Euclid telescope captures Einstein ring revealing warping of space
Dazzling image shows galaxy more than 4bn light years away, whose starlight has been bent due to gravity
Albert Einstein’s general theory of relativity predicts that light will bend around massive objects in space, meaning that galaxies can act as vast lenses. Ultimately the telescope, which can detect galaxies out to 10bn light years, is aiming to create the largest cosmic 3D map ever made. “I find it very intriguing that this ring was observed within a well-known galaxy, which was first discovered in 1884,” said Dr Valeria Pettorino, ESA Euclid project scientist.
