The most distant galaxy ever observed

The most distant galaxy ever observed is estimated to be around 13,000,000,000 light-years away. Discovered by the Hubble Space Telescope in 2004, it is located behind the galactic cluster Abell 2218, which bends the object's light. It is a small, energetic galaxy whose light that is seen on Earth now would have set out when the universe was just 750 million years old. This is the most distant object that can be observed consistently; some ephemeral gamma-ray bursts have been observed that are slightly more distant than this object.
