This was a fun course, and I'm glad that I took it, however I wish that we learned a bit more science, perhaps about what work is currently being done that might encourage us to go into the field. Or perhaps there isn't much that can be done at the moment, because we are only just getting the technology and telescopes to have the ability to do interesting things in this area. I think the next 20 years will be a very exciting time for astrobiology.
A perfect course for study of astrobiology and ET. It includes the basics of life evolution and sustainability, telescopes and methods for life detection, possible worlds with life.
Very helpful and good course
