Ultra Deep Field

Dubbed the Hubble Ultra Deep Field, this image is actually a combination of two separate images that provide astronomers with the deepest look into the universe that has ever been achieved by mankind. Galaxies that have never been seen before, even by Hubble, were discovered with the help of this million-second-long exposure image.
