“Watch the universe unfold…in 1.5 minutes.” - The Atlantic
This video from the Sloan Digital Sky Survey is part of an ongoing project that will eventually capture images from over 1.5 million galaxies. Officially called “Data Release 9,” the map released by SDSS this week is the largest 3D map of the universe ever. From the Apache Point Observatory in New Mexico, SDSS has been using Apache Point’s telescope to survey the universe since 2000. The telescope captures images using drift scanning–also known as time-delay integration–which records images of single strips of the sky by taking advantage of the Earth’s rotation. So far, the project has generated data that accounts for some 7 billion years’ worth of cosmic movement.
