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.

The return of Halley's Cornet in 1986 has generated much ex citement in the scientific community with preparations already afoot for an International Cornet Watch and a cornet launch by the European Space Community, the Japanese and Soviet Space Scientists. The meet ing held at the University of Maryland in October 1980 was primarily stimulated by the preparations for further study of this cornet and by one of the most important unanswered questions related to comets, name ly, whether they may have made a eontribution to the origin of life on earth. Our un"derstanding of the role of comets in the origin of life must necessarily come from our studies of the astronomy and the chem istry of comets. Some clues to the processes which led to the for mation of organic molecules and eventually to the appearance of life have come from these studies of comets, perhaps the most ancient of all objects in our solar system. Whether there is, however, a biology of comets still remains to be seen, although some claims have been made that perhaps comets might themselves provide an environment for even the beginnings of life. Scientists with the latest available information on comets and differing opinions as to the role of comets in the origin of life attended this symposium. The formal papers presented are now being made available to the students of chemical evolution within the pages of this volume.

Nine years after the publication of Comets and the Origin and Evolution of Life, one of the pioneering books in Astrobiology, this second edition revisits the role comets may have played in the origins and evolution of life. Recent analyses of Antarctic micrometeorites and ancient rocks in Australia and South Africa, the continuing progress in discovering complex organic macromolecules in comets, protostars and interstellar clouds, new insights into organic synthesis in comets, and numerical simulations of comet impacts on the Earth and other members of the solar system yield a spectacular wealth of new results. This second edition is thus actually a new book. As the first edition it is intended as a comprehensive review of current research, accessible to graduate students and others new to the field. Each chapter was prepared by experts to give an overview of an aspect of the field, and carefully revised by the editors for uniformity in style and presentation.

Leading researchers in the area of the origin, evolution and distribution of life in the universe contributed to Exobiology: Matter, Energy, and Information in the Origin and Evolution of Life in the Universe. This volume provides a review of this interdisciplinary field. In 50 chapters many aspects that contribute to exobiology are reviewed by 90 authors. These include: historical perspective of biological evolution; cultural aspects of exobiology, cosmic, chemical and biological evolution, molecular biology, geochronology, biogeochemistry, biogeology, and planetology. Some of the current missions are discussed. Other subjects in the frontier of exobiology are reviewed, such as the search for planets outside the solar system, and the possible manifestation of intelligence in those new potential environments. The SETI research effort is well represented in this general overview of exobiology. This book is the proceedings of the Fifth Trieste Conference on Chemical Evolution that took place in September 1997. The volume is dedicated to the memory of Nobel Laureate Abdus Salam who suggested the initiation of the Trieste conferences on chemical evolution and the origin of life. Audience: Graduate students and researchers in the many areas of basic, earth, and life sciences that contribute to the study of chemical evolution and the origin, evolution and distribution of life in the universe.

Comets, those icy wanderers of our solar system, are the focus of ""Comet Origins,"" which explores their formation, behavior, and significance in the cosmic narrative. This book delves into the mysteries surrounding these celestial objects, shedding light on their composition and their role in the early solar system. Interestingly, comets are not static remnants but active participants in the solar system's evolution; for instance, the book highlights how gravitational forces from giant planets and solar radiation constantly shape them. The book examines the formation and evolution of comets within the protoplanetary disk and analyzes the dynamics of cometary orbits. It emphasizes the importance of understanding comets for insights into the delivery of water and organic molecules to early Earth. Using spectroscopic data from telescopes and measurements from space missions, the book supports its arguments by integrating observational data with theoretical models. Structured into three sections, ""Comet Origins"" first examines comet formation, then explores their composition and finally discusses their orbital dynamics. This approach offers a holistic understanding of these icy bodies, making it a valuable resource for students, amateur astronomers, and anyone fascinated by planetary science and astrophysics. Moreover, understanding the trajectory of comets also helps in strategies for planetary defense.

Each year brings to light new scientific discoveries that have the power to either test our faith or strengthen it--most recently the news that scientists have created artificial life forms in the laboratory. If humans can create life, what does that mean for the creation story found in Scripture? Biochemist and Christian apologist Fazale Rana, for one, isn't worried. In Creating Life in the Lab, he details the fascinating quest for synthetic life and argues convincingly that when scientists succeed in creating life in the lab, they will unwittingly undermine the evolutionary explanation for the origin of life, demonstrating instead that undirected chemical processes cannot produce a living entity.
