ikenbot: Brightest Galaxy Ever Seen With Gravity Lens Shines in Hubble Photo A fluke of astrophysics has revealed what scientists are calling the brightest galaxy ever seen through a cosmic “zoom lens,” NASA officials say. The distant galaxy is 10 billion light-years from Earth and was spotted by the Hubble Space Telescope using a so-called gravitational lens created by a massive cluster of closer galaxies located about 5 billion light-years away. The distant galaxy is three times brighter than any other seen through a gravity lens, researchers said. “This observation provides a unique opportunity to study the physical properties of a galaxy vigorously forming stars when the universe was only one-third its present age,” NASA officials explained in a statement released Thursday (Feb. 2). The universe is currently about 13.7 billion years old. A gravitational lens is created when a massive object, like a black hole or galaxy cluster, falls in between an observer (like the Hubble telescope) and a more distant target in the background.
