For many thousands of years, human beings have been asking themselves whether they are more frightened of being alone in the universe or of the thought that there is someone else out there. Over the past few decades, however, we have moved from imagination to action, exploring the cosmos using new techniques, often with surprising results. Numerous fascinating but little known facts have emerged – for example, that every year many rocks from Mars fall on the Earth, that one of our amino acids has been found in the coma of a comet, and that some of the known thousands of extrasolar planets are similar to our own. There are further exciting and important discoveries around the corner that will cast more light on the great enigma of how life started on Earth. In this intriguing book, one of the World’s leading researchers in astrophysics and space science examines fundamental questions concerning life on Earth and the rest of the cosmos in an accessible and stimulating way.

In the year 2015, 100 years after Fred Hoyle was born, the ideas relating to the cosmic origins of life are slowly gaining credence in scientific circles. Once regarded as outrageous heresy, evidence from a variety of disciplines — astronomy, geology, biology — is converging to support these once heretical ideas. This volume opens with recent review articles pointing incontrovertibly towards our cosmic heritage, followed by a collection of published articles tracing the development of the theory throughout the years. The discovery that microorganisms — bacteria and viruses — are incredibly resistant to the harshest conditions of space, along with the detection of an estimated 144 billion habitable planets around other star systems in our galaxy alone, makes it virtually impossible to maintain that life on one planet will not interact with life elsewhere. The emerging position is that life arose exceedingly rarely, possibly only once, in the history of the cosmos, but its subsequent spread was unstoppable. "Panspermiology" can no longer be described as an eccentric doctrine, but rather is the only doctrine supported by an overwhelming body of evidence. Fred Hoyle's work in this area may in the fullness of time come to be regarded as his most important scientific contribution.

Biological Effects And Physics Of Solar And Galactic Cosmic Radiation

Space missions subject human beings or any other target of a spacecraft to a radiation environment of an intensity and composition not available on earth. Whereas for missions in low earth orbit (LEO), such as those using the Space Shuttle or Space Station scenario, radiation exposure guidelines have been developed and have been adopted by spacefaring agencies, for exploratory class missions that will take the space travellers outside the protective confines of the geomagnetic field sufficient guidelines for radiation protection are still outstanding. For a piloted Mars mission, the whole concept of radiation protection needs to be reconsidered. Since there is an increasing interest of many nations and space agencies in establishing a lunar base and lor exploring Mars by manned missions, it is both, timely and important to develop appropriate risk estimates and radiation protection guidelines which will have an influence on the design and structure of space vehicles and habitation areas of the extraterrestrial settlements. This book is the result of a multidisciplinary effort to assess the state of art in our knowledge on the radiation situation during deep space missions and on the impact of this complex radiation environment on the space traveller. It comprises the lectures by the faculty members as well as short contributions by the students given at the NATO Advanced Study Institute "Biological Effects and Physics of Solar and Galactic Cosmic Radiation" held in Armacao de Pera, Portugal, 12-23 October, 1991.

A sequel to “The War of the Worlds”, “Star Begotten” concerns another suspected attack by the Martians, this time using cosmic rays to change human DNA. Joseph Davis is a writer of popular books who becomes obsessed with the rumours of invasion, so much so that he fears his wife, child, and even him might have already been affected by the cosmic rays. Contents include: “The Mind of Mr. Joseph Davis Is Greatly Troubled”, “Mr. Joseph Davis Learns about Cosmic Rays”, “Mr. Joseph Davis Wrestles with an Incredible Idea”, “Dr. Holdman Stedding Is Infected with the Idea”, “Professor Ernest Keppel Takes Up the Idea in His Own Peculiar Fashion”, et cetera. Herbert George Wells (1866 – 1946) was a prolific English writer who wrote in a variety of genres, including the novel, politics, history, and social commentary. Today, he is perhaps best remembered for his contributions to the science fiction genre thanks to such novels as “The Time Machine” (1895), “The Invisible Man” (1897), and “The War of the Worlds” (1898). Many vintage books such as this are becoming increasingly scarce and expensive. We are republishing this book now in an affordable, modern, high-quality edition complete with a specially commissioned new biography of the author. First published in 1937.

To many people, the main question about extraterrestrial life is whether it exists. But to the scientific community, that question has already been answered: it does, and within our solar system. The new science of astrobiology is already being practiced at NASA's Astrobiology Institute and the University of Washington's new Department of Astrobiology. Life Everywhere is the first book to lay out what the new science of astrobiology is all about. It asks the fascinating questions researchers in astrobiology are asking themselves: What is life? How does it originate? How often does life survive once it arises? How does evolution work? And what determines whether complex or intelligent life will emerge from more primitive forms? Informed by interviews with most of the top people in this nascent field, this book introduces readers to one of the most important scientific developments of the next century.

In this sweeping tour of the cosmos and our place within it, acclaimed science writer Jeff Kanipe shows the many ways we are connected to the vast universe we inhabit. Long before our ape-like ancestors dropped from the trees and began playing with fire, even before the Sun emerged from its chrysalis of dust and irradiated its brood of planets, numberless and nameless astronomical events affected Earth and its emerging life-forms. Our chemical make-up -- from the iron in our blood to the calcium in our bones -- derives from stars that lived and died hundreds of millions of years ago. Comets have showered organic molecules into our oceans, and asteroid impacts have wiped out predominant species that lived before. Tracing the whole natural history of how events in the near and far universe have influenced life on Earth today, and how they might influence life in the future, Kanipe, with unparalleled eloquence, explores a host of intriguing questions: How the Earth's orbit and inclination have triggered past ice ages; The role ancient supernovae may have played in mass extinctions and genetic changes; How a slight but persistent dip in solar output contributed to a multi-century cooling event called the "Little Ice Age"; The dangers posed by intense geomagnetic storms; How ancient asteroid impacts pressed Earth's evolutionary reset button and how astronomers are striving to make sure that it won't happen again; The widespread effects that our Sun's changing galactic environment has on life and climate. Kanipe also reflects upon the possible societal effects of alien contact, a type of cosmic intervention that some astronomers believe could happen within the next few decades. His elegant, jargon-free descriptions of the truly "big-picture view" of life on Earth will fascinate and inform everyone who has an interest in astronomy, the evolution of our planet, and the future of humankind.
