Distant galaxies in the GOODS North survey
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.
