Airglow

Airglow is the faint shining of the night sky that is present anywhere in the world. It is caused by the energetic sunlight ionising high altitude oxygen molecules. During the night they recombine and cause a faint glow which is brightest near the horizon. More information can be found on Atmospheric Optics by Les Cowley.
