Obviously the proof would need to be verifiable by a university, or anybody else other than NASA.

There are no telescopes that powerful. However, when the astronauts were there they left reflectors that were carefully aligned towards Earth, so that we can shine a laser beam at them and see the reflection. By doing this and timing how long it takes the beam to travel back to Earth (traveling at the speed of light) we can calculate exactly how far away the Moon is. This is how we know that the Moon is actually moving farther away from Earth at a rate of about 4 cm per year.
