A Flight Through the CANDELS Ultra Deep Survey Field Ultra HD

This visualization traverses the CANDLES Ultra Deep Survey (UDS) field to showcase the varied appearances of galaxies and their three-dimensional distribution. The sequence features a dense cluster of galaxies about 6 billion light-years away and extends to galaxies at more than twice that distance. Because the light from these galaxies has travelled for billions of years across space, the images show the galaxies as they appeared billions of year ago. In addition, the expansion of space has redshifted the light of these galaxies towards longer wavelengths (i.e., to the red end of the visible-light region and into the infrared-light region).
