Very interesting and informative course, the instructor is actually really engaging. However, after week 3 it seems that the instructor just wanted to get it over with, having videos of 6-8 minutes covering topics that astrophysicists would need twice the time to comprehend (like the methods of searching for exoplanets). And the fact that after a 15-20 minute collection of videos you need to take a quiz of 20 questions, means that the instructor actually spent less than a minute explaining each one of these questions. Overall, it was a great course, which I totally recommend to anyone who is interested in learning a few basics in astrobiology, however, in my opinion, for those of us who have zero to limited knowledge of astrobiology, this introduction to astrobiology should have been a little more detailed, with longer videos explaining all these interesting topics with greater detail.

Astrobiology is a fascinating area and Professor Cockel clearly presents a well organized introduction to the subject. His presentations are clear, concise and enjoyable. As a scientist with little knowledge of astrobiology, I learned a lot and thought my course time was well spent. Having said that, I must add that the course is very dated. Professor Cockel's discussions are almost 10 years out of date. As I write this, the US has landed a spacecraft on Mars and I am astounded by the photographs that have been sent back to earth. This makes the course of ten years ago seem even more dated. Nevertheless, the course provides a solid foundation to the field. I thought that some the quiz questions were more than a bit tricky and picky. Who remembers how many countries were in the UN at a specific time in history?
