The field of solar physics and solar--terrestrial relation, now called space weather, is evolving rapidly. As in the first edition, it is assumed that it is inevitable for the reader to get some basic knowledge in solar physics since the Sun is the main driver for space weather The term space weather itself has been gaining more and more attention during the past years as our society becomes more and more dependent on satellites, which are vulnerable to varying conditions in space. Space weather efforts and investigations are being made all over the world and more and more is known about the complex relations of processes on the Sun and the Earth and its space environment. The term space climate nowadays includes the long-term variations caused mainly by the Sun on the Earth and the interplanetary space. As in the first edition of the book, this edition also covers these topics but new chapters have been introduced, e. g. , a chapter on real-time space weather forecasts and some main space weather data sources. All the chapters have updated information, taking into account the results of new satellite missions and telescopes. The book also includes a great amount of new literature (more than 340 original citations) so that the reader is able to go into more details, if required in the respective chapters.

The solar system has a rather well-known history. Looking at the present situation, one might get the impression that it was a rather stable and well-defined system: the orbits of the planets appear to be stable, climate and atmospheres on the planets have been determined, the risk of collision with other bodies (comets, asteroids, meteorites) seems to be small. However it is known today that the evolution of life on Earth was neither a steady progression nor uniform. There were several periods of mass extinction. These catastrophic events played a crucial role in the rise of new species. Events of astrophysical origin include: Asteroid impacts - Major solar variability (space weather) - Nearby supernovae - The passage of the solar system through dense interstellar clouds. Catastrophic cosmic events of this type appear in the range of some 100 million years. The author discusses whether and how such events could have occurred in the recently found extrasolar planetary systems. In this text, which addresses readers in the field of Astrophysics and Astrobiology but also Geophysics and Biology these cosmic catastrophic events are described at an intermediate student's level.

The search for life in the universe is one of the most challenging topics of science. It is not a modern topic at all, since more than 100 years ago, it was speculated that on the Moon, there are oceans and seas; on Venus, there are swamps and also Mars is inhabitated. However, now we have the scienti?c background and the scienti?c tools to answer this question and it is also certain that the answer would have deep imp- cations for our culture, philosophy, and religions. If we ?nd that life has developed on other planets or satellites of giant planets, then this would be the ?nal breakdown of our central position in the universe. But is life a widespread phenomenon? How vulnerable is it to changing conditions and even catastrophic events? These topics will be discussed in this book. If life is in the extreme case a unique phenomenon found only on planet Earth, which seems to be highly unrealistic, then also it is important to discuss how it is adaptable to changing external conditions. Can we survive a cosmic catastrophe? How do these catastrophes change habitability? Which forms of life are more v- nerable? It was mentioned that now science has made great progress to answer such qu- tions. Let us give some examples. In modern biology, in connection with organic chemistry, the origin of life is studied.

Die Beobachtungsmöglichkeiten der modernen Astrophysik werden immer zahlreicher. Sie reichen von optischen Teleskopen über Weltraumteleskope im Infraroten bis zu Radioteleskopen und von Gravitationswellendetektoren bis hin zu Neutrinoobservatorien. Während die einen im Weltraum ein Augenmerk auf das Licht werfen, nehmen andere unter Wasser kleinste Teilchen unter die Lupe oder messen Störungen der Raumzeit, die kleiner sind als der Durchmesser eines Protons. Das Buch bietet einen spannenden umfassenden Überblick über unsere technischen Möglichkeiten, das Universum zu erforschen. Als Grundlage für eine Vorlesung in Astronomie bzw. Astrophysik ist es ebenso geeignet wie als Lektüre für naturwissenschaftlich Interessierte.

The observation capabilities of modern astrophysics are constantly increasing. They range from optical telescopes and space telescopes in the infrared to radio telescopes, and from gravitational wave detectors to neutrino observatories.

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.

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 whole text is written in a clear and light scientific style. It is fully referenced to scientific publications and supported by numerous figures, mainly in full colour … The present book can be recommended to any interested reader with a background in physics and/or astronomy, in particular to undergraduate and graduate students within astronomy and related fields, possibly being also of interest to scientists in (evolutionary) biology."Contemporary PhysicsThe search for exoplanets and habitable objects in general is one of the fastest growing and most prominent fields in modern astrophysics. This book provides an overview on habitability on exoplanets. Habitability is strongly dependent on stellar activity. Therefore, space weather effects on objects in the solar system as well as on exoplanets are discussed.The concept of the book is to introduce the topics and then discuss actual scientific papers so that the interested reader has access to most recent research. Therefore the book is valuable to undergraduate students as well as to graduate students and researchers.

This textbook highlights mechanisms, properties, observations, and research progress of solar and stellar rotation. The textbook presents techniques that enable to determine rotation on stars and give a comparison of how stars rotate according to their spectral type and evolution.

Different techniques that enable to determine solar rotation (e.g., tracer method, spectroscopic method, helioseismology) are presented and their results are compared and interpreted.In the current literature there is no book exclusively about solar rotation published in the last several decades.
