The relentless pull of the Earth's gravity on the Moon causes it to always point the same side towards us. The Moon's slight wobble has allowed us to catch glimpses of a small sliver of the Moon's far side. In 1968 the first humans to see the far side with their own eyes were the astronauts of Apollo 8. Perhaps someday humans will put a base on the far side of the Moon where powerful telescopes would be unaffected by light and electronic noise from Earth.
