Hubble Space Telescope (HST) found a very bright and distant glaxy thanks to the gravitational lensing of an intervening galaxy cluster. As explained in the news release, "A so-called gravitational lens is produced when space is warped by a massive foreground object, whether it is the Sun, a black hole, or an entire cluster of galaxies. The light from more-distant background objects is distorted, brightened, and magnified as it passes through this gravitationally disturbed region."
The galaxy is the brightest lensed galaxy found to date and it represents a time when the Universe was about 1/3 of its present age. The picture below shows the compnents of the lenses galaxy's image and what the galaxy looks like without the gravitational lensing distortion.
