[Science & Tech] Einstein Ring

What is Einstein Ring?
Einstein Ring is a deformation/distortion of a light from a source (like a star or galaxy) into a ring by the bending of the light rays (gravitational lensing) from the source due to a massive galaxy or a back hole known as the lens.
Gravitational Lensing
The bending of light by a gravitational body is known as Gravitational Lensing. It was first predicted by Einstein in 1912.
