I remember when that famous picture came out. I think it was at a meeting of the Astronomical Union. It's quite a simple concept. Space is so fast, the farther out you look with a telescopic device, the farther back in time you go. So, the pic that came back showed how the Universe looked 13 billion years ago, after it had started forming galaxies. That's confirmed by seeing some of them not fully formed yet.
Also, look how "close" to one another they are. The Universe hadn't expanded much yet.
