This image, taken with the Wide Field Camera (WFC3) on the Hubble Space Telescope, shows thousands of galaxies in various stages of evolution. The galaxies we see here span more than 12 billion years of cosmic history. If our present understanding of dark energy is correct, the larger the universe becomes, the faster it will expand. The galaxies we see now will be redshifted out of view in the very distant future, leaving each galaxy isolated from all the rest. (Unit: 11)
