Gravitational lensing, the bending of light which travels near massive objects, can result in distortion, magnification, and even multiple images of the original light source. The closer the light travels to the massive object the stronger the lensing effect. The magnification that results from this process allows scientists to observe objects which would normally not be visible due to their distance and brightness.
