This course covers all basic elements of astronomy and cosmology. The Professor is great and the lectures are very clear and effective. No math skills or previous knowledge of the topic is required.

An important limitation, however, is that much of the material is outdated. Some videos were recorded as far back as 2010! In the sciences everything changes fast, and a few years can make a big difference. I think the year the lectures were recorded should be indicated in the course’s info page, so that learners know this in advance.

The staff is great and the mentor always answers readily and kindly on forums.

The contents of the course are great and prof. Impey is a great communicator. The course is easy to follow, the final chapters on galaxies and cosmology are a bit more difficult but that is due to the nature of the subject and I applaud that the prof does not "dumb it down" or brushes over such difficult ans speculative subjects. I minor nuisance for me were the frequent songs and funny videos interspersed in the course content. It would have been better if they were separate from the main videos or otherwise could be easily skipped by people who don't have a lot of time. overall a great course!

The course is great, videos and material are excellent, professor and mentors are very helpful. The assignments grading scheme, therefore is a disaster. It is very frustrating to do an assignment and get bad grades from people who didn't had any effort to do it. They simply spam bad grades over the others, and when you see their submission is always plagiarized content from Wikipedia, Space.com, Forbes or any other website. Because of that I will not give 5 stars. It would be 5 if mentors or the professor evaluated the assignments.

Course was excellent. Prof. was excellent. I am a retired nurse so I took the course because of my lifelong interest in astronomy, science and the unknown. My only complaint is that I could not complete the last quiz because I could not get the micro-observatory to work on my Mac OS. My husband is a computer engineer and he could not get it to work on his computer either. This was disappointing!

I've always been fascinated about space and astronomy and there are so many questions that come in my mind and at times there are certain questions that you never ask yourself because you have too little knowledge and this course has given me the answers to all my questions and has increased my curiosity about the the world out there and thus inspired me to learn even more about the universe.

Really enjoyable course. Fascinating subject matter.

Some course materials could do with being brought up to date with the latest developments.

But then the pace of progress is breathtaking. As a beginner, I have learned a great deal and will continue more in-depth learning via the many excellent internet facilities.

Thanks to Professor Impey and Arizona University.

There should be some improvement in the course , the course name is astronomy:exploring space & time so according to me the course should have included topics related to time-travel , 3d space, 4d space , einsteins theories . But besides that the professor was very knowledgeable and videos he included in his lecture were really interesting.

A very informative course for begineers. I personally find this course a very informative. This course provides me information about some areas of astronomy which i don't even know before. Moreover, this course increases my interest in Astrophysics. In the end, a big THANKS to professor Chris impey who taught it so well.

Pretty good, some of the units drag on a little but most of the content is very interesting and the instructional videos include very funny videos or videos from pop-culture, which makes some of them very entertaining. I feel like I have definitely broadened by knowledge by taking a chance on this comprehensive course.

The course is very good and I liked the prof. My only complaint is that the lectures themselves and the videos within them are becoming a bit dated. My knowledge in astronomy was not extensive coming into the course and I feel like now I have a better understanding of the expanse of the field.

Coherent and related to subject matter. Materials are linked and presentation is good. Text is well writing and congruent. Some material is quite outdated but not antiquated. Unable to effectively use http://archive.stsci.edu/hst/hsc/ versions 3 ,2 or 1 yet. May be insufficient OS or browser.

Very interesting, well presented. I do prefer the format of The Moons couse on futurelearn however, found it hard to stay awake watching videos even though they are interesting. I think having to scroll and open links on the futurelearn site is enough to keep me awake and engaged.

It was one of the best course i have undertaken in Coursera. Prof. Chuck is a very knowledgable person. Enjoyed a lot along with learning. Very interesting course. Although if there could have been some updates on the recent findings in the field, it would have been more awesome.

I have been fascinated with Astronomy since childhood. In the Boy Scouts, I had learned a lot when I received my Starman badge. This course gave me more of an insight into the heavens and I am grateful to the University of Arizona to let me take this course free of charge.

I loved learn with him. The informations are easy to understand and the switch between slides and videos is just a great idea. I just ask to instore the 1-point-notation, when we review our peers. I recommend this course to everyone who is interesting by astronomy!!

I found this course a great introduction to Astronomy. Unfortunately some fo the content is out-of date but it is easy to find the more recent information on these areas generally on the internet. I have recommended this course to others and they are enjoying it.

It is a very comprehensive course and the professor speaks a good English what make easier to follow the lessons. The materials used are quite good and I am enjoining it.

Have completed a survey about course under the name TITAN

The course is really interesting. The space always fascinates me a lot, and I have obtained much knowledge about our solar system, the Milky way, and the universe. Ready for more advanced courses in this area:)

This Course is very much informative, but you have to keep in mind that the completion(certification) of this course might take huge time even months as there might not be any peer to review your assignment.

Excellent and complete course where i learnt a lot with passion. I met problems with some links, but in general is fantastic. I got more fascinating knowledge but more question to keep learning.

This course need more polishing by some feasible experiments. Sometime we get wander from the crux. Overall topics and in-depth demonstration by Professor Chris Impey is quite mesmerizing.

A good introduction to some of the more difficult aspects of astronomy and astrophysics for a person that wants a top level overview of string theory and the creation of the universe.

The course is excellent and gives us an idea how astronomical studies are and how it is divided and organised. It is absolutely opt for who want to start their career in astronomy

A really good course to get an overview of the topic and the Professor is quite good too. This is an easy course to recommend, for interest or certificate.

The course for beginner who want to know about basic in sciene and astronomy. You will understand the phenomena of our world, our galaxy and the universe.
