 This Hubble image shows a massive galaxy cluster about 4.6 billion light years away. Along its border, four bright arcs are visible. These are copies of the same distant galaxy nicknamed the Sunburst Arc. It's almost 11 billion light years away. Its light is being lensed into multiple images by strong gravitational lensing. The Sunburst Arc is among the brightest lensed galaxies known. And its image is visible at least 12 times within the four arcs. Here's a closer look at three of them. The lens makes various images from 10 to 30 times brighter. This allows Hubble to view structures as small as 520 light years across. A rare detailed observation for an object that far away.
