Milky Way Expected to Survive a Beating

Milky Way Expected to Survive a Beating
This image from a supercomputer simulation shows the density of dark matter in our Milky Way galaxy, with yellow being densest and blue-black showing areas of least density. The bright central region corresponds roughly to the Milky Way's luminous matter of gas and stars, and the bright clumps outside indicate dark-matter satellites orbiting the Milky Way.
