The effect you speak of occurs when the bright objects light is diffused by the atmosphere
surrounding the point of view. Windows act in much
the same way as the atmosphere in this respect. We all know that looking out a window at night is much easier when you turn the lights off. Think of
Earth as the room with the window. During the day, sunlight is reflected by the surface, illuminating the room. At night, there's no light to be
reflected by the "window" (atmosphere), enabling you to see through the "window".
When viewing from a location with no atmosphere, stars should be visible, even if the sun is within the field of view. In photographs however,
exposure must be considered as well. With the sun in the field of view, especially from a vantage point with no atmosphere, exposure must be minimal
to avoid overexposure. As exposure time drops, so will the number of stars that can be seen in the resulting photographs.
The thinker in me tells me this is why so many NASA photos don't have stars in them.
The CT in me tells me it's because they're photo-chopped out (then the thinker asks why on earth would they want to hide stars).
The fantasy driven CT in me tells me that it's because they're not hiding the stars
, they're hiding the atmospheres
