A) It will collide with the Andromeda Galaxy,triggering new star birth in gas and dust clouds.
B) It will continue to move away from its near neighbor galaxy,M31 in Andromeda,allowing its spiral arms to straighten to form a central bar.
C) Its rate of rotation will slow and its spiral arms will dissipate into intergalactic space as the Galaxy becomes an elliptical galaxy.
