This image begins with a zoom sequence into the location of the Hubble eXtreme Deep Field (XDF), the deepest image of the cosmos ever made. It ends with a flythrough, showing the relative positions of these galaxies, based on redshift information derived from Hubble data. Note that the perspective has been compressed.
