#UMPlus - Einstein Ring in Hydrus
https://www.universomagico.net/2025/04/anillo-de-einstein-en-hydrus.html
The James Webb Space Telescope has captured a rare cosmic phenomenon called the Einstein Ring. What at first appears to be a single, oddly shaped galaxy is actually two galaxies separated by a great distance. The closer foreground galaxy is at the center of the image, while the more distant background.....
