Provides facts about Earth, the solar system, and each of the inner and outer planets.

The most outstanding and uniquely curated selection of Mars orbital images ever assembled in one volume. With explanatory captions in twenty-four languages and a gallery of more than 200 images, this distinctive volume brings a timely and clear look at the work of an active NASA mission.

The ancient history of Mars is a tale of cosmic evolution, shaped by eons of geological, climatic, and potentially even biological processes. Billions of years ago, Mars likely had a more Earth-like environment, with flowing water, a thicker atmosphere, and possibly the conditions necessary for life to emerge. Evidence from Martian geology, such as dry river valleys and ancient lake beds, hints at a planet once teeming with liquid water. However, over time, Mars underwent a dramatic transformation, with its atmosphere thinning and surface water disappearing, leaving behind a harsh, arid landscape marked by deserts and enormous canyons. Understanding this ancient history provides crucial insights into the potential habitability of Mars and the search for signs of past life on the Red Planet.

Informed by new planetary discoveries and the findings from recent robotic missions to Mars, Jupiter, and Saturn, scientists are rapidly replacing centuries of speculation about potential extraterrestrial habitats with real knowledge about the possibility of life outside our own biosphere -- if it exists, and where. This second edition of Kevin W. Plaxco and Michael Gross's widely acclaimed text incorporates the latest research in astrobiology to bring readers the most comprehensive, up-to-date, and engaging introduction to the field available. Plaxco and Gross expand their examination of the origin of chemical elements, the developments that made the Universe habitable, and how life continues to be sustained. They discuss in great detail the formation of the first galaxies and stars, the diverse chemistry of the primordial planet, the origins of metabolism, the evolution of complex organisms, and the feedback regulation of Earth's climate. They also explore life in extreme habitats, potential extraterrestrial habitats, and the current status of the search for extraterrestrial life. Weaving together the relevant threads of astronomy, geology, chemistry, biophysics, and microbiology, this broadly accessible introductory text captures the excitement, controversy, and progress of the dynamic young field of astrobiology. New to this edition is a glossary of terms and an epilogue recapping the key unanswered questions, making Astrobiology an ideal primer for students and, indeed, for anyone curious about life and the Universe. Praise for the first edition of Astrobiology "Certainly the most readable introduction to astrobiology now available." -- Chemical and Engineering News "Plaxco and Gross bring us as close to aliens as we can currently get. I recommend this book to anyone interested in science's newest kid on the block." -- Astronomy Now "A good read for all those who are fascinated by the search for extraterrestrial life and the origin of life on our own planet. I shall certainly value it in my own library." -- Chemistry World "An accessible guide to this young and interdisciplinary field." -- Physics World "The fascinating world of extremophiles is well presented, and a broad overview of the searches for evidence of life beyond Earth rounds off the book. The text is liberally illustrated with relevant figures that greatly enhance the content, and entertaining snippets of information detailing the quirks of research in this field nicely supplement the scientific content." -- Astrobiology "A comprehensive yet concise introduction to the field." -- The Space Review

This essay collection explores the life and work of science fiction doyen Ray Bradbury from a variety of perspectives. Noting the impact of the Southwest on Bradbury, some of the essays analyze Bradbury's southwest metaphors: colonial pollution of a pristine ecology, the impacts of a colonial invasion upon an indigenous population, the meeting of cultures with different values and physical aspects. Other essays view Bradbury via the lens of post-colonialism, drawing parallels between such works as The Martian Chronicles and real-life colonialism and its effects. Another essay views Bradbury sociologically, analyzing border issues in his 1947 New Yorker story "I See You Never," written long before the issue of Mexican deportees appeared on the American literary horizon. From the scientific side, four essays by astronomers document how Bradbury formed the minds of many budding scientists with his vision. On August 22, 2012, the Martian landing site of the Curiosity rover in the Gale Crater was named "Bradbury." This honor shows that Bradbury forms a significant link between the worlds of fiction and planetary science.
