Milky Way Transit Authority

Samuel Arbesman is a researcher at Harvard Medical School, and an amateur astral transportation cartographer... His interest in astronomy and transit maps has led him to create this fanciful Milky Way Transit Authority map:

Our galaxy is unimaginably vast, and we really have no idea what is out there. We are discovering new planets in other star systems all the time, learning new facts about the galactic core, and even learning about whole new portions of the galaxy. This map is an attempt to approach our galaxy with a bit more familiarity than usual and get people thinking about long-term possibilities in outer space. Hopefully it can provide as a useful shorthand for our place in the Milky Way, the 'important' sights, and make inconceivable distances a bit less daunting.

Arbesman's page also includes links to several other idea-based transit maps, some that I hadn't seen before, such as modern music and creative and important people in history.
