Polar Auroras in High-Definition ISS Time Lapse Video

A German astronaut has captured stunning images of polar auroras as he orbited Earth on the International Space Station. Alexander Gerst’s images led to the creation of the Ultra-HD – or ‘4K’ timelapse video, running at 25 frames per second.

The photographs were taken at a resolution of 4,256 x 2,832 pixels and depict Gerst’s orbit around the Earth alongside his fellow ISS Space Station expedition 40 crewmembers.

His journey shows the rippling greenish lights characteristic of the electrically-charged sun particle collisions, bright city lights in the nighttime, the different hues of the Earth’s atmosphere and a satellite launch.
