There was a time when astronomy was only a component of astrology, and astrophysics/cosmology is what happened when science-minded astrologers figured out the whole thing couldn't work because their attempts to make ever more accurate "predictions" (soothsaying) based on ever more accurate predictions (of the positions of celestial bodies) told them the universe was arranged just a little bit differently than they'd supposed. What is now purely pseudoscience was once a proto-science; the woo was still woo, but there was actual science there as well.
