An international team of astronomers has discovered the most distant galaxy in the universe to date. They found it by combining the unique sharpness of the Hubble telescope with the light-collecting power of the W. M. Keck Telescopes- with an added boost from a gravitational lens in space.

The results show the young galaxy is as far as 13 billion light-years from Earth, based on an estimated age for the universe of approximately 14 billion years. The Hubble picture at left shows the young galaxy as a red crescent to the lower right of center. The galaxy's image is brightened, magnified, and smeared into this arc-shape by the gravitational influence of an intervening galaxy cluster, which acts like a gigantic lens. The image at upper right is a close-up of the "gravitationally lensed" galaxy. In the picture at lower right, astronomers have "unsmeared" the galaxy, revealing the galaxy's normal appearance.
