# Stars/Courses

The course objective is to provide students with information about stars. At the end of the course, a student should have a well-rounded knowledge of stars, astronomy, radiation, and observational and theoretical astronomy, each as they apply to stellar radiation sources in the sky especially at night.
The course is built upon the ongoing research performed by astronomers around the world and in the not so empty space above the Earth's atmosphere.
In line with the Wikiversity ideal of learning by doing are sixteen laboratory opportunities, an equal number of problem sets at several levels, and participatory lessons. To present a wide variety of concepts within stars, there are some forty-eight lectures which are also partly articles as references from the scholarly literature are included to challenge the student and open doors to further curiosity.
Within the stars/course are several others, including Solar astronomy and those you put together to learn by doing!

## Prerequisites

A working knowledge of calculus and physics is beneficial. Most concepts presented require only an understanding of algebra. Additional learning resources are also provided through the course to increase a student's background knowledge.
