'Absolutely spectacular': Artemis II crew see first glimpse of far side of Moon

Astronauts on the Artemis II mission are on the third day of their journey around the far side of the Moon.

I am curious. If it is on the far side, where does the light come from for the photos? Other stars?

The moon is tidally locked with the Earth, which means the same side always faces the Earth. So, for example, when the moon is between the Earth and the sun, the far side (from the perspective of Earth) would be fully illuminated by the sun.

The “far side” of the moon refers to the hemisphere that can’t be seen from Earth.

Yes, and right now is full moon, thus the far side is only illuminated by stars.
