"The Hubble Ultra Deep Field, or HUDF, is an image of (just) a small region of space in the constellation Fornax, composited from Hubble Space Telescope data accumulated over a period from September 24, 2003 through to January 16, 2004. It is the deepest image of the universe ever taken by humans. The field imaged by the ACS contains over 10,000 objects, the majority of which are galaxies." (Wiki)
