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
