The phases of the moon are easy to understand once you realise and remember that the phases are dependent upon the location of the sun, moon, and earth The phases occur because the sun lights different parts of the moon as the moon revolves around the earth. Explore the fundamental astronomical reasons why we always see the same face of the moon Understand this common celestial alignment. There's a swath of our natural satellite that always faces away from our planet The reason relates to the nature of the moon's movement.
All of the manned space missions to the moon have landed on the nearside due to communication needs, so humans have physically explored this side much more. Discover the science behind why we only see one side of the moon Learn about the moon's rotation, tidal locking, and more in this fascinating article. The simple answer (and one that you've probably heard before) is that we only see one side of the moon because the moon rotates around the earth at the exact same speed as it rotates around its own axis, so that the same side of the moon is constantly facing the surface of the earth This means that one full 'day' of the moon (meaning the length of time it takes for the moon to rotate. Over billions of years, the earth's gravity has forced the moon to spin synchronously with its orbit
Viewed from earth, the moon appears to rock slowly backwards and forwards so that we see a slightly different face throughout the lunar month There are two main reasons for this. 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 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? Tidal locking is the reason why we see only one side of the moon tidal locking is a phenomenon where the moon's rotational period matches its orbital period around earth
This synchronous rotation means that the same side of the moon is always facing earth while the other side remains hidden. The first time humans actually got a glimpse of the far side of the moon was in 1959, when the soviet spacecraft luna 3 beamed back the world's first images It was a pretty big moment, because we're so used to seeing the same side of the moon, day in, day out In the latest episode of.
