What Is the Farthest Thing We Can See?

Imagine you're looking at a flashlight in the dark. The farther away it is, the smaller and dimmer it looks. Now imagine that flashlight is actually a galaxy, and it's so far away, its light has been traveling for almost 14 billion years, since the beginning of time! That’s one way to think about what we can see, the farthest things are the ones whose light took the longest to reach us.
