This survey only covers the part of the sky where the Milky Way galaxy itself is thickest in the bottom image above you can see the edge-on disk of our galaxy plainly stretching across the entire shot and thats only a fraction of the entire sky. Think on this: there are a billion stars in that image alone, but thats less than 1% of the total number of stars in our galaxy! As deep and broad as this amazing picture is, its a tiny slice of our local Universe.
