Third image of galaxy hosting most distant known star
The galaxy containing the most distant star known so far is visible three times in the galaxy cluster MACS j1149.5+223. The multiple images are created through the process of strong gravitational lensing.
While two of the images of the galaxy are close to the centre of the galaxy cluster, this third image is farther out and almost undistorted.
