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.

A binary star system passed within one light year of our solar system only 70,000 years ago. It may have jostled a bunch of comets out of their orbits at the time.
Did a close pass by an alien star system millennia ago rain down comets on the solar system?
St. Patrick’s Day Moon & Jupiter on Flickr.
Yesterday I looked at the moon and Jupiter and thought, there’s going to be another conjunction tomorrow, isn’t there? Then I forgot, but fortunately I had to make a grocery run.
I took this photo just minutes ago. If you’re in the western half of North America, and the sky is clear, you can walk outside RIGHT NOW and see this.
