Night sky time lapse corrected to show earth moving rather than stars. Gorgeous.

Full screen, HD, you can thank me later.

“From the frame of reference of a human on earth, it can seem that the stars move across the night sky. In fact, it is just the rotation of the earth that constantly reveals new parts of the night sky.
By using software to track the stars and keep them still, the rotation of the earth is revealed.” More vids on Alex Rivest’s channel here.
