This image from the Hubble Space Telescope CANDELS survey highlights the most distant galaxy in the universe with a measured distance, dubbed z8_GND_5296. The galaxy's red color alerted astronomers that it was likely extremely far away and, thus, seen at an early time after the Big Bang. A team of astronomers from the University of Texas at Austin and Texas A&M University measured the exact distance using the Keck I telescope with the new MOSFIRE spectrograph. They found that this galaxy is seen at about 700 million years after the Big Bang when the universe was just 5% of its current age of 13.8 billion years.
