Airglow And An Aurora

The International Space Station was orbiting 264 miles above the North Atlantic when this photograph was taken of an aurora streaming above the Earth's horizon.

The Earth's airglow, an optical phenomenon caused by cosmic rays striking the upper atmosphere, blankets the horizon.
