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!

This is an excellent course on Astronomy, taught by a top Professor in the field. It kept me fascinated and eager to learn more, throughout the course. I enjoyed the practical assignment of imaging a part of the universe through MicroObservatory.

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.

Good comprehensive course. Some of the videos and materials now out of date and could do with updating, e.g. could talk more about the James Webb Telescope, and MicroObservatory and GalaxyZoo does not always work. But that is my only issue.

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.

this course is amazing .I gained a lot more confidence in my astrophysics and astrology which is my hobby as well as talent .the professor sir chis impey is amazing and tell deeply about the universe in avery easy and understandable manner

Very fun introduction to Astronomy course. I like how the professor links external contents which are fun and compelling to the lecture videos. Also professors often have a Live Q&A sessions which is great for taking the knowledge further.

Thank you once again to Prof Impey and his team for putting together a professional and comprehensive course that can be understood by non-astrobiologists and at the same time does not dilute the quality of the information. Gordon Ralph.

Excellent professor and course material. Understandable for me (a 11th grader who doesn't live in the USA) and I really enjoyed every minute of the lectures. Perfect choice for anyone who wants to know more about astronomy than Discovery.

Excellent course. Great way to get up to speed on the current questions and areas of investigation in the field of astronomy today. I truly enjoyed the course [well except maybe the writing assignments... ;-) ] and highly recommend it.

Um curso superinteressante para quem tem curiosidade, mas com muito conteúdo para quem quiser se aventurar nessa área. Foram 11 semanas de muito aprendizado e descobertas fantásticas sobre a origem de tudo o que conhecemos como Universo.

In this course I learned some interest things about the space and astronomy I didn't know before I started the course. And something I knew, with course I could improve my knowledge about that, so I learn to much things with this course.

Dr. Impey provides a stimulating overview of Astronomy in this course, replete with interesting historical facts at the start, and subsequently leading students through an exploration of astronomical objects, cosmology and astrobiology.

Excellent course. Professor Impey is fantastic. I've completed both of his courses on Coursera and my only wish is that there were more! The "Galaxy Zoo" website is a takeaway from this course that I see myself using lots in the future.

If you are interested in the field of astronomy, Astronomy: Exploring Time and Space is a great introductory course. Professor Chris Impey did an awesome job with the videos, they were very informative and the textbook was well written.

Excellent Course. I want to take a more advanced course. I learned more than I expected and refreshed my current knowledge in astronomy. One of the best classes I have ever taken. The online structure is super easy to learn and retain!

I loved every minute of this class, and all of the materials. Especially since I could learn at my own pace, not worrying about meeting deadlines. I have learned so much more about a topic that has always been a deep interest of mine.

It is a great course for both people who are new to astronomy and to people who already have some knowledge about it. Ir provides solid information in an engaging way, and I really enjoyed it! The live sessions were especially useful!
