A rare Einstein ring spotted near our galaxy offers a unique chance to test Einstein’s general relativity and study the warping of space-time.

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.
