Dwarf Galaxies Like the Magellanic Clouds Have Their Own Small Satellite Galaxies

Dwarf galaxies like this one (NGC 5477) are satellites of larger galaxies like the Milky Way. New research examined 36 distant dwarf galaxies to see if they had their own, smaller satellites. The goal is a better understanding of how galaxies form and evolve in the Lambda Cold Dark Matter paradigm. Image Credit: ESA/Hubble & NASA

Massive galaxies like the Milky Way have smaller satellite galaxies that are tidally disrupted and absorbed. Astronomers think this is how galaxies assemble hierarchically. New research examines galaxies much less massive than the Milky Way to see if they also have their own, much less massive satellites.
