Abstract

Astrobiology is the multi-disciplinary field devoted to the investigation of the origin; physical, chemical and environmental limitations; and the distribution in space and time of life on Earth and in the Cosmos. Astrobiology seeks an answer to one of the most fundamental of all questions: - Is Life Restricted to Planet Earth or is Life a Cosmic Imperative? Understanding the characteristics, properties, habits and diversity of living organisms on Earth is crucial to determine where and how to search for evidence of life elsewhere.

Abstract

Due to its specific chemical and physical properties, water is essential for life on Earth. And it is assumed that this would be the case for extraterrestrial life as well. Therefore it is important to investigate where water can be found in the Universe. Although there are places that are completely dry, places where the last rainfall happened probably several 100 million years ago, surprisingly this substance is quite omnipresent. In the outer solar system the large satellites of Jupiter and Saturn are covered by a thick layer of ice that could be hiding a liquid ocean below. This of course brings up the question of whether the recently detected extrasolar planets could have some water on their surfaces and how we can detect this. Water molecules are also found in interstellar gas and dust clouds. This book begins with an introductory chapter reviewing the physical and chemical properties of water. Then it illuminates the apparent connection between water and life. This is followed by chapters dealing with our current knowledge of water in the solar system, followed by a discussion concerning the potential presence and possible detection of water on exoplanets. The signature of water in interstellar space and stars are reviewed before the origin of water in the Universe is finally discussed. The book ends with an appendix on detection methods, satellite missions and astrophysical concepts touched upon in the main parts of the book. The search for water in the Universe is related to the search for extraterrestrial life and is of fundamental importance for astrophysics, astrobiology and other related topics. This book therefore addresses students and researchers in these fields.

Abstract

Chaque enfant, chaque adulte est un vrai Jules Verne quand il s’agit de la conquête de l’espace. Les avions toujours plus performants, les hélicoptères, les drones nous font rêver. Et les satellites, donc, avec leurs promesses d’exploration des astres voisins ! Malgré les difficultés concrètes dues au manque de combustible fossile qui s’esquisse, le transport aérien reste une priorité. La mondialisation galopante impose des contacts humains réels entre pays différents, aux extrémités du monde. L’utilisation des satellites pour les télécommunications est devenue indispensable, par exemple pour le développement d’Internet ou pour les GPS. Les demandes de surveillances tous azimuts par les drones ou par les petits satellites se multiplient. Tout indique que l’utilisation de l’espace, l’un des grands thèmes de la technologie actuelle, le restera pour les années qui viennent. On trouvera dans ce livre l’exposé des multiples objectifs des recherches qui nous préparent le futur en matière de transport aérien et d’exploration de l’espace. Pour réussir les projets souvent aussi ambitieux que hardis, la recherche est sollicitée de façon majeure. Cette recherche, c’est dans une large mesure celle de nouveaux matériaux, métaux rares, composites ou matières plastiques de haute performance. Autant dire que cet ouvrage regorge d’exemples d’applications de cette vaste et féconde discipline qu’est la chimie, exposés par des professionnels spécialistes des laboratoires de recherche et des industries. L’aéronautique et l’espace jouent un rôle déterminant au niveau sociétal ; pour le premier en termes d’énergie, de sécurité ou de confort, pour le second dans le cadre de la quête perpétuelle de l’humanité des éléments fondamentaux pour la connaissance de l’Univers, de son évolution et des connaissances de l’origine de la vie.

Abstract

This pathbreaking book explores how life can begin, taking us from cosmic clouds of stardust, to volcanoes on Earth, to the modern chemistry laboratory. Seeking to understand life's connection to the stars, David Deamer introduces astrobiology, a new scientific discipline that studies the origin and evolution of life on Earth and relates it to the birth and death of stars, planet formation, interfaces between minerals, water, and atmosphere, and the physics and chemistry of carbon compounds. Deamer argues that life began as systems of molecules that assembled into membrane-bound packages. These in turn provided an essential compartment in which more complex molecules assumed new functions required for the origin of life and the beginning of evolution. Deamer takes us from the vivid and unpromising chaos of the Earth four billion years ago up to the present and his own laboratory, where he contemplates the prospects for generating synthetic life. Engaging and accessible, First Life describes the scientific story of astrobiology while presenting a fascinating hypothesis to explain the origin of life.
