On September 30, 2016, the Rosetta mission officially came to an end. It had orbited the comet 67/P Churyumov-Gerasimenko for two years, taking over 100,000 images of the comet's nucleus, some from quite a distance, some from mere meters away.
It revealed a bizarre landscape with sharp cliffs, huge boulders, pits where subsurface gas escaped, smoothed regions sculpted by the ethereally faint whisper of that same gas leaking out… and even, in one particularly gasp-worthy sequence, a dusty snowstorm from the comet that has to be seen to be believed.
In a moving and stunning tribute to this mission, artist and photographer Christian Stangl has made an incredible video, taking these images to create footage that is both stark and beautiful in a way that's hard to describe.
