His six minute video is made up from 2,500 images that were taken from the space station over that time period. The photos included images of the Milky Way, the auroras, lightning and cities at night.

Gerst, who returned to Earth last month, also shared many of the images on Twitter over the last year during his time aboard the ISS.
