In this section are links and other information that will help you learn more about astronomy. These only touch the surface, of course, but they are chosen with emphasis on helping you get out for some local stargazing.
- Gettysburg Skies, the blog of the Hatter Planetarium. Planetarium news and notes, follow-up resources for show topics, and sky events with a local slant.
