There are close to 400,000 galaxies in the animation, each containing between 100 billion and 400 billion stars. The images of the actual galaxies in these positions derived from the Sloan Digital Sky Survey (SDSS) Data Release 7. As vast as this slice of space seems, it only corresponds to a small fraction of the known universe. This animated flight was made by Miguel Aragon and Alex Szalay of Johns Hopkins University with Mark Subbarao of the Adler Planetarium.
