 | | Astronomy is not to be confused with astrology, which assumes that people's destiny and human affairs in general are correlated to the apparent positions of astronomical objects in the sky -- although the two fields share a common origin, they are quite different; astronomers embrace the scientific method, while astrologers do not. |
 | | Although most astronomers incorporate elements of both into their research, because of the different skills involved, most professional astronomers tend to specialize in one or the other. |
 | | In the late 10th century, a huge observatory was built near Tehran, Persia (now Iran), by the astronomer al-Khujandi, who observed a series of meridian transitss of the Sun, which allowed him to calculate the obliquity of the ecliptic. |
