This graphic from the Hubble site illustrates how a distant quasar's light is altered by a massive foreground galaxy and by dark matter.
The galaxy's gravity warps and magnifies the quasar's light, producing four distorted images of the quasar.
Dark matter clumps in the path alter the apparent brightness and position of each quasar image as shown by the wiggly lines in the graphic.
Gravitational lensing was first predicted by Einstein.
