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. The magnified image results from stacks of optical and infrared images taken, respectively, by the Advanced Camera for Survey (ACS) and Wide-Field Camera 3 (WFC3) on board the Hubble. The galaxy has a mass of ~109 times the mass of the Sun and is at a distance of ~13 billion light years from us, forming stars nearly 150 times more rapidly than our galaxy.
