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.

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.

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.

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.

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.
