Actually, now that you point it out, do you happen to know why there are no stars visible?

Is it day on the moon on that picture or whats the cause? O.o

Stars are dim. Earth and the Moon are bright. If you exposed the shot such that stars would be visible, the Earth and the Moon would be horrendously overexposed.

If you look at this one of the moonlit nightside of the Earth they took on the way out, you can see stars. The website has EXIF-data on the bottom with more info on the exposure.

To save people a click: ISO is 51200 (in layman’s terms: holy shit it goes this high?) and they still exposed for 1/4s (somewhat normal for low-light photography) at an aperture of f/2.8 (gaping hole).

Holy shit what a picture that is. I always think of Sagan's pale blue dot speech when I see stuff like this. Perspective is a funny thing.

Just the light contrast. Stars are not as bright as the light from the sun reflecting off the Earth and the Moon. If they adjusted the exposure enough to see the stars, the Earth and Moon would look blindingly bright in comparison.

It truly needs to be very dark for stars to be easily visible, to the extent that the mere lights from a nearby city shining through the atmosphere are enough to render them invisible on a clear night.

That was quite qiick and well worded. Thank you!
