{"Image ImageDescription": "This image of the Hubble Ultra Deep Field (HUDF) \u2014\u00a0a small region of sky in the direction of the southern constellation Fornax \u2014 shows\u00a0some of the earliest star-forming galaxies in the Universe.  The sensitivity of Hubble's Advanced Camera for Surveys (ACS), combined with the penetrating power of the Near Infrared Camera and Multi-Object Spectrometer (NICMOS) have finally revealed these long-sought after faint galaxies. Some of these faint objects\u00a0are less than one four-billionth the brightness of stars that can be seen with the naked eye and their light has taken nearly 13 billion years to reach Earth."}
