In many pictures taken from space, stars are not visible, even with a dark sky. The reason is that stars are very dim compared to the primary object in the pictures. If the camera is set to take a correctly exposed image of an object that is much brighter than the stars, then the stars would not be visible in the picture. The same thing would happen everywhere, in space, or on the surface of the Earth.
Flat-Earthers often take the lack of stars as fakery. They are wrong. This is simply a limitation of any camera.

How much of Earth we can see at once depends on our distance from the Earth. The closer we are to the surface of the Earth, then the smaller part of the Earth we can see at once. Conversely, the farther we are from the Earth, more of the Earth are visible to us.
The difference in the size of North America in these pictures relative to the size of the Earth is often presented as “evidence” that we have been lied to. In reality, it is simply a perspective effect. The pictures are taken from a different distance from the Earth and with a different camera field of view.

Ever seen a video where a flat-Earther tries to demonstrate that a distant object that appears to be behind an obstacle can be brought back into view simply by zooming in? He would then conclude the same thing would happen when zooming in to a distant ship, and the reason a distant ship is not visible is not the curvature of the Earth.
Well, no. The real reason why the object in that experiment can be seen after zooming in is that the obstacle is close, and there’s difference in the camera’s entrance pupil size when the zoom changes. For a camera that has very long zoom range —like the Nikon P900—, the difference can be very dramatic.

In some photographs of the Moon, there are bright spots in the dark part of the Moon. Some flat-earthers believe that these are ‘stars’, and the Moon is actually transparent.
These are in fact image noise, not stars.
