The Role of Galactic Collisions in Triggering Star Formation
Quick fact
Some colliding galaxies, like the Antennae Galaxies, are forming stars at a rate hundreds of times faster than normal spiral galaxies, producing brilliant blue star clusters.
Why this is interesting
You might expect that when galaxies collide, the stars themselves would crash into each other. But the real fireworks happen in the gas between them—turning galactic collisions into cosmic stellar nurseries.
