Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2006-10-26 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Are we alone in the universe? As humans, are we unique or are we part of a greater cosmic existence? What is lifeÕs future on Earth and beyond? How does life begin and develop? These are age-old questions that have inspired wonder and controversy ever since the first people looked up into the sky. With todayÕs technology, however, we are closer than ever to finding the answers. Astrobiology is the relatively new, but fast growing scientific discipline that involves trying to understand the origin, evolution, and distribution of life within the universe. It is also one of the few scientific disciplines that attracts the publicÕs intense curiosity and attention. This interest stems largely from the deep personal meaning that the possible existence of extraterrestrial life has for so many. Whether this meaning relates to addressing the ÒBig QuestionsÓ of our existence, the possibility of encountering life on other planets, or the potential impact on our understanding of religion, there is no doubt that the public is firmly vested in finding answers. In this broadly accessible introduction to the field, Bruce Jakosky looks at the search for life in the universe not only from a scientific perspective, but also from a distinctly social one. In lucid and engaging prose, he addresses topics including the contradiction between the publicÕs fascination and the meager dialogue that exists between those within the scientific community and those outside of it, and what has become some of the most impassioned political wrangling ever seen in government science funding.

This book was released on 2013-02-26 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Weird indeed, and not a little wonderful.”—Nature In the 1980s and 1990s, in places where no one thought it possible, scientists found organisms they called extremophiles: lovers of extremes. There were bacteria in volcanic hydrothermal vents on the ocean floor, single-celled algae in Antarctic ice floes, and fungi in the cooling pools of nuclear reactors. But might there be life stranger than the most extreme extremophile? Might there be, somewhere, another kind of life entirely? In fact, scientists have hypothesized life that uses ammonia instead of water, life based not in carbon but in silicon, life driven by nuclear chemistry, and life whose very atoms are unlike those in life we know. In recent years some scientists have begun to look for the tamer versions of such life on rock surfaces in the American Southwest, in a “shadow biosphere” that might impinge on the known biosphere, and even deep within human tissue. They have also hypothesized more radical versions that might survive in Martian permafrost, in the cold ethylene lakes on Saturn’s moon Titan, and in the hydrogen-rich atmospheres of giant planets in other solar systems. And they have imagined it in places off those worlds: the exotic ices in comets, the vast spaces between the stars, and—strangest of all—parallel universes. Distilling complex science in clear and lively prose, David Toomey illuminates the research of the biological avant-garde and describes the workings of weird organisms in riveting detail. His chapters feature an unforgettable cast of brilliant scientists and cover everything from problems with our definitions of life to the possibility of intelligent weird life. With wit and understanding that will delight scientists and lay readers alike, Toomey reveals how our current knowledge of life forms may account for only a tiny fraction of what’s really out there.

Available in PDF, EPUB and Kindle. Book excerpt: A fun-filled, highly illustrated, science-based exploration into one of the universe’s greatest mysteries—does life exist beyond Earth?—from bestselling and award-winning author Stacy McAnulty. Spoiler: Scientists haven’t discovered life beyond Earth, not even a single teeny-tiny organism. But there’s a whole lot of outer space, and humans have searched only a fraction of a fraction of it. So do you believe in the possibility of life out there? Or do you think Earth is perfectly unique in its ability to grow organisms? Where Are the Aliens? takes readers on a journey of theories and discoveries, from the big bang and primordial soup, to how the ancient Greeks considered the cosmos, to the technology used today to listen and (possibly!) communicate with far-off exoplanets. Packed with playful illustrations and fascinating factoids, this is the perfect book for anyone who has ever looked up and asked, "What's out there?"

This book was released on 2019-04-20 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: Astrobiology is the study of the origin, evolution, distribution, and future of life in the universe. It is an inherently interdisciplinary field that encompasses astronomy, biology, geology, heliophysics, and planetary science, including complementary laboratory activities and field studies conducted in a wide range of terrestrial environments. Combining inherent scientific interest and public appeal, the search for life in the solar system and beyond provides a scientific rationale for many current and future activities carried out by the National Aeronautics and Science Administration (NASA) and other national and international agencies and organizations. Requested by NASA, this study offers a science strategy for astrobiology that outlines key scientific questions, identifies the most promising research in the field, and indicates the extent to which the mission priorities in existing decadal surveys address the search for life's origin, evolution, distribution, and future in the universe. This report makes recommendations for advancing the research, obtaining the measurements, and realizing NASA's goal to search for signs of life in the universe.

Available in PDF, EPUB and Kindle. Book excerpt: With a focus of the Perseverance rover mission, here is the "Quintessential account of one of humanity’s most intriguing quests" (Pail Halpern, Medium), "A remarkable, timely, and up-to-date account of Mars exploration" (Leonard David, "Space Insider," Space.com). From The War of the Worlds to The Martian and to the amazing photographs sent back by the robotic rovers Curiosity and Opportunity, Mars has excited our imaginations as the most likely other habitat for life in the solar system. Now the Red Planet is coming under scrutiny as never before. As new missions are scheduled to launch this year from the United States and China, and with the European Space Agency's ExoMars mission now scheduled for 2022, this book recounts in full the greatest scientific detective story ever. For the first time in forty years, the missions heading to Mars will look for signs of ancient life on the world next door. It is the latest chapter in an age‑old quest that encompasses myth, false starts, red herrings, and bizarre coincidences—as well as triumphs and heartbreaking failures. This book, by two journalists with deep experience covering space exploration, is the definitive story of how life's discovery has eluded us to date, and how it will be found somewhere and sometime this century. The Search for Life on Mars is based on more than a hundred interviews with experts at NASA’s Jet Propulsion Laboratory and elsewhere, who share their insights and stories. While it looks back to the early Mars missions such as Viking 1 and 2, the book's focus is on the experiments and revelations from the most recent ones—including Curiosity, which continues to explore potentially habitable sites where water was once present, and the Mars Insight lander, which has recorded more than 450 marsquakes since its deployment in late 2018—as well as on the Perseverance and ExoMars rover missions ahead. And the book looks forward to the newest, most exciting frontier of all: the day, not too far away, when humans will land, make the Red Planet their home, and look for life directly.
