You have never seen the sky look quite like this.
In this video, the images are time-lapsed. But instead of each image being filmed separately, using special effects software, the images are stacked, one image adding to the next, creating a stretched-out star.
As Malin explains: This video was achieved by "stacking" image sequences provided by NASA from the crew at the International Space Station. These stacks create the star trails, but furthermore make interesting patterns visible.
For example lightning corridors within clouds, but they also show occasional satellite tracks (or iridium flashes) as well as meteors—patterns that interrupt the main star trails, and thus are immediately visible.
Also visible: light pollution on Earth, which actually looks incredibly cool with this photo effect.
