      Fascination astronomy

      A cutting-edge introduction for all those interested in the natural sciences

      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 colourful 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 Chaotic Solar Cycle

      • 236 pages
      • 9 hours of reading

      Focusing on solar activity and its periodic variations, the book explores the solar activity cycle, including low and high phases like the Maunder minimum. It introduces chaos theory to analyze the chaotic behavior of solar activity and examines its impact on Earth's climate and space weather. The text reviews theories related to the solar dynamo mechanism and includes references for further study. Richly illustrated, it caters to a broad audience and serves as a valuable textbook for solar physics and astrophysics courses.

      The Chaotic Solar Cycle
    • 2018

      Astrobiology refers to the study of the origin, evolution, distribution, and future of life in the universe. This encompasses extraterrestrial life and life on Earth. Astrobiology is an interdisciplinary field that is gaining a rapidly growing interest among both the general public and the astronomical research community. This e-book explains the detection and evolution of exoplanets and discusses the question of habitability on such objects. Chapters in this text include cited references enabling the reader to acquire more information on specific aspects of astrobiology. It is also a suitable textbook for introductory taught courses in universities and colleges on the subject.

      Astrobiology, the Search for Life in the Universe
    • 2018

      Focusing on the burgeoning field of exoplanet research, this book delves into the concept of habitability, emphasizing its reliance on stellar activity. It explores how space weather influences both solar system bodies and distant exoplanets, offering insights into the conditions necessary for life beyond Earth. The content is tailored for those interested in modern astrophysics and the potential for finding habitable worlds in the universe.

      Auszug…. Nun wisst ihr eigentliche weshalb es im Sommer warm und im Winter kalt ist?„ Die beiden BVs blicken einander an. “Wahrscheinlich ist die Sonne im Winter weiter weg von uns als im Sommer„ meint BV2. “Beine, es ist genau umgekehrt, wir sind im Winter näher bei der Sonne als im Sommer", weiß BV1, doch wie das mit den Jahreszeiten wirklich funktioniert kann er auch nicht erklären…..

      Habitability and cosmic catastrophes

      • 248 pages
      • 9 hours of reading

      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.
