I​ LOVED this course, so I am going to continue with other astronomy courses online. Thank you Professor Impey for your amazing lectures. You kept them at a hide threshold which was great.

Great course covering many interesting aspects of astronomy and astrobiology! However it could use a few updates - for example, it's mentioning gravity waves as something yet to be detected.

I'd planned only to audit it but it's been better than expected, it's explained clear but it allows critical and scientific thinking.
