This is true.
I will take note of it.
And for full disclosure, I do not personally recall having seen these areas of the moon before... ;)
There is no permanent “dark side” of the Moon. The Moon does have day and night, just like Earth — every part of it receives sunlight. What is true is that the Moon is tidally locked to Earth, so we always see the same face. That’s why people often (incorrectly) call the far side the “dark side.”
