The Vera C. Rubin Observatory has begun to film the greatest time-lapse movie ever made: a 10-year record of the changing night sky. Over a few nights, the telescope will sweep the entire hemisphere of sky visible from its Chilean mountaintop with the largest digital camera ever built, then do it again and again for a decade. In its first year the survey will generate more data than all previous optical telescopes combined. It will capture everything from wandering asteroids and exploding stars to the growth of distant galaxies, and it will spew the data continuously to the world’s astronomers.
