It has been a wonderful experience and I am very grateful to Coursera and its entire team for helping me complete this course. The dynamics they use are very practical and easy.

Excelente curso! A pesar de que podría necesitar actualizaciones está super completo y lo considero muy adecuado para principiantes que quieran adentrarse más en la astronomía.

The best course about astronomy I've been! There is no question that you will learn new stuff every week with Chris Impey. I appreciate all the material and support gave to me.

Excellent, i'm a fan of astrophysics and astronomy, not a practicioner. The content was very interesting. Good job both that of the professor and Coursera/University of Arizona

I have been interested in astronomy for many years and the course has increased my interest in this fundamental subject. I thought the course was excellent and I learned a lot.

This course is the best course I have seen and bring more interesting things to do more research on it.

The doubt session was also amazing.

Thank you so much --Prof. Chris Impey

Chris Impey is one of the best instructors I have ever taken a course with. He has the ability to take complex ideas and make them accessible to everyone. Highly recommend it.

i have learned too much about Astronomy, this course is very clear, explained in a very easy way, I am so glad to participate, and I hope have a second part of this course.

Great course, Professor Impey does a wonderful job of explaining this topic and keeping it interesting. Highly recommend his parallel book on the same topic, "How It Began".

This is the best course I have done in Coursera. The use of animations, videos, resources, The occasional humor and the way the lecturer addressed each topic. Simply amazing!!

A very interesting course about the basic concepts of astronomy with lots of additional funny videos and slides. Thanks a lot to professor Impey and everybody who created it!

This is a very thorough and informative introduction to the field of astronomy, and contains a lot of practical information that everyone interested in the night sky can use.

Great course! Very insightful and interesting. Goes over everything from history to current theories. Forums are very active and live streams (for Q&A) are frequent. Thanks!

Really enjoyed this course, wish we learnt more of this at school! Chris also hosts live sessions which are fantastic. Quirky music and TV show references, keeps things fun!

FANTASTIC COURSE. As an old retired physics major and dentist it was a great review of the current state of knowledge about the universe and astronomy. Wonderful Course!

I did this course as a skill for my bronze duke of edinburgh award and really enjoyed it, it was challenging but always provided everything necessary to complete the course

Very well explained, need no experience to do the course, thanks Professor for this great material and helping people get a better knowledge of this fascinating universe/s.

Great course!!! Learned so much. The text, slides, videos and lectures convey so much information in a way that is accessible and challenging. So glad it took the course.

Its is more informative and its very useful for our future to gain knowledge in astrophysics .Its very interesting ,hope to do more courses based on astrophysics .Thankyou!

This course covers almost everything you need to know about astronomy. Though it is informative, Prof. Chris Impey has covered every aspects of astronomy in very great way.

I always have passion for astronomy. So, This was very helpful. And I enjoyed learning Prof. Impey's lectures. Coursera gives you worthy knowledge and learning experience.

´É lindo poder ter acesso a um conteúdo tão rico em conhecimento. Eu amo astronomia, é interessante estar no meu país e assistir à aulas de uma Universidade tão exemplar !

really an interesting course, with lot of exercises and moments of thought about universe, mankind and science. Also a nice english-speaking, clear for non mother tongue.

This is the best course I have ever completed in my life. I am extremely thankful to Prof. Chris Impey and his team for making such a wonderful course. It's just amazing.

Beautiful, gorgeous and fascinating, one of the best courses ever followed; rich in content and explained with elegant clarity. Thanks for making it available to anyone.
