To understand X-ray astronomy, it is necessary to talk about light and how it works. The Imagine the Universe! website hosted at NASA's Goddard Space Flight Center has a great tutorial about the electromagnetic spectrum, and how astronomers are just now starting to see the Universe in its full range of colors. The pages listed below are just a sample of the information at that wonderful site.
