You might think that the Einstein ring is the large fuzzy halo around the bright white elliptical galaxy nucleus in that wide-field Euclid image, but itโs not.
The ring is small & tight around the nucleus. Itโs hardly visible at all with the contrast in the main image, but easy once you play with the original data & extract it, as ESA did for this zoomed-in shot.
Except the Guardian photo editors didnโt use it as no-one made it clear to them.
