An Einstein Ring is a special case of gravitational lensing, caused by the exact alignment of the source, lens, and observer. This results in symmetry around the lens, causing a ring-like structure. [2] The geometry of a complete Einstein ring, as caused by a gravitational lens. The size of an Einstein ring is given by the Einstein radius.
The Einstein ring, formed as light from a distant galaxy bends to glow around another object in the foreground, could help solve the universe’s mysteries. Space telescope reveals rare ...
Although Einstein made unpublished calculations on the subject, [9] the first discussion of the gravitational lens in print was by Khvolson, in a short article discussing the "halo effect" of gravitation when the source, lens, and observer are in near-perfect alignment, [7] now referred to as the Einstein ring.

A new photograph from the Hubble Space Telescope shows a stunning “Einstein Ring” billions of light-years from Earth — a phenomenon named after Albert Einstein.
The main lens lies at redshift z = 0.222, with the inner ring at z = 0.609 with an Einstein radius R E = 1.43 ± 0.01" and magnitude m = 19.784 ± 0.006, the outer ring is at z ≲ 6.9 with R E = 2.07 ± 0.02" and magnitude m = 23.68 ± 0.09 [1] The lensing galaxy is also known as SDSSJ0946+1006 L1, with the nearer lensed galaxy as SDSSJ0946 ...
The Einstein radius is the radius of an Einstein ring, and is a characteristic angle for gravitational lensing in general, as typical distances between images in gravitational lensing are of the order of the Einstein radius.
Penrose diagram of an infinite Minkowski universe, horizontal axis u, vertical axis v. In theoretical physics, a Penrose diagram (named after mathematical physicist Roger Penrose) is a two-dimensional diagram capturing the causal relations between different points in spacetime through a conformal treatment of infinity.
