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 Some material is quite outdated but not antiquated.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 Unfortunately some fo the content is out-of date but it is easy to find the more recent information on these areas generally on the internet.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.

I deducted a star just because it becomes lengthy when one thing is repeated in a series of videos. Overall the content of this course is awesome and gives a clear view of all the disciplines in Astronomy from physics to biology.

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.

Good and clear explanations. At the end it became more difficult since filosophie was involved which for me opened my ey. Some 'slides' are old fashioned.

It was a very good experience and super experience to add p your knowledge, but I face a problems only while reviewing peers otherwise it is best.

Sometimes the videos are poorly edited, and the semi relevant videos last for much too long, but I learned a lot and it's a reallly good course!

Loved the course, Dr. Chris Impey is perspicuous in his lectures. Wish I had taken coursera classes when I was a student when I had more time.

Great course! Full of excellent explanations from Dr. Impey. It leaves you with the anxiety to keep learning about this amazing science.

Sometimes very repetitive, especially in the Teach Astronomy readings, but overall an interesting and informative course.

Very nice. Something to improve: mix quizes with videos and not all videos first and then the quizes

Good course inviting the scientific thought process to evolve instead of believing the old stories.

For someone that had never studied astronomy before this it was a little hard, but worth it.
