Welcome to Brain Stuff, a production of IHeartRadio.

Hey, Brain Stuff. Lauren Vogelbaum here. You've probably noticed that

0:42.0

when you look up at the moon, you always see the same features. You can see craters and patches of

0:48.5

lighter and darker areas. With a pair of binoculars or a telescope, you can make out even more detail. But no matter how you look at the moon, you're always seeing the same landscape. But the moon is a sphere. If we're only seeing one hemisphere, then what's on the other side. This is the so-called dark side of the moon, the side we never see because it always

1:16.9

For this reason, people also use the phrase the dark side of the moon to describe something

This side of the moon faces the cold, black, expansive space. What could be on this side of the moon?

1:57.7

since we only ever see that one hemisphere. And it's easy to misunderstand the cause of the faces of the moon that we see from Earth.

2:05.7

But mostly, this is a problem with terminology.

2:09.8

The descriptor dark side suggests that shadows perpetually cloak the surface of the side of the moon that faces away from us. It's fun to imagine a

2:19.9

dividing line between the light side and the dark side, but that's not how it works. While it is true

2:27.6

that some part of the moon is dark at any particular time, it's not always the same part. That's because,

like Earth, the moon rotates on its
