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 theorised that a large gravitational field could act as a lens.

Thanks for watching!
