In this week’s Nature Fabio Governato and colleagues present computer simulations that appear to have solved a long-standing problem in cosmology — namely, how the standard cold dark matter model of galaxy formation can give rise to the dwarf galaxies we see around us.

This beautiful animation shows how exploding stars are a key force in shaping dwarf galaxies.
