Webb captures perfect Einstein ring that reveals hidden galaxy

  • No comments
A stunning new image from the James Webb Space Telescope reveals a cosmic illusion called an Einstein ring, where the light from a distant galaxy is distorted into a perfect circle by the gravity of a closer galaxy.

This image of the Sombrero galaxy, taken by Webb's Medium AA camera, is shown with compass arrows, a scale, and a color key. The image shows wavelengths of medium AA light translated into visible light colors. The color key shows the filters used when they collected the light. The color of each filter name is the color of the visible light used to represent the AA light passing through that filter. The north and east compass arrows show the direction of the image in the sky. Credit: NASA, ESA, CSA, STScI
