As a result, the same side of the moon is always facing toward Earth, which we call the near side. The opposite side of the moon, which we call the far side or dark side, is not visible from Earth under normal circumstances.
One way to see the dark side of the moon is during a lunar eclipse. During a total lunar eclipse, the Earth passes between the moon and the sun, causing the moon to be briefly hidden from sunlight.
During this time, you can see the moon's silhouette and observe features on the far side that are normally not visible from Earth.
