CANDELS galaxies

CANDELS galaxies

A small portion of one of the CANDELS fields; small circles indicate galaxies included in the survey. Galaxies seen at various distances are circled in colors according to epoch. Galaxies at a redshift of 4, or 1.5 billion years after the Big Bang, are circled in magenta, while galaxies at 5, 6, 7 and 8 are circled in blue, green, yellow and red, respectively. The three insets show a zoomed in view of three galaxies; the upper-left panel is one at a redshift of 4, the lower-right is at a redshift of 6, and the lower-left is at a redshift of 7.

This composite image is made up of an optical image (shown in blue) by Hubble Space Telescope as part of the GOODS survey, combined with an infrared Hubble image (red and green) taken in dedicated CANDELS observations.
