"They're so rare, and they're incredibly useful scientifically," said Conor O'Riordan of the Max Planck Institute for Astrophysics.

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 ...

Europe’s Euclid space telescope has detected a rare halo of bright light around a nearby galaxy. The halo, known as an ...

The ring of light, known as an Einstein Ring, was discovered in September 2023 by Euclid, a space telescope on a six-year mission to map out the cosmos by observing billions of galaxies.

"Even from that first observation, I could see it, but after Euclid made more observations of the area, we could see a perfect Einstein ring. For me, with a lifelong interest in gravitational ...

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 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 ...
