Diificult sometimes but surely a rewarding course in the end. I enjoyed it and I am looking forward to taking more advanced Astronomy courses.

Thanks Prof Impey and UA & Steward Observatory staff

Thank you for this excellent course Dr. Chris Impey and team! I'm a budding research scientist in the intersection of Astronomy and Computer Science. I didn't have the opportunity to pursue a formal course in Astronomy due to a lack of credits at my Univeristy. Although this course isn't mathematically detailed, I've gained a sufficiently broad view of the field, and it is more than I could ask for. The material is excellent, intellectually challenging, and humourous on multiple occasions. I would definitely recommend this course to anyone interested in Astronomy!

Having just finished the course successfully, I would recommend it to anyone who loves astronomy. Coming from a different scientific field , but with a great love for astronomy, I feel that this course clarified a lot of meanings and introduced me to great concepts. And although English is not a native language, the course as well as all visualizations and material used, were very clear. Professor Impey is very well understood and does not use technical details that could confuse. Thanks Professor Impey and the Steward Observatory Teaching Team!

The astronomy course exceeded my expectations. I learned a great deal from the video lectures and the astrpoedia textbook. I was surprised that preparing for the essay questions was also a good source for added knowledge in researching for the assignments. I am indebted to Chris Impey for the excellent lectures and course. Everything was well presented and explained well but I could not get up to understand much of the last lesson – Life in the Universe.

In summary, great course and recommend it without reservations. Kudos and thanks to Chris Impey.

This has been a very elaborate and detailed course on Astronomy. I was pleasantly surprised with the absence of any detailed mathematical computations used to explain the scientific phenomenon. Dr Chris Impey is simply outstanding. His way of teaching is superb. He has the ability to express highly complex subjects in Astronomy in a very simple way. I never faced any problem in understanding them all due to his excellent teaching. I sincerely wish that more and more students across the world join this course. Wish the Team Astronomy the very best.

I was looking for an introductory course in astronomy. This course did not disappoint. It was informative and interesting throughout, and covers a wide variety of related topics, including physics and biology. The lecturer was very engaging, even with the limitation of the course being pre-recorded.

I am very satisfied with what I learned despite not completing all assignments - I was interested in an experience similar to The Great Courses. Assignments and quizzes were a secondary consideration to me.

All in all, I highly recommend this course.

Fascinating, well put together, with a great professor. I'm sad it's finished and I want more! I've always loved theoretical physics, astronomy, space and the dimension of time so I couldn't believe my luck when I discovered this course title. Chris Impey didn't disappoint. Even though I sadly followed a different education route due to my perceived inability to master maths at no point did I feel out of my depths. This course is manageable for anyone with a passion to explore time and space. If you are thinking about signing up, make it so!

Night sky amazed me since I was a 5-year-old girl. Ever since I read and study anything related to astronomy whenever I get a chance. Even though I wanted to end up as an astronomer, I ended up as an IT professional. but you never know right? Some dreams never die! Anyway, This course is one of the best that I have come across and it was an honor to meet the brilliant professor Impey even through the course. Thank you so much for this amazing course professor and you are the best! I hope our paths will come across again through another course!

Very good course. Professor is extremely knowledgable. The course went over extra detail then I expected to be covered, so I was pleasantly surprised with how much I was able to learn about our understanding of the universe. The course is very good for understanding a broad plethora of topics related to astronomy and astrophysics. The only change I might make is in making more clear how dated some of the research is the explains the course content. Many times, it was tough to tell if what was being taught was the most current knowledge or not.

Dear Professor Chris Impey and Christy Reed!

Since childhood I have been fond of astronomy. Astronomy is everything for me. I have taken several courses to study this science. But my favorite course was your course. Of course, I am very happy to learn from Professor Chris Impey. Thank you for taking the time to teach us astronomy lovers. Thanks for creating this course. Thanks for organizing online discussions. Thanks also to our mentor Christie Reed. It helps students a lot.

Thanks again!

Brilliant course, really interesting. Professor Chris Impey has clearly put a great deal of thought and work into it and is a fantastic lecturer - very easy to listen to (which is important when you are feeling tired after a day at work!). The regular, live youtube sessions were an unexpected bonus and more than I would have ever expected for a course that was to all intents and purposes free. Thank you so much, not least for maintaining my interest through a busy summer and getting me to the end (many before have failed!).

Step by step learning from the basic to advance knowlege on the subject. The reading material and quiz and assignments all are useful in strengthen the understanding of the subjecs. I really enjoyed the assignments especially ones using tools such as galaxy zoo, micro observatory. These tools expand the horizon of what I learned from the course and get a glimpse on the current study of the interesting ongoing subjects such as exoplanets. 5-stars to course instructor and his team for regular discussions on various subjects.

This was a highly enjoyable and informative course. My one suggestion would be to add in time estimates for what it would take to actually read the accompanying textbook supplemental materials, as doing so would greatly enhance what is learned from the course videos. I would like go back and read those, because I definitely did not have the time to do so during most weeks. However, I found the estimates to be pretty accurate for simply viewing the course lectures, taking the quizzes, and completing the writing assignments.

Phew, 11 week time isn't short. It was challenging I won't lie. BUT at the end of the day throughout, there was satisfaction. This course is beautifully laid out giving you a truly mesmerizing journey but on top of all that was professor Impey's enthusiasm that made this material come to life. I thank him and his team who have been working all these years for online sessions and forums to give their learners a colourful experience throughout. AND I bet everyone taking this course that you'll be amazed.

Happy learning☺️

Pf. Chris Impey is an amazing teacher who explains almost everything you ever wanted to know about astronomy and space in general. This course covered things beyond what I expected, from the scientific method to the possibility of aliens in space and everything in between. In addition to that, the professor himself takes some of his time to answer any questions you have through his one hour live sessions on youtube. I highly recommend taking this course if you are interested in all things space.

Prof. Chris Impey has very well helped me in learning this course in fact I'm a curious astronomy aspirant. His teachings and explanations helped me to know very well in detail of the astronomy in each aspect and i personally thank my professor sir Chris Impey for helping me and completing this course with many newly developed skills your teachings helped me in developing my enthusiastic knowledge over astronomy more. And i further look into your live sessions. Thank you sir and to the team :-)

Great course, material is great and extensive. Recommended for people who have some interest but not a lot of knowledge in astronomy and would like to get a wide view of the field. One thing noting, although it doesn't take away from the overall experience, is that it is a bit outdated, as it was made in 2013-2014. It wouldn't take much to update the lecture slides letting students know the current state of things. Once again, it's not a big deal, and you should research online anyway. 5/5.

Today I completed this amazing Astronomy course in 2 month. Initially I try to complete the course within 1 month but as the course going on my mind didn't ready to accept all the theories like string theory, 10th dimension, Brane, Drake, Big Bang drawback, expansion of universe at speed more than light, exoplanets like earth and many more.

During the study, headache occurr in mind, but I tried to learn all these.

Thankyou Coursera, Prof. Imphey & Christy Mam for this wonderful journey.

El curso me ha parecido muy interesante ya que me apasiona la astronomía y opino que el enfoque ha sido muy completo, he podido tener una visión muy amplia de todos los aspectos de esta ciencia.

Me parece muy interesante también el matiz práctico de algunos temas como el "zoo galáctico" y el microobservatory.

En cuanto a las tareas calificadas por compañeros", me he llevado alguna pequeña decepción porque me he preparado a conciencia las cuestiones y esperaba algo más de nota.

Even though human life scale is negligible small as compared to our universe, our intelligence is what will cover the gap. And courses like these not only inspire us to research but also motivates us that we still have a long road to achieve greatness and this might not be achieved by fighting and talking on this pale blue dot. I am very much pleased by your content Prof. Chris . Hope you keep on making such content and our search for our better selves will continue beyond.

Thank you Professor Impey, this course has opened my eyes to astronomy and I am so glad that I completed this course this year, on my last year of high school, so that I can take astronomy besides physics at university. If it hadn't been for this course, I wouldn't have considered it, but now I'm in love with astronomy and can't wait to study it in the future. The course was wonderfully taught and I also loved the little songs throughout. Great course, thank you so much.

This course is a perfect beginners guide to astronomy. It's simple enough to follow yet detailed enough to give you a real sense of the field. The video lectures and readings are interesting and well organised in week by week topics. The assignments are challenging without being too time consuming. Professor Impey holds live YouTube question and answer sessions almost monthly, giving you direct access to him.

I found this course engaging, satisfying and truly educational.

This was a brilliant course to truly know about astronomy and to know about the secrets of space. The division of course into 11 weeks and these different categories provides a detailed approach to every topic included in the course. This course covers every topic related to astronomy. The photographic PDF files provided before every week is a very good thing to provide to a student as they change the point of view of the student to looks at the aspects of Sciences.

I really enjoyed taking this astronomy course. Although I always had a profound interest in astronomy, I haven't had the time or the resources to amplify it until I came up with this online course in coursera. The themes explored were vast but all of them were studied in the most detailed view possible. I particularly enjoyed week 10 and 11, since were confronted back then with the most profound questions of our existence. I thank you all who made this possible !

This course was extremely interesting and informative, from the very first week till the very last. The insertion of relevant clips and images during video lectures, as well as the pace of course delivery was spot-on. The instructor is extremely knowledgeable and I learnt a lot about astronomy from the course. The difficulty was not high either, as very little prerequisite information was required in the course.

Highly recommended for all astronomy enthusiasts.

It was an excellent course for full 11 weeks. Lot of information were fed to us continuously each week. I will definitely go through various articles and videos online. With basic knowledge on various fronts of astronomy, I will be able to comprehend as well as appreciate the difficulties astronomers go through each day. I have come to know what infinite space-time is.

Thank you Chris and your videos were amazing and the presentation could not have been better.
