Einstein Rings are a type of gravitational lensing in which the light from a galaxy or star passes a large object, like another galaxy or black hole, and is bent around it. If the alignment is right, the light appears as a ring around the large object.
The galaxy or black hole closest to the observer acts as a lens, bending the light from the galaxy further away.
