Einsteins famous cross the einstein cross is actually four images of a single quasar the image in the center is not visible to the unaided eye.
When the lensing approaches perfect symmetry a complete or almost complete circle of light is produced called an einstein ring.

Gravitational lensing einstein ring. Gravitational lensing is most effective meaning the ring radius is largest when the lensing object is half way between us the and background source. Animation demonstrating how the gravity from a massive foreground galaxy can bend the light of a more distant galaxy. Einstein rings are a particularly interesting manifestation of gravitational lensing producing spectacular arcs and rings from distorted galaxies and stars. These are called einstein rings named of course for the scientist whose work predicted the phenomenon of gravitational lensing.
If the two galaxies line up just right the result is a highly distorted image of the distant galaxy known as an einstein ring. Due to gravitational lensing the light is diverted making it seem to come from different places. If source lens and observer are all aligned the light appears as a ring. More complex gravitational lensing arises in observations of massive clusters of galaxies.
This results in an einstein ring. It also depends on the distance between us the lensing object and the background source. The first was discovered in the radio waveband by hewitt et al 1987. Gravitational lensing is predicted by albert einsteins theory of general relativity.
The graceful arcs at the center of this image from the hubble space telescope are actually the distorted light of distant galaxies twisted to form an einstein ring by the gravitational. In that event the einstein ring radius is given by this equation. A above shows the result when y 0. From nrao outreach pro.
An einstein ring also known as an einsteinchwolson ring or chwolson ring is created when light from a galaxy or star passes by a massive object en route to the earth. Animation of a gravitational lens creating an einstein ring. 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 towards the observerthis effect is known as gravitational lensing and the amount of bending is one of the predictions of albert einsteins general theory of relativity.
