  1. Question

    What advice would you give a high schooler who wants to be an astrobiologist? Would you take a biology or physics major when applying to colleges?

    Since astrobiology is a multidisciplinary field, the best college training would involve studying both a physical science (such as geology or chemistry) and a biological science. Please see the “career paths” note on this page for details.
