... one of my fav sci fi shows is Battlestar Galactica. I just got the most recent series on DVD. Watching one of the first couple of episodes and there was a scene where there was a window in the background and I could quite clearly make out the constellation Orion in the stars out the window. If I could figure out how to take a screenshot of it I'd show you I'm not crazy.
Anyway, that tells me they must be close to finding Earth, at least within a galaxy or 2
