Our Milky Way Galaxy has satellite galaxies, and some of those galaxies might have their own smaller satellite galaxies. Now researchers have figured out that distant galaxies around the Milky Way impose stronger restrictions on the link between the size and structure of galaxies and the dark matter halos that enclose them. Moreover, researchers have also discovered more hints of the presence of LMC satellite galaxies. If findings would be correct, our galaxy should have an extra 150 or more very faint satellite galaxies awaiting discovery by future space projects.
