In order to explain this, in 1905, Einstein suggested in Annalen der Physik that light comprises quantized packets of energy, which came to be called photons. It led to the theory of the dual nature ...

Astronomers have identified the closest ever Einstein ring, a rare phenomenon where light from a further-off galaxy is bent by the gravity of a galaxy closer to Earth. The ring was previously ...

Einstein’s general theory of relativity predicts that light will bend around objects in space, so that they focus the light like a giant lens, with this effect being bigger for massive galaxies.

When it comes to space travel, Albert Einstein's theory of relativity is a major inconvenience. With the laws of physics (currently) prohibiting faster-than-light travel, velocities are limited to ...

A stunning halo of light in a nearby galaxy has been captured by Europe's Euclid space telescope. Known as the "Einstein ring," the halo exists in a galaxy about 590 million light-years away ...

Europe's Euclid space telescope has detected a rare ring of bright light around a nearby galaxy, astronomers have said. The halo, known as an "Einstein ring," encircles a galaxy 590 million light ...
