I’m not sure if I worded my question correctly, but let me try to explain more.
If we use a giant telescope to look at another planet 10 light years away from us, we would be looking at how it was 10 years ago. The thing I don’t understand is how does light store and also transfer all the information about that planet (or all the “data” that ends up in our eyes) and yet it’s still the fastest thing.

When you look at something far away with a telescope, it works the same way as when you look at something nearby with your eyes. The only difference is that the light had farther to go, and the telescope has to be bigger to collect more of it.
So the light carries the same type of information your eyes get, which is just the color (wavelength) of the thing and the direction the light came from. The telescope focuses it back into an image of the thing.
