The two large densities are dark matter halos of the Milky Way and Andromeda galaxy; (B) Zoomed-in on the dark matter map, showing a small dark matter clump ~700 million years after the Big Bang; (C-1 and C-2) stars and gas in the simulated ultra-faint dwarf galaxy, formed in the centre of the small dark matter halo in panel B. The two panels show two different radiation levels shortly after the Big Bang. It reveals how the ultra-faint dwarf galaxy
