While we're talking about galaxies (TESB and otherwise), one interesting little statistic for you... If the Sun were one pixel on a jpg image, that jpg would have to be 25,000km wide to show the whole galaxy. Even at one pixel, the galaxy is still twice the diameter of the Earth. Jinkies!

I think the galaxy debate is exhausted anyway... if it were meant to be a galaxy it doesn't matter anyway as it's irrelevant to the plot. If you want to see it changed, cool, but it makes no difference either way.
