Webb4 aug. 2024 · This would be extraordinary. Therefore, quite a lot of very high-quality evidence is required before the claims of astrology could possibly be accepted. The lack of such evidence, even after millennia of research, indicates that the field is not a science but rather a pseudoscience. Observational astronomy is a division of the astronomical science that is concerned with recording and interpreting data, in contrast with theoretical astrophysics, which is mainly concerned with finding out the measurable implications of physical models. It is the practice of observing celestial objects by using telescopes and other astronomical apparatus.
