COSMIC MESSAGE
This isn't a galaxy with four nuclei, but a trick of gravity. The Einstein Cross shows light from a distant quasar bent and split into four images by the gravitational field of a foreground galaxy. This cosmic mirage only happens when the quasar is precisely aligned behind the galaxy's center.
