In this work, Prof. Arnold Hanslmeier conveys modern and fascinating astronomical knowledge. The book begins with the description of the origin of the universe and extends to dark matter, black holes, and the formation of the solar system. It concludes with the intriguing question: Are we alone in the universe? The book, which originated from a lecture given at the University of Graz for students of all faculties, explains the connections clearly and understandably with the help of many colorful images, without requiring too much foundational knowledge in mathematics and physics. More complex formulas and passages are separated from the main text and can be skipped without losing context. In this third edition, new findings such as the spectacular direct discovery of gravitational waves, fascinating images and data from Pluto, and the first landing on a comet have been included. Numerous new images and illustrations have been added for better understanding. The latest data in the field of exoplanet research has also been incorporated. The book is aimed not only at students but also at interested laypeople and anyone engaged with modern scientific discoveries. "Physics, especially astrophysics, can be extremely exciting; I hope my readers gain exactly this impression from reading this book!" A. Hanslmeier.
