The Hubble Space Telescope has shattered the record for the furthest galaxy ever found. Galaxy GN-z11 formed shortly after the Big Bang, and the light from it has taken a whopping 13.4 billion years to reach us. Scientists must now rethink their theories about the early universe.
Astronomers are excited, but know that this discovery approaches the limit of Hubble's technical capabilities. To look even further into space - and therefore further back in time - they will need to wait for the much larger James Webb Space Telescope, due to launch in 2018.
