“Why do pictures taken in space have no stars in the background”

“Scientists predict the light levels that a camera will encounter through its mission, and design their instruments to have an aperture that’s an appropriate size for the range of targets they expect to encounter. This can be a challenge if your spacecraft will encounter a wide range of target brightnesses, but you make your camera to work on the intended science targets”


“Many photos of spacecraft or astronauts in space don’t show stars because the camera settings required to capture such brightly lit foreground objects are different than the settings required to capture distant and much dimmer stars.”


“All of the photos captured on the lunar surface were taken with the Astronaut’s chest mounted camera at a shutter speed of 1/250th of a second. This was because the bright sunlight was hitting the lunar surface with no filtration by an atmosphere and reflecting off the light colored terrain, Apollo hardware and Astronauts suits etc. Stars on the other hand, are extremely dim and would require a shutter speed of anywhere between 10 seconds to 30 seconds. So at a mere 1/250th of a second no stars will be captured.”


“The stars are there and the astronauts can see them if they look away from the sun. The reason that the stars do not show up on the film is that the stars are so dim that the camera cannot gather enough of their light in a short exposure. Our eyes are a lot more sensitive to light than photographic film.”
