Are we alone? This course introduces core concepts in astronomy, biology, and planetary science that enable the student to speculate scientifically about this profound question and invent their own solar systems. All the features of this course are available for free. It does not offer a certificate upon completion....

The best course ever.! it really has the scientific detail that you do not find anywhere else in a clear simple and didactic way. The instructor is an amazing educator.

Thorough, lengthy, weeks-long grounding in the subject. Only problem is stupid peer review.

Sorry Professor David>>>your presentation on the 'dark streaks' on Mars' crater sides is outdated. I personally have studied these some 10 years ago having followed the 3 rovers and the lander 10 years ago and watched the water sublimate from the Phoenix digs, at that point I knew 'instinctively' that the dark lines were sand. Please see NASA link above.

I can not continue your course for the obvious reason that some other data will be outdated.

However, I truly have enjoyed your presentation method and if and when your updates to other lectures are complete I will endeavor to complete the lecture course.

Thank you.

Really enjoyed the course. It gave a very comprehensive introduction to Astrobiology and I enjoyed being pushed to write a science fictional short story at the end.

"Imagining Other Earths" introduces one to astonishing aspects of planetary science, delivered expertly by David Spergel, Charles Young Professor of Astronomy on the Class of 1897 Foundation and Chair. I found the course to be invaluable in improving my understanding of the universe in which we live. Professor Spergels unassuming, inimitable style of delivery leads one to an easy understanding of complex concepts. I found the Professor and the scientists who spoke with him in interviews which supported the lectures to be inspiring. I commend this course to anyone who is interested in understanding the universe.

This class was an exceptional journey into the world outside our own - and the details, balance, and intricacies of an ever changing universe. Professor Spergel is an incredible asset to the world of astrophysics and I feel truly lucky that he took the time to teach us. I happily anticipate leaning even more on this fascinating subject.

This is simply fantastic! Such a charismatic lecturer leading us so professionally through heavy subjects in a light manner! Looking forward to more courses!

This is a wonderful course, even for somebody, such as myself, who tends to freeze in terror when presented with mathematical equations of any sort. I'm a linguist, artist and musician, so no physicist, and yet have found here a wealth of imagination and knowledge that is accessible, even if only at the broadest level, to anyone, regardless of their academic background. Highly recommended.

This was my first coarse on Coursera, and it is an amazing coarse. The professor and the presentation are so vividly unique, even as a high school sophomore, I was able to understand a large part of it.
