About this course: Learn about the science behind the current exploration of the solar system in this free class. Use principles from physics, chemistry, biology, and geology to understand the latest from Mars, comprehend the outer solar system, ponder planets outside our solar system, and search for habitability in our neighborhood and beyond. This course is generally taught at an advanced level assuming a prior knowledge of undergraduate math and physics, but the majority of the concepts and lectures can be understood without these prerequisites. The quizzes and final exam are designed to make you think critically about the material you have learned rather than to simply make you memorize facts. The class is expected to be challenging but rewarding.

Ratings and Reviews
Fascinating subjects presented brilliantly by Mike Brown (and his two colleagues)
This has been my favuorite course so far! Really interesting and totally challenging.
This is a great course. I'm a regular guy with no science education, just a keen interest in science and astronomy. The lectures delivered by Mike Brown and guests are clear and high quality, so even I could follow along. The mid-lecture questions, weekly quizzes, and final exam are designed to make you think about what you have learned rather than just regurgitate facts - this really helped me with the learning process. I just need to learn how to take better lecture notes for future courses. Thank you to all involved for an excellent ten weeks :)
