How disorderly young galaxies grow up and mature

Using a supercomputer simulation, a research team has succeeded in following the development of a galaxy over a span of 13.8 billion years. The study shows how, due to interstellar frontal collisions, young and chaotic galaxies over time mature into spiral galaxies such as the Milky Way.
