James Webb Telescope captures stunning 'Einstein ring' of two galaxies

(CLO) The latest photo from the James Webb Space Telescope captures a rare cosmic phenomenon called "Einstein ring".

An elliptical galaxy and a spiral galaxy appear as a single celestial body due to the effect of mass on space-time in the universe.

These two objects form a rare phenomenon called an “Einstein ring.” This is the result of light from a very distant galaxy being bent by a larger galaxy positioned between it and the observer. This phenomenon shows that mass can warp light and space-time, but it is invisible on small scales.

However, when a large object like a galaxy or galaxy cluster bends light from a more distant galaxy, we can observe this phenomenon clearly, as in this image.

The elliptical galaxy at the center of the Einstein ring belongs to the galaxy cluster SMACSJ0028.2-7537. It appears as a faint oval halo surrounding a small, bright core.

The lensed spiral galaxy around the elliptical galaxy appears as a bright ring, with blue bands extending in a circular pattern, due to the bending of its spiral arms.

This image was created from data from the James Webb Space Telescope, as part of the "Strong Lensing and Cluster Evolution" (SLICE) survey led by Guillaume Mahler at the University of Liège (Belgium).

This survey aims to study 8 billion years of galaxy cluster evolution by observing 182 galaxy clusters with Webb's near-infrared camera.

Additionally, this image combines data from two Hubble Space Telescope instruments: the Wide Field Camera 3 and the Advanced Camera for Surveys.
