Uhhhh, the map of our galaxy has been redrawn many times in the last 50 years. Did you know(really talking to everyone else I'd imagine) that our galaxy is really a barred spiral galaxy?
But it really lloks something like this with a single straight "bar" going thru the center of hte galaxy - http://zebu.uoregon.edu/~soper/ImGalaxies/m83.gif
What kind of stupid dupes do you think we are? Every body knows about Milky Way bars. Ummmm.
