“The moon has a 'dark side' that never sees the sun.”

The idea that the Moon possesses a perpetually shadowed "dark side" is a widespread misunderstanding. In reality, every portion of the Moon's surface experiences sunlight. This common misconception stems from the fact that the Moon is tidally locked with Earth, meaning it rotates on its axis at the same rate it orbits our planet. This unique dance ensures that only one hemisphere, known as the "near side," is ever visible from Earth.

Due to this tidal locking, the hemisphere we never see from Earth is referred to as the "far side." For centuries, before the advent of space exploration, this far side remained a complete mystery to humanity. Its unseen nature contributed to the popular belief that it was a place of perpetual darkness, simply because it was perpetually out of our sight. The first images of the far side were only captured by the Soviet Luna 3 spacecraft in 1959, revealing a heavily cratered landscape, not an eternally dark one.

Therefore, the term "dark side" is a misnomer that actually refers to the "far side" – the hemisphere that consistently faces away from Earth. While this side was historically unknown to us, it receives just as much sunlight as the near side. As the Moon orbits the Earth and rotates, sunlight continuously illuminates different parts of its surface, creating lunar day and night cycles across both hemispheres, much like our own planet.
