This book offers an overview of solar physics with a focus on solar activity, particularly the activity cycle. It is known that solar activity varies periodically, but there are also phases of intermittency, such as the Maunder minimum, during which solar activity is very low or high over several decades. The book provides a brief introduction to chaos theory and investigates solar activity in terms of its chaotic behavior. It also discusses how intermittent phases of solar activity have affected and can affect Earth's climate and long-term space weather, and reviews the underlying theories relating to the solar dynamo mechanism. Furthermore, each chapter includes references to scientific literature (review articles and papers) so that readers can delve deeper into the subjects covered. This richly illustrated book will appeal to a wide readership, and is also useful as a textbook for courses in solar physics and astrophysics.

The Mars Curiosity Rover is the most sophisticated mobile laboratory ever deployed on a planet. For over seven years, scores of investigators have planned its daily route and activities, poring over the overwhelming images and data and revising our understanding of planetary surfaces, geology, and potential habitability. This book takes readers right down to the surface of Mars, chronicling Curiosity's physical and scientific journey across the planet's Earth-like, yet strikingly alien vistas. Through dozens of images and descriptive accounts of the surface, you will gain a deeper knowledge of the Martian landscape, from the floor of Gale Crater up to the cliffs of Mount Sharp. Presented at the end of each chapter are the results and revelations from the science team spearheading the mission. Like any cross-country road trip, the rover has hit some unexpected hitches along the way. The book describes the obstacles faced by the rover and its scientists over the years and the difficult decisions and careful experimentation it took to solve them.

This book provides a systematic introduction to the observation and application of kinetic Alfven waves (KAWs) in various plasma environments, with a special focus on the solar-terrestrial coupling system. Alfven waves are low-frequency and long-wavelength fluctuations that pervade laboratory, space and cosmic plasmas. KAWs are dispersive Alfven waves with a short wavelength comparable to particle kinematic scales and hence can play important roles in the energization and transport of plasma particles, the formation of fine magneto-plasma structures, and the dissipation of turbulent Alfven waves. Since the 1990s, experimental studies on KAWs in laboratory and space plasmas have significantly advanced our understanding of KAWs, making them an increasingly interesting subject. Without a doubt, the solar-terrestrial coupling system provides us with a unique natural laboratory for the comprehensive study of KAWs. This book presents extensive observations of KAWs in solar and heliospheric plasmas, as well as numerous applications of KAWs in the solar-terrestrial coupling system, including solar atmosphere heating, solarwind turbulence, solar wind-magnetosphere interactions, and magnetosphere-ionosphere coupling. In addition, for the sake of consistency, the book includes the basic theories and physical properties of KAWs, as well as their experimental demonstrations in laboratory plasmas. In closing, it discusses possible applications of KAWs to other astrophysical plasmas. Accordingly, the book covers all the major aspects of KAWs in a coherent manner that will appeal to advanced graduate students and researchers whose work involves laboratory, space and astrophysical plasmas.

Lifting Titan's Veil is a revealing account of the second largest moon in our solar system. This world in orbit around Saturn is the only body in the solar system with an atmosphere strikingly similar to Earth's. Titan is like a giant frozen laboratory that may help scientists understand the first chemical steps towards the origin of life. Beginning with its discovery in 1655, the authors describe our current knowledge of Titan, including observations made before the space age, results from the Voyager missions of the 1980s, and recent revelations from the world's most advanced telescopes. In Lifting Titan's Veil, Ralph Lorenz includes his personal experiences in preparing for the Cassini mission, which will reach Saturn in 2004 and release the Huygens probe into Titan's atmosphere in 2005. A splendid introduction to Titan, this book will appeal to anyone interested in astronomical discovery and space exploration. Ralph Lorenz trained as an engineer and worked for the European Space Agency at the very beginning of the Huygens project. Since obtaining a PhD at the University of Kent, England, he has worked as a planetary scientist at the University of Arizona, Tucson. His research interests focus on Titan, but also include climatology, radar, impact dynamics and spacecraft and instrumentation design. He has been involved in NASA's largest planetary mission (Cassini) and its smallest (the DS-2 Mars Microprobes). Jacqueline Mitton obtained a Ph.D in astrophysics from the University of Cambridge, and is now a full-time writer and media consultant specializing in astronomy. She has served as Press Officer for the Royal Astonomical Society since 1989, and was Editor of the Journal of the British Astronomical Association 1989-1993. She has written or co-authored sixteen published astronomy books, the most recent, The Cambridge Dictionary of Astronomy (2001).

Astrobiology not only investigates how early life took hold of our planet but also life on other planets - both in our Solar System and beyond - and their potential for habitability. The book take readers from the scars on planetary surfaces made by space rocks to the history of the Solar System narrated by those space rocks as well as exoplanets in other planetary systems. But the true question is how life arose here or elsewhere. Modern comparative genomics has revealed that Darwin was correct; a set of highly conserved genes and cellular functions indicate that all life is related by common ancestry. The Last Universal Common Ancestor or LUCA sits at the base of the Tree of Life. However, once that life took hold, it started to diversify and form complex microbial communities that are known as microbial mats and stromatolites. Due to their long evolutionary history and abundance on modern Earth, research on the biological, chemical and geological processes of stromatolite formation has provided important insights into the field of astrobiology. Many of these microbialite-containing ecosystems have been used as models for astrobiology, and NASA mission analogs including Shark Bay, Pavilion and Kelly Lakes. Modern microbialites represent natural laboratories to study primordial ecosystems and provide proxies for how life could evolve on other planets. However, few viral metagenomic studies (i.e., viromes) have been conducted in microbialites, which are not only an important part of the community but also mirror its biodiversity. This book focuses on particularly interesting sites such as Andean lake microbialites, a proxy of early life since they are characterized by very high UV light, while Alchichica and Bacalar lakes are characterized by high-salt and oligotrophic waters that nurture stromatolites. However, it is only the oasis of Cuatro Cienegas Basin in Mexico that stored past life in its marine sediments of the Sierra de San Marcos. This particular Sierra has a magmatic pouch that moves the deep aquifer to the surface in a cycle of sun drenched life and back to the depths of the magmatic life in an ancient cycle that now is broken by the overexploitation of the surface water as well as the deep aquifer in order to irrigate alfalfa in the desert. The anthropocene, the era of human folly, is killing this unique time machine and with it the memory of the planet.

This book is devoted to the most relevant issues in crystal chemistry and mineral typomorphism; the structure, physico-chemical and technological properties of minerals; and the computational modeling of mineral structure and properties. Considerable attention is paid to the latest advances in and applications of physical methods of investigation for mineral structure and composition, in particular, X-Ray diffraction, spectroscopic (optical, vibrational, ESR, Moessbauer, etc.) and microscopic (SEM, TEM, AFM, etc.) studies, as well as chemical and isotopic analysis methods. The current research trends in space and planetary mineralogy (meteorites, regolites, tektites) are also discussed. Though specifically intended for the specialist earth and planetary science readership, the book will be of interest to a broad range of scientists. It gathers the proceedings of the Tenth All-Russian Youth Scientific Conference "Minerals: structure, properties, methods of investigation." Jointly organized by the Institute of Geology and Geochemistry, the Institute of Mineralogy (Urals Branch of the Russian Academy of Sciences) and Ural Federal University, the event was held in Ekaterinburg, Russia, on May 27-June 1, 2019.

Exactly what is beyond Pluto? Why, in the last ten years, has the Solar System more than doubled in size? For the first time, in almost two centuries, an entirely new population of planetary objects has been found that may well explain these two questions. This newly discovered realm of minor planets, now known as the "Kuiper Belt," has reconceptualized our understanding of how the Solar System was formed and has finally given ontological explanations for the enigmatic outer planet Pluto. Beyond Pluto is the fascinating story of how a group of theoretical physicists decided that there must be a population of unknown bodies beyond Pluto and how a small band of astronomers set out to find them. Acclaimed scientist John K. Davies recounts how they predicted the existence of these planetary bodies, how they were eventually discovered, and how Pluto was named. In addition, Davies provides biographies of the astronomers who discovered these new worlds and information on the telescopes they used. John K. Davies is a support scientist for the UK Infrared Telescope (UKIRT) atop the dormant volcano Mauna Kea in Hawaii. He holds PhDs in chemistry and astronomy, discovered six comets while teaching at Leicester University in the UK, and was a member of the ISO-CAM team at the Royal Observatory in Edinburgh, Scotland. He has contributed to magazines such as Astronomy, New Scientist, Sky & Telescope, and Space. In 2000, a small main asteroid belt was named Johndavies in recognition of his numerous contributions to astronomy.

Julius Schmidt was one of the finest astronomical observers of his time, and his detailed map of the Moon surpassed anything that had come before. Today, the German astronomer and geophysicist has remained a largely neglected figure, despite being one of the most important players in the history of lunar studies. This book at last makes accessible Schmidt's highly regarded German work, Der Mond. Considered an astronomical classic of the nineteenth century, Der Mond remained without a proper English counterpart for the last century and a half, until now. The author's faithful English translation provides readers with much-needed access into Schmidt's original publication, with the aim of showing the community just how vital his work and legacy have been in the international field of selenography.

Based on 3D smoothed particle hydrodynamics simulations performed with unprecedented high resolution, this book examines the giant impacts that dominate many planets' late accretion and evolution. The numerical methods developed are now publicly available, greatly facilitating future studies of planetary impacts in our solar system and exoplanetary systems. The book focuses on four main topics: (1) The development of new methods to construct initial conditions as well as a hydrodynamical simulation code to evolve them, using 1000 times more simulation particles than the previous standard. (2) The numerical convergence of giant impact simulations -- standard-resolution simulations fail to converge on even bulk properties like the post-impact rotation period. (3) The collision thought to have knocked over the planet Uranus causing it to spin on its side. (4) The erosion of atmospheres by giant impacts onto terrestrial planets, and the first full 3D simulations of collisions in this regime.

This volume presents a full mathematical exposition of the growing field of coronal seismology which will prove invaluable for graduate students and researchers alike. Roberts' detailed and original research draws upon the principles of fluid mechanics and electromagnetism, as well as observations from the TRACE and SDO spacecraft and key results in solar wave theory. The unique challenges posed by the extreme conditions of the Sun's atmosphere, which often frustrate attempts to develop a comprehensive theory, are tackled with rigour and precision; complex models of sunspots, coronal loops and prominences are presented, based on a magnetohydrodynamic (MHD) view of the solar atmosphere, and making use of Faraday's concept of magnetic flux tubes to analyse oscillatory phenomena. The rapid rate of progress in coronal seismology makes this essential reading for those hoping to gain a deeper understanding of the field.

Here is an informative, up-to-date and well-illustrated guide to planetary observations for amateurs. After chapters on the solar system and the celestial sphere, the text explains how to choose, test and use a telescope with various accessories and how to make observations and record results. For each planet and the asteroids, Price gives details of observational techniques, together with suggestions for how to make contributions of sound astronomical value. From a general description and detailed observational history of each planet, readers learn how to anticipate what they should see and assess their own observations. New to this edition is a chapter on planetary photography that includes the revolutionary use of videography, charge coupled devices and video-assisted drawing. Another new feature is a section on the Kuiper Belt and Oort Cloud. Other chapters on making maps and planispheres and on photoelectric photometry round out the book's up-to-date treatment, making this indispensable reading for both casual and serious observer alike.

This didactic book uses a data-driven approach to connect measurements made by plasma instruments to the real world. This approach makes full use of the instruments' capability and examines the data at the most detailed level an experiment can provide. Students using this approach will learn what instruments can measure, and working with real-world data will pave their way to models consistent with these observations. While conceived as a teaching tool, the book contains a considerable amount of new information. It emphasizes recent results, such as particle measurements made from the Cluster ion experiment, explores the consequences of new discoveries, and evaluates new trends or techniques in the field. At the same time, the author ensures that the physical concepts used to interpret the data are general and widely applicable. The topics included help readers understand basic problems fundamental to space plasma physics. Some are appearing for the first time in a space physics textbook. Others present different perspectives and interpretations of old problems and models that were previously considered incontestable. This book is essential reading for graduate students in space plasma physics, and a useful reference for the broader astrophysics community.

This book describes numerical simulations of collisions between asteroids, based on a unique numerical code developed by the author. The code accurately solves the elastic dynamic equations and describes the effects of fracture and friction, which makes it possible to investigate the shapes of impact outcomes produced by asteroid collisions and subsequent gravitational accumulation of fragments. The author parallelizes the code with high parallelization efficiency; accordingly, it can be used to conduct high-resolution simulations with the aid of supercomputers and clarify the shapes of small remnants produced through the catastrophic destruction of asteroids. The author demonstrates that flat asteroids can only be produced by impacts involving objects with similar mass and low velocity, which suggests that the flat asteroids in our solar system were created in the planet formation era and have kept their shapes until today. The author also shows that asteroid collisions under certain conditions can produce the extremely elongated shape of an interstellar minor body, 1I/'Oumuamua. In brief, the book offers a comprehensive investigation of asteroid impacts and shapes, making it a uniquely valuable resource.

This book investigates the mineralogy and shock effects of Yanzhuang chondrite, using modern micro-mineralogical experimental techniques, including SEM, TEM, EPMA, Raman microprobe spectroscopy, instrumental neutron activation analysis, X-ray micro-diffraction analysis, micro-PIXE analysis and laser ablation ICP-MS. The micro-structural and micro-morphological characteristics as well as chemical composition of minerals were studied in details. Based on the studies in the shock effects of rocks and minerals, and the detailed study in the shock-produced melt, the book concludes that Yanzhuang chondrite is the most heavily shocked ordinary H group chondrite ever found and that it contains the most abundant shock induced melt among all known shock-melt-bearing chondritic meteorites.

From the Earth's atmosphere to the edges of our Universe, the presence of dust is ubiquitous. One of the main challenges in studying dust in these various environments is thus to harmonize the diverse research techniques and results, including in-situ measurement, remote observation, laboratory experiments and modelling, and analysis of returned samples. For the first time in over a decade, this volume accomplishes exactly that, providing an overarching picture of the current state of dust science and research. Where possible, the papers in this volume emphasize the interconnections, similarities, and differences in the field, synthesizing results from several techniques into one cohesive view. Importantly, astrobiological connections have now been considered. The dust hazard, future technology and research, and space mission requirements and scenarios are also addressed. The outcome of this endeavor is an interdisciplinary compendium with a unified perspective on cosmic dust science. Originally published in Space Science Reviews in the Topical Collection "Cosmic Dust from the Laboratory to the Stars"

This book is an original study aimed at understanding how vacuum magnetic fields change with time. Specifically, it describes the waves that radiate from a sphere when the electric current on its surface is turned on or off, either suddenly, gradually, or periodically. Numerical simulations are an invaluable source of information about this and related subjects, but they are often more difficult to interpret than exact, closed-form solutions that can easily be applied to a variety of situations. Thus, the objective here is to obtain an exact solution of Maxwell's equations in closed form-something simple, yet rigorous, which can be used as a model for understanding transient magnetic fields in more complicated situations. The work therefore stands as a self-contained solution of Maxwell's equations for an electric current wrapped around the surface of a sphere. This study assumes a strong background in electromagnetism or a related research area. Online animations are available for each figure to better illustrate the motions of magnetic field lines.

David Levy brings these "ghostly apparitions" to life. With fascinating scenarios both real and imagined, he shows how comets have wreaked their special havoc on Earth and other planets. Beginning with ground zero as comets take form, we track the paths their icy, rocky masses take around our universe and investigate the enormous potential that future comets have to directly affect the way we live on this planet and what we might find as we travel to other planets.

In this extraordinary volume, David Levy shines his expert light on a subject that has long captivated our imaginations and fears, and demonstrates the need for our continued and rapt attention.

With the discovery of planets beyond our solar system 25 years ago, exoplanet research has expanded dramatically, with new state-of-the-art ground-based and space-based missions dedicated to their discovery and characterisation.

This Handbook ties all these avenues of research together across a broad range of exoplanet science. Planet formation, exoplanet interiors and atmospheres, and habitability are discussed, providing in-depth coverage of our knowledge to date. Comprehensively updated from the first edition, it includes instrumental and observational developments, in-depth treatment of the new Kepler mission results and hot Jupiter atmospheric studies, and major updates on models of exoplanet formation. With extensive references to the research literature and appendices covering all individual exoplanet discoveries, it is a valuable reference to this exciting field for both incoming and established researchers.

This SpringerBrief explores the technological, economic, physiological, and psychological comparisons between a journey to the Moon versus a journey to Mars, taking into consideration the national and international perspectives at play. The author spent over six years interviewing leading space experts from around the world to learn why lunar habitats and the creation of a permanent presence on the Moon are an essential next step to human exploration and settlement in space. Practical reasons related to energy, telecommunications and networking, robotic systems, medical and scientific research, material processing, and more show why it must be the Moon First and Mars Second. These findings and recommendations have been adopted by current NASA Administrator Jim Bridenstine, as well as the current U. S. president. The research in this text reflects the author's experiences working internally within NASA Headquarters, the FAA Commercial Spaceflight Office, as well as the International Space University. It is partially based on Reneau's award-winning Harvard thesis in conjunction with her Master's in International Relations.

The Venus Express spacecraft, which was launched in November 2005 and ceased activity in December 2014, has brought about a new wealth of data on Venus's atmosphere, surface, and space environment. Following the completion of this landmark mission, an overview of the current state of scientific understanding of Venus has been assembled into a single collection. The ten papers in this book, written by an international team of specialists, are the products of this effort. They review our knowledge of Venus's interior structure, surface composition, and atmosphere in terms of thermal structure, dynamics, composition, chemistry, clouds, aeronomy, and interaction with the solar wind. Additionally, they identify the questions and measurements that remain open for study in ongoing and future research and exploration efforts. The resulting volume is primarily intended for students and researchers of planetary science. This book is a follow-up to the pioneering book Venus, published in 1983, and its successor volume Venus II, published in 1997, stood at their respective times as the most authoritative single-volume works available on the planet. Originally published in Space Science Reviews in the Topical Collection "Venus III"

This book presents two important new findings. First, it demonstrates from first principles that turbulent heating offers an explanation for the non-adiabatic decay of proton temperature in solar wind. Until now, this was only proved with reduced or phenomenological models. Second, the book demonstrates that the two types of anisotropy of turbulent fluctuations that are observed in solar wind at 1AU originate not only from two distinct classes of conditions near the Sun but also from the imbalance in Alfven wave populations. These anisotropies do not affect the overall turbulent heating if we take into account the relation observed in solar wind between anisotropy and Alfven wave imbalance. In terms of the methods used to obtain these achievements, the author shows the need to find a very delicate balance between turbulent decay and expansion losses, so as to directly solve the magnetohydrodynamic equations, including the wind expansion effects.

This book serves as both a primer to astronomical polarimetry and an authoritative overview of its application to various types of astronomical objects from AGN, compact stars, binary systems, stars across the HR diagram, transients, the interstellar medium and solar system bodies. It starts with an historical perspective, a discussion of polarimetric theory, instrumentation and techniques in wave bands from the near infrared to gamma rays. The book presents the state of the art in astronomical polarimetry. It is motivated by the new X-ray polarimeters due to be launched in the next four years and improved optical polarimeters on large telescopes requiring a new analysis of polarimetric theory, methodology and results.This book will be suitable as advanced undergraduate companion text, a primer for graduate students and all researchers with an interest in astronomical polarimetry.

This book follows the development of research on the origin of the Moon from the late 18th century to the present. By gathering together the major texts, papers, and events of the time, it provides a thorough chronicle of the paradigmatic shift in planetary science that arose from the notion that the Earth-Moon system was formed from two colliding planetary bodies. The book covers pre-Apollo ideas, the conceptual evolution during and subsequent to the Apollo explorations of the Moon, and the development of the Earth-Moon system consensus. A plethora of excerpts from key publications are included to demonstrate the shift in scientific focus over the centuries. Through its comprehensive review of lunar science research and literature, this book shows how new technologies and discoveries catalyzed the community and revolutionized our understanding of the Moon's formation.
