I love the fact that we can actually *use* gravitational lensing to see things in space even more distant than our telecopes can, almost as far out as the edge of the observable universe. (i.e. before things are too far for light to have reached us yet at all.)
And find surprises, like this early, early galaxy that looks like it had already started rotating 13.3 billion years ago.
