Solsystemet: solen og planeterne

Die Autoren Claus Grupen und Marcus Niechciol geben in diesem essential einen Ausblick auf die Chancen, der durch Uberbevolkerung und Klimaveranderung belasteten Erde zu entkommen. Der Mars als nachstliegender Planet ist ein naturlicher Kandidat fur eine Besiedelung durch den Menschen. Aber der Mars ist od und leer, ohne rechte Luft zum Atmen. Dazu kommt eine ungemutlich hohe Strahlenbelastung. All das fuhrt zu groen Herausforderungen fur zukunftige Marsbewohner. Oder ist der Mars doch kein so gutes Ziel?

A tour of the Solar System's tallest, hottest, coldest and weirdest volcanoes - and a look inside what makes them erupt.The volcano - among the most familiar and perhaps the most terrifying of all geological phenomena. However, Earth isn't the only planet to harbour volcanoes. In fact, the Solar System, and probably the entire Universe, is littered with them. Our own Moon, which is now a dormant piece of rock, had lava flowing across its surface billions of years ago, while Mars can be credited with the largest volcano in the Solar System, Olympus Mons, which stands 25km high. While Mars's volcanoes are long dead, volcanic activity continues in almost every other corner of the Solar System, in the most unexpected of locations. We tend to think of Earth volcanoes as erupting hot, molten lava and emitting huge, billowing clouds of incandescent ash. However, it isn't necessarily the same across the rest of the Solar System. For a start, some volcanoes aren't even particularly hot. Those on Pluto, for example, erupt an icy slush of substances such as water, methane, nitrogen or ammonia, that freeze to form ice mountains as hard as rock. While others, like the volcanoes on one of Jupiter's moons, Io, erupt the hottest lavas in the Solar System onto a surface covered in a frosty coating of sulphur.Whether they are formed of fire or ice, volcanoes are of huge importance for scientists trying to picture the inner workings of a planet or moon. Volcanoes dredge up materials from the otherwise inaccessible depths and helpfully deliver them to the surface. The way in which they erupt, and the products they generate, can even help scientists ponder bigger questions on the possibility of life elsewhere in the Solar System.Fire and Ice is an exploration of the Solar System's volcanoes, from the highest peaks of Mars to the intensely inhospitable surface of Venus and the red-hot summits of Io, to the coldest, seemingly dormant icy carapaces of Enceladus and Europa, an unusual look at how these cosmic features are made, and whether such active planetary systems might host life.

For every galaxy in the field or in clusters, there are about three galaxies in groups. The Milky Way itself resides in a group, and groups can be found at high redshift. The current generation of 10-m class telescopes and space facilities allows the observation of the members of nearby groups with exquisite detail, and their properties can be correlated with the global properties of their host group. Groups in the local Universe offer us the chance to study galaxies in environments characterized by strong interactions. In the cosmological context, groups trace large-scale structures better than clusters, and the evolution of groups and clusters appears to be related. All these aspects of research on groups of galaxies are summarized in this book written by scientists working in various fields.

This book discusses how the increased emanation of radon and other gases from the Earth¿s crust in the vicinity of active tectonic faults triggers a chain of physical processes and chemical reactions in the atmospheric boundary layer and the Earth¿s ionosphere over an earthquake area several days/hours before strong seismic shocks occur. It presents the two main concepts involved in this mechanism: atmosphere ionization and the global electric circuit. The Lithosphere-Atmosphere-Ionosphere Coupling (LAIC) concept is strongly supported by experimental data showing the atmospheric and ionospheric precursors for major recent earthquakes including 2004 Sumatra; 2008 Sichuan, China; 2011 Tohoku, Japan; and 2015 Nepal. The book not only addresses the theoretical considerations but also includes information on experimental techniques used for precursor observations based on the space-borne systems. Providing practical methods of precursor identification and interpretation, it is an excellenttextbook for graduate courses in geophysics, earthquake science, atmospheric physics and remote sensing. Moreover, it offers a wealth of information for scientists and experts from governmental and international agencies working in the fields of natural-disaster mitigation, response and recovery.

Planetary Systems Now offers a broad, interdisciplinary perspective and introduction to the latest results from leading experts in each field. It offers an unusually wide range of research on topics both inside and outside of the solar system, as well as the most recent results from ongoing ground- and space-based investigations. Experts in their field come together in this volume to discuss solar system exploration with its most recent space missions, theories and evidence concerning planetary system formation, and the nature and formation of exoplanets and exoplanetary systems.Including both questions and answers, this book is intended to be a readable, heavily-illustrated stepping-off point for advanced undergraduate students, graduate students, and scientists beginning research in planetary and exoplanetary science topics.

Emigrating Beyond Earth puts space colonization into the context of human evolution. Rather than focusing on the technologies and strategies needed to colonize space, the authors examine the human and societal reasons for space colonization. They make space colonization seems like a natural step by demonstrating that if will continue the human species' 4 million-year-old legacy of adaptation to difficult new environments. The authors present many examples from the history of human expansion into new environments, including two amazing tales of human colonization - the prehistoric settlement of the upper Arctic around 5,000 years ago and the colonization of the Pacific islands around 3,000 years ago - which show that space exploration is no more about rockets and robots that Arctic exploration was about boating!

The discussions in this book update Wind Energy since the publication of 2011 Handbook by Dr. Rao in Chapters 1, 2, 3 and 4. Since the coverage in the 2011 Handbook is considered applicable even for the present it is retained in total with the contributions for original authors for Chapters 1, 2, 3 and 4 an update for Chapter 6, 7, 8 and 9 of the 2011 Handbook.Chapter 1 covers "NASA Developments and Potential"; Chapter 2 addresses "Scope of Wind Energy Generation Technologies since 2011"; and Chapter 3 "Scope of Wind Energy in the US since 2011; and Chapter 4 "Wind Energy in the Netherlands Since 2011".Chapter 5, an update of Chapter 10 of the 2011 Handbook is titled as before in the 2011 Handbook, "Role of Wind Energy Technology in India and Neighboring Countries" by original author M.P. Ramesh and finally the last Chapter 6 is a new Chapter "Artificial Intelligence in Wind Energy" by Dr. Weifei Hu.The book contains over 200 pages with 28 tables, 143 figures, 379 footnotes and over 102 additional references in this updated version. The book has an index as before in the original edition, to help users easily navigate through the text and graphics.

By the star physicist and author of multiple #1 Sunday Times bestsellers, a major and definitive narrative work on black holes and how they can help us understand the universe. At the heart of our galaxy lies a monster so deadly it can bend space, throwing vast jets of radiation millions of light years out into the cosmos. Its kind were the very first inhabitants of the universe, the black holes.Today, across the universe, at the heart of every galaxy, and dotted throughout, mature black holes are creating chaos. And in a quiet part of the universe, the Swift satellite has picked up evidence of a gruesome death caused by one of these dark powers. High energy X-ray flares shooting out from deep within the Draco constellation are thought to be the dying cries of a white dwarf star being ripped apart by the intense tides of a supermassive black hole ? heating it to millions of degrees as it is shredded at the event horizon.They have the power to wipe out any of the universe's other inhabitants, but no one has ever seen a black hole itself die. But 1.8 billion light years away, the LIGO instruments have recently detected something that could be the closest a black hole gets to death. Gravitational waves given off as two enormous black holes merge together. And now scientists think that these gravitational waves could be evidence of two black holes connecting to form a wormhole ? a link through space and time. It seems outlandish, but today's physicists are daring to think the unthinkable ? that black holes could connect us to another universe.At their very heart, black holes are also where Einstein's Theory of General Relativity is stretched in almost unimaginable ways, revealing black holes as the key to our understanding of the fundamentals of our universe and perhaps all other universes.Join Professors Brian Cox and Jeff Forshaw in exploring our universe's most mysterious inhabitants, how they are formed, why they are essential components of every galaxy, including our own, and what secrets they still hold, waiting to be discovered.

H.T. MacGilLIVRAY Royal Observatory Blackford Hill Edinburgh EH9 3HJ Scotland U.K. lAU Symposium No. 161 on 'Astronomy from Wide-Field Imaging', held in Potsdam, Germany, during 23-27th August 1993, was the first conference organised by the recently-formed Working Group of lAU Commission 9 on 'Wide-Field Imaging'. This Working Group was instigated during the XXIst meeting of the General Assembly of the International Astronomical Union in Buenos Aires in 1991, and represented a merging of the former formal lAU Working Group on 'Astronomical Photography' and the informal 'Digitised Optical Sky Surveys' Working Group. Dr. Richard West was 'invited' to be Chairperson, and hence was given the daunting task of organising the Group from scratch. The very fact that the first conference after only two years was a major lAU Symposium says much about the determination and enthusiasm of Richard West to fulfilling the aims of the new Working Group. The siting of the conference in Potsdam in formerly East Germany provided an excellent opportunity to advantage from the political changes in Eastern Europe. Good access to the meeting was possible by scientists from Eastern European countries, allowing exchange of information on the very important Wide-Field facilities in both East and West, information on the rich archives of photographic plates that exist in both East and West, and allowing discussions between scientists facing very similar problems in both East and West.

Space is a large natural plasma laboratory offering a wealth of phenomena which range from the simple to the highly complex and non-linear. This book begins with an introduction to basic principles such as single-particle motion, magnetohydrodynamics and plasma waves. It incorporates these concepts into an analysis of complex phenomena including the sun and solar activity, shocks, interplanetary space and magnetospheres, and finally the interaction between these entities in solar-terrestrial relationships. In all these subfields of space research, special attention is paid to energetic particles. The book concludes with a brief chapter on instrumentation. In this third edition, numerous examples have been added to illustrate the basic concepts and aid the reader in applying such concepts to real world physics. In addition, recent observations (ACE, TRACE, Wind) have been included. The chapter on solar-terrestrial relationships has been expanded to introduce the current research topic of Space Weather.

Recent discoveries of planet-like objects circling other sun-like stars have stirred enormous interest in what other planets may exist in the universe, and whether they could support intelligent life. This book takes us into the midst of this search for extrasolar planets. Unlike other books, it focuses on the people behind the searches -- many known personally by the author -- and the extraordinary technology that is currently on the drawing boards. The author is an experienced, award-winning science journalist who was previously technology correspondent for the Financial Times of London.
