Why are there no stars in space photos?

The video explains why stars are often not visible in space images. It discusses how both human eyes and cameras adjust to bright light, affecting star visibility. The Apollo astronauts experienced this on the moon, where the sun's reflection made stars hard to see. Similarly, cameras on spacecraft use quick shutter speeds for daytime images, missing background stars. However, longer exposures can capture stars. Space agencies often release mosaics of images, which exclude stars to enhance resolution and reduce data transmission needs. This approach is crucial due to limited bandwidth in space.
