This is a flight through the neighbouring universe: this time you are not seeing the result of a simulation but you see the universe as it is. The data is from the Sloan Digital Sky Survey. You can see almost 400 000 galaxies in this video. Most of the galaxies in this video are represented by their real image, so this flythrough gives you an impression of what the universe really looks like. All the galaxies in this video are within a range of 1.3 billion light years from our Milky Way, so again we are just observing a small fraction of the entire visible universe (the 400 000 galaxies represent more or less 0,00025% of all galaxies in the observable universe, propably much less also considering the non observable part).
