So I hear a few universities now offer PhDs in astrobiology. I would love to be an astrobiologist, especially if it meant analyzing data from NASA probes! But, seriously, aside from the handful of jobs offered by NASA, do astrobiology careers even exist? I know that PhDs in general are risky, and that many science PhDs spend years in postdoc limbo. I am willing to take a risk if it is for something I truly love. But would an astrobio PhD be merely a risk, or would it be career suicide?
