Gravitational Lensing Einstein Cross Of Quasar Bending Of Light

What is Gravitational Lensing ? Lensing Effect Of Gravity | Einstein's Ring Einstein's Cross
A gravitational lens is a distribution of matter (such as a cluster of galaxies) between a distant light source and an observer that is capable of bending the light from the source as the light travels toward the observer. This effect is known as gravitational lensing, and the amount of bending is one of the predictions of Albert Einstein's general theory of relativity.
This video explains how very distant galaxies are magnified through the phenomenon of gravitational lensing. Gravitational lenses can magnify the light from distant galaxies that are at or near the peak of star formation. This effect allows researchers to study the details of early galaxies too far away to be seen with even the most powerful space telescopes.
