All humans share three origins: the beginning of our individual lives, the appearance of life on Earth, and the formation of our planetary home. Life through Time and Space brings together the latest discoveries in both biology and astronomy to examine our deepest questions about where we came from, where we are going, and whether we are alone in the cosmos. A distinctive voice in the growing field of astrobiology, Wallace Arthur combines embryological, evolutionary, and cosmological perspectives to tell the story of life on Earth and its potential to exist elsewhere in the universe. He guides us on a journey through the myriad events that started with the big bang and led to the universe we inhabit today. Along the way, readers learn about the evolution of life from a primordial soup of organic molecules to complex plants and animals, about Earth’s geological transformation from barren rock to diverse ecosystems, and about human development from embryo to infant to adult. Arthur looks closely at the history of mass extinctions and the prospects for humanity’s future on our precious planet. Do intelligent aliens exist on a distant planet in the Milky Way, sharing the three origins that characterize all life on Earth? In addressing this question, Life through Time and Space tackles the many riddles of our place and fate in the universe that have intrigued human beings since they first gazed in wonder at the nighttime sky.

The acclaimed author of Einstein’s Dreams tackles "big questions like the origin of the universe and the nature of consciousness ... in an entertaining and easily digestible way” (Wall Street Journal) with a collection of meditative essays on the possibilities—and impossibilities—of nothingness and infinity, and how our place in the cosmos falls somewhere in between. Can space be divided into smaller and smaller units, ad infinitum? Does space extend to larger and larger regions, on and on to infinity? Is consciousness reducible to the material brain and its neurons? What was the origin of life, and can biologists create life from scratch in the lab? Physicist and novelist Alan Lightman, whom The Washington Post has called “the poet laureate of science writers,” explores these questions and more—from the anatomy of a smile to the capriciousness of memory to the specialness of life in the universe to what came before the Big Bang. Probable Impossibilities is a deeply engaged consideration of what we know of the universe, of life and the mind, and of things vastly larger and smaller than ourselves.

Life is a property of the universe. We may not know how it began or where else it exists, but we have come to know a great deal about how it relates to stars, planets, and the larger cosmos. In clear and compelling terms, this book shows how the emerging field of astrobiology investigates the nature of life in space. How did life begin? How common is it? Where do we fit in? These are the important questions that astrobiology seeks to answer. A truly interdisciplinary endeavor, astrobiology looks at the evidence of astronomy, biology, physics, chemistry, and a host of other fields. A grand narrative emerges, beginning from the smallest, most common particles yet producing amazing complexity and order. Lucas Mix is a congenial guide through the depths of astrobiology, exploring how the presence of planets around other stars affects our knowledge of our own; how water, carbon, and electrons interact to form life as we know it; and how the processes of evolution and entropy act upon every living thing. This book also reveals that our understanding and our context are deeply intertwined. It shows how much astrobiology can tell us about who we are—as a planet, as a species, and as individuals.

He walked on the Moon. He flew six space missions in three different programs--more than any other human. He served with NASA for more than four decades. His peers called him the "astronaut's astronaut." Enthusiasts of space exploration have long waited for John Young to tell the story of his two Gemini flights, his two Apollo missions, the first-ever Space Shuttle flight, and the first Spacelab mission. Forever Young delivers all that and more: Young's personal journey from engineering graduate to fighter pilot, to test pilot, to astronaut, to high NASA official, to clear-headed predictor of the fate of Planet Earth. Young, with the assistance of internationally distinguished aerospace historian James Hansen, recounts the great episodes of his amazing flying career in fascinating detail and with wry humor. He portrays astronauts as ordinary human beings and NASA as an institution with the same ups and downs as other major bureaucracies. He frankly discusses the risks of space travel, including what went wrong with the Challenger and Columbia shuttles. Forever Young is one of the last memoirs produced by an early American astronaut. It is the first memoir written by a chief of the NASA astronaut corps. Young's experiences and candor make this book indispensable to everyone interested in the U.S. space program.

An argument that we have a moral duty to explore other planets and solar systems--because human life on Earth has an expiration date. Inevitably, life on Earth will come to an end, whether by climate disaster, cataclysmic war, or the death of the sun in a few billion years. To avoid extinction, we will have to find a new home planet, perhaps even a new solar system, to inhabit. In this provocative and fascinating book, Christopher Mason argues that we have a moral duty to do just that. As the only species aware that life on Earth has an expiration date, we have a responsibility to act as the shepherd of life-forms--not only for our species but for all species on which we depend and for those still to come (by accidental or designed evolution). Mason argues that the same capacity for ingenuity that has enabled us to build rockets and land on other planets can be applied to redesigning biology so that we can sustainably inhabit those planets. And he lays out a 500-year plan for undertaking the massively ambitious project of reengineering human genetics for life on other worlds. As they are today, our frail human bodies could never survive travel to another habitable planet. Mason describes the toll that long-term space travel took on astronaut Scott Kelly, who returned from a year on the International Space Station with changes to his blood, bones, and genes. Mason proposes a ten-phase, 500-year program that would engineer the genome so that humans can tolerate the extreme environments of outer space--with the ultimate goal of achieving human settlement of new solar systems. He lays out a roadmap of which solar systems to visit first, and merges biotechnology, philosophy, and genetics to offer an unparalleled vision of the universe to come.

A story about the origins of space, time, miracles and more. "Lost in Space" offers a totally unique way for each of its readers to assess their own place in reality. This book is for all those who are in search of life's truths.

When it comes to Mars, the focus is often on how to get there: the rockets, the engines, the fuel. But upon arrival, what will it actually be like? In 2013, Kate Greene moved to Mars. That is, along with five fellow crew members, she embarked on NASA’s first HI-SEAS mission, a simulated Martian environment located on the slopes of Mauna Loa in Hawai'i. For four months she lived, worked, and slept in an isolated geodesic dome, conducting a sleep study on her crew mates and gaining incredible insight into human behavior in tight quarters, as well as the nature of boredom, dreams, and isolation that arise amidst the promise of scientific progress and glory. In Once Upon a Time I Lived on Mars, Greene draws on her experience to contemplate humanity’s broader impulse to explore. The result is a twined story of space and life, of the standard, able-bodied astronaut and Greene’s brother’s disability, of the lag time of interplanetary correspondences and the challenges of a long-distance marriage, of freeze-dried egg powder and fresh pineapple, of departure and return. By asking what kind of wisdom humanity might take to Mars and elsewhere in the Universe, Greene has written a remarkable, wide-ranging examination of our time in space right now, as a pre-Mars species, poised on the edge, readying for launch.

She was the Gu family's notorious ugly girl. Normally, she would pretend to be stupid, but in reality, she was very cunning. He was the most popular man in the city, mysterious and honorable. When her disguise was revealed layer by layer, she pitifully begged for mercy, "Young Master Mu, can we get a divorce?" However, he forcefully announced, "Divorce, unless I die!" ... .... If she wasn't carelessly framed by her elder sister, she wouldn't have voluntarily provoked such a strong man. She had thought that she would live in misery for the rest of her life, but she hadn't thought that he would love her so much. ***
