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,

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.

The "dark universe detective" space telescope Euclid has discovered its first Einstein ring in the process, learning about dark matter at the heart of a distant 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.

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.
