Do you expect that the student who asked the question would really get what we're discussing, here? I answered such that they could learn the basics and perhaps develop a desire to learn more. Heh.

Yes, the stars are very far away compared to their great distances. However, an optical phenomenon known as diffraction limits how well any telescope of a certain size can resolve tiny objects. It doesn't matter how big the image is made, diffraction limits the fine detail we can see. The only ways to increase the resolution is to simply make a bigger telescope or to make an array of telescopes and combine their images in a special way to increase the resolution. That technique is called optical interferometry. Lowell Observatory and the US Navy are working that. Here's the WikiPedia URL: http://en.wikipedia.org/wiki/Astronomical_interferometer You might want to check into that.
