If you're a Battlestar Galactica fan, then here's something you'll need to navigate the colonies: a star map of the Colonial systems created by BSG writer and co-executive producer Jane Espenson and science advisor Kevin Grazier!
OOOoooo, can I get a "frak yeah!" from the flight deck?
That's pretty cool. And given that Kevin has a degree in astrophysics and works on the Cassini Saturn probe, one assumes he knows his stuff. Heck, I know he does: we've been friends for a few years now. The link above goes to the sci-fi blog io9 which has an interview with Kevin and Jane about the map, too. And if you like it, you can order a 27" x 29" poster of it from Quantum Mechanix.
