GOODS-S/ERS2 Field (Hubble)
This is a Hubble Space Telescope view of a portion of GOODS-South, the southern field of a large deep-sky study by several observatories to trace the formation and evolution of galaxies. The image shows a rich tapestry of 7,500 galaxies stretching back through most of the universe's history. The farthest galaxies, a few of the very faint red specks, are seen as they appeared more than 13 billion years ago, or roughly 650 million years after the Big Bang. Soon, the James Webb Space Telescope will peer back even farther into this field to trace the formation and evolution of the very first galaxies.

The image is a composite of separate exposures made by the WFC3 and ACS instruments on the Hubble Space Telescope. In total, 10 filters were used to sample a very wide wavelength range. The color results from assigning different hues (colors) to combinations of the monochromatic images. In this case, the assigned colors are: Red: WFC3/IR F125W + F160W Green: ACS/WFC F606W + F775W + F850LP + WFC3/IR F098M Blue: WFC3/UVIS F225W + F275W + F336W + ACS/WFC F435W
