what trips me out is when I zoom in on that picture I see what looks like film grain , and then I realize that a lot of that probably isn't film grain and is really more galaxies, further away and dimmer so they appear that way.... the large scale structure of space is like some sort of foam, or sponge like.... we're just this incredibly tiny peice of that. we find what we do here at home on earth, so I'd be willing to bet that what you will find out there might be almost anything.....there's everything out there.
