Why are deep space photos starless?

Hi All,
New to this site but APOD has been my opening screen for years. Love astronomy, the cosmos, the night sky, and learning new things.
Looking at the "Artemis 1: Flight Day 13" image today (12/01/2022), it reminded me of a question I have always pondered:
Why are there not millions of stars visible in the background?
Thanks!

Because most of these images are composed as daylight shots. Take your camera and shoot a daytime picture, then after dark shoot the sky with the same settings. You won't see any stars.
