Journey Through the Universe

2. Describe the place of astrology in science. How did the development of astrology follow or parallel the development of astronomy? What do you think were some causes for them to split or diverge?

3. Constellations are "just dot to dot" drawings. Why do you believe the ancient people took so much time to describe the stars as people and animals? Give some reasoning as it relates to different cultures.

4. How does the appearance of the sky change during the night? What accounts for the changes in appearance?

5. Describe the shapes of the planetary orbits in each of the solar system models that have been proposed. Why did these orbital shapes change from model to model?

Astrology and astronomy are historically one and the same discipline (Latin: astrologia), and were only gradually recognized as separate in western 17th century philosophy (the "Age of Reason"). Historically, most cultures have not made a clear distinction between the two disciplines, lumping them both together as one. In ancient Babylonia, famed for its astrology, there were not separate roles for the astronomer as predictor of celestial phenomena, and the astrologer as their interpreter; both functions were performed by the same person. This overlap does not mean that astrology and astronomy were always regarded as one and the same. In ancient Greece, presocratic thinkers such as Anaximander, Xenophanes, Anaximenes, and Heraclides speculated about the nature and substance of the stars and planets. Astronomers such as Eudoxus (contemporary with Plato) observed planetary motions and cycles, and created a geocentric cosmological model that would be accepted by Aristotle -- this model generally lasted until Ptolemy, who added epicycles to explain certain motions. However, around 250 B.C., Aristarchus of Samos postulated a proto-heliocentric theory, which would not be reconsidered for nearly two millennia (Copernicus), as Aristotle's geocentric model was favored.
The primary goal of astronomy is to understand the physics of the universe. Astrologers use astronomical calculations for the positions of celestial bodies along the ecliptic and attempt to correlate celestial events (astrological aspects, sign positions) with earthly events and human affairs. Astronomers consistently use the scientific method, naturalistic presuppositions and abstract mathematical reasoning to investigate or explain phenomena in the universe. Astrologers use mystical/religious reasoning as well as traditional folklore, symbolism and superstition blended with mathematical predictions to explain phenomena in the universe. The scientific method is not consistently used by astrologers.
Astrologers practice their discipline geocentricically and they consider the universe to be harmonious, changeless and static, while astronomers believe that the universe is without a center and is dynamic, expanding outward.
Astrology and astronomy stayed together for a very long time - the funding from astrology supported some astronomical research, which was in turn used to make more accurate ephemerides for use in astrology. In Medieval Europe the word Astronomia was often used to encompass both disciplines as this included the study of astronomy and astrology jointly and without a real distinction; this was one of the original Seven Liberal Arts. Kings and other rulers generally employed court astrologers to aid them in the decision making in their kingdoms, thereby funding astronomical research. University medical students was taught astrology as it was generally used in medical practice.
