CAPE CANAVERAL, Fla. (AP) — 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, considered close by cosmic standards. A light-year is 5.8 trillion miles.

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.

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.

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.
