A descriptive overview of astronomy with particular emphasis on observation. Lectures will cover the solar system, the Earth-Moon system, stellar systems, celestial motion, the history of visual astronomy, optical aids, and observing techniques. This course is not intended to be part of a physical science premajor.
Course Outcomes
Upon successful completion of the course, students should be able to demonstrate the following knowledge or skills:
- Identify constellations, stars, planets, and other objects;
- Demonstrate familiarity with the construct of the dynamic celestial sphere;
- Demonstrate the ability to use a planisphere and star chart;
- Demonstrate understanding of basic properties of light;
- Demonstrate understanding of fundamentals of human vision as they apply to astronomical observation;
- Demonstrate understanding of atmospheric conditions, including light pollution, pertinent to visual astronomy;
- Demonstrate the ability to use binoculars and telescopes to view astronomical objects;
- Demonstrate understanding of properties of telescopes including magnification, light-gathering power, and resolving power;
- Demonstrate understanding of moon phases and surface features;
- Demonstrate understanding of solar observation technique;
- Acquire basic familiarity with solar features;
- Research celestial objects and locate them in the sky;
- Demonstrate understanding of universal, standard, daylight, local and sidereal times; demonstrate understanding of eclipses.
