Look at this comet's terrifically chaotic surface

Landru79 created this spectacular GIF from images captured in 2016 on the surface of Comet 67P/ChuryumovGerasimenko by the European Space Agency lander Philae deployed by the Rosetta probe. The video is significantly sped up, compressing 25 minutes into a few seconds of intense action. But what exactly are we looking at in this pandemonium? From New Scientist:

Much of this apparent snow wouldnt actually be visible if you were standing on 67Ps surface. It is made of cosmic rays charged subatomic particles that flit across the universe. As they hit the cameras sensors, they register as streaks of light.

Some of bright specks are actually snow dust and ice particles floating above the comets surface. And many of them are stars behind the rocky cliffside on 67Ps surface.
