Synopsis The Search for Life's Origins by : National Research Council
The field of planetary biology and chemical evolution draws together experts in astronomy, paleobiology, biochemistry, and space science who work together to understand the evolution of living systems. This field has made exciting discoveries that shed light on how organic compounds came together to form self-replicating molecules-the origin of life. This volume updates that progress and offers recommendations on research programs-including an ambitious effort centered on Mars-to advance the field over the next 10 to 15 years. The book presents a wide range of data and research results on these and other issues: The biogenic elements and their interaction in the interstellar clouds and in solar nebulae. Early planetary environments and the conditions that lead to the origin of life. The evolution of cellular and multicellular life. The search for life outside the solar system. This volume will become required reading for anyone involved in the search for life's beginnings-including exobiologists, geoscientists, planetary scientists, and U.S. space and science policymakers.

Synopsis Alien Oceans by : Kevin Hand
Inside the epic quest to find life on the water-rich moons at the outer reaches of the solar system Where is the best place to find life beyond Earth? We often look to Mars as the most promising site in our solar system, but recent scientific missions have revealed that some of the most habitable real estate may actually lie farther away. Beneath the frozen crusts of several of the small, ice-covered moons of Jupiter and Saturn lurk vast oceans that may have existed for as long as Earth, and together may contain more than fifty times its total volume of liquid water. Could there be organisms living in their depths? Alien Oceans reveals the science behind the thrilling quest to find out. Kevin Peter Hand is one of today's leading NASA scientists, and his pioneering research has taken him on expeditions around the world. In this captivating account of scientific discovery, he brings together insights from planetary science, biology, and the adventures of scientists like himself to explain how we know that oceans exist within moons of the outer solar system, like Europa, Titan, and Enceladus. He shows how the exploration of Earth's oceans is informing our understanding of the potential habitability of these icy moons, and draws lessons from what we have learned about the origins of life on our own planet to consider how life could arise on these distant worlds. Alien Oceans describes what lies ahead in our search for life in our solar system and beyond, setting the stage for the transformative discoveries that may await us.

Synopsis The Search for Aliens: A Rough Guide to Life on Other Worlds by : Rough Guides
The Search for Aliens: A Rough Guide to Life on Other Worlds provides the first vivid and completely accessible guide to the most exciting field of modern science: the search for extraterrestrial life. All the latest research projects are identified, located and described; everything from radio dishes searching for intelligent alien signals to deep oceanic research, seeking links between terrestrial organisms and the broader cosmos. It also explores the idea of Panspermia, the notion that asteroids and comets brought biological building blocks to the early earth, plus exactly which factors must align for life to arise across our galaxy and the universe. The Search for Aliens: A Rough Guide to Life on Other Worlds explains why we may be closer than ever to finding out the answer to the question: is there any life beyond life on earth? Now available in ePub format.

Synopsis The Sirens of Mars by : Sarah Stewart Johnson
“Sarah Stewart Johnson interweaves her own coming-of-age story as a planetary scientist with a vivid history of the exploration of Mars in this celebration of human curiosity, passion, and perseverance.”—Alan Lightman, author of Einstein’s Dreams WINNER OF THE PHI BETA KAPPA AWARD FOR SCIENCE • NAMED ONE OF THE BEST BOOKS OF THE YEAR BY The New York Times Book Review • Times (UK) • Library Journal “Lovely . . . Johnson’s prose swirls with lyrical wonder, as varied and multihued as the apricot deserts, butterscotch skies and blue sunsets of Mars.”—Anthony Doerr, The New York Times Book Review Mars was once similar to Earth, but today there are no rivers, no lakes, no oceans. Coated in red dust, the terrain is bewilderingly empty. And yet multiple spacecraft are circling Mars, sweeping over Terra Sabaea, Syrtis Major, the dunes of Elysium, and Mare Sirenum—on the brink, perhaps, of a staggering find, one that would inspire humankind as much as any discovery in the history of modern science. In this beautifully observed, deeply personal book, Georgetown scientist Sarah Stewart Johnson tells the story of how she and other researchers have scoured Mars for signs of life, transforming the planet from a distant point of light into a world of its own. Johnson’s fascination with Mars began as a child in Kentucky, turning over rocks with her father and looking at planets in the night sky. She now conducts fieldwork in some of Earth’s most hostile environments, such as the Dry Valleys of Antarctica and the salt flats of Western Australia, developing methods for detecting life on other worlds. Here, with poetic precision, she interlaces her own personal journey—as a female scientist and a mother—with tales of other seekers, from Percival Lowell, who was convinced that a utopian society existed on Mars, to Audouin Dollfus, who tried to carry out astronomical observations from a stratospheric balloon. In the process, she shows how the story of Mars is also a story about Earth: This other world has been our mirror, our foil, a telltale reflection of our own anxieties and yearnings. Empathetic and evocative, The Sirens of Mars offers an unlikely natural history of a place where no human has ever set foot, while providing a vivid portrait of our quest to defy our isolation in the cosmos.

Synopsis Exoplanets by : Michael E. Summers
The past few years have seen an incredible explosion in our knowledge of the universe. Since its 2009 launch, the Kepler satellite has discovered more than two thousand exoplanets, or planets outside our solar system. More exoplanets are being discovered all the time, and even more remarkable than the sheer number of exoplanets is their variety. In Exoplanets, astronomer Michael Summers and physicist James Trefil explore these remarkable recent discoveries: planets revolving around pulsars, planets made of diamond, planets that are mostly water, and numerous rogue planets wandering through the emptiness of space. This captivating book reveals the latest discoveries and argues that the incredible richness and complexity we are finding necessitates a change in our questions and mental paradigms. In short, we have to change how we think about the universe and our place in it, because it is stranger and more interesting than we could have imagined.

Synopsis Exoplanets by : Donald Goldsmith
“How do alien, faraway worlds reveal their existence to Earthlings? Let Donald Goldsmith count the ways. As an experienced astronomer and a gifted storyteller, he is the perfect person to chronicle the ongoing hunt for planets of other stars.” —Dava Sobel Astronomers have recently discovered thousands of planets that orbit stars throughout our Milky Way galaxy. With his characteristic wit and style, Donald Goldsmith presents the science of exoplanets and the search for extraterrestrial life in a way that Earthlings with little background in astronomy or astrophysics can understand and enjoy. Much of what has captured the imagination of planetary scientists and the public is the unexpected strangeness of these distant worlds, which bear little resemblance to the planets in our solar system. The sizes, masses, and orbits of exoplanets detected so far raise new questions about how planets form and evolve. Still more tantalizing are the efforts to determine which exoplanets might support life. Astronomers are steadily improving their means of examining these planets’ atmospheres and surfaces, with the help of advanced spacecraft sent into orbits a million miles from Earth. These instruments will provide better observations of planetary systems in orbit around the dim red stars that throng the Milky Way. Previously spurned as too faint to support life, these cool stars turn out to possess myriad planets nestled close enough to maintain Earthlike temperatures. The quest to find other worlds brims with possibility. Exoplanets shows how astronomers have broadened our planetary horizons, and suggests what may come next, including the ultimate discovery: life beyond our home planet.
