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.

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.
