The world's leading textbook on astrobiology-ideal for an introductory one-semester course and now fully revised and updatedAre we alone in the cosmos? How are scientists seeking signs of life beyond our home planet? Could we colonize other planets, moons, or even other star systems? This introductory textbook, written by a team of four renowned science communicators, educators, and researchers, tells the amazing story of how modern science is seeking the answers to these and other fascinating questions. They are the questions that are at the heart of the highly interdisciplinary field of astrobiology, the study of life in the universe.Written in an accessible, conversational style for anyone intrigued by the possibilities of life in the solar system and beyond, Life in the Universe is an ideal place to start learning about the latest discoveries and unsolved mysteries in the field. From the most recent missions to Saturn's moons and our neighboring planet Mars to revolutionary discoveries of thousands of exoplanets, from the puzzle of life's beginning on Earth to the latest efforts in the search for intelligent life elsewhere, this book captures the imagination and enriches the reader's understanding of how astronomers, planetary scientists, biologists, and other scientists make progress at the cutting edge of this dynamic field. Enriched with a wealth of engaging features, this textbook brings any citizen of the cosmos up to speed with the scientific quest to discover whether we are alone or part of a universe full of life.An acclaimed text designed to inspire students of all backgrounds to explore foundational questions about life in the cosmosCompletely revised and updated to include the latest developments in the field, including recent exploratory space missions to Mars, frontier exoplanet science, research on the origin of life on Earth, and moreEnriched with helpful learning aids, including in-chapter Think about It questions, optional Do the Math and Special Topic boxes, Movie Madness boxes, end-of-chapter exercises and problems, quick quizzes, and much moreSupported by instructor's resources, including an illustration package and test bank, available upon request

The media often portrays our climate future as a choice between bleak and bleaker, which may seem justified given the many impacts of global warming that we are already seeing. But it doesn't have to be that way, because if we understand the science behind global warming, then we can also see a pathway to its solution. In this book, astrophysicist/educator Jeffrey Bennett uses a Q&A format to provide a brief and extremely clear overview of the surprisingly simple basic science behind global warming, of the consequences of this warming, and of solutions that can help us alleviate and eventually reverse those consequences. This will help readers understand how we can in principle create a " post-global warming" future, meaning a future in which today's children will someday be able to talk about global warming as a once-serious problem that we found a way to solve.

Using and Understanding Mathematics: A Quantitative Reasoning Approach prepares students for the mathematics they will encounter in college courses, their future career, and life in general. Its quantitative reasoning approach helps students to build the skills needed to understand major issues in everyday life, and compels students to acquire the problem-solving tools that they will need to think critically about quantitative issues in contemporary society. This program will provide a better teaching and learning experiencefor you and your students. Heres how: The real-world focus turns students attention to the math they will need for college, career, and life. A wide range of exercises and problem types end each unit, making it easy for instructors to create assignments to fit their course goals. Study and review features in every chapter are designed to help students use their time effectively.

It is commonly assumed that if the Sun suddenly turned into a black hole, it would suck Earth and the rest of the planets into oblivion. Yet, as prominent author and astrophysicist Jeffrey Bennett points out, black holes don't suck. With that simple idea in mind, Bennett begins an entertaining introduction to Einstein's theories of relativity, describing the amazing phenomena readers would actually experience if they took a trip to a black hole.The theory of relativity reveals the speed of light as the cosmic speed limit, the mind-bending ideas of time dilation and curvature of spacetime, and what may be the most famous equation in history: E = mc2. Indeed, the theory of relativity shapes much of our modern understanding of the universe. It is not "e;just a theory"e;-every major prediction of relativity has been tested to exquisite precision, and its practical applications include the Global Positioning System (GPS). Amply illustrated and written in clear, accessible prose, Bennett's book proves anyone can grasp the basics of Einstein's ideas. His intuitive, nonmathematical approach gives a wide audience its first real taste of how relativity works and why it is so important to science and the way we view ourselves as human beings.

The quest for extraterrestrial life doesn't happen only in science fiction. This book describes the startling discoveries being made in the very real science of astrobiology, an intriguing new field that blends astronomy, biology, and geology to explore the possibility of life on other planets. Jeffrey Bennett takes readers beyond UFOs to discuss some of the tantalizing questions astrobiologists grapple with every day: What is life and how does it begin? What makes a planet or moon habitable? Is there life on Mars or elsewhere in the solar system? How can life be recognized on distant worlds? Is it likely to be microbial, more biologically complex--or even intelligent? What would such a discovery mean for life here on Earth? Come along on this scientific adventure and learn the astonishing implications of discoveries made in this field for the future of the human race. Bennett, who believes that "e;science is a way of helping people come to agreement,"e; explains how the search for extraterrestrial life can help bridge the divide that sometimes exists between science and religion, defuse public rancor over the teaching of evolution, and quiet the debate over global warming. He likens humanity today to a troubled adolescent teetering on the edge between self-destruction and a future of virtually limitless possibilities. Beyond UFOs shows why the very quest to find alien life can help us to grow up as a species and chart a course for the stars. In a new afterword, Bennett shares the most recent developments in extrasolar research, and discusses how they might further our quest to find alien life.
