This new image of the Hubble Ultra Deep Field (HUDF) 2012 campaign reveals a previously unseen population of seven faraway galaxies, which are observed as they appeared in a period 350 million to 600 million years after the Big Bang. The galaxy census is the most robust sample of galaxies ever found at these early epochs. The galaxies were seen in near-infrared light using Hubble's Wide Field Camera 3. // Credit: NASA/ESA/R.
