Our Milky Way galaxy and its neighbor, the Andromeda galaxy, seem to be going through a midlife crisis. New research reveals that both galaxies are in the middle of transitioning from young, star-forming regions into older, stagnant ones, a transition that is revealed by the galaxies' color. Generally, such a change comes after two galaxies collide, astronomers said, but this pair seems to be making the shift on its own. In galaxies, star formation rates and color are closely related. But, analyses of the shade of the Milky Way are surprisingly rare. A team of Australian astronomers, led by Simon Mutch, of the Swinburne University of Technology in Melbourne, sought to determine the color the Milky Way and the nearby spiral Andromeda galaxy.
