Show Notes
In today's image, we see two galaxies in the process of colliding together. When galaxies collide, their gravitational fields interact so that material is pulled out in streams as we see around the galaxy on the left. The process also takes a very long time - hundred of millions of years - so we only see a single snapshot of the collision.
