Rendering of a simulation that follows the formation of the first galaxies in the universe. The field of view is adjusted to account for the expansion of the Universe, where the scale bar represents 32,600 light-years (10,000 parsecs). The video shows hot and ionized gas in blue, and cold and neutral gas in red. The intensity of the pixels are set by the gas density, and the stars are not shown in this visualization. The video lapses from 200 million to 800 million years after the Big Bang.
