You are looking at the past when you see sky. Always. Anyone on proxima Centauri will see earth as if was 4.5 light years ago. Betelgeuse might have already exploded. We are Andromeda as it was 4.5 millions year ago. Today Someone far away can see earth as dinosaurs are roaming. Time is relative.

Technically yes. That's what we are trying with jwst. Not the end of space but first galaxies and stars. Made of pure hydrogen. Right after dark ages.
