Astronomy is the scientific study of objects and phenomena beyond the earth's atmosphere by means other than visiting them or sending probes. The history of astronomy is the study of the development of astronomy from the earliest written records to somewhere very near the present time. Astrology is not astronomy, but it did play a role in the development of astronomy. Babylonian astrologers' determination of the positions of stars may be found here, their study of the effects of those positions on human affairs will not. The history of the scientific search for extra-terrestrial intelligence may be found here. UFOs visiting earth will not.
