Excellent introduction to Astrobiology and the remote study of exoplanets, whose we have just discovered a few and there are plenty to discover in our galaxy. The course is demanding, you must get 100 in the quizzes and a written homework for each module, but that is a good way to learn.

It's a course and a subject which will stay with you for a long time as the knowledge gained is immensely rewarding and interdisciplinary. You'll get to know more about the universe by delving into various fields of science like physics, astronomy, genetics, biology, geology etc.

I found the course to be insightful and thought-provoking. The lectures were clear and well-delivered, making it easy to follow along. Professor Impey enthusiasm for astrobiology is contagious, and it made me even more excited about the possibilities of life beyond our planet.

I have learnt many new things about our universe after doing this course and Sir Chris Impey really makes all the complex stuff easy for us. If you are curious about the universe and often ask the question about Extra-terrestrial life , this course is for you, Thank You !

What an amazing and inspiring journey it has been. I loved every bit of this course and it inspired be to pursue astrobiology as a career path. Thank you Chris for teaching in such a clear and wonderful way, hope one day I'll get to be your student in real life!

Enormously enjoyed taking part in this course. Prof. Chris Impey is a great teacher; his enthusiam and love for his field of work and clear explanations were of great help and cleared up the many questions there were. Looking forward to a sequel Chris!

A truly informative and fascinating course.

My only criticism is that, while I accept that the USA still uses the Fahrenheit scale, most countries use the Celsius scale. It would be even better, as this is a science course, if the Kelvin scale was used.

It was an excellent course. I hope professor Impey and his team design other courses to continue this course at the intermediate and advanced level, and students becomes more familiar with astrobiology with more details. My thanks and appreciation.

Well done, well structured, well-mastered course. I enjoyed every minute. Prof Impey is my favorite. I appreciate so much his work and his ability to explain in such a simple way complex conceptions. I am grateful. HIGHLY RECOMMENDED.

Excellent introduction to the subject, with high quality materials and opportunities for live sessions and Q&A's. Active forums and discussion help provide stimulus for further reading and taking the subject further. Highly recommend.

This is one of the most exceptional courses on Coursera that I have attended. I strongly recommend it to anyone. It exceeded my expectations and it is very up to date covering the discoveries in past 20 years. Keep up the good work!

O curso proporcionou conhecimento importante do campo da astrobiologia, dando nos dados e o real avanço da ciência nessa área, nós aprofundando na curiosidade de conhecer um pouco mais sobre o universo, que está aí para descobrimos.

The peer-reviewed assignments are an excellent way of showing understanding of the subject material. I would like the opportunity to be able to discuss and debate the choices for the last assignment with other course participants.

This course really helped me to expand my knowledge in the fascinating subject of Astrobiology. The video lectures given by Prof. Impey were totally awesome and easily understandable. I would highly recommend taking this course.

An excellent course. Very interesting content with thought-provoking assignments. I enjoyed the lectures, each was well presented and delivered. I would recommend this course to anyone curious about astrobiology and the cosmos.

Very fine course and I personally loved the instructor and his method of delivery. I would definitely recommend this to anyone who wants to get to know about this subject. Thanks to the team who worked on putting this together.

A very interesting and thought provoking topic. The course was very well organised and each section was fascinating, I will definitely continue to learn about astrobiology. My only disappointment is the course has finished.

Great lessons, great instructor and live sessions where you can ask all the questions you have about he course and extra astronomical topics. Thanks to the instructor Chris Impey and the team that made this course possible!!

I loved this course... absolutely unexpected how easy and relatable this very complex topic can be.

I even bought the book and I'm keeping up with the latest news on this very interesting topic.

Loved it!

Highly recommend it.

Finally I’m more aware of what surrounds me, in biological and astronomically point of view. This will be very important for my artistic research in the next futur. Thanks for creating this amazingly well structured course

Excellent course which provides an introduction to exoplanets, habitable zones, methods wtc. Highly recommended for anyone interested in Astronomy. Thanks to Prof. Impey and team for making this course available to us!

"Chris Impey's astrobiology course is a fantastic way for anyone to better understand the science behind our search for life in the universe. I highly recommend it!" - Tom Vassos, Founder, CosmologistsWithoutBorders.org

It was a great course! Super informative if you want to start learning the fundamentals of astrobiology. The course instructor is also great and explains everything thoroughly. I loved the live Q&A session aswell!

This was the first course I had taken in my life through coursera and I inexplicably enjoyed. The professor has an undoubtedly the best delivery I have heard so far. You will not regret taking this course.

Along with Astronomy: Exploring Time & Space also by the University of Arizona, this is one of the best and most enjoyable courses here in Coursera, especially if you have a great interest for astronomy.
