Astrobiology is the study of the origin, evolution and distribution of life in the universe. Ultimately, we wish to know where we came from, where we are going, and are we alone in the universe.
Astrobiology is interdisciplinary and brings together research from astronomy, astrophysics, atmospheric sciences, biology, chemistry, computer science, earth science, geophysics, planetary science, physics and philosophy.
This course is open to anyone in the university with no prerequisites. It is based on the book “Da Draussen -  Leben auf unserem Planeten und anderswo” by Ben Moore, published 2014 by Kein & Aber.
Course requirements: attend the lectures and problems classes. For the final exam you can choose between a 20 minute oral exam or to write an essay in the style of a Scientific American article.
