What we see here is the farthest-ever view of the universe. The image, known as the eXtreme Deep Field, was assembled over the course of 10 years using photographs taken by NASA’s Hubble Space Telescope.
NASA has described it as a “time tunnel into the distant past,” a look at the universe some 13.2 billion years ago.
Strangely enough, though, while this image showcases a staggering 5,500 galaxies, it only covers a very tiny amount of space from our perspective here on Earth, “a small fraction of the angular diameter of the full Moon.”
