Milky Way and Andromeda held together by dark matter sheet

 Hey, Space Placers!

Milky Way: 2 close fuzzy blobs among green dots, with many short arrows pointing to them from above and below.

This is a simulated view of the Local Group of galaxies, which contains the Milky Way and the Andromeda Galaxy (the orange blobs). The pinkish-purple color illustrates an enormous sheet of dark matter, which a new study says is holding the Milky Way and Andromeda together, even while other nearby galaxies (the green dots) move away. The arrows show the direction and velocity of matter. Image via Ewoud Wempe et al./ University of Groningen.
