Now imagine looking at the Sun (do not actually look at the sun- this could potentially blind you). The light given off by the Sun travels further still- it takes about eight minutes to get to Earth, so when Earth-based telescopes look at the Sun, they're seeing it as it was a whole eight minutes ago. Put another way, something could happen on the surface of the Sun- a sunspot pops up, for example- and we wouldn't know about it for eight minutes.
