This is an excellent course. I have learnt a great deal and found the course easy to follow when broken into bite size chunks. The quizzes and coursework have reinforced my learning. I would recommend this course for anyone who wants to learn about our universe.

Excelente profesor con unos conocimientos muy amplios y explica muy bien . Yo no tengo la suerte de saber ingles y antes de comenzar lo traduzco al español con google y luego le sigo a el de esta forma le entiendo bastante bien .

muy agradecido

The course is very well structured and touches a large range of topics. Professor Impey makes some of the lecture material very interesting and has simplified complex theories and concepts. However the Astropedia textbook needs to be updated with recent events.

I thought this course was outstanding. The content was very interesting. I especially appreciated the delivery and style of Prof. Chris Impey in the lectures. It was easy to follow, very informative, and kept my attention. I'm very glad I took this course.

I feel much more confortable speaking/listening about the universe now that I have a strong base, I watch the lives made by Professor Impey and I feel really happy to be confortable understanding what he is talking about. I love it from the bottom of my heart

I have enjoyed this course! It was well organized and I have learned so much more about Astronomy than I could have ever Imagined. Chris Impey is an outstanding professor and I am so glad I had the opportunity to take this course and complete it. Thank you.

Esse curso é muito interessante! Valeu muito a pena investir essas semanas nele. O professor ensina o conteúdo de forma clara e muitas vezes divertida, com bastante exemplos, imagens e vídeos. Super recomendado até pra quem não entende muito de Astronomia.

Awesome course! Professor Impey is very knowledgeable on the subject. So fortunate to have had him! Wanted to be an astronaut as a kid but everyone told me I would die in space. At least now I have some knowledge on the subject! Astronomy is AWESOME!

It was my first course on Astronomy, and I think is the best compilation of a vast number of concepts in a manner that is easy to understand and imagine. This was really inspiring.

Perhaps you may start to consider the subject as a new carrier to pursue.

Very interesting and informative course; incredible in its scope of course material. The lectures are well done, and the textbook provided is an easy to understand yet comprehensive tome. If you have an interest in astronomy, definitely take this course!

Very organized and funny! I felt like having building some new synapses and basic knowledge about what has been occurring out there. Next time I observe the night sky, for sure my perception would be different and a little bit more accurate. Thank you!

Professor Impey has created an engaging and up-to-date course that invigorated my desire to learn. This is an involved and comprehensive class and covers astronomy protons to black holes. You really need to invest studying time to get a passing grade.

Awesome, though sometime i could not follow up the week schedule, everything goes fine with my delay as well as late submission of assignment too. Hence, i could grab what instructor wanted to easily and practical assignment is also very interesting.

Awesome course i have ever had! I got clearly explained about astronomy. But the problem was in some videos... there is a disturbance noise, which causes problems when wearing headphones. But awesome! I recommend this course for a amateur Astronomer

amazing course! I really enjoyed working with professor Chris Impey, the classes are entertaining and he nows how to get your attention with good supplementary videos and amazing facts. I hope one day I get the chance to meet professor Chris Impey.

It is a marathon more than a sprint kind of course - 10+ weeks!-, but definitely I enjoyed it from beginning to end. Pfr. Impey is a top-level scholar, who makes this amazing field of knowledge accessible and easy to follow. Totally recommendable!

​Es un curso muy completo y se aprende muchísimo. El prof. Impey es muy claro y aporta datos muy interesantes, por lo que se hace bastante ameno a pesar de ser un curso de 11 semanas. Tiene opción de subtítutos multilenguaje, por si se necesitan.

If someone is interested in Astronomy, taking this course one of the best investment of his time. The course is instructed by a brilliant instructor Chris Impey. He makes difficult concepts easy to understand. Recommended for every science lover.

I have no words to describe my enthusiasm and my gratitude to Prof Impey and all the stuff for this course. Definitely, one of the best structured and updated courses. Strongly recommended. Nevertheless, quizzes should be slightly more difficult.

And Incredible Course that allowed me to explore the vastness of space and time,and understand even a little the magnificent and divine universe.

very grateful to Professor Chris Impey and the steward observatory teaching team for the opportunity

This is a great introduction to Astronomy that covers a lot of ground. I thoroughly enjoyed all of the video lectures and feel like I've a better understanding of the field of Astronomy. The online textbook is a fantastic resource. Many thanks!

After acquiring 2 masters degree and beginning work on a doctorate I have found a course that has taught me more than many of the courses that I have taken in person. Astronomy: Exploring Space and Time has been very well designed and taught.

This course has been a delight to me for the past 3 months. Professor Impey is an outstanding one and I am looking forward to taking "Astrobiology: Exploring Other Worlds" as I am quite sure that it's equally interesting and stimulating :)

This course is really awesome. It is excellent for starting Astronomy. It gives a review of from where man started to explore the universe and where he is now. It tells you about the horizon and now its your duty to walk beyond the horizon.

This course is so well planned and well taught by the faculty. I really liked through out the course and enjoyed every minute of the lecture. A whole new experience I had have. And highly recommend this course you will definitely enjoy it.
