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.

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

Euclid, a space telescope on a mission to uncover the secrets of dark matter and dark energy, has already made a stunning discovery: a perfectly formed Einstein ring hidden in a well-known galaxy. This rare phenomenon,

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

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 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.

A Euclid space telescope has spotted a rare halo of bright light known as an "Einstein Ring" in a galaxy not so far, far away.
