A very enjoyable, informative and interactive course.

Amazing course !

great Experience ,happy to learn

There are some questions even when the correct answer is put, it is not accepted, it should have been changed, and option questions were put

Professor Impey and his team do an outstanding job of making an already fascinating topic such as astrobiology, a joy to learn. Their videos and assignments reinforce the scientific method and the structure to write a successful scientific paper not only for astrobiology, but for other fields of science as well. Professor Impey's summaries at the end of each video always provide an excellent review of the study material. Furthermore, professor Impey's biweekly live study sessions offer an opportunity to clarify topics of the class, as well as to learn more about current events in astronomy, astrobiology, and space exploration. Professor Impey's vast subject matter expertise and generosity to patiently explain complex scientific challenges are tremendously appreciated. Thank you so much, professor Impey!

Professor Impey imparts the most technical information in a way that is understandable and retainable. The class captures the beauty of the unknown , engaging in the most profund way. The structure was such, that it was easy to take the short quizzes, but it also made me go back and rethink and refresh some point without overwhelming me. The written assignments at first seemed hard, but were clever , in that they reinforced the technical classification of planets in the universe, and of what interest they would be to explore. Although I have always believed in life on another planets, this course gave me more undeniable scientific facts to support a high probability of life on other worlds.

This course was very interesting and I enjoyed it. I also learned some things that will help me in other areas, too,such as don't give up; there may be more than one answer to a question-consider answers carefully, and the final project was especially good in driving you to think carefully about many factors and possibilities and reasons for and against several candidates and options for a future exoplanet mission. That is, it really gets you thinking and not just memorizing rote facts. Grading others has benefits, too, realizing that others may have good points to consider, in addition to your own.

Thoroughly enjoyed this scientific interdisciplinary course. I am now understand what and how we have discovered about the solar system and universe, what we are doing and what is planned. Also I thoroughly enjoyed the final assignment on planning a partial fantasy trip to an exoplanet of my choice. Great fun. I especially love podcast interviews by Professor Chris Impey with experts. Thank you so much. My certificate, along with Astronomy certificate and Einstein Special Relativity certificate are on my kitchen wall.

A completely engaging course with one of the best lecturers I have encountered on Coursera. Full of engaging lectures on a fascinating subject. Multiple quizzes to keep you on track. Fun projects (only fun if you like challenging projects!), and a course that makes the field of Astrobiology understandable to an every day non-astrobiologist. Dr. Impey has a way of explaining things that makes it all seem simple. I almost want to retake it!

This course has been the best course in astrophysics I ever attended. Its organisation was perfect, the quizzes and papers to write to the point. But more importantly, Professor Chris Impey has been remarkable in presenting the subject and getting me inspired and the best teacher ever in courses I joined. As a result, I immediately signed up for another course he gives online. Thank you Professor Impey.

Highly recommended course if you like biology and astronomy. Learn a lot about the types of planets, stars, habitability conditions, elements to look for as they may be signs of life on that planet, and above all, learn that we are not alone in the universe! I recommend it to those people who, either sleeping or awake, dream of visiting space or dedicating themselves to astrobiology in the future.

An extremely well-structured course. The teaching methods used a very engaging, and the content is not too difficult to learn for complete novices to learn - like I was. There are some tasks to complete, but these turn out to be quite satisfying and rewarding and are never exhaustive or too extensive. My advice would be to try the course for 2 weeks out of the 6, to see what you think. Good luck!

This course has surpassed my expectations. It covered an incredible array of topics related to Astrobiology and even proved the knowledge via assignments. Highly recommend for any beginners in the topic since the instructors combine terminology with images, examples, and even short movies. Also, the course is divided in such a way that each week's lessons and themes backup the ones ahead.

This was a great course, lots to learn along the way. If you are interested in earning the certificate then be sure to keep on track and submit assignments on time or a day or two ahead if possible to anticipate for the delay of grading assignments. I can diffidently recommend this course for anyone interested in the field of Astrobiology or similar field such as Astronomy. Thanks!

Professor Impey has put together another interesting, informative course! I particularly liked having the opportunity to apply my new knowledge via the Exoplanet Mission Proposal final project.

This is my second course with Dr. Impey. I am hopeful that he will create another course - he is a great professor who knows how to keep these somewhat-difficult subjects fun and lively.

Excellent course, I will recommend it to my friends, you learn a lot and it's important it is about life and Exoplanets, now I know what is the destiny of Humanity ! to reach the stars ... I would love Next Chapter to be about Synthetic life, A.I and bots our mandatory partners whenever we are ready to take off.

Congratulations to

Chris Impey an Excellent Professor

Excellent course. Excellent teacher. Fun. Enlightening. Inspiring. In Professor Impey's courses and podcasts on astronomy, physics, space exploration, and astrobiology you rarely hear him say "I don't know." He has deep and broad insights into all aspects of these disciplines. I recommend his astronomy and astrobiology courses on Coursera to any science student.

I am very thankful to Professor Chris Impey and Coursera for this wonderful course. I was always curious about outside world and this course has helped me learn a lot.

I really liked the different structure of this course that is peer reviewed assignments and quizzes after every video.

Thanking the mentor for addressing every problem faced by the participants.

Very thorough, accessible, and well organized introduction to a fascinating topic. Prof Impey creates a great workflow and progression, starting on grand themes and zooming in from there. This will be fascinating for anyone who likes to contemplate the stars, or is interested in cosmology, astronomy, the Fermi Paradox, or science in general.

This course is packed with great information about planet formation, exoplanet discovery, and the development of life. Chris Impey is very knowledgeable about astrobiology and properly breaks down what astrobiology is, and teaches those components in a way that makes sense. I love this course and the things it has taught me!

I appreciate The University of Arizona and especially Dr. Impey for putting this course on Coursera. I feel I really learned more in this course than a related one I took from Cal Tech where the TECHnical aspects made the material less translatable for understanding. That did not happen with this course. Splendid job!

As someone who has a love for astronomy, this course was educational and entertaining at the same time. I had an absolute blast learning from this course! The professor explained everything well and the first short video for every week explaining what the week will have was great and I thought it was a good idea.

I have now taken several courses from Coursera, but this was the first one I loved the whole time I took it! The structure was one of the best I have seen, and the instructor made the subject matter engaging and approachable. This course truly expanded my understanding of the universe and our place within it.

I found this course fascinating. It included a wide variety of topics when considering exploration of other worlds. Very comprehensive and thought provoking. Anyone can enroll, but everyone will learn! A big thanks to Professor Chris Impey for his impeccable teaching and wealth of knowledge.

Wonderful and well-organized course that will introduce you to the basics of astrobiology. Lectures are interesting, diverse and most important concepts are explained in very simple and understandable language. Some prior knowledge of astronomy and biology is welcome, but not necessary.
