I am confused. How can we take pictures such as this of the distant cosmos. Would some damn planet or asteroid or rock not get in the way? It's like if I try to look really far with a telescope into the horizon, eventually I hit a tree or a building.

Is space really so empty that we can gaze million of lightyears and not have any obstruction of vision?
