Astronomy is the science that study stars, planets, galaxies and other thing that exist in the known universe. As a science it follows the same principles as other fields like chemistry or physics. Astrology is the theory that links certain behaviours or even prediction of the future based on the movements and the influences of the stars on our lifes. So, the difference is that one is a science field, the other is a theory.
