Free Harvard astrobiology course

[Stratis]

So I've been told via Facebook buddies that Harvard University are offering a free online introductory astrobiology / exoplanetary science course, due to start in the middle of October. You can pay for some sort of verified certification ($49) but you can audit the class for free. That's what I'm doing, I'm more interested in the knowledge than fridge decorations 

Here's the edX link if you're intrigued : http://bit.ly/1KSwjop

Thought it might be the sort of thing this crowd might be interested in, if you know any other forum members who might have some time on their hands an an interest in this sort of frontier science then just send them the post link, as it'll drop off the front page I suspect.

Clear skies everyone!
