It looks like a scene out of Game of Thrones - an icy wall of rock towers over a boulder-strewn plain, as a blizzard coats the land in snow.
But not all is as it seems. The location isn't Westeros, it's a comet - and it's not snow that fills the skies, it's stars.
Twitter user Landru79 took a series of still images shot by the Rosetta space probe from orbit around the comet 67P/ChuryumovGerasimenko, and turned them into a short clip that's taken the internet by storm.
The second-long black-and-white video actually covers 25 minutes of real-time. The snowflakes are actually stars that appear to be moving across the sky thanks to 67P's rotation, and the streaks are believed to be dust particles illuminated by the sun. The flashes of light are cosmic rays.
Each still is the result of a 12.5-second exposure shot from orbit, about 13km away.
Landru79 says a full-colour version of the clip is on the way, once he's combined the images with colour information Rosetta beamed back.
They posted a second animation of the same images but with the stars in place, emphasising the comet's movement and rotation.
All the images are publicly available. The ones in this clip were shot in June 2016, before the probe was deliberately crashed into the duck-shaped comet, ending the successful 12-year mission.
