You bet! When we get an image of a star or whatever that is 1 billion light years away, we are receiving photons emitted 1 billion years ago, and we are getting a picture of what it looked like 1 billion years ago. We have _no idea_ what it actually looks like today because the photos emitted today aren’t going to arrive for another billion years. Every picture we have of anything in space is a picture from the distant past.

We can’t! We can only see things that where the light has had enough time to reach us. There is an edge to the observable universe, where the universe simply isn’t old enough for the light to have had time to reach us. We have _no idea_ what is beyond the edge of the observable universe.
