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.

The star Betelgeuse is about 425 light-years away If it explodes tonight what would happen?
I would like to explain that in fact, Betelgeuse is closer to 640 light-years away than it is to 425 ly. So, if it goes supernova tonight, the light from this massive explosion would take 640 years to get to Earth. So, we would observe this supernova only 640 years after it has actually happened.
