The professor moves very fast, but is good at explaining complicated concepts and giving examples that are very helpful. In this format, it's easy to go back and review so the fact that he moves fast isn't really a problem.

The course is exceptionally good provides a large amount of information. Starting from beginning to a mixed-intermediate method and will be very helpful for enhancing your knowledge about the various concept in the universe.

Amazing course, it covers almost every aspect of astronomy. History, stars, exoplanets, etc.

Lovely course for astronomy enthusiasts. The assignments really make one do actual research and then think and wrote their answers.

This was an awesome course for beginner astronomers and backyard astrophysicists. From the Big Bang to the present is featured elaborately in this course.Thank you everyone for making this course for astronomy enthusiasts.

Excellent introduction! Whils many of his topics are beyond the understanding of my untrained and unscientific brain, I was able to retain enough of the larger concepts to have a better grasp of the nature of the universe.

Honestly one of the best courses out there. It is explained really well and overall a very enjoyable experience. Professor Impey is a great teacher and I'm thankful that I had this opportunity to take part in this course.

Exhilarating course, interesting from the start till the very end. The material is split very logically and every week you delve deeper and deeper into space. An absolute recommendation for anyone interested in astronomy!

It was a very interesting course. Professor Impey is a wonderful lecturer with a great mind and an enthusiasm for his subject. It is just the right level for one who wants an introduction to astronomy with broad coverage.

Very interesting class. At begining, I know nothing about Astronomy. I'm glad for have followed this class all overs these weeks, every week a new surprise about our infinite universe. I'll recommand it to all my friends.

Excelente curso y muy apasionante. Logran hacer de los videos un aprendizaje muy ameno y las lecturas complementarias están muy bien fundamentadas. Este curso me dejó con ganas de seguir aprendiendo. Saludos desde Chile!

Loved it. Learnt so much my head hurts (in a good way)!!! I would recommend this course to anyone wanting to develop a greater understanding of our place amongst the stars and what goes on all around us in the universe.

One of the best courses around. It's not a graduate course, and it does not teach you the secret of physics, but the compact, vivid presentation gives you a great overview of the field and of the exciting things to come.

A very clear study for beginners in astronomy. Some concept might be a little too hard but is acceptable. Good use of resources, especially outside videos to support teaching of the class which makes the class more fun.

Great course for students willing to study Astronomy or Astrophysics, and has a lot to offer. Professor Chris Impey has been a great teacher throughout the course, and I'd love to take any other course he has to offer.

The teaching team had been very helpful in handling every students questions in the discussion Thread. The YouTube Live QnA session also exciting! Salute for the "Astronomy: Exploring Time and Space" teaching team! :-)

Thank you Professor Impey for your clear and concise teaching in astronomy. I've gained so much knowledge and insights through your course. It has renewed my view of the universe and my humbling place in the universe.

This course is the Master of Astronomy. I'm highly recommending this course to those who are interested in knowing about outer space. This course is suitable for anyone regardless of age and educational qualification.

This course is the second couresera course which completed. It is always nice to learn from people who do frontier work in the field they teach. I thank coursera for giving me this wonderful opportunity. Sakthivel

This course widened my knowledge about Astronomy and related fields. Professor Impey was able to deliver the materials well, and was able to impart many knowledge to me. I will certainly enroll in his other courses.

This course is amazing. It is especially wonderful if you are looking to pursue a career in Astronomy, or learn Astronomy for extra knowledge. I would highly recommend it, as well as the instructor Dr. Chris Impey.

The course is very good. It provided me with lots of knowledge. It consists of lots of information to learn and lots of activity to do. Thanks to the instructor for describing the informative topics so beautifully.

The professor Cris have done very good job to explore us in space and time

I love this course and iam fascinated from my childhood to learn about this subject

Thankyou University of Arizona and team Coursera ❤️❤️❤️ .

By far one of the best courses I have taken on Coursera. The amount of material is astounding and of great quality through and through. I highly recommend this course. Be prepared to work for your diploma, however.

this course was very helpful. Astronomy has always been one of the most interesting topics. There is so much about this universe that is unknown to mankind. this course has covered almost every topic in astronomy.

Interesting and really enjoyed. Basics of the whole life, how, when and where we are..through the exploration of astronomy. Special thanks for the professor and for the organization.. Really nice experience here.
