Gravitational Lens Forms Giant Arc

About this image

This illustration shows how an image of a background galaxy is distorted and magnified by the gravitational field of a foreground galaxy. In this alignment gravity acts as a lens in space by warping space like a funhouse mirror. The image of a distant galaxy is stretched into a giant arc.
