The James Webb Space Telescope brings us this image of an Einstein Ring like no other.
This stunning images features an elliptical galaxy named SMACSJ0028.2-7537 (the egg-yolk-like smooth center) surrounded by rings of light from a distant spiral galaxy, whose light has been bent by the gravitational forces of the foreground galaxy. Multiple blue spirals and even stars of the magnified distant galaxy can be seen in the rings.
Einstein rings are formed when light from a distant object en route to an observer is bent by gravitational forces of an intervening object (e.g., a galaxy or a black hole). This occurs because a massive body bends spacetime, as predicted by Einstein's theory of general relativity. When the lensed object and the lensing object line up just right, the result is the distinctive Einstein ring shape.
The image includes data in infrared light from JWST and in visible light from Hubble.
For comparison, here are a few, not as dazzling, images of Einstein rings taken by the venerable Hubble Space Telescope.
Now let’s use the force of our minds to solve today’s puzzle composed in 1936 by noted Hungarian chess player and composer József Szöghy (1910-1993).
