The James Webb Space Telescope has revealed a rare "Einstein ring," revealing two distant galaxies in an optical illusion ...

But perhaps the most beautiful effect of gravitational lensing is what's known as an Einstein Ring. This is where the distant galaxy is so perfectly centered behind the closer galaxy that its ...

"The picture features a rare cosmic phenomenon — an Einstein ring. What appears to be a single, strangely shaped galaxy is actually two galaxies far apart," the European Space Agency explained online.

“An Einstein ring is an example of strong gravitational lensing,” says lead author Conor O’Riordan of the Max Planck Institute for Astrophysics. “All strong lenses are special, because ...

This is called gravitational lensing. If the background galaxy, the lensing galaxy, and the telescope are perfectly aligned, the image appears as a ring – called an Einstein ring. Einstein rings ...

The strange sight is actually two galaxies, with the light of the second warped around the one at the front as a result of its massive gravity.

This is called an Einstein Ring, named after scientist Albert Einstein, who predicted this effect in his Theory of Relativity.

This gravitational lensing effect was predicted by Einstein and has since become an important tool in astrophysics. Gravitational lensing has numerous applications, e.g. in the search for extrasolar ...
