They are one of the best examples we have of gravitational lensing–a phenomenon that Albert Einstein predicted in 1915. The ring and other findings are detailed in a study published February 10 ...

Galactic lenses like this one, which is the closest astronomers have ever found, were predicted by Albert Einstein in 1936 from his theory of general relativity. At the time, he thought such an ...

The rarely observed rings are named for mathematician and physicist Albert Einstein. His general theory of relativity predicted that light could bend and brighten around objects across the cosmos.

Gravity distorted the light from this more distant galaxy, thus the name honoring Albert Einstein. The process is known as gravitational lensing. This photo provided by the European Space Agency ...
