This is a portion of a deep-sky Hubble Space Telescope survey called GOODS North (Great Observatories Origins Deep Survey). The view is a composite of images taken in visible and near-infrared light. Researchers have circled four unusually red objects that appear as they existed just 500 million years after the big bang. They appear red because their light has been stretched to longer infrared wavelengths by the expansion of the universe. These extremely compact and bright galaxies present a puzzle to researchers because they are much more luminous than anything previously seen at such an early epoch. The young galaxies are bright because they are forming stars at a much faster rate than for other galaxies found at such early times.

| About The Image | |
| Color Info | The main GOODS-N composite includes exposures acquired by the ACS and WFC3 instruments on the Hubble Space Telescope. Several filters were used to sample broad wavelength ranges. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are: GOODS-N Blue: F435W (B) + F606W (V) Green: F814W (I) + F850LP (z) Red: F125W (J) + F160W (H) Distant galaxies, inset Blue: F105W Green: F125W Red: F160W |
