A great opportunity to learn a lot of things especially in terms of seeking the origin of life here on our planet Earth and beyond in the vast universe. Thank you for the knowledge and everything.

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 Professor Cockel's discussions are almost 10 years out of date.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?

I love this course, it gave me the basic idea of how life could and couldn't start with one situation or another. The impact of some element in our life and how alternative elements have smaller chance to be the backbone of life is not a common thing to think in my everyday life (a fresh air for me)

I have difficulty to remember all the project that we all do to search the extraterrestrial life though XD...this course make me think that I now have a basic scientific facts to start build a new story about the early life in earth <3 oh my god, thanks a lot sir!! (^u^)v

The course has been very interesting and has motivated me to pursue this field further as a researcher. However, the pieces of information are really outdated, as old as of 2012, so I would like to request Prof. to update the course as much as possible. In the course certificate, the overall grade is not depicted, therefore, I request coursera to look into this matter. Nevertheless, it gives me immense pleasure to undergo this course and I thank whole-heartedly to Prof. Cockell and coursera as well.

About the contents, I was expecting maybe less biological charge and a bit more about astronomy, but maybe that was my mistake. The teacher makes a great job, and I have been learning both astrobiology and English. About practicing English while studying another subject, I would like to appreciate the synchronizing of the subtitles, that were perfect.

I totally recommend this course to anyone interesting in solar system, astronomy, biology and the search for extraterrestrial inteligence.

This course was very informative about the current scientific research beyond our Earth and beyond the solar system. I give it four stars because all the information in the lectures and video did not cover tested material. I had to go outside of the course to find some of the information required in the quizzes. I do believe that some of the information could be updated for 2019. Thank you very much for offering this course! I will be looking for more courses with similar topics.

This was a fun course, and I'm glad that I took it, however I wish that we learned a bit more science, perhaps about what work is currently being done that might encourage us to go into the field. Or perhaps there isn't much that can be done at the moment, because we are only just getting the technology and telescopes to have the ability to do interesting things in this area. I think the next 20 years will be a very exciting time for astrobiology.

Almost perfect (for the intro level it was designed for). I would suggest that next time, if possible, instructor image could be a little smaller and the actual images illustrating the points he is talking about a little bigger and more diverse. But that is a minor, please, don't get me wrong. The course was very very good, thank you a lot. Also, the off-line written forum-style discussions were very very good.
