All the upvotes! I am something of an astrobiologist myself, although my emphasis is on geobiology and planetary geology. My current day job is to map out Martian sedimentary rocks with an eye towards liquid water distribution and ancient habitability. My graduate thesis was closer to home, a study of Paleoarchean microbialites.
If you think your posts would benefit from a bit of collaboration, don't hesitate to ask. Otherwise, I'm eager to see what insights you have from a more astronomy-heavy and pure biology perspective.
Oh god please yes. I'm planning on talking about the limits of our observations in our own solar system and what is possible versus excluded both now and in the past, as well as origin of life research and the history of the scale and complexity of Earth's biosphere. Will PM you.
This is the first in a series of posts I am putting together on a personal blog I just started two days ago as a collection of my musings on astrobiology ("The Great A'Tuin" - sorry, I couldn't help it), and will be reposting here. Much has been written here about the Fermi paradox and the 'great filter'. It seems to me that going back to a somewhat more basic level of astronomy and astrobiology is extremely informative to these questions, and so this is what I will be doing. The bloggery is intended for a slightly more general audience than this site (hence much of the content of the introduction) but I think it will be of interest. Many of the points I will be making are ones I have touched on in previous comments here, but hope to explore in more detail.
This post references my first two posts - an introduction, and a discussion of our apparent position in space and time in the universe. The blog posts may be found at:
