Astronomers using the powerful James Webb Space Telescope to survey distant galaxies spotted an unusual, chance phenomenon called an "Einstein ring." It's not an actual object, but a warped ...

One of the first verified predictions of general relativity is the gravitational deflection of starlight. The effect was first observed in 1919 during a total solar eclipse. Since stars appear as ...

A jaw-dropping new space image shows one galaxy hiding behind another. The rare cosmic phenomenon, called an Einstein ring, occurs when massive objects can bend light due to their gravitational ...

So much so that the cosmic phenomenon is called an "Einstein ring." Einstein rings happen when light from one distant object is bent around the mass of another, slightly closer and even larger object.

The NASA James Webb Space Telescope captured a stunning image of an Einstein ring, an optical phenomenon created by gravitational lensing. This rare sight, caused by light from a distant galaxy ...

and the James Webb Space Telescope took another pretty picture of an Einstein ring: Geologists at the University of Texas at Austin report that the underside of the North American continent is ...
