When you see a galaxy 8 billion light-years away you are looking how many years into the past?
When you see a galaxy that is 8 billion light years away, the light that's dribbling into your eye left that galaxy 8 billion years ago, and has been traveling toward you ever since then. If you just happen to see the galaxy explode or turn blue while you're watching it, you'll know that it actually exploded or turned blue 8 billion years ago. Similarly, if the galaxy explodes or turns green tonight, you won't know about that for another 8 billion years from tonight.
