Come June I will have my masters from a top uni in the field of astrophysics (though most of my thesis work was in statistics). I'm looking for jobs just about anywhere but I've heard good things about civilian military research. How does one get into doing research in something like particle or plasma physics or even observational astronomy with the military? Do they only go for phds or do they hire fresh masters grads? Should I be looking at non-military labs instead (eg pacific northwest national lab)?
