Diffusion can e.g. make the moon appearing sometimes larger, sometimes smaller (depending on the angle). The longer the way of light through the atmosphere, the more diffusion, the larger the moon appearing. Same with stars: Without atmosphere they are ultra-tiny lightpoints, too small that you can see them on a space camera. Reason why the ultra-tiny lightpoints are larger from earths surface is the same: diffusion makes them larger. |

Space believer User ID: 72627101 Canada 07/21/2016 12:59 AM Report Abusive Post Report Copyright Violation | The stars are not visible in most photographs taken from ISS because of a combination of ISO, aperture setting, and shutter speed. Stars can be photographed on either the sunlit side, or the night side of earth from the ISS, but the exposure must be set for the dim light of stars. To our eyes, once adjusted to the darkness of night, stars seem somewhat bright, but next to a mobile phone screen on its dimmest setting, it becomes apparent how dim stars actually are. In some photos of earth taken from the night side, stars are visible, but often the photo is framed to focus on the earth as the stars visible from the ISS are the same as the ones we see from here. |
