In astronomy, seeing is the degradation of the image of an astronomical object due to turbulence in the atmosphere of Earth that may become visible as blurring, twinkling or variable distortion. The origin of this effect is rapidly changing variations of the optical refractive index along the light path from the object to the detector.
Early photos of Earth taken from space have inspired a mild version of the overview effect in earthbound viewers. [1] The images became prominent symbols of environmental concern and have been credited for raising the public's consciousness about the fragility of Earth and expanding concern for long-term survival on a finite planet.

Airglow over Auvergne, France Yellow, green and red bands of airglow along Earth's limb as seen from space. Airglow (also called nightglow ) is a faint emission of light by a planetary atmosphere . In the case of Earth's atmosphere , this optical phenomenon causes the night sky never to be completely dark, even after the effects of starlight ...
Pale Blue Dot is a photograph of Earth taken on February 14, 1990, by the Voyager 1 space probe from an unprecedented distance of approximately 6 billion kilometers (3.7 billion miles, 40.5 AU), as part of that day's Family Portrait series of images of the Solar System.
