A Giant Lensed Galaxy Arc


This image shows one of the most striking examples of gravitational lensing, in which the gravitational field of a foreground object bends, distorts, and amplifies the light of a more distant background object. The view of a distant galaxy (nearly 10 billion light-years away) has been warped into a nearly 90-degree arc of light by the gravity of the galaxy cluster known as RCS2 032727-132623 (about 5 billion light-years away).
