The oldest and therefore furthest known galaxy we have discovered is over 13.7 billion light years away. It's called z8_GND_5296. The light has taken so long to reach us that the star which collapsed to form the gas that Sun is made out of wasn't "born" yet. Galaxies this far away from help astronomers understand the very early universe and how it has evolved over time. Due to the expansion of space, the distant galaxy pictured here technically wouldn't be there anymore and would actually be “currently 13.1 Giga light-years away from us. or 4.0×109 pc."
