Einstein predicted the existence of gravitationally-warped rings of light in 1915. Now, a new one has been discovered just a cosmic stone's throw from our own planet.

Einstein rings help scientists study dark matter and cosmic expansion. Euclid will find thousands more lenses to map the Universe’s structure

The structure is nearly 600 million light-years from Earth and is an early display of the nascent dark matter telescope's power.

A European Space Agency telescope has discovered its first "extremely rare" Einstein ring in a galaxy "not too far away" nearly 600 million light years from Earth.

Europe’s Euclid space telescope has detected a rare halo of bright light around a nearby galaxy, astronomers reported Monday. The halo, known as an Einstein ring, encircles a galaxy 590 million light-years away,

Euclid space telescope sent some images back to Earth during an early testing phase. While reviewing the pictures, astronomer and Euclid archive scientist Bruno Altieri found something incredibly rare: an Einstein ring circling a galaxy.

Euclid telescope has located a rare hoop of light called an "Einstein ring" in a nearby elliptical galaxy. Though the galaxy has been on humans' radar for 140 years, its halo is new—and it has a lot to teach Euclid about the dark universe.
