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.

Awesome! Completing this course gave me the ability to form my own opinions about developments of space exploration. I learned not just raw info about the solar system but also the methods the astronomers use in order to explore the universe and find out about its origins, going back billions of years ago. Just what I expected from this course.
