Einstein Ring Spotted by Hubble
Einstein Ring Spotted by Hubble
This image, taken with the Hubble Space Telescope, shows a distant galaxy located in the constellation Fornax. It is the largest and one of the most complete Einstein rings ever discovered.
This object’s unusual shape is the result of gravitational lensing. Albert Einstein, in his general theory of relativity, first theorized that a large gravitational field could act as a lens.
