NASA provides its own space-based headlines as well. With such resources available, information about the latest scientific discoveries is easily found, and further research can lead to a greater understanding of the context of the discoveries, and of how science is done. The topics-driven astronomy course is not a new idea. Dan Caton of Appalachian State University has tried a non-linear approach, driven by astronomy in the news, for several years.

Numerous textbooks are available for either preference, and some are available in both formats.
The instructor must be willing to react to topics and research them as they come up. Once this background is established, we are ready to dive into the infinite possibilities the universe presents.

Particular classes meet regularly in most of these rooms, and other classes can reserve limited use of them.
