Hubble eXtreme Deep Field (XDF) The eXtreme Deep Field (XDF) is the result of millions of seconds of Hubble exposures of a tiny slice of the sky. The thousands of galaxies it reveals stretch from nearly the present day back more than 13 billion years--to just a half billion years after the Big Bang. NASA / ESA / G. Illingworth, D.
