The distinctive pattern of bright highlands and dark lunar maria on the moon has been turned towards us for millennia, visible to every human who has ever stood on earth Learn about tidal locking and its fascinating effects. But why do we only see this one side of the moon
We know that earth spins about its axis, so why don’t we get to see the full lunar surface as our moon does the same? Here's why we always see the same side of the moon, and why there's no dark side of the moon The reason for this similarity is simple
So, what about the other surface of our only natural satellite? During the new moon phase as viewed from earth, the far side is fully illuminated The more accurate term is the “far side,” referring only to the hemisphere we cannot see from earth. The observation that the moon consistently displays the same face to earth is one of the most fundamental facts in astronomy
This phenomenon meant that roughly half of the moon’s surface remained unknown until the space age, when probes could finally orbit our natural satellite The hemisphere we see is called the near side, while the one permanently turned away is the far side This means that although the moon is rotating, it always keeps one face toward us Known as “synchronous rotation,” this is why we only ever see the moon’s nearside from earth.
And at new moon, the moon is on the opposite side of its orbit from when it was full
