This NASA Hubble Space Telescope image reveals one of the faintest and probably farthest clusters of galaxies ever seen. The cluster contains about 30 very faint objects which are unusually small and compact in appearance. (The larger objects are foreground galaxies located in a separate galaxy cluster four billion light-years away). These lumpy spots do not appear to resemble the elliptical and spiral galaxies of today. The objects might not be separate galaxies but rather sites of strong star formation embedded within primordial galaxies which are too faint to be seen in this HST exposure.
