About This Image
This diagram illustrates how gravitational lensing by foreground galaxies influences the appearance of far more distant background galaxies. These far-off galaxies that might otherwise be invisible appear due to lensing effects. The plane at far left contains very distant, background galaxies. The middle plane represents foreground galaxies; their gravity amplifies the brightness of the background galaxies. The right plane shows how the field would look from Earth with the effects of gravitational lensing added.
