In the past three years, fourteen Milky Way satellite galaxies have been discovered, more than doubling the known population. These newly discovered "ultra-faint" galaxies have emerged as the least luminous and most dark matter-dominated galaxies in the known Universe. They are dramatically reshaping our understanding of galaxy formation and may hold the keys to deciphering the nature of dark matter. Professor Marla Geha reviewed our current understanding of the ultra-faint galaxies, focusing on the constraints these objects provide on dark matter.
