I'm half confused. Light source - the sun, just take it when the moon is in it's new moon phase (side facing earth is dark, side facing sun is light).
But the moon is tidally locked to earth, we always see the same side, so what is taking the photo?
Artemis II visited while the far side was dark, so I guess this is an old tweet otherwise why would NASA be releasing it now?
Happy to be told I'm dumb if I got something wrong...
What is visible isn't actually the far side, they're less than 90 degrees around to the "left."
This feature circled in red is called Grimaldi crater:
It is visible from the Earth; here is the view of the Moon you're probably used to seeing with Grimaldi again circled in red:
Well I am a step closer to the answer. Here a similar photo taken on the Artemis II mission with the same identifying features: https://images.nasa.gov/details/art002e009212
Long story short, like 3/4 of what is in this photo is the near side of the moon.
As a side note, the coloured image on the left of the OP appears to be this image that reddit detectives have decided was edited by OP. No one has found that coloured version on any NASA release.
