Deepest Photo Of Space
Updated March 31, 2019
A photo taken by Hubble in 2016 is the "deepest" photo of space - it contains the most distant object discovered so far.
This photo of space being the "deepest" ever means it contains an object further away from Earth than any object photographed so far. The photo was taken in 2016 by the Hubble Space Telescope, and scientists believe this is about as far as Hubble can see.[2] The image contains thousands of galaxies, including one called GN-z11 that is observed at a distance of 13.4 billion light years from us.[1]
The fact that GN-z11 is observed at a distance of 13.4 billion light years, means we see the galaxy as it was 13.4 billion years ago, since it has taken the light from the galaxy that long to reach us. That means we see back in time. We see Gn-z11 as it was "only" 400 million years after the Big Bang, when the universe was only 3 % of its current age.[1] The universe has expanded while the light from GN-z11 has traveled towards us. So today, the distance to the galaxy is believed to be 32 billion light years.[2]
