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 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, astronomers reported Monday.

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

An Einstein ring is light from a much more distant galaxy that bends in such a way as to perfectly encircle a closer object.

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.

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.
