Astronomers discover rare Einstein ring, aiding tests of general relativity and mapping the universe.
Astronomers using the Euclid space telescope have discovered an Einstein ring, a rare phenomenon where gravity bends light from a distant galaxy into a ring shape. The ring surrounds a galaxy 500 million light years away, with the light coming from a galaxy 4.42 billion light years away. This discovery, published in Astronomy and Astrophysics, allows scientists to test Albert Einstein's theory of general relativity and aids the Euclid mission in creating a 3D map of the universe.
