Astrology was studied in university (in Italy) until the 17th century; afterwards, the Inquisition and the Roman Catholic Church put an end to its development. That’s because divination would have been an obstacle to God’s universal action, which is why nature and planets could no more acting as a connection between man and God.

Astronomy and astrology have kept a common path for a long time since; astrologers hailed Copernicus’ De Revolutionibus enthusiastically because of the simplification brought about to astrological calculations. But with the approaching ‘Age of Enlightenment, reference books and encyclopaedias started to report the difference cleanly between astrologia naturalis, dealing with the scientific investigation of natural phenomena, and astrologia giudiziaria (judicial astrology), the art of forecasting events through planets and their relationship to the Earth. From that starting time, astrology became a superstition and was overshadowed by astronomy in academic studies.
Nowadays, scientific thinking is based upon an objective analysis of things as they are (or seem to be) through a theoretical statement giving some validity to the facts or experimental observations (or both). On the other hand, astrology takes into account the interaction between the phenomenon and the observer. From an astrological point of view, the whole universe and our awareness join in the same process; that’s why we can’t tell that there is a planetary influence, as some people suggest. Relatively speaking, planets and stars exist separately from our consciousness and, as such, are subject to scientific investigation. Conversely, astrology undermines the assumption that the physical world exists independently of our observations (as some thinking on quantum mechanics suggest, for instance). Consequently, astrological factors act like a symbolic mirroring of the reality we belong to, so our nature becomes highly readable via these same symbols.
Is reunification a possibility? Whether we want to or not, it is to be hoped that the scientific paradigm based upon quantum mechanics opens a window on a new era of cooperation in years to come.
