VIDEO | 4K Earth Images Taken from ISS

by

Timelapse video made from photographs taken at a rate of one every second. ESA astronaut Alexander Gerst from the Expedition 40 crew took the photographs onboard the international space station. The video is offered in Ultra High Definition or 4K. The artistic effects of the light trails from stars and cities at night are created by superimposing the individual images and fading them out slowly. Credit: ESA
