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.

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

The European Space Agency's Euclid space telescope, in operation for a few months now, uncovered light coming from a previously unknown galaxy

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.

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

A rare ring of light surrounding a galaxy nearly 590 million light-years away from Earth has been discovered by a space telescope that scientists hope will uncover more cosmic phenomena throughout the universe, the European Space Agency announced on Monday.

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.
