Candidate for most distant object in the Universe yet observed. November 15, 2012. In this image, astronomers use the NASA/ESA Hubble Space Telescope and a cosmic zoom lens to uncover the farthest known galaxy in the universe. This image is a composite taken with Hubble's Wide Field Camera 3 and the Advanced Camera for Surveys.
