Ok basically from what I understood. If we look throught a telescope at say saturn. We arnt looking at the Saturn of now we are looking at the Saturn from 30 mins ago.
Basically light takes time to reach different destiations. It takes 7-8 mins to reach earth. Then it takes 30 mins to go from earth to Saturn. So if you look through a telescope and see saturn its not the Saturn from now its the Saturn from 30 mins ago. Because the light is hitting Saturn reflecting off. When we look through a telescope and see saturn its light up because the suns rays are reflecting off of it and those reflections take 30 mins to get back to us.
This is the way I percieved it when they went into detail. Is the way I percieved it correct?
This is why we can take the hubol telescope look at distent stars and see what happened near the big bang. They said they have been able to look back and see up to 700 million years after the big bang. Because distent stars lights are just hitting us but those stars lights took billions and billions of years to reach earth.
And how we have new stars in the sky but we cant see them yet because there light hasnt hit us yet. Or how some stars have died out but we can still see them because there light is still traveling to earth.
Now am I correct or did I percieve this wrong?

). So if it reflected off of Saturn 30 minutes ago, you are indeed seeing Saturn as it was 30 minutes ago.
