Relax : Stars Collide
The sky is seen at night just before the predicted merger between our Milky Way galaxy and the neighboring Andromeda galaxy, in this NASA photo illustration released May 31, 2012. About 3.75 billion years from now, Andromeda's disk will fill the field of view and its gravity will begin to create tidal distortions in the Milky Way. The view is inspired by dynamical computer modelling of the future collision between the two galaxies. The two galaxies collide about 4 billion years from now and merge to form a single galaxy about 6 billion years from now.
