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 ...

Space telescope spots rare ‘Einstein ring’ of light around galaxy in ... quasars are galactic cores with gas and dust falling into a black hole, releasing a tremendous amount of energy that ...

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 ...

From unifying quantum physics and gravity to working out what is dark matter, the universe has some deep questions that remain unanswered.

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 ...

The Euclid space telescope has captured an Einstein ring, a rare and spectacular phenomenon, around the galaxy NGC 6505. This unprecedented observation opens new perspectives for studying dark matter ...

Einstein rings occur when light from a distant galaxy bends to form a glowing ring around another object in the foreground as that object is being observed. The rarely observed rings are named for ...

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 Euclid space telescope has, by chance, discovered its first Einstein ring, and it is absolutely stunning. Beyond its aesthetic appeal, this perfectly circular Einstein ring has allowed ...
