A new image shows how the light from a quasar billions of light years away is bent around a foreground galaxy by the curvature of space. This light has been traveling for 9 billion years before it reached the Earth. The quasar is a galaxy powered by a super-massive black hole, leading to the ejection of jets of matter moving at almost the speed of light.
