The Einstein Cross Gravitational Lens

COSMIC MESSAGE

This isn't a galaxy with four nuclei. It's a quasar, a very distant and bright object, whose light is bent by the gravity of a foreground galaxy. The galaxy acts like a lens, splitting the quasar's light into four distinct images. This phenomenon is called a gravitational lens, or an Einstein Cross.
