"Why the Milky Way May Be Facing a Midlife Crisis"

Does this mean it will want a really big Corvette, then?
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.


But the Milky Way and the Andromeda galaxy are shifting from blue to red without a collision, which was a surprising discovery, the researchers explained.

Since they are already slowing down, when they crash into each other in the future, the collision most likely won't generate a new powerhouse.

"When" they crash into each other. Folks, our galaxy is doomed. But don't lose any sleep over it. It won't be for another five billion years or so. Plenty of time to engineer a new empire.
