It’s a cosmic winter wonderland. Comet 67P Churyumov-Gerasimenko is awash in what looks like snow in this series of images from the European Space Agency’s (ESA) Rosetta spacecraft.

The images were captured over the course of 25 minutes on 1 June 2016, and processed by twitter user @landru79.

Much of this apparent “snow” wouldn’t actually be visible if you were standing on 67P’s surface. It is made of cosmic rays – charged subatomic particles that flit across the universe. As they hit the camera’s sensors, they register as streaks of light.

Some of bright specks are actually snow – dust and ice particles floating above the comet’s surface. And many of them are stars behind the rocky cliffside on 67P’s surface.

ESA senior science advisor Mark McCaughrean that the stars in the background are in the direction of the constellation Canis Major.

The points that start at the top of the image and disappear beyond the horizon are stars and star clusters moving across the comet’s alien skies.
