Available in PDF, EPUB and Kindle. Book excerpt: An in-depth view of the panspermia hypothesis examined against the latest knowledge of planetary formation and related processes. Panspermia is the concept that life can be passively transported through space on various bodies and seed, habitable planets and moons, which we are beginning to learn may exist in large numbers. It is an old idea, but not popular with those who prefer that life on Earth started on Earth, an alternative, also unproven hypothesis. This book updates the concept of panspermia in the light of new evidence on planet formation, molecular clouds, solar system motions, supernovae ejection mechanisms, etc. Thus, it is to be a book about newly understood prospects for the movement of life through space. The novel approach presented in this book gives new insights into the panspermia theory and its connection with planetary formation and the evolution of galaxies. This offers a good starting point for future research proposals about exolife and a better perspective for empirical scrutiny of panspermia theory. Also, the key to understanding life in the universe is to understand that the planetary formation process is convolved with the evolution of stellar systems in their galactic environment. The book provides the synthesis of all these elements and gives the readers an up-to-date insight on how panspermia might fit into the big picture. Audience Given the intrinsic interdisciplinary nature of the panspermia hypothesis the book will have a wide audience across various scientific disciplines covering astronomy, biology, physics and chemistry. Apart from scientists, the book will appeal to engineers who are involved in planning and realization of future space missions.

This book was released on 2010 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: The idea that comets may be connected with the origin of life on Earth was considered heresy a few decades ago, with scientists shying away from this possibility as if from a medieval superstition. However the case that comets may have contributed at least the complex organic building blocks of life has become very strong, and mechanisms have now been identified whereby comets may incubate and transfer microbial life from one cosmic habitat to another in the Galaxy. The latter process cometary panspermia was pioneered by the late Sir Fred Hoyle and one of the present authors in the early 1980's. A theory that was once controversial is slowly gaining scientific respectability and support.The recent surge of interest in astrobiology has led to a spate of books in astrobiology -- combining astronomy and biology -- but in most of these, cometary panspermia is dealt with only cursorily. The present book sets out the case for cometary panspermia in a cogent way, combining evidence from space science, celestial mechanics, geology and microbiology. It should be an essential part of any university course on astrobiology, and also serve as a reference textbook for researchers in the field.

Book excerpt: TECHNOSIGNATURES FOR DETECTING INTELLIGENT LIFE IN OUR UNIVERSE This book shows the current state of the research in the field of technosignatures, presenting novel ideas from economics, forecasting, and data sciences, making it an ideal research compendium for scientists. The book summarizes the multiple interdisciplinary efforts that have contributed to the field of technosignatures. The technosignatures represent any signals that can be collected from the Universe, such as radio wavelengths, optical signals, and many more, that can be potential candidates as signals emitted intentionally from another part of the Universe that is not Earth. It shows how current advances in science, technology, and social sciences can support this effort and can be used as both a resource for the scientists in the field and as a reference for the public at large interested in the topic. It includes novel research work from economics, forecasting, and data sciences fields, as well as a deeper understanding of the role mass media and popular fiction has played in the evolution of this field. Audience The book will interest both natural scientists (astronomers and astrophysicists) and social scientists (economists), as well as the new emerging data scientists. Amateur astronomers will be attracted to the book as well.

Available in PDF, EPUB and Kindle. Book excerpt: This book looks at the persistence of life and how difficult it would be to annihilate life, especially a species as successful as humanity. The idea that life in general is fragile is challenged by the hardiness of microbes, which shows that astrobiology on exoplanets and other satellites must be robust and plentiful. Microbes have adapted to virtually every niche on the planet, from the deep, hot biosphere, to the frigid heights of the upper troposphere. Life, it seems, is almost indestructible. The chapters in this work examine the various scenarios that might lead to the extermination of life, and why they will almost always fail. Life's highly adaptive nature ensures that it will cling on no matter how difficult the circumstances. Scientists are increasingly probing and questioning life's true limits in, on and above the Earth, and how these limits could be pushed elsewhere in the universe. This investigation puts life in its true astronomical context, with the reader taken on a journey to illustrate life's potential and perseverance.

Available in PDF, EPUB and Kindle. Book excerpt: Rating: Excellent Reviewed by: Eric Jones It’s become rather fashionable in literature today for authors to put a new spin on the link between science and religion. As both philosophies continue to collide, spin, and evolve into one another readers have been treated to books like Genome Scientist Francis Collins’ “Language of God”, which presents religion from a scientific point of view, along with rebuttals like Richard Dawkins’ “The God Delusion”, but nobody makes an argument quite like Ahamed V.P. Kutty. In his similar exploration of these worlds, Kutty presents evidence in the face of a religious question often overlooked among Christians, Muslims, and Jewish practitioners. The question is simple: If incest is a sin, and Adam and Eve were the first humans created by God to conceive and populate the earth, then wouldn’t their offspring be forced to mate with one another in order to achieve such ends? In essence, has God, or the creators of the Bible and Qur’an, created a situation where humanity must sin to survive? The answer, as always, is not as simple as the question. As the title might have given away, this is a book of scientific research which takes the writings of biblical scripture into account in order to achieve an answer. As such, it assumes that the reader is also religious. But not blindly so, as an overwhelming amount of scientists are turning to religion to solve the questions that they themselves cannot, it is no small readership that Kutty addresses. And his writing is cleverly detailed from both points of view so that ministers of faith will find it just as interesting as those of science. Answering the proposed thesis leads the reader on a journey through many questions that befuddle even the most devout religious followers. Where is the biblical Garden of Eden? How does religion account for the theory of evolution? Who are the real Adam and Eve? Is the Bible meant to be taken literally, or as hyperbole? Walking a middle path between the radical views of both science and religion is bound to offend fringe readers, but I think the majority of us tend to hold a similar middle ground. And for us, Kutty lays an overwhelming amount of evidence at our feet, which take all widely accepted viewpoints regarding the nature of evolution, the Garden of Eden, and the many different versions of Adam and Eve, into account. Often Kutty excludes the verbalized opinion that is so prominent in the works of his contemporaries, allowing the reader to connect the dots for themselves having looked over each textual exhibit. This layout is also helpful for quick reading, reference, and maintaining interest of laymen, like me, since all of these points are categorically organized and labeled. Each chapter begins with a clearly stated paragraph that elaborates on its title, and is often followed by the listing of evidence which lead the reader to the drawn conclusion. What Kutty is able to do, using this method, is clearly present his case without reducing anything to simple conjecture. Although this method does have a few minor holes since using evidence connecting so many different sources is sometimes thin. For instance, the use of a theory in general relativity to explain how angels of heaven might be able to travel through wormholes to get between Heaven and Earth is, according to Kutty himself, “not readily acceptable but feasible”. In other words, there is only so much that science can explain. However, the research regarding DNA histories which trace ancestry back to an original Adam and Eve, (though admittedly not the Bible’s Adam and Eve) is extremely positive. These many cases often provide a jumping point for those who wish to examine the issues more closely through the inclusion, at the end of each chapter, of a detailed bibliography. “Adam’s Gene and the Mitochondrial Eve” is brilliant. It constructs a dazzling house of carefully implemente

Book excerpt: In Skeptical, author Bob Moores describes his atheistic/humanistic philosophy and traces its roots back to early childhood epiphanies where he first began to question certain axiological teachings. He argues against creationism and religious fundamentalism and defends scientific naturalism, critical thinking, and a rational approach to understanding the world. Moores attempts to show readers how recent scientific discoveries, especially in biology, are more exciting and uplifting than any form of biblical mythology. Using lay terms, he explains the significance of DNA and why a scientific theory is more than just a guess. He argues that modern humanistic values are superior in many ways to those venerated in ancient texts, and he shares his belief that humans are both the greatest threat and greatest hope for the preservation of life on Earth. Moores hopes that Skeptical will challenge readers to consider views and information that may conflict with their comfort zones, allowing them to broaden their perspectives. He argues that if we are too protective of our own paradigms, if we stubbornly believe that our way is the only way, then the tribes of earth will never come together to solve the most urgent need of all – our continued existence.

Book excerpt: Habitability of the Universe before Earth: Astrobiology: Exploring Life on Earth and Beyond (series) examines the times and places—before life existed on Earth—that might have provided suitable environments for life to occur, addressing the question: Is life on Earth de novo, or derived from previous life? The universe changed considerably during the vast epoch between the Big Bang 13.8 billion years ago and the first evidence of life on Earth 4.3 billion years ago, providing significant time and space to contemplate where, when and under what circumstances life might have arisen. No other book covers this cosmic time period from the point of view of its potential for life. The series covers a broad range of topics encompassing laboratory and field research into the origins and evolution of life on Earth, life in extreme environments and the search for habitable environments in our solar system and beyond, including exoplanets, exomoons and astronomical biosignatures. Provides multiple hypotheses on the origin of life and distribution of living organisms in space Explores the diversity of physical environments that may support the origin and evolution of life Integrates contemporary views in biology and cosmology, and provides reasons that life is far more mobile in space than most people expect Includes access to a companion web site featuring supplementary information such as animated computer simulations

Available in PDF, EPUB and Kindle. Book excerpt: A rigorous and scientific analysis of the myriad possibilities of life beyond our planet. “Are we alone in the universe?” This tantalizing question has captivated humanity over millennia, but seldom has it been approached rigorously. Today the search for signatures of extraterrestrial life and intelligence has become a rapidly advancing scientific endeavor. Missions to Mars, Europa, and Titan seek evidence of life. Laboratory experiments have made great strides in creating synthetic life, deepening our understanding of conditions that give rise to living entities. And on the horizon are sophisticated telescopes to detect and characterize exoplanets most likely to harbor life. Life in the Cosmos offers a thorough overview of the burgeoning field of astrobiology, including the salient methods and paradigms involved in the search for extraterrestrial life and intelligence. Manasvi Lingam and Abraham Loeb tackle three areas of interest in hunting for life “out there”: first, the pathways by which life originates and evolves; second, planetary and stellar factors that affect the habitability of worlds, with an eye on the biomarkers that may reveal the presence of microbial life; and finally, the detection of technological signals that could be indicative of intelligence. Drawing on empirical data from observations and experiments, as well as the latest theoretical and computational developments, the authors make a compelling scientific case for the search for life beyond what we can currently see. Meticulous and comprehensive, Life in the Cosmos is a master class from top researchers in astrobiology, suggesting that the answer to our age-old question is closer than ever before.
