the farthest galaxy observed by astronomers is GN-z11. It is located approximately 13.4 billion light-years away from Earth. This means that the light we receive from GN-z11 today has traveled for 13.4 billion years to reach us, due to the expansion of the universe.
However, it is important to note that our understanding of the universe continues to advance, and new observations may provide more distant galaxies in the future. The field of astronomy is constantly evolving, and scientists are making remarkable discoveries that push the boundaries of our knowledge about the cosmos.
