Ultraviolet Astronomy and the Quest for the Origin of Life utilizes astronomical observations in the ultraviolet range to better understand the generation of complex, life-precursor molecules. The origin of RNA is still under debate but seems to be related to the generation of pools of complex organic molecules submitted to heavy cycles of solution in water and drying. This book investigates whether these cycles require a planetary surface or may occur in space by examining both the theoretical and observational aspects of the role of UV radiation in the origin of life. This book offers the latest advances in these studies for astronomers, astrobiologists and planetary scientists. Addresses both the theoretical and observational aspects of the role of Ultraviolet (UV) radiation in the origin of life Investigates requirements on planetary surfaces, in space, and the origin of RNA Builds on the use of ultraviolet observations related to planetary system formation, the evolution of young planetary disks, and the interaction of stars with planetary atmospheres

In the history of science the opening up of a new observational or experimental window is always followed by an increase in knowledge of the subject concerned. This is also the case with the subject of this book, ultraviolet radiation (hereafter UV). In principle, the ultraviolet range might be just one more of these windows, of no particular importance. However, the energy per UV photon provides the main peculiarity, its magnitude being great enough to produce important ch- ical reactions in the atmospheres of planets and satellites, thereby a?ecting the transmission of this radiation to the ground. The Sun is the main natural source of UV radiation in the Solar System and our planet is the body where its in?uences can be best tested and the only one where its relation with life can be studied. However, the terrestrial atmosphere blocksmostofthephotonsinthiselectromagneticrangeandastronomershavehad to develop various techniques (balloons, planes and rockets) to cross this barrier and access the information. These tools have been used in parallel to investigate the physical properties of the terrestrial atmosphere and the interaction of its constituents with light. This book will addresses most of these topics.

These are exciting times for exobiology. The ubiquity of organic molecules in interstellar clouds, comets and asteroids strongly supports a cosmic perspective on the origin of life. Data from both ground-based telescopes and the recently launched Infrared Space Observatory are providing new insight into the complexity of carbon-based chemistry beyond the Earth. Meteorites give us solid evidence for extraterrestrial amino acids, and putative fossil evidence for life in a 3.6 billion-year-old Martian meteorite hints that life in our system might not be the sole prerogative of the Earth. Giant planets have now been discovered orbiting other stars, and although such planets seem unlikely to be habitable themselves, their existence strongly suggests what many astronomers have long believed - that planetary systems are commonplace. All these topics are reviewed in this volume by active researchers. The level is appropriate for graduate students in astronomy, biology, chemistry, earth sciences, physics, and related disciplines. It will also provide a valuable source of reference for active researchers in these fields.

Astronomers have recently discovered thousands of exotic planets that orbit stars throughout our Milky Way galaxy. With his characteristic wit and style, Donald Goldsmith shows how these observations have already broadened our planetary horizons, and tells us what may come next, including the ultimate discovery: life beyond our home planet.

Based on the author’s own work and results obtained by international teams he coordinated, this SpringerBrief offers a concise discussion of the origin and early evolution of atmospheres of terrestrial planets during the active phase of their host stars, as well as of the environmental conditions which are necessary in order for planets like the Earth to obtain N_2-rich atmospheres. Possible thermal and non-thermal atmospheric escape processes are discussed in a comparative way between the planets in the Solar System and exoplanets. Lastly, a hypothesis for how to test and study the discussed atmosphere evolution theories using future UV transit observations of terrestrial exoplanets within the orbits of dwarf stars is presented.

In 1997, the National Aeronautics and Space Administration (NASA) formed the National Astrobiology Institute to coordinate and fund research into the origins, distribution, and fate of life in the universe. A 2002 NRC study of that program, Life in the Universe: An Assessment of U.S. and International Programs in Astrobiology, raised a number of concerns about the Astrobiology program. In particular, it concluded that areas of astrophysics related to the astronomical environment in which life arose on earth were not well represented in the program. In response to that finding, the Space Studies Board requested the original study committee, the Committee on the Origins and Evolution of Life, to examine ways to augment and integrate astronomy and astrophysics into the Astrobiology program. This report presents the results of that study. It provides a review of the earlier report and related efforts, a detailed examination of the elements of the astrobiology program that would benefit from greater integration and augmentation of astronomy and astrophysics, and an assessment of ways to facilitate the integration of astronomy with other astrobiology disciplines.

This book presents an up-to-date collection of reviews and contributed articles in the field of ultraviolet astronomy. Its content has been mainly motivated by the recent access to the rest frame UV light of distant red galaxies, gained through large optical facilities. This driveway has derived in a renewed interest on the stars that presumably dominate or have important effects on the integrated UV properties of evolved systems of the nearby and faraway Universe. The topics included in this volume extend from the fresh spectroscopic analyses of high redshift early-type galaxies observed with the 8-10m class telescopes to the fundamental outcomes from various satellites, from the long-lived International Ultraviolet Explorer to current facilities, such as the Galaxy Evolution Explorer. This is one of the few volumes published in recent years devoted to UV astronomical research and the only one dedicated to the properties of evolved stellar populations at these wavelengths. This contemporary panorama will be an invaluable resource in the preparation of the next planned space missions, such as the World Space Observatory and the Ultraviolet Imaging Telescope.

With stunning regularity, the search for our cosmic roots has been yielding remarkable new discoveries about the universe and our place in it. In his compelling book, Origins: The Quest for Our Cosmic Roots, veteran science journalist Tom Yulsman chronicles the latest discoveries and describes in clear and engaging terms what they mean. From the interior of protons to the outer reaches of the universe, and from the control room of one of the world's most powerful particle accelerators to an observatory atop the tallest mountain in the Pacific basin, Yulsman takes readers on a fantastic voyage at the cutting edge of science. How could the universe have sprouted from absolute nothingness? What is the origin of galaxies? How do stars and planets form? And despite what now seem to be incredible odds, how did Earth come to be a rich oasis of biodiversity-one that has given rise to a species intelligent enough to ask these questions? In laying out the answers, Origins addresses some of the most profound issues humans have ever confronted.
