This video was made from 400,000 photos of Comet 67p taken by Rosetta

PetaPixel:

From 2014 to 2016, the European Space Agency’s Rosetta spacecraft followed the comet Churyumov-Gerasimenko (67p) around space: collecting scientific data, sending a probe to its surface, and capturing some 400,000 photographs of the comet. This cinematic video was made from those photos.

If you had told me this video was the opening sequence to the next Alien movie, I would have believed you.
