a tale of the origins and evolution of life, and the quest to find it on other planets, on moons, in other galaxies, and throughout the Universe.

As civil space policies and programs have evolved, the geopolitical environment has changed dramatically. Although the U.S. space program was originally driven in large part by competition with the Soviet Union, the nation now finds itself in a post-Cold War world in which many nations have established, or are aspiring to develop, independent space capabilities. Furthermore discoveries from developments in the first 50 years of the space age have led to an explosion of scientific and engineering knowledge and practical applications of space technology. The private sector has also been developing, fielding, and expanding the commercial use of space-based technology and systems. Recognizing the new national and international context for space activities, America's Future in Space is meant to advise the nation on key goals and critical issues in 21st century U.S. civil space policy.
