In this work, Prof. Arnold Hanslmeier provides modern and fascinating astronomical knowledge. The book begins with a description of the origin of the universe and goes on to dark matter, black holes and the formation of the solar system. Finally, it is rounded off at the end by the exciting question: Are we alone in the universe? In this book, which originated from a lecture given at the University of Graz for students of all faculties, the author explains the interrelationships clearly and in a generally understandable way with the help of many colorful pictures, without demanding too much basic knowledge of mathematics and physics. Somewhat deeper formulas and text passages are separated from the rest of the text and can be skipped without losing the context. This third edition incorporates new findings such as the spectacular direct discovery of gravitational waves, fascinating images and data from Pluto, and the first landing on a comet. Numerous new photographs and illustrations have been added to aid understanding. The latest data in the field of exoplanet research has also been incorporated. The book is intended not only for students, but also for interested laymen as well as for all those who deal with modern findings of natural science. "Physics, especially astrophysics, can be extremely exciting, I hope my readers gain just that impression by reading this book!" A. Hanslmeier The author Professor Arnold Hanslmeier is an astrophysicist at the Institute of Physics at the University of Graz. In addition to more than 400 scientific publications and several reference books, he also devotes himself very much to the comprehensible dissemination of the fascinating findings of modern astrophysics. He lectures at the University of Graz and is a visiting professor at the Universities of Vienna, Innsbruck, Toulouse, La Laguna, Tenerife and the Kiepenheuer Institute in Freiburg. Due to his special didactic abilities to present complicated things in a simple and clear way, he is an internationally sought-after speaker.

This second edition is a great enhancement of literature which will help the reader get deeper into the specific topics. There are new sections included such as space weather data sources and examples, new satellite missions, and the latest results. At the end a comprehensive index is given which will allow the reader to quickly find his topics of interest. The Sun and Space weather are two rapidly evolving topics. The importance of the Sun for the Earth, life on Earth, climate and weather processes was recognized long ago by the ancients. Now, for the first time there is a continuous surveillance of solar activity at nearly all wavelengths. These data can be used to improve our understanding of the complex Sun-Earth interaction. The first chapters of the book deal with the Sun as a star and its activity phenomena as well as its activity cycle in order to understand the complex physics of the Sun-Earth system. The reader will see that there are many phenomena but still no definite explanations and models exist for many of them. Other topics are the influences on the Earth's atmosphere, long and short term climate variations. The last chapters discuss the protection against enhanced radiation environment in view of upcoming manned missions to the Moon and Mars, and the threat from space debris, asteroids and meteoroids. Since the field is quite interdisciplinary, the book will be of interest to scientists working in different fields such as solar physics, geophysics, and space physics.

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.

The concept of summerschools and workshops at the Kanzelh¨ ohe ¨ Solar Observatory,Karn ¨ ¨ ten,Austria,devotedtoup-to-datetopicsinsolarphysics has been proven to be extremely successful, and thus in August/September 2003 the third combined summerschool and workshop was held there. This book contains the proceedings of the Summerschool and Wo- shop Solar Magnetic Phenomena  held from 25 August to 5 September 2003 at the Solar Observatory Kanzelh¨ ohe, ¨ which belongs to the Institute for Geophysics, Astrophysics and Meteorology of the University of Graz, Austria. The book contains the contributions from six invited lecturers. They give an overview on the following topics: observations of the pho- sphere and chromosphere, solar ?are observations and theory, coronal mass ejections and the relevance of magnetic helicity, high-energy radiation from the Sun, the physics of solar prominences and highlights from the SOHO mission. The lectures contain about 25 to 30 pages each and provide a valuableintroduction to the topics mentioned above. The comprehensive lists ofreferences at theendof each contribution enablethe interested reader to go into more detail. The second part of the book contains contributed papers. These - pers were presented anddiscussed in theworkshop sessions during the afternoons. The sessions stimulated intensive discussions between the p- ticipants and lecturers.
