Simulated distribution of galaxies at redshifts 9, 8, 5, 3, 2, and 1

Caption

These six cubes show the simulated distribution of galaxies at redshifts 9, 8, 5, 3, 2, and 1, with the corresponding cosmic ages shown. As the universe expands, the density of galaxies within each cube decreases, from more than half a million at top left to about 80 at lower right. Each cube is about 100 million light-years across. Galaxies assembled along vast strands of gas separated by large voids, a foam-like structure echoed in the present-day universe on large cosmic scales.
