This is a week long event that happened recently called AbSciCon 2015 and which NASA Astrobiology recorded. The different speakers covered an immense variety of topics inclusive within the realm of Astrobiolgy free for you to choose to view whenever and in which ever order you like
Wow, thanks for sharing!!
You are welcome. These videos can be seen on many platforms. I've used Windows and more recently, Adobe Connect on Android, though I've heard its also viewable on Apple
