Most astronomy positions require a Ph.D. in the field of astronomy, which usually takes 5-7 years to complete. These programs are likely to contain courses in astrophysics, stellar and planetary physics, galaxies, cosmology, interstellar medium and optics. Mathematics and computer science are also emphasized. After completing a Ph.D. program, aspiring astronomers often enter one or more postdoctoral research positions, which can take roughly 2-3 years to complete.
