Summary

  Stars of our galaxy orbit its center in a disc that has more than 50 thousand light years radius.
  Originally it was thought that the disc is symmetrical.
  New research shows, that there are regions above and bellow the disc.
  Scientists don't know what is the cause of this asymmetry.
  Leading explanations are collision with another galaxy in distant past, gravitational influence of satellite galaxies, or influence of internal structures, for example arms of the Milky Way
