The most distant known galaxy to host a supermassive black hole has been discovered in a galaxy that formed in the early history of the universe. The galaxy, as large as the Milky Way, is about 12.8 billion light-years away and harbors a supermassive black hole that contains at least a billion times as much matter as our sun.

Public release of a VO-oriented and SQL-queryable database for studying the evolution of galaxies in the ΛCDM cosmogony
Just days after NASA released the first cosmic dreamscapes taken by the newly refurbished Hubble Space Telescope three teams of astronomers have used the rejuvenated observatory to find what appears to be a bounty of the most distant galaxies known.
Together with ever-improving observations of the early universe, grand simulations are beginning to paint a single, unifying picture of why the universe looks as it does. At its heart is an almost invisible scaffold of dark matter and cold gas on which the visible constituents of the universe hang - a structure known as the cosmic web.
