This animated flight through the universe shows close to 400,000 galaxies. Examples of galaxies range from dwarfs with as few as ten million (10^7) stars to giants with a hundred trillion (10^14) stars. In total there are probably more than 170 billion (1.7 × 10^11) galaxies in the observable universe… which is about 425,000 times more than the amount of galaxies show in this video.
