Where can you study astrobiology?

Answer 1

Starfleet Academy?

The only places I'm aware of with a formal program in it are the NASA Astrobiology Institute at the NASA Ames Research Center (Mountain View, CA, US) and the University of Glamorgan in the UK.

However, it's a multidisciplinary research field. Most researchers active in it are technically in Biology, Chemistry, or Physics (or, if at their particular institution it's a separate department from Physics, Astronomy) departments. Geology, Molecular Biology, and Biochemistry are also possibilities.

The proper way to pursue advanced studies is to pick a researcher who's doing something you're interested in, and go wherever they are. The USUAL way to pursue advanced studies (hey, it's what I did) is to pick a school and then try to find a researcher there doing something interesting. The usual method tends to fall apart if you're interested in a particular, highly specialized field (e.g. astrobiology), because there may or may not be someone doing research in that field at the particular institution you've chosen (exceptions being the ones listed above). You could get really lucky and there are several, you could get less lucky and find only one, you might get even less lucky and find someone who's not currently doing it but is willing to start a new project along those lines, or (and unfortunately the most likely case) is that no one there is doing it or interested in doing it, or the one guy who is has no funding, or is just generally an unpleasant person to work for (yeah, they say work WITH, but trust me, FOR is usually more accurate).
