Book Description
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.

Book Description
In Searching for Water in the Solar System, Thérèse Encrenaz takes the reader on a journey through the Universe in search of water. She begins by introducing the most well-known of molecule H2O, its physical and chemical characteristics and its cosmic Formation and abundance. She examines the methods by which the presence of water is detected, both within the solar system and beyond. One by one she visits a diversity of locations in the cosmos, from the nearest planets to the furthest galaxies, where water has been discovered. In the formation of the solar system, she explains how the water molecule played a major part, with the so-called ‘ice frontier’ determining the natures of the terrestrial and giant planets. The book explores the presence of water in the various bodies of the Solar System: in the giant planets, with their rings and systems of satellites, in comets, asteroids and in the terrestrial planets. By tracing the history of water in the atmospheres of Mars, Venus and the Earth, the author explains how small differences in temperatures, causing water to exist in different states on different planets – vapour on Venus, liquid on Earth and solid ice on Mars – have led to a great divergence in the evolutions of the three planets. The story of water on Mars, an aspect of great topical interest, offers an insight into the possibility (still only a theory) that there was once life on that planet. The book concludes by looking at the important role played by water in studies of habitable exoplanets.

Book Description
'Highly recommended' Financial Times Today we know of only a single planet that hosts life: the Earth. But across a Universe of at least 100 billion possibly habitable worlds, surely our planet isn't the only one which, like the porridge Goldilocks sought, is just right for life? Astrobiologists search the galaxy for conditions that are suitable for life to exist, focusing on similar worlds located at the perfect distance from their Sun, within the aptly named 'Goldilocks Zone'. Such a place might have liquid water on its surface, and may therefore support a thriving biosphere. What might life look like on other worlds? It is possible to make best-guesses using facts rooted in science, and by studying 'extremophiles' – organisms such as the near-indestructible water bears, which can survive in the harshest conditions that Earth, and even space, can offer. Goldilocks and the Water Bears is a tale of the origins and evolution of life, and the quest to find it on other planets, on moons, in other galaxies, and throughout the Universe.

Book Description
A major scientific revolution has begun, a new paradigm that rivals Darwin's theory in importance. At its heart is the discovery of the order that lies deep within the most complex of systems, from the origin of life, to the workings of giant corporations, to the rise and fall of great civilizations. And more than anyone else, this revolution is the work of one man, Stuart Kauffman, a MacArthur Fellow and visionary pioneer of the new science of complexity. Now, in At Home in the Universe, Kauffman brilliantly weaves together the excitement of intellectual discovery and a fertile mix of insights to give the general reader a fascinating look at this new science--and at the forces for order that lie at the edge of chaos. We all know of instances of spontaneous order in nature--an oil droplet in water forms a sphere, snowflakes have a six-fold symmetry. What we are only now discovering, Kauffman says, is that the range of spontaneous order is enormously greater than we had supposed. Indeed, self-organization is a great undiscovered principle of nature. But how does this spontaneous order arise? Kauffman contends that complexity itself triggers self-organization, or what he calls "order for free," that if enough different molecules pass a certain threshold of complexity, they begin to self-organize into a new entity--a living cell. Kauffman uses the analogy of a thousand buttons on a rug--join two buttons randomly with thread, then another two, and so on. At first, you have isolated pairs; later, small clusters; but suddenly at around the 500th repetition, a remarkable transformation occurs--much like the phase transition when water abruptly turns to ice--and the buttons link up in one giant network. Likewise, life may have originated when the mix of different molecules in the primordial soup passed a certain level of complexity and self-organized into living entities (if so, then life is not a highly improbable chance event, but almost inevitable). Kauffman uses the basic insight of "order for free" to illuminate a staggering range of phenomena. We see how a single-celled embryo can grow to a highly complex organism with over two hundred different cell types. We learn how the science of complexity extends Darwin's theory of evolution by natural selection: that self-organization, selection, and chance are the engines of the biosphere. And we gain insights into biotechnology, the stunning magic of the new frontier of genetic engineering--generating trillions of novel molecules to find new drugs, vaccines, enzymes, biosensors, and more. Indeed, Kauffman shows that ecosystems, economic systems, and even cultural systems may all evolve according to similar general laws, that tissues and terra cotta evolve in similar ways. And finally, there is a profoundly spiritual element to Kauffman's thought. If, as he argues, life were bound to arise, not as an incalculably improbable accident, but as an expected fulfillment of the natural order, then we truly are at home in the universe. Kauffman's earlier volume, The Origins of Order, written for specialists, received lavish praise. Stephen Jay Gould called it "a landmark and a classic." And Nobel Laureate Philip Anderson wrote that "there are few people in this world who ever ask the right questions of science, and they are the ones who affect its future most profoundly. Stuart Kauffman is one of these." In At Home in the Universe, this visionary thinker takes you along as he explores new insights into the nature of life.

Book Description
The story of the most abundant substance on Earth, from its origins in the birth of stars billions of years ago to its importance in the living world. Water is so ubiquitous in our lives that it is easy to take for granted. The average American uses ninety gallons of water a day; nearly every liquid we encounter is mostly water--milk, for example, is 87 percent water. Clouds and ice--water in other forms--affect our climate. Water is the most abundant substance on Earth, and the third-most abundant molecule in the universe. In this lavishly illustrated volume, science writer Jack Challoner tells the story of water, from its origins in the birth of stars to its importance in the living world. Water is perhaps the most studied compound in the universe--although mysteries about it remain--and Challoner describes how thinkers from ancient times have approached the subject. He offers a detailed and fascinating look at the structure and behavior of water molecules, explores the physics of water--explaining, among other things, why ice is slippery--and examines the chemistry of water. He investigates photosynthesis and water's role in evolutionary history, and discusses water and weather, reviewing topics that range from snowflake science to climate change. Finally, he considers the possibility of water beyond our own hydrosphere--on other planets, on the Moon, in interstellar space.

Book Description
"Water is the most every day of substances. It pours from our taps and falls from the sky. We drink it, wash with it, and couldn't live without it. Yet, on closer examination it is also a very strange substance (it is one of only a very small number of molecules which expand when cooled). Look closer again and water reveals itself as a key to a scientific story on the biggest of canvases. Water is crucial to our survival - life depends on it - but it was also fundamental in the origins of life on Earth. The millions of gallons of water which make up our rivers, lakes and oceans, originated in outer space. How it arrived here and how those molecules of water were formed, is a story which takes us back to the beginning of the universe. Indeed, we know more about the depths of space than we do about the furthest reaches of the oceans. Water has also shaped the world we live in. Whether it is by gently carving the Grand Canyon over millennia, or in shaping how civilisations were built; we have settled our cities along rivers and coasts. Scientific studies show how we feel calmer and more relaxed when next to water. We holiday by the seas and lakes. Yet one day soon wars may be fought over access to water. The Water Book will change the way you look at water. After reading it you will be able to hold a glass of water up to the light and see within it a strange molecule that connects you to the origins of life, the birth (and death) of the universe, and to everyone who ever lived."--From publisher.

Book Description
Inside the epic quest to find life on the water-rich moons at the outer reaches of the solar system Where is the best place to find life beyond Earth? We often look to Mars as the most promising site in our solar system, but recent scientific missions have revealed that some of the most habitable real estate may actually lie farther away. Beneath the frozen crusts of several of the small, ice-covered moons of Jupiter and Saturn lurk vast oceans that may have existed for as long as Earth, and together may contain more than fifty times its total volume of liquid water. Could there be organisms living in their depths? Alien Oceans reveals the science behind the thrilling quest to find out. Kevin Peter Hand is one of today's leading NASA scientists, and his pioneering research has taken him on expeditions around the world. In this captivating account of scientific discovery, he brings together insights from planetary science, biology, and the adventures of scientists like himself to explain how we know that oceans exist within moons of the outer solar system, like Europa, Titan, and Enceladus. He shows how the exploration of Earth's oceans is informing our understanding of the potential habitability of these icy moons, and draws lessons from what we have learned about the origins of life on our own planet to consider how life could arise on these distant worlds. Alien Oceans describes what lies ahead in our search for life in our solar system and beyond, setting the stage for the transformative discoveries that may await us.
