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.

1 day ago · An Einstein Ring is a ring of light around a form of dark matter, galaxy or cluster of galaxies, says Mustapha Ishak, an astrophysics professor at the University of Texas at Dallas. When light ...

2 days ago · “An Einstein ring is an example of strong gravitational lensing,” explained Conor O’Riordan, of the Max Planck Institute for Astrophysics, Germany, and lead author of the first scientific paper analyzing the ring. A strong gravitational lens produces multiple images of a background source that may appear as arcs, forming a ring like this ...

2 days ago · The Einstein Ring, an extremely rare phenomenon, turned out to be hiding in plain sight in a galaxy not far away. The galaxy, called NGC 6505, is around 590 million light-years from Earth, a stone’s throw away in cosmic terms. But this is the first time that the ring of light surrounding its centre is detected, thanks to Euclid’s high ...

1 day ago · Einstein rings occur when light from a distant galaxy bends to form a glowing ring around another object in the foreground as that object is being observed. The rarely observed rings are named for ...

2 days ago · Einstein rings are a rich laboratory for scientists to explore many mysteries of the universe. For example, an invisible form of matter called dark matter contributes to the bending of light into a ring, so this is an indirect way to study dark matter. Einstein rings are also relevant to the expansion of the universe because the space between ...
