thick ring surrounding the black hole, which is consistent with the expected appearance of a Kerr black hole—a solution to Einstein's equations that describes rotating black holes. This finding ...

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 ...

The European Space Agency’s (ESA) Euclid space telescope has discovered an extremely rare Einstein ring. Einstein rings of light are produced when two galaxies are almost perfectly aligned ...

Black holes continue to captivate scientists: they are purely gravitational objects, remarkably simple, yet capable of hiding mysteries that challenge our understanding of natural laws. Most ...

Astronomers with the European Space Agency’s Euclid mission have captured an unprecedented look at a rare cosmic phenomenon — and they made the observations purely by happenstance. Einstein ...

One of the key areas of investigation is the Kerr ... black holes to two-dimensional CFTs. For instance, studies have shown that the properties of rotating dyonic black holes in the Einstein ...

"These observations provide a more complete picture of the black hole's environment ... made using Albert Einstein's theory of gravity, general relativity. That ring was still present in the ...

The halo, known as an Einstein ring, encircles a galaxy 590 million light-years away, considered close by cosmic standards. A light-year is 5.8 trillion miles. Astronomers have known about this ...

C. Cuillandre, T. Li) The European Space Agency (ESA) has released a spectacular image of an Einstein ring – a circle of light formed around a galaxy by gravitational lensing. Taken by the €1.4bn ...
