It looks like the course website I created for my "Alien Worlds on Earth" mini-course is not globally viewable like I hoped it would be. The course went well, and I do hope to do something more with it in the future. In the mean time, I wanted to share some of the resources I gathered to share with students who wanted to know more about the environments we were talking about in class. I hope these are interesting and useful... let me know if they are!
