EXTREME Deep Field
A better, more in-depth version of a classic. Adding to the deepest picture of the cosmos ever taken back in 2004, called the Hubble Ultra Deep Field, the Hubble team collected even fainter light in this 2012 XDF photo, enabling new studies about the early universe and blowing our minds even more. We've counted over 5,500 galaxies! All this in such a tiny fraction of our night sky near the constellation Fornax.
