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.

The course in general is very interesting and anyone who's even slightly intrigued by Astronomy and the universe we live in will find it very satisfying. The video lectures were great, and supplementary materials were in abundance.

However, some of the material was quiet hard to understand, especially for non-native English speakers like me. I'd improve the accompanying subtitles for the video lectures (some of them were actually misleading).

Some of the lectures included animations, simulations and external footages that really helped understanding some of the complexed materials - more of these would have been great (they were indeed missing sometimes).

Also, the later subjects were more interesting than the first ones, and though I understand the importance of understanding the basics before diving into the "deep water", I'd make the first classes more brief (history of astronomy, the scientific method), and extend the later subjects (astrobiology, distant galaxies, the Solar System planets and moons, etc.)

Overall, I had really great time, and I definetely recommend this course to anyone :)

The course content, material, delivery, and (some) reference material are great. There is A LOT of progressively complex information to be absorbed and professor Impey does a great job as a guide through this journey. Sadly, links to some reference material are not up-to-date (notably, podcasts episodes). Assignments have a good balance of complexity and work well to reinforce knowledge.

I specially liked the last section where we delve into philosophical takes on our place in the universe and what we have learned and the concept and undertanding of life and wish it was expanded. By the same token, perhaps this course needs to be broken down intro intro, mid, and advanced level ones to be more effective.

El curso es muy bueno en general pero adolece de información astronómica actualizada, falta que agreguen los últimos avances de esta ciencia de al menos 4 años para acá, cosa que en estos tiempos implica un gran atraso. Asimismo los videos que incluyen algunas clases de prof. Impey son muy malos, con baja definición y calidad.The course is very good in general but it lacks up-to-date astronomical information, it is necessary to add the latest advances in this science from at least 4 years to now, which in these times implies a great delay. Also the videos that include some classes of prof. Impey are very bad, with low definition and quality.

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!

While I did find the course very interesting and informational, I was under the impression that most of the information would be about up to date astronomy findings, but the professor often spoke of things that happened at least 7 years ago. He spoke of how exciting the mars curiosity rover landing would be and what information it might send back, but that happened in 2012, and since then the perseverance rover has been launched and Opportunity died. Apart from this I greatly enjoyed the course, and have been bombarding my parents with cool new astronomy facts I've learned.
