Movie of a computer simulation modeling the merger of two galaxies. The remnant galaxy is similar to our neighboring Andromeda galaxy. Debris of the collision are expelled in long tidal tails, along which tidal dwarf galaxies form. These orbit in a common plane, because they follow the motion of the tidal tail. This might explain the satellite galaxy planes around the Milky Way and Andromeda.
