Available in PDF, EPUB and Kindle. Book excerpt: Barrie Jones addresses the question "are we alone?", which is one of the most frequently asked questions by scientists and non-scientists alike. In The Search for Life Continued, this question is addressed scientifically, and the author is not afraid to include speculation. Indeed, the author believes beyond reasonable doubt that we are not alone and this belief is based firmly on frontier science of the most imaginative kind. The author concentrates on planetary systems beyond our own but starts with life on Earth, which is the only life we know to exist, and which provides guidance on how best to search for life elsewhere. Planets are the most likely abode of life and so we start the quest with the search for planets beyond the Solar System – exoplanets. The methods of searching are outlined and the nature of hundreds of exoplanetary systems so far discovered described. In the near future we expect to discover habitable Earth-like planets. But are they actually inhabited? How could we tell? All will be revealed. This full color book is written for everybody who wants to stay in close contact with the latest on possible life on other planets.

This book was released on 2019-03-20 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.

Book excerpt: “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.

Download or read book Science Culture and the Search for Life on Other Worlds written by John W. Traphagan and published by Springer. This book was released on 2016-08-26 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores humanity’s thoughts and ideas about extraterrestrial life, paying close attention to the ways science and culture interact with one another to create a context of imagination and discovery related to life on other worlds. Despite the recent explosion in our knowledge of other planets and the seeming era of discovery in which we live, to date we have found no concrete evidence that we are not alone. Our thinking about life on other worlds has been and remains the product of a combination of scientific investigation and human imagination shaped by cultural values--particularly values of exploration and discovery connected to American society. The rapid growth in our awareness of other worlds makes this a crucial moment to think about and assess the influence of cultural values on the scientific search for extraterrestrial life. Here the author considers the junction of science and culture with a focus on two main themes: (1) the underlying assumptions, many of which are tacitly based upon cultural values common in American society, that have shaped the ways researchers in astrobiology and SETI have conceptualized the nature of their endeavor and represented ideas about the potential influence contact might have on human civilization, and (2) the empirical evidence we can access as a way of thinking about the social impact that contact with alien intelligence might have for humanity.

Available in PDF, EPUB and Kindle. Book excerpt: "A cogent, engaging history of humanity's most ambitious quest--seeking outward for other minds."--David Brin, author of Existence "A fascinating perspective on humankind's obsession for knowing if there is anyone else out there."--Gerrit L. Verschuur, author of The Invisible Universe: The Story of Radio Astronomy "Squeri has written what will likely be the definitive history of the early days of SETI that includes profiles of some of its leading characters."--Ben Zuckerman, coeditor of Extraterrestrials: Where Are They? "An insightful history that explores the scientific foundations of the modern-day search for our place in the cosmos. Waiting for Contact delivers unparalleled access to the inner history of SETI and invites us to ride along on the journey to answer one of science's ultimate questions: Are we alone?"--Douglas Vakoch, president, METI International "Waiting for Contact is a balanced account, telling the tale of the search for extraterrestrial intelligence without the overpromise usually trumpeted by enthusiastic proponents and the hyperventilation so commonly added by UFO enthusiasts. If you are simply interested in the history, unvarnished by an agenda, you'll enjoy this book."--Don Lincoln, author of Alien Universe: Extraterrestrial Life in Our Minds and in the Cosmos Imagine a network of extraterrestrials in radio contact with each other across the universe, superior beings who hail from advanced civilizations quadrillions of miles away, just waiting for Earth to tune in. Some people believe it’s only a matter of time before we discover the right "station." Waiting for Contact tells the story of the Search for Extraterrestrial Intelligence (SETI) movement, which emerged in 1959 as astronomers began using radio telescopes to listen for messages from space. New technological developments turned what once was speculation into science. Boosted by support from Frank Drake, Philip Morrison, Carl Sagan, and the genre of science fiction, the SETI movement gained followers and continues to capture imaginations today. In this one-of-a-kind history, Lawrence Squeri looks at the people, reasons, goals, and mindsets behind SETI. He shows how it started as an expression of the times, a way out of Cold War angst with hope for a better world. SETI's early advocates thought that with guidance from technically and ethically advanced outsiders, humanity might learn how to avoid horrors like nuclear annihilation and societal collapse from overpopulation. Some hoped that good news from outer space might reveal a cure for cancer or even the secret of immortality. Squeri also describes the challenges SETI has faced over the years: the struggle to be taken seriously by the scientific community and by NASA, competition for access to radio telescopes, perpetual lack of funding, and opposition from influential politicians. He covers the rise and fall of Soviet SETI and the few rare meetings between Soviet and American astronomers. Despite many setbacks, the movement pressed forward with the aid of private donations and developed outreach programs. Volunteers can now help search for new civilizations on their personal computers by joining the SETI@Home project. Today, SETI researchers continue to see themselves as explorers. They often identify with Columbus, and just as Columbus never realized the full implications of his discovery, we cannot predict what will happen if contact is made. This book points out that if, against all expectations, the embattled SETI movement finally succeeds, the long-awaited first signal picked up by its radio antennas will usher the greatest shift in human history. A new adventure will begin. Lawrence Squeri is professor emeritus of history at East Stroudsburg University.

Book excerpt: "What is the origin of the universe? Are we alone in the Universe?" Using clear and plain language, the author explores these two interesting scientific-philosophical themes with a broad range of studies, including astronomy, cosmology, chemistry, biology, geology and planet science. The first part discusses the origins of everything, from the Big Bang to humankind. It follows the long course of evolution — from original matter to the formation of more complex structures, from the furthest galaxies to the nearest stars, from planets to organic molecules, from the first and most elementary forms of life through to the reptiles, the dinosaurs and the advent of man. The second part traces the history of the Earth and evaluates the risks of extinction in the future as predicted by scientists. Is the Earth the only habitable planet in the Universe? This question initiates the discussion on the importance of the Earth's position in the solar system and the significance of our geologically alive planet. The final part is dedicated to the search for extraterrestrial beings with identifiable life forms. It also describes attempts for searching, from the past to the near future. This remarkable book provides the best answers we have to the epic questions about us and our place in the universe.

Download or read book Science Society and the Search for Life in the Universe written by Bruce M. Jakosky and published by University of Arizona Press. This book was released on 2022-10-18 with total page 162 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 life’s 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 today’s 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 public’s 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 “Big Questions” 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 public’s 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.
Download or read book A Journey with Fred Hoyle written by Chandra Wickramasinghe and published by World Scientific. This book was released on 2005-01-11 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: ' This is the story of the author's unique scientific journey with one of the most remarkable men of 20th century science. The journey begins in Sri Lanka, the author's native country, with his childhood acquaintance with Fred Hoyle's writings. The action then moves to Cambridge, where the famous Hoyle–Wickramasinghe collaborations begin. A research programme which was started in 1962 on the carbonaceous nature of interstellar dust leads, over the next two decades, to developments that are continued in both Cambridge and Cardiff. These developments prompt Hoyle and the author to postulate the organic theory of cosmic dust (which is now generally accepted), and then to challenge one of the most cherished paradigms of contemporary science — the theory that life originated on Earth in a warm primordial soup. A Journey with Fred Hoyle is an intriguing book that traces the progress of a collaboration spanning 40 years, through a sequence of personal reflections, anecdotes and reminiscences. Ideas that were thought heretical 25 years ago are now quietly slipping into the domain of orthodox science.

Download or read book Are We Being Watched The Search for Life in the Cosmos written by Paul Murdin and published by Thames & Hudson. This book was released on 2013-04-01 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: An engaging exploration with renowned astronomer Paul Murdin of how life emerged on Earth—and the possibilities that it exists elsewhere There is no more fascinating question than whether or not we are alone in a vast universe. Here, Paul Murdin applies the latest scientific discoveries and theories to inquire whether life exists on other planets and, if so, what forms it might take. Could there be somewhere life as advanced as here on Earth, or are we more likely to find primitive life-forms? Or are we the sole living organisms in a desolate and boundless cosmos? Professor Murdin invites us to join him in exploring an extraordinary array of evidence to determine if there is life elsewhere in the cosmos. He examines the case for life on Mars and Europa and asks whether on Enceladus or Titan we might find the “warm little” pond that Darwin speculated was where life began here on Earth. Describing the cosmic habitats that produce the alien worlds of our solar system and others, he examines the chances of finding life and the prospects for successful communication with an extraterrestrial intelligence.

Available in PDF, EPUB and Kindle. Book excerpt: An insider's look at the cutting-edge science of today's planet hunters In Strange New Worlds, renowned astronomer Ray Jayawardhana brings news from the front lines of the epic quest to find planets—and alien life—beyond our solar system. Only in the past two decades, after millennia of speculation, have astronomers begun to discover planets around other stars—thousands in fact. Now they are closer than ever to unraveling distant twins of the Earth. In this book, Jayawardhana vividly recounts the stories of the scientists and the remarkable breakthroughs that have ushered in this extraordinary age of exploration. He describes the latest findings--including his own—that are challenging our view of the cosmos and casting new light on the origins and evolution of planets and planetary systems. He reveals how technology is rapidly advancing to support direct observations of Jupiter-like gas giants and super-Earths—rocky planets with several times the mass of our own planet—and how astronomers use biomarkers to seek possible life on other worlds. Strange New Worlds provides an insider's look at the cutting-edge science of today's planet hunters, our prospects for discovering alien life, and the debates and controversies at the forefront of extrasolar-planet research. In a new afterword, Jayawardhana explains some of the most recent developments as we search for the first clues of life on other planets.
