Introductory Astronomy on the Internet is a three-credit descriptive course, requiring no on-campus activities. The advantage of this course is that you have the freedom to work anytime you choose -- day or night, weekends and holidays -- and you may complete the requirements as quickly or slowly as allowed by your personal circumstances.

This course has been written for students who have little or no preparation in science and mathematics and who are most likely using it to fulfill their general educational requirements for a college degree. The authors have attempted to share their enthusiasms for the field of astronomy and to encourage students to become more involved in science.
