How do telescopes that are made up of several somethings miles apart work?

Question

I’ve seen talk of using the moon or even telescopes all over the world collectively work as a single telescope.

Answer 1

We have two eyes. Amd if you close each eye, you’ll notice that they give *slightly* different pictures.

By combining these pictures, we can get a composite image that contains a lot more information. In our case, the differences between what each eye sees allows us to gauge distance.

Same deal with telescopes. By combining the images that each telescope sees, we can see things that each individual telescope on its own cannot.
