Why Can't You See The Stars In Space? 5 Reasons

Since space agencies began sending astronauts into space, we've seen stunning photos of Earth, the Moon, and the International Space Station. However, we often notice that the images do not include the stars. Why? Shouldn't they look even brighter? Why don't photos taken in space include stars?
Let's find out!
Photographs taken from space can be disconcerting for many who expect to see the starry space that we fall in love with on Earth. Let's analyze the five most important factors contributing to missing stars in space photographs and the technological implications that this involves.

1. Intense sunlight: The main factor that prevents the stars from being seen in space photographs is intense sunlight. When the camera is set to capture the details of the foreground object, sunlight entering the camera can saturate the sensor and make the image appear too bright. This means that the fainter stars are not visible

2. Shutter Speed: Shutter speed is also an essential factor that affects your camera's ability to capture the stars. In most space photography, a fast shutter speed is used to prevent the image's blurring due to the spacecraft's movement.

3. ISO: The ISO is the camera sensor's sensitivity to light. The camera should be set to a low ISO sensitivity when taking pictures from space to capture starlight effectively.

4. Focal Length: Focal length is also essential to consider when taking space photos. Most cameras used in space have wide-angle lenses to capture a comprehensive view of space. However, this means that the stars appear smaller in the image. A longer focal length is required to get a more detailed image of the stars.

5. Image processing: Another critical factor affecting space photos' ability to show stars is image processing. Images captured by space cameras are typically processed to increase the contrast and clarity of foreground objects
