Motions of the 39 dwarf galaxies. In the background we show the image built from point sources in Gaia One can only see the brightest dwarf galaxies, and even theyy are barely visible. The galaxies are labeled with their names, and the arrows show the direction of their motions with respect to the Milky Way center. The color indicates the radial direction: those in blue are getting closer to the center, those in red farther. Credits: Gaia Data Processing and Analysis Consortium (DPAC); A.
