Via GOOD:
We’ve brought you the interstate highways as a subway map, and now here is the galaxy. In case you were confused how to get from here to, say Cygnus, this will help you out. Just take the red line to the blue line and hop on the express. For all the jokes, we know those stars are out there, but have no idea how they relate to each other spatially, and this goes a long way toward making the universe a little more understandable.
