What Happens When Galaxies Collide? Hubble Space Telescope Finds New Surprises

The orbiting telescope also discovered a rotating, pinwheel-shaped disk at the center of the collision. In the Hubble photo, the disk resembles a full spiral galaxy, seen face on. Yet the disk is only ten thousand light-years across, about 1/20 the diameter of the whole galaxy.
