We've seen "fly through the universe" video clips before, but this one is the best yet! Miguel Aragon, Mark Subbarao and Alex Szalay created this animation above from the most recent data from the Sloan Digital Sky Survey.
While you gawk at the clip, remember this: each "speck" you see is a galaxy containing billions of stars. There are about 400,000 galaxies in the animation - a small slice of the universe which is estimated to contain as many as 500 billion galaxies.
