We get this question a lot when we share astronauts’ pictures on social media: “Why can’t you see any stars in the photos astronauts take from space?”
The fact that there are no visible stars in photos and videos from the moon landing has also fueled some conspiracy theorists’ suspicions, though NASA scientists explain that “the camera was unable to capture the light emitted from the stars because the bright sunlight hitting the moon’s surface washes out the light from the stars.”
That same bright light is the reason many astronauts’ photos from the International Space Station appear to show space as pitch black and void of stars, write experts at PhysLink.com:
“The reason why no or very little stars can be seen is because of the Earth. The Earth, when lit by the Sun, is many thousands times brighter than the stars around it. As a result the Earth is so bright that it swamps out most if not all of the stars.”
“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.”So American astronaut Reid Wiseman’s latest space snapshot, taken with a longer exposure, shows that, yes, of course there are stars in space:
