Did you see the video on how the picture was generated? The picture shows a composite of pics taken at the center of sphere. As if you could put a rotating, spinning camera in the inside of a beach ball and have it take pictures of the inside of the ball. Then open the sphere to show the shape you see.
It's not that the satellite has left the Universe, turned around and took the picture.
It boggles the mind, but there isn't even a nothingness outside the universe. Space itself is supposed to be self-contained, and limited. Sort of like the earth, limited area, but no edge to fall off of. Space, limited volume, but no "edge" to nothingness.
