Can you clarify? Aren’t we still observing an old state of any galaxy we see in the skies, simply due to the fact that light takes time to travel to us?

- planet-and-halo 6y agoI believe OP's point is that which state you're seeing varies by distance. We see Andromeda as it was millions of years ago, but we see other stars as they were "only" hundreds of thousands of years ago. Closer = more recent picture, Farther = older snapshot.
- Keysh 6y agoYes, exactly. (The Triangulum Galaxy, M33, can sometimes be seen; at ~ 3 million light years, it’s further away and thus an even older “snapshot” than Andromeda.)
