NASA combined 10 years of Hubble Space Telescope pictures to create a new, improved portrait of mankind's deepest-ever view of the universe.
The extreme deep field - or XDF - is a combination of photos taken of a patch of sky at the center of the original Hubble Ultra Deep Field.
The XDF contains around 5,500 galaxies, the faintest of which are 110-billionth the brightness of what the human eye can see.
It is even more sensitive than the Hubble Ultra-Deep Field.
That is image of a small area of space in the constellation Fornax created using Hubble Space telescope data from 2003 and 2004.
