The introductory material will be followed by a few weeks on the sky as it appears from Earth and how it is measured. We will consider the three basic coordinate systems used in astronomy and astrology, and we will also consider how the sky was measured by ancient peoples. The builders of Stonehenge and the ancient Maya were skywatchers and we will read most Anthony Aveni's book "Stairways to the Stars." Aveni, who teaches at Colgate, is a prolific writer on ancient astronomy and one of the major contributors to the field of archeoastronomy.
The next topic will be the Sun and the solar system. Using both Zeilik's text and a wonderful book on the planets by Michael Barich, we will explore first the Sun, then the inner planets, and then the outer planets. In this section, as there is really quite a lot of material, you will be offered a choice as to which of the planets you want to know the most about. Another topic considered in this section is the prospects for life on other planets or moons in our solar system.
There will be a number of live, online presentations this semester and once the class forms, we will establish a schedule. Questions by email may be asked at any time and I will respond within 24 hours.
Upon completion of the course you should have a solid foundation in astronomy and a much better understanding of how the subject developed historically and where it is today. You will understand the astronomy of ancient cultures and how astronomy is used in mapping the sky. You will learn much about current topics in solar system astronomy and you should also find articles on astronomy in magazines like Scientific American and Discover much easier to read and understand.
