Is the far side of the Moon always dark?

Verdict
False
Verification confidenceHigh

Explanation

No. The Moon's far side receives sunlight. It is called the far side because it faces away from Earth, not because it stays in darkness. Like the near side, it experiences daylight and night.

NASA's DSCOVR spacecraft photographed the illuminated far side in July 2015. Royal Museums Greenwich explains that the Moon rotates at the same rate as it orbits Earth, keeping roughly the same face toward us while sunlight moves across its surface.

Some deep craters near the lunar poles contain permanently shadowed areas. Those localized shadows are different from an entire hemisphere being dark. The useful distinction is between the near and far sides, which describe our viewpoint, and day and night, which describe illumination.

Key takeaway

The Moon's far side is hidden from our usual view, not from sunlight. Permanent darkness occurs in specific shadowed areas, not across the whole far side.

Evidence

A spacecraft photographed the illuminated far side

NASA Earth Observatory

Contradicts the claim

DSCOVR's EPIC camera captured the sunlit far side of the Moon passing in front of Earth on July 16, 2015.

Based on: NASA Earth Observatory

Synchronous rotation does not prevent daylight

Royal Museums Greenwich

Contradicts the claim

The museum explains why the same lunar face points toward Earth and states that lunar daylight and night each last about two weeks.

Permanent shadows are localized

Provides context

Deep craters near the Moon's poles contain permanently shadowed regions. These do not constitute a permanently dark hemisphere.
