I really enjoyed working through the modules of this course. The material was interesting and enlightening. The self-paced format worked well for me and I will look for similar courses going forward.

This course is bad!

I had come upto week 4. While Chris Impey is knowledgeable and good, the course structure is very poor and leaves a lot to be desired. I would venture to make some suggestions:

a. Restrict each video to a max of 7 minutes. More than that makes one sleepy.

b. Reduce the number of videos in each module to a max of say 6.

c. Instead of having Chris expound it like an audio reading, please include some slides, pictures,tables so that the matter to be learnt becomes self evident and Chris doesn't have to speak so much. A good example is the Coursera "The Global Financial Crisis", which I am also doing currently.

d. If you feel all the material in this course has to be studied, then to achieve the objectives in (a) and (b) above, divide this course into two parts, Astronomy: Exploring Time and Space - part I & II.

e. The written assignments are very simple and do not require any mental resources other than memory. Can you make the questions more challenging? For example, in Telescopes (Assignment 2), can you not ask a question like "In addition to Atacama, Chile, using Google earth, which other parts of the globe may be suitable for installation of ground based telescopes?" or "To obviate the blurring effect of the atmosphere, discuss the possibility of high altitude balloon based telescopes?" or "What do you feel about the fact that since today's mobile phones have high computing ability, their components can be used to make a low-cost space based interferometric telescopes?"

Kudos to Chris and his team! On the whole, knowledge wise, this is a good course.

Curso incrível. Pude compreender desde conceitos básicos em física e metodologia em ciência pra poder facilitar o entendimento de conceitos mais amplos e o estudo de objetos astronômicos como formação de sistemas solares, galáxias, o próprio universo e mesmo outras áreas como biologia e suas possibilidades.

Astonishing course. It taught me since basic concepts in physics and scientific method so it could facilitate the understanding of bigger concepts and the study of astronomical objects as the formation of solar systems, galaxies, the universe and even other subjects as biology and its possibilities

Extraordinary course covering all the basics of astronomy from it’s history to current day, and future exploration. This course has invigorated my enthusiasm for astronomy and the universe and provided me with a good foundational knowledge of the cosmos. Now whenever I see an article about astronomy I know what they’re talking about!

On a side note - the english subtitles could use some work. I liked watching the videos with subtitles but found often that there was a mismatch between what was said and what was written.

You may end up with more questions than answers, but hey, welcome to the Universe. This course is awesome and will nurture your hunger for astronomical understanding, bringing you right up to the cliff's edge of our knowledge as a species. It's terrifying and exhilarating and a mental roller coaster rich in information that would happily sit on my shelf next to the Cosmos series.

This Online course became the KEY FACTOR IN choosing between Stony Brook University and University of Arizona. Not just my love for Astronomy skyrocketed but also the stuffs I learned were really helpful in buying a telescope, impressing my friends with the constellation and detection of planets in the sky and going a little ahead from my highschool courses to my college life

Not only this course took me on a voyage of the universe but with that, we have explored so many different subjects entangled with this very course itself. We have learned physics like never before and exploited the science from it's very core. Not to mention the history of astronomy, the world, the galaxy and the universe and the philosophical message as well. best course!!

Shame editing was poorly done. Whoever did it thought that it must be waste of viewers time to wait until Chris takes breath for next sentence. Not only that we had no time for recollection thoughts, it also makes his head constantly jerking. Very unnatural and unpleasant experience. Other than that course is highly recommended. Chris is 5 star guy.

Astronomy: Exploring Time and Space opened a whole new world of the excting field of Astronomy for me. Even a person with no prior knowledge can learn the basics of Astronomy here. Dr. Chris Impey has presented a wonderfully lucid and exhaustive narrative of the curious cosmos through this course.

This course gives insight to basic of astronomy, astrophysics and cosmology and help us to understand the universe as we know today. It increases our interest in the subject due to which studying the universe becomes our life-long learning goal.

I've had amazing journey in learning much about astronomy. The course content was amazing, the teacher and mentor were very helpful and answered each and every query. There is much more to learn from the Discussion Forums.

An excellent course, I really enjoyed it. I suggest anyone even mildly interested in astronomy take it, whether you're a 10th grader or a college student. Fantastic job by Professor Impey.
