The nighttime view was made possible by the new satellite’s “day-night band” of the Visible Infrared Imaging Radiometer Suite. The new data was mapped over existing Blue Marble imagery of Earth to provide a realistic view of the planet. Sun doesnt wash away stars, but during night time without lit atmosfare we see clearly what space looks like.This image of North and South America at night is a composite assembled from data acquired by the Suomi NPP satellite in April and October 2012. We all know how light goes straight line from sun, and night is just shadow created by body of earth, and this means sky around horizon cant be in earths shadow. This means you are looking sky from surface of ball limited only horizon and you are from your point of view, middle of the night, at the "highest point' of that ball, earth precisely between you and sun. Since earth is "round" we can play with idea we are precisely middle of the night on middle of calm pacific ocean. Night sky we see is only partially shadowed by earth body, and space around that shadow is full of sun light, we just dont see it because there is nothing to reflect it to us.
There is another way to think this over when we are on earth during night we see sky as black, full of stars (depending on light pollution here on earth), but night for us, on dark side of earth, is illusion created by body of earth. Then it should be possible to take picture of all stars when you adjust settings right for stars and you are back against sun, earth and moon. There cant be light pollution which will effect taken pic. Same goes if you are on space walk, facing away from earth, moon and sun, there is nothing to reflect sun light since its empty vacuum. Sun might lit whole moon, but without atmosfare there cant be same light pollution we have on earth. However, if you take pic about sky from moon it shouldnt matter if its moons day or night. If you take on the moon sky will appear black.
When taking pics shooting parameters are adjusted to get best possible, or wanted, outcome to taken pic ISO, shutter speed, aperture. When looking sky during daytime our atmosfare makes sky blue, which means there is some matter what effects way we see sky and space.
