NASA's latest image from the James Webb Space Telescope depicts an 'Einstein ring,' a stunning embodiment of Einstein's general relativity theory. This phenomenon occurs when light from a distant galaxy is distorted as it passes around another, closer galaxy's mass. This 'gravitational lensing' effect, while subtle in local contexts, becomes clearly visible in cosmic settings, serving as an ideal method to study distant and faint galaxies. The image was captured during the Strong Lensing and Cluster Evolution (SLICE) survey, which aims to trace eight billion years of galaxy cluster evolution.
The latest image from NASA's James Webb Space Telescope showcases an 'Einstein ring', illustrating the gravitational lensing effect predicted by Einstein's theory of general relativity.
When light from a distant galaxy is bent around another, closer galaxy's mass, we observe gravitational lensing—an effect that reveals galaxies too faint to see otherwise.
