A stunning new image from the James Webb Space Telescope reveals a cosmic mirage known as an Einstein ring, where the light ...
The closer foreground galaxy sits at the center of the image, while the more distant background galaxy appears to be wrapped around the closer galaxy, forming a ring. ESA/Webb, NASA & CSA ...
The foreground galaxy acts like a magnifying lens, bending the travelling light rays due to its gravity. This is called gravitational lensing. If the background galaxy, the lensing galaxy ...
However, in this case, the gravitational field of a massive foreground galaxy cluster not only amplified the light from the background galaxy but also smeared the image into an arc. No other ...
This rare sight, caused by light from a distant galaxy being warped by a massive foreground galaxy ... and the source of the background light. This won't be true in the overwhelming majority ...
In rare cases, when there is an ideal alignment between the observer, the foreground galaxy, and the background galaxy, the phenomenon results in a geometrically perfect distortion of light known ...
