Ever wonder why stars don’t always show up in space photos? It’s all about how cameras handle light. Cameras can only capture a certain range between the brightest and darkest parts of a scene. Stars are very faint when compared to Earth, the Moon, or other planets. If the camera is set to properly capture the planetary body, the stars can be too dim to see. Cameras control light with three main settings: shutter speed (how long the camera’s sensor is exposed to light), ISO (the camera’s sensitivity to light), and aperture (how wide the lens opens). You can try to capture both stars and a bright planetary body in one shot, but it’s tricky. One will usually be a little too bright, too dark, or slightly blurry. In this image, both stars and Earth are visible, but Earth looks a bit blurry because the photographer used a longer shutter speed to bring out the stars, and the motion of the spacecraft caused Earth to blur.
