Hubble CANDELS Field Image with Galaxy z8_GND_5296

October 23, 2013
This image from the Hubble Space Telescope CANDELS survey highlights the most distant galaxy in the universe with a definitively 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 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 percent of its current age of 13.8 billion years. Credit: NASA, ESA, V.
