the milk way

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.
  •, free monthly star maps like those we distribute at the planetarium, more.
  • Bad Astronomy by Phil Plait, hosted at Slate. The best astro blog out there, in our opinion.

  • US Naval Observatory, Astronomical Applications. Sunrise, sunset times, and much more almanac data.

  • Astronomy Picture of the Day. Just what it sounds like, with an expert explanation. Great site.
  • Hubblesite. Public release images and everything else related to the Hubble Space Telescope.
  • NASA Eclipse Website. Wonderful and thorough site.
