The Galaxy continues to give in to the gravity and continues to collapse into a disk with a bulge in the center. The beautiful spiral arms are formed due to a gravitational instibility of the matter in the galaxy. These instibilities are called density waves. These waves cause the stars and matter in the galaxy to build up and slow down as they are orbiting. And because they are crammed so close together it triggers a massive star burst of new, hot, bright stars that don't live very long.
Star formations continue all through out the galaxies life.
The circle of life continues and stars die as well. Elliptical Galaxies Elliptical galaxies form in a more coincidental manner. In my opinion I think that elliptical galaxies are much more beautiful than spiral galaxies. They are just simple and plain looking. Elliptical galaxies are formed after two spiral galaxies have collided.
