Excellent course. Very clear lectures that cover a lot of ground in not a lot of time. Fantastic overview of most of what we know about astronomy and how we know it. Best class I've taken on Coursera.

The is the first time I have rated a course with 5 stars, but this one is worth it. I audited and did not take the exams, but I thoroughly enjoyed the lectures and I learned a lot.
