Chat GPT on the image : "Here is the COSMOS-Web Ring, one of the most distant Einstein rings revealed by #JWST.
In this composite image  (R = 4.44 µm, G = 2.77 µm, B = 1.50 + 1.15 µm), the massive lens in the foreground distorts the light from a background galaxy into an almost complete circle of light. Each green bead traces a star nursery, magnified and duplicated by general relativity".
