CANDELS Dwarf Galaxies
The CANDELS team identified 69 dwarf galaxies that are undergoing intense bursts of star formation. The dwarf galaxies were found in two regions of the sky called the Great Observatories Deep Survey-South and the UKIDSS Ultra Deep Survey (part of the UKIRT Infrared Deep Sky Survey). Each dwarf is shown centered in cutouts made from near-infrared (I, J, and H band) images acquired by Hubble's Wide Field Camera 3 and Advanced Camera for Surveys. The light from these galaxies has been traveling for about 9 billion years. Many of the stars in nearby dwarf galaxies may have formed in similar starbursts around the same time. The background shows a wider near-infrared view of the CANDELS Ultra Deep Survey field.
