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.

How did science rise up to so dramatically change our world, and where will it take us in the future? This book gives a unique and broad overview. A brief history reveals the major phases and turning points in the rise of science from the earliest civilizations to the present: How was science ‘discovered’? Why did it disappear a few times? When did it become ‘modern’? A critical assessment examines how science actually ‘happens’: the triumphs, the struggles, the mistakes and the luck. Science today is endlessly fascinating, and this book explores the current exponential growth, curiosity-driven vs. goal-oriented research, big and small science, the support of science, the relation of science to society, philosophy and religion, and the benefits and dangers of science. Finally a glimpse into the future: Will the current pace of science continue? Will we ever go backwards (again)? What remains to be discovered? Can science ever be complete? What can we imagine for the distant future? This book will be of wide interest to the general reader as well as to students and working scientists. This book provides a fresh, unique and insightful coverage of the processes of science, its impact on society and our understanding of the world, based on the author’s experience gained from a lifetime in science. Ron Ekers, FRS, CSIRO Fellow, CSIRO Astronomy & Space Science, former President of the International Astronomical Union Peter Shaver's comprehensive and lively survey deserves a wide readership. Scientific discoveries are part of our global culture and heritage, and they underpin our lives. It's fascinating to learn how they were made, and how they fit into the grand scheme. This book isn't just for scientists - it's written for all of us. Martin Rees, FRS, Astronomer Royal, former President of the Royal Society and former Master of Trinity College, Cambridge This book offers a wonderfully concise and accessible insight into science – its history, breadth and future prospects. Peter Shaver gives a feeling for what it actually means to be a practicing scientist.

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. Contents:Recent ReviewsPapers from 2000–2014Papers from 1990–2000Papers from 1980–1990Papers from 1970–1980Prospects for the Future Readership: University students, researchers and historian of science interested in astrobiology or the work of Sir Fred Hoyle.

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.
