A stunning new image from the James Webb Space Telescope reveals a cosmic mirage known as an Einstein ring, where the light ...

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 ...

This week, researchers reported on nine rivers and lakes in the Americas that defy hydrologic expectations. Geologists report ...

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 ...

This "rare cosmic phenomenon", called an Einstein ring, appears as a single eye-like orb in the darkness of space, but is actually a distorted view of two distant galaxies in the constellation Hydrus.

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.

James Webb Space Telescope (JWST) has captured a stunning photograph of an Einstein ring. The European Space Agency (ESA) and the Canadian Space Agency (CSA) shared this unusual sighting to the public ...
